5 X-RING CHAIN Grease is sealed with X-Rings between pin and bushing. The X-Ring design offers greater protection than the previous O-Ring design. It can be used in a very wide range of applications from low speed to high speed and from light duty to heavy duty, ensuring longer life. Furthermore, it is durable to some extent even at high temperature, and a chain adopting heat resistant X-Rings has actually been used in a 200º C oven. Since the pin length becomes longer by two X-Rings, refer to the catalogue for dimensions. SPECIAL LUBRICATION ROLLER CHAIN UR CHAIN Sintered Bushing roller chain uses bushings made of sintering alloy steel powder. The porous spaces of the sintered bushings are impregnated with oil before hand, to increase the life of the chain. However, sintered bushing roller chains are for low speed and light duty applications. LU CHAIN B.S. British Standard 08BL 10BL 12BL 16BL The LU chain has a film of fine crystallite that absorbs oil well. This chain is most suitable where splattering of oil and grease must be avoided. LU chain coated with grease improves wear and resistance to corrosion. Temperatures up to +120 C.

Hence it has improved tensile strength compared with roller chain and better suited for suspension and tension. D.I.D. leaf chains are in accordance with ANSI standard and are available in two alternatives of AL type and BL type. AL Series BL Series AL Used primarily for light duty and slow speed applications, where little importance is attached to wear resistance. BL Used for repetitive high impact loading applications, where more importance is attached to wear resistance. AL4xx 1/2" AL5xx 5/8" AL6xx 3/4" AL8xx AL10xx AL12xx 1 1/2" AL14xx 1 3/4" AL16xx 2" xx = Lacing BL4xx BL5xx BL6xx BL8xx BL10xx BL12xx BL14xx BL16xx 1/2" 5/8" 3/4" 1 1/2" 1 3/4" 2" NICKEL PLATED CHAIN E.K. Rustless chain is an outstanding corrosion resistant chain because its surface is nickel plated. Rustless chain without grease has less performance than LU chain. However, the chain with grease shows good anti-corrosion performance. In a situation where chain is exposed to the possibility of hydrogen embrittlement caused by acid vapour or salty environment, nickel plating delays the corrosive effect on the chain. B.S.

11 RRS TYPE - Lovejoy The RRS coupling is based on the standard Lovejoy Jaw type coupling. The center drop out section of this coupling provides proper shaft separation while also allowing easy elastomer installation without disturbing the hubs or requiring realignment of shafts. Designed for the pump industry, it accommodates metric standard pump/motor shaft separations. The drop out spacer is made of glass reinforced plastic, cast iron or aluminium. COUPLINGS C TYPE - Lovejoy These couplings provide standard shaft-to-shaft connection for medium duty range applications. The standard C coupling hub is made of cast iron. The coupling uses a set of SXB cushions instead of a spider. The load cushions are held in place radially by a steel collar which is attached to one of the hubs. The cushion design has the same engineering purpose as the spider design but is more effective in the medium duty applications that C Type couplings address. CURVED JAW - Lovejoy This design is the European standard jaw coupling, as well as in many other parts of the world. When equipment from overseas is used in Australia, Naismith Engineering can provide the replacement flexible couplings and elastomers. These couplings require no lubrication and provide highly reliable service for light, medium and heavy duty electrical motor and internal combustion power transmission applications. Other features and benefits include: Fail-safe - will still perform if elastomer fails. No metal to metal contact. Resistant to oil, dirt, sand, moisture and grease. S-FLEX - Lovejoy The simple design of the S-Flex coupling ensures ease of assembly and reliable performance. No special tools are needed for installation or removal. S-flex couplings can be used in a wide variety of applications. The S-Flex coupling is comprised of three parts:- two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. It is available in pilot bore, taper bore and also as a spacer coupling. Other features and benefits include: No metal to metal contact. Resistant to oil, dirt, sand, moisture and grease. Dampens vibrations and controls shock. Torsionally soft. PAGE 13

12 SHAFT COUPLINGS L TYPE - Lovejoy The Jaw Type couplings from Lovejoy are offered in the industry's largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium and heavy duty electric motor and internal combustion power transmission applications. Hubs can be used with inserts in 4 different materials: Buna-N (Sox), Urethane, Hytrel and Bronze. Other features and benefits include: Fail-safe - will still perform if elastomer fails. No metal to metal contact. Resistant to oil, dirt, sand, moisture and grease. AL & SS TYPE - Lovejoy AL TYPE The aluminium construction means this coupling is light weight with low overhung load and low inertia. The AL type also offers excellent resistance to atmospheric conditions, so it is perfect for corrosive environment applications. Hubs can be used with inserts in 4 different materials: Buna-N (Sox), Urethane, Hytrel and Bronze. SS TYPE Stainless steel construction gives maximum protection to corrosive atmospheric conditions. Hubs can be used with inserts in 4 different materials: Buna-N (Sox), Urethane, Hytrel and Bronze. Lovejoy s SS-type jaw coupling offers a new level of affordability and availability. LS & CS TYPE JAW IN-SHEAR - Lovejoy The spider is non-fail-safe and thus acts as a fuse to prevent equipment damage in the event of torque overloads. It is radially removable, meaning that neither hub (or driver/driven equipment) has to be moved to replace the spider. This saves time and money in maintenance costs. The retaining ring which encloses the In-Shear Spider has 6 Pins which slide into grooves in the perimeter of the spider and twist-lock into place. It will not work its way loose and since there are no fasteners involved, maintenance removal of the spider takes only a few minutes. This coupling uses the standard L-type and C-type jaw coupling hubs. Existing applications using in-compression spiders can simply be retrofitted with the new In- Shear spider if the features are beneficial. The Jaw In-Shear spider is made from urethane and has different power ratings to the standard jaw coupling. It also uses different service factors. PAGE 12

13 SLIDE BLOCK - D.O.M. The Polyethylene Slide Block is available for use with British Standard simple, duplex and triplex chains. The assembly is supplied with a bolt set to suit. It is normally used in slower speed applications and has an operating speed range up to 20m/min and a o maximum working temperature of +70 C. CHAIN & BELT TENSIONERS OVR & XOV SLIDE BLOCKS - D.O.M. The OVR & XOV Slide Blocks are available for use with British Standard simple chain. They are oval in shape allowing you to use both sides of the slide block giving double the life of a standard unit. Both are made in machined polyethylene HD100 and the XOV comes complete with stainless steel nuts and bolts. British Standard duplex and triplex chains can be accommodated by simply bolting 2 or 3 slide blocks together. VIB - D.O.M. D.O.M. make a large range of damping and anti-vibration mounting units. Using the same basic principle as the tensioner arms, the anti-vibration mounting units come in more than twenty different designs and can be used with many different mounting brackets. The list of applications where you can use them is almost endless, from motor mounts and cushions for crushing machines to anti-vibration laboratory equipment. They may also be used as the pivots for a shaker bed. CHAIN TENSIONER - Sit S.p.A. The TA model from SIT represents the basic model of the range and consists of a body in alloy, containing the elastic elements, and a lever in galvanized steel. The alloy body can be one of two according to size; TA1, the smallest, and TA2. The SIT chain tensioner device in the TA-RDF & TA-RDR models consists of a TA tensioner and a sprocket mounted on a watertight ball bearing. To use with duplex or triplex chains requires the assembly of a special series of sprockets. TA-RDF Sprockets are axial fixed. TA-RDR sprockets are axial adjustable. PAGE 11

14 COUPLINGS SIER-BATH GEAR C & CFR - Lovejoy C TYPE (FLEX - FLEX) The C type is the basis for all types of Lovejoy Sier-Bath continuous sleeve flexible gear couplings. It is suitable for most applications. Gear teeth are precision cut at 20 degrees pressure angle with minimum backlash, and are smaller for even distribution of load, greater capacity and longer life. CFR TYPE (FLEX - RIGID) The flex-rigid gear coupling consists of a flexible hub and a rigid hub with a single sleeve. The flexible hub is a standard hub from a flex-flex coupling. The rigid hub uses a splined type hub. The flex-rigid coupling accommodates angular misalignment only and does not allow for parallel misalignment. SIER-BATH GEAR F & FFR - Lovejoy F TYPE (FLEX - FLEX) Double engagement provides for parallel misalignment, angular misalignment and end float with the ability to accommodate close coupled application requirements. FFR TYPE (FLEX - RIGID) Single engagement accommodates angular misalignment only and does not allow for parallel misalignment. This design consists of a flexible and rigid half, most commonly used in floating shaft applications to solve remote drive and excessive misalignment problems. FA couplings in 4140 Alloy Steel, and FLA couplings with Metal Labyrinth Seals are also available. GRID - Lovejoy The Lovejoy Grid type flexible coupling reduces vibration by as much as 30%, and cushions shock loads to safeguard your driving and driven equipment. The flexible nature of the spring like grid absorbs impact energy by spreading it out over time, thus reducing the magnitude of the peak loads. This is possible because of the progressive contact that occurs between the curved profile of the hub teeth and the flexible grid. Grid couplings are designed for versatility. Common hubs and grids are used within a given size range for both horizontal and vertical split cover models. Grid installation and replacement is a 'snap', making maintenance very easy. JAURE DISC - Lovejoy The Lovejoy/Jaure disc coupling is a great low maintenance coupling. It has been developed using the latest technology, Finite Element Analysis, to create a high torque, long life coupling. The discs are made from a high-grade stainless steel, ensuring not only a high strength and high endurance to fatigue, but also resistance to most chemicals. Furthermore, the discs can be covered with a low coefficient of friction coating to improve the resistance to fretting wear, which is the biggest cause of disc coupling failure. Disc couplings to meet A.P.I. 610 available on request. PAGE 16

15 MINI SOFT - Lovejoy The Mini Soft miniature coupling from Lovejoy provides protection from misalignment, vibration and shock loads. The simple design of the coupling ensures ease of assembly, installation and reliable performance. No special tools are needed for installation or removal. No lubrication is needed and once installed and aligned correctly, no maintenance is required. Other features and benefits include: Multiple tooth contact, low load per tooth. Good axial freedom. Good dampening capacity. Good torsional stiffness. High speed capability. COUPLINGS OLDHAM - Lovejoy The Lovejoy Oldham coupling is a precision engineered, torsionally stiff, three part coupling. It is suitable for a great many applications ranging from incremental control of fluid valves to highly dynamic drives in a closed loop servo system. It accommodates misalignment mechanically through a floating disc that engages tenons machined out of the hubs. Under severe overload the element will break cleanly, and act as a mechanical fuse to protect equipment. Other features and benefits include: Positive engagement. Good parallel misalignment capacity. Vibration damping ability. Easy to install. SAGA - Lovejoy Saga is a general purpose torsionally soft coupling with high tolerance to all forms of misalignment. The rubber between each apex is precompressed, so it is much more durable to the stresses arising from the various forms of misalignment and torsional vibrations. Other features and benefits include: No end thrust in misalignment position. Absorbs misalignment and shock. No axial reaction force. DELTA FLEX - Lovejoy The unique design, misalignment capability and simple installation, make Deltaflex easily adaptable to special applications. This is an all metal coupling and is also available in stainless steel. High misalignment capability means that there is less reactionary load on the rest of the machine. Other features and benefits include: Operates smoothly when misaligned. No lubrication. No backlash. Many standard coupling configurations for application versatility. PAGE 15

18 COUPLINGS N & SWN TYPE - Nenflex N TYPE The N type is the most common shaft to shaft jaw coupling around with star shaped spider. Made to industry standard and available in a wide range of bore sizes. SWN TYPE The SWN type is a shaft to shaft jaw coupling with all the advantages of the N series but with the wrap around element and retaining collar. The wrap around insert from Nenflex has the following advantages. - Special shape profile which does not result in a 100% contact at no load condition & thereby prevents heat build up & hysteresis failure. - Spacer ribs no longer require gaps to be maintained during assembly. - Vertical ribs grip the wrap around element firmly within the steel retaining ring. Spiders available in rubber and urethane. CWN TYPE - Nenflex CWN Series The CWN type is a shaft to shaft jaw coupling with T-insert elements and retaining collar. The T-inserts are specially designed for ease of installation and removal. The CWN series is used for higher power requirements than the N or SWN series. Also available with standard rubber spider. Inserts available in rubber and urethane. HN Series Nenflex also offer a larger capacity coupling for bores to 150mm and torque of up to 13,000Nm SPACER TYPE - Nenflex SWR SERIES The SWR type is a spacer coupling ideal for shaft to shaft connection. Ideally suited to pump applications, as the spacer can be removed radially, without disturbing driver or driven equipment. The wrap around insert from Nenflex has the following advantages. - Special shape profile which does not result in a 100% contact at no load condition & thereby prevents heat build up & hysteresis failure. - Spacer ribs no longer require gaps to be maintained during assembly. - Vertical ribs grip the wrap around element firmly within the steel retaining ring. CWS SERIES The CWS type is a spacer coupling for shaft to shaft connection. The T-inserts are specially designed for ease of installation and radial removal without disturbing the driver or driven. The CWS series is used for higher power requirements than the SWR series. GR TRASCO - SIT S.p.A. The Trasco GR curved jaw coupling is available in many different configurations.

19 CENTAFLEX A - Centa The A series coupling consists of two steel hubs and a pre-stressed polygon shaped rubber element with metal parts vulcanised. The high quality element, which is extremely flexible in any direction, can be used for almost any purpose. This coupling is available in many styles. Other features and benefits include: Simple, compact, smooth face design. High performance, high speed range. Good shock & vibration absorbing. Requires no maintenance. No axial reaction forces. COUPLINGS CENTAFLEX B - Centa The B series coupling provides an economical flexible shaft coupling transmitting up to 1400Nm torque, a great all round coupling. The element is available in two designs, polyurethane (green) & hytrel (yellow). Other features and benefits include: Compact, light, robust design. Dampens vibrations & shocks. Compensates for axial, radial and angular misalignment. CENTAFLEX H - Centa The H series coupling is a torsionally stiff design that is the perfect solution to problems associated with Diesel-Hydraulic couplings. The hub and flange is the same as the A series Centaflex coupling. Other features and benefits include: High speed. o o Extremely high thermal stability -50 C to +150 C. Oil resistant. CENTAFLEX D & E - Centa The D series is a very reliable, well-proven coupling for generator sets, centrifugal pump sets and other similar drives. This range was designed for diesel driven generator and similar drives, and the wide range of flanges available will allow the coupling to be mounted directly on to most engine flywheels. The D series couplings comprise six design sizes for nominal torques from 250Nm to 20,000Nm. This range will in practice cater for all diesel engines from 3 cylinders upwards to include ratings up to 2,500kW at 1500 RPM. The E series coupling is very similar to the D series but has been designed to be mounted shaft to shaft on electric motor applications. Other features and benefits include: Simple, rubust, safe in operation, compact, fail safe. Damps vibration and shock loads. Accepts axial, angular & radial misalignment. E Series D Series PAGE 17

20 COUPLINGS CONTROL FLEX - Zero-Max The Schmidt Control-Flex coupling was developed to satisfy the higher performance requirements of today's modern power transmission drives. To meet this goal, Schmidt Coupling engineered the unique Control-Flex disc which is based on a parallel linkage system. Unlike elastomeric couplings, the Control-Flex disc allows parallel, angular and axial misalignment, while offering higher torque rigidity and maintaining constant transmission of torque and angular velocity. SCHMIDT L100, L200 & L300 COUPLING - Zero-Max Only the Schmidt offset coupling, which requires a minimum offset, offers so much flexibility in shaft displacement while maintaining undisturbed power transmission at constant angular velocity. The coupling does not add secondary forces to the drive. It also will not transmit radial vibration between the drive and the driven shafts. It is a dynamically clean drive which will help provide a smooth flow of power for maximum product quality, and unlike universal joints, there is no performance loss by increasing shaft offset. Standard Schmidt offset couplings are available for parallel shaft displacement from a minimum of 4 to 440mm and torque capacities from 6.2 to 51,864Nm. Special coupling sizes can be manufactured for any specific customer requirement. The L100 series couplings will handle parallel shaft displacement from a minimum of 4mm to a maximum linear shaft displacement of 77mm with torque ratings from 6.2 to 146.8Nm and shaft speeds up to 4000 RPM. The L100 series is especially suitable for applications in business machines, optical, electronic equipment and robotics. The L200 and L300 series couplings are capable of handling parallel shaft displacement from a minimum of 11mm to a maximum linear shaft displacement of 440mm with torque ratings from 71.9 to 51,864Nm and shaft speeds up to 2500 RPM. The L200 and L300 series are equipped with caged type needle bearings. The shafts are hardened and serve as the inner race of the needle bearings. The coupling can be mounted on shaft hubs or directly to existing flanges. This mounting technique permits installation of the offset coupling without any need to move either of the shafts being coupled. The Schmidt offset coupling has a slight built-in axial freedom to compensate for thermal shaft expansion and assembly tolerances. The maximum angular shaft misalignment should be kept under one-half (%) degree. SCHMIDT L400 COUPLING - Zero-Max Schmidt inline couplings are of the torque-rigid type, designed with two pairs of parallel links installed 90 degrees out of phase with each other. This patented arrangement allows for the precise transmission of torque and constant angular velocity between shafts with relatively large parallel misalignments. The coupling utilizes needle bearings which can be preloaded for "zero" backlash conditions. Typical applications which benefit from the high accuracy provided by Schmidt inline couplings are feeders, embossers, compactors, printing presses and many others. Schmidt inline couplings are available for a torque range from 56 to 2,824Nm. Couplings for higher torque requirements are made available on special order. PAGE 22

21 BEAM - Ruland Flexbeam zero backlash flexible shaft couplings are available with inch and metric bores and outside diameters ranging from 3/8" (6mm) to 1-1/2" (38mm). The Flexbeam series are machined from a single piece of aluminium and feature multiple spiral cuts. Stainless steel is also available. COUPLINGS JAW - Ruland Ruland s zero backlash jaw couplings are three piece couplings comprised of two hubs and an elastic element. The spider, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. Available in two shore hardnesses, these spiders allow the user to customize the jaw coupling's performance. Selecting a soft spider will give the Jawflex the greatest dampening characteristics, while a hard spider will provide the greatest torsional stiffness and strength. All spiders are press fit onto a curved jaw profile, ensuring zero backlash operation. RIGID - Ruland Ruland s rigid couplings are available in one and two piece clamp designs, with and without keyways in steel and stainless steel. Clamp style rigid couplings wrap around the shaft, providing high torsional holding power without the shaft damage and fretting that occurs when a set screw style coupling is used. Two-piece clamp styles also allow for disassembly and maintenance without removal of other machine components and feature opposing hardware for a balanced design. COMPOSITE DISC - Zero-Max The Zero-Max CD coupling is a unique hybrid coupling, combining the best features found in both steel and elastomeric couplings. Through its new open arm disc design and use of rugged composite materials, the coupling offers the high misalignment capacity found in many elastomeric couplings, but with higher torsional stiffness. Compared to steel disc couplings, these couplings offer superior damping and isolation shock and vibrational loads, including elimination of fretting corrosion. Double flex & spacer couplings are also available. Hubs also available in aluminium and stainless steel on indent. PAGE 21

22 COUPLINGS BOLT COUPLING - SIT S.p.A. The bolt coupling is a rigid coupling. It is made of two cast iron halves, which are bolted together. The coupling is maintenance and lubrication free, and its construction prevents fretting corrosion and allows for easy installation and removal. The bolt coupling can be used with or without keyways. BELLOWS - Ruland Belflex bellows couplings are an assembly of two aluminium hubs and a uniform, thin walled stainless steel bellows. The use of aluminium hubs with a bellows results in a coupling with very low inertia, a feature that is very important in today s highly responsive systems. The characteristics of bellows make them an ideal method for transmitting torque in motion control applications. The bellows allow the coupling to bend easily under loads caused by the three basic types of misalignment between shafts (angular, parallel, axial motion). Among servo couplings, bellows type couplings are one of the stiffest available, making them ideal in high performance applications that require a high degree of accuracy and repeatability. OLDHAM - Ruland Oldham couplings are three piece couplings comprised of two aluminium hubs and a center member. The center disc, which is available in a choice of acetal for high torsional stiffness or nylon for vibration and shock absorption, is the torque transmitting element. Torque transmission is accomplished by mating slots in the center disc, located on opposite sides of the disc and oriented 90 degrees apart, with the drive tenons on the hubs. The slots of the disc fit on the tenons of the hub with a slight press fit. This press fit allows the coupling (with an acetal disc) to operate with zero backlash. The coupling can act as a mechanical fuse to protect equipment. DISC - Ruland Discflex is available in single and double disc styles with bore sizes ranging from 1/8" to 1.1/4" in the inch series and 3mm to 30mm in the metric series. The couplings are an assembly of two anodized aluminum hubs, multiple flat stainless steel disc springs and a center spacer for double disc styles. The center spacer is available in a choice of anodized aluminum or insulating acetal for electrical isolation. This results in a high performance motion control coupling with excellent high speed capabilities up to 10,000 rpm, strength and torsional stiffness characteristics, and low inertia for today's highly responsive systems.

23 CONE RING The Cone Ring coupling is very popular. Naismith Engineering stock a full range of Cone Ring couplings in pilot bore and taper bore. Rigid couplings are available on request. Replacement rings are also available. The flexible element consists of tapered rubber rings mounted on steel pins. These rings absorb commonly encountered misalignment, shock and vibration. The flexible rings can be changed by removing the pins from the coupling using simple hand tools, and without the need to disturb the driver or driven machines. COUPLINGS NORMEX The Normex coupling has a very distinctive element that weaves in and out between the jaws. It is very good at taking up misalignment between the driver and driven shafts. The coupling will also help to reduce vibrations and shock loads from the drive. Naismith Engineering stock the element and the hubs to suit TSCHAN-S The Tschan-S coupling is another jaw type coupling that has round legs instead of straight or curved. The Tschan-S is ideally suited to general purpose coupling applications and is capable of reducing shock loads and vibration from drives. The element is made of polyurethane that is resistant to oils and has a temperature range o o from -30 C up to 100 C. Naismith Engineering stock the elements and hubs to suit. HRC The HRC is a very popular coupling, and many people have them in machines today. It is a general purpose coupling using an element in compression. They are easy to install and take up small amounts of misalignment while still reducing the shock loads often found at start up. Naismith Engineering stock a full range of HRC couplings in pilot bore and taper bore. Elements are also available PAGE 25

24 COUPLINGS SERVOFLEX SFC - Miki Pulley ServoClass couplings are specifically designed to meet the precision positioning requirements and high reverse-load characteristics common to many of today's AC and DC servomotor applications. SFC couplings feature zero-backlash flexible metal discs and zero-backlash keyless clamp-type mounting hubs. This high-performance coupling has high torsional stiffness and low inertia to avoid system resonance. It is remarkably flexible as a result of its double-flex-disc design, which provides exceptional misalignment capacity. This flexibility reduces reaction loads, thereby extending the operating life of the connected components while providing smoother system performance. SERVOFLEX SFS - Miki Pulley The SFS ServoClass couplings are also designed to meet the precision positioning requirements and high reverse-load characteristics. With higher torque ratings this coupling suits larger applications. ServoClass couplings feature zero-backlash flexible metal discs. This high-performance coupling has high torsional stiffness and low inertia to avoid system resonance. It is remarkably flexible as a result of its double-flex-disc design, which provides exceptional misalignment capacity. Available in single ( S ), double ( W ) and spacer ( G ) type. TYRE COUPLING The Tyre coupling is primarily designed to allow for misalignment both angular and parallel and compensates for end float. Torsional vibration is reduced and shock loads minimized by the flexing body. The coupling has been successfully subjected, under normal circumstances, to angular misalignment up to 4º, parallel misalignment up to 3mm and end float up to 8mm. The design of the coupling, having a flexing member with remarkable durability, suppresses the initial shock load and eliminates to a marked degree the stresses common to power driven machinery. Tyres available in natural rubber and F.R.A.S. CHAIN COUPLING Roller chain couplings have a torque capacity in excess of the torque normally transmitted by shafting which falls within the coupling bore range. Select the smallest coupling which will accommodate both shafts. For reversing operation, shock or pulsating loads, or other severe operating conditions, select the next larger coupling. A cover should be used to ensure maximum service life, particularly if the coupling operates at high speeds or under moist or abrasive conditions. For proper lubrication, fill the space between the cover and the coupling with soft to medium consistency bearing grease. PAGE 24

25 SCHMIDT L500 COUPLING - Zero-Max Schmidt 5-D couplings were developed to fill a gap in the family of torque-rigid couplings. Most couplings in this family are designed to accommodate either axial, angular, or parallel shaft displacements only. For some applications however, the operational conditions require all possible shaft misalignments. If these shaft misalignments exceed the limit of the selected coupling capacity, excess sideloads are introduced into the equipment which can cause vibrations, life reduction or failure of vital machine components such as bearings, motors, etc. The 5-D couplings, are a modification of the Schmidt inline coupling, designed to accommodate all 5 degrees of shaft displacements. This patented coupling allows easy adjustment to any possible misaligned shaft position without imposing heavy sideloads on shafts, bearings or other machine equipment. Schmidt 5-D couplings offer large shaft misalignment capabilities and constant angular velocity. The acting forces within the coupling can be precisely calculated, ensuring a sound coupling design which is especially important for heavyduty applications. COUPLINGS BAUMANN Standard The principal feature of the Baumann Flex coupling is the multi-layer and multi-coil spring assembly, which is brazed firmly to the end pieces designed either as collars, flanges or hubs. The coupling serves primarily to take up inaccuracies of alignment between two rotating shafts; it provides torsional flexibility in the coupling of such shafts and dampens vibration. Its effectiveness is largely independent of the direction of rotation, as in one direction the outer and middle counter-coiled spring layers work together to transmit the load, while in the other direction, the middle and inner layers come into operation. BAUMANN LM The LM type couplings have a stainless steel spring and two light alloy hubs which are bored the same at each end. Maximum torque can only be achieved with correctly aligned shafts. The maximum shaft misalignment is 8 angular and 2mm parallel. ZG The ZG type coupling comprises a nickel plated steel spring and two cast zinc push-on hubs which are available with metric bores. The maximum shaft misalignment is 5 angular and 1mm parallel. BLS The BLS type coupling is constructed entirely of stainless steel allowing for corrosive environments and ambient temperatures up to 500 C. The maximum shaft misalignment is 1.5 angular and 0.1mm parallel on the size 15 & 3 angular and 0.2mm parallel on the size 23. CHP The CHP type coupling consists of a synthetic rubber bellows and two alloy hubs. The coupling is backlash free and torsionally rigid. The maximum shaft misalignment is 5 angular and 0.25mm parallel. PAGE 23

26 VARIABLE SPEED HI-RATIO - Lovejoy In general, fixed center drives provide a greater total speed ratio than adjustable center drives. Traditional designs offer two pulleys of the same diameter, which means that a large portion of the driven speed range will be above motor speed. For those applications that require wide speed range and low driven speed, this has been a problem. Lovejoy s Hi-Ratio system solves this problem by mating smaller driver and larger driven pulleys to provide the unique combination of broader driven speed ranges and lower minimum driven speeds. Ranges from 0.2kW to 3kW at 1,425 RPM motor speed. HEXADRIVE - Lovejoy Hexadrive pulleys are the most durable variable speed pulleys available. The hexagonshaped center shaft efficiently transmits torque through the six hex flats for top performance and long life. The surface of the shaft is covered with a resilient elastomer, which means there is no metal-to-metal contact on any sliding surface and lubrication is not necessary. These pulleys are available in adjustable or fixed center drives and come in two styles: one-side moveable for V-Flat drives, and two-side moveable for V-V drives. Flanges are made of cast iron to provide a long-wearing belt contact area. These pulleys provide size ranges from 150mm up to 315mm diameter, and a maximum rating of 18kW at 1,425RPM. VAR-Sit The variable speed pulley is a well established drive designed to give continuous speed variation at a comparative low cost. The hub is made from induction hardened steel, hard chrome plated and ground to give uninterrupted slide fit with flanges. Keys are not used with this application. Moving flanges give a wide contact area therefore eliminating uneven belt pressure. The pulley flanges are coupled by means of nylon sleeve couplings to the outside of the flanges and by two flats machined on each end of the pulley hub. Two springs situated inside the nylon coupling give the desired pressure. The pulleys use European standard variable speed belts. There is provision for regreasing the pulley slide ways, although the grease chambers are pre-packed before leaving the factory. STATIONARY ADJUSTABLE PULLEY - Sit Stationary Adjustable Pulleys are designed to allow adjustment of pitch diameters while stationary. They are suitable for M-SPZ,A-SPA,B-SPB,C-SPCsection V-belts. Both one groove and two grooves are constructed in high quality cast iron. One of the flanges has to be screwed on the threaded hub. The movable flange is provided with grub screws for fixing into required position. It is advisable to grease the hub threads periodically. For belt power ratings see our V-belt catalogue. Available in pilot bore and taper bore types. PAGE 28

27 VARIABLE SPEED ECONOLINE SERIES - Lovejoy The Econoline pulley series provides reliable variable speed service with a proven design at an economical cost. Consisting of a wide selection of models, the Econoline series is ideal for both adjustable and fixed center drives using classic A and B section drive belts. This series also offers: driven speed ratios from 1.6 to 1 up to 2.7 to 1 and ranges from 0.25kW to 3kW at 1,425 RPM motor speed. ALUMINOLINE SERIES - Lovejoy Aluminoline variable speed pulleys offer the best possible belt alignment with the least amount of overhung load. Used with A and B drive belts, these pulleys not only have anodized aluminium flanges which provide quiet operation with minimum vibration, but are rated for 0.15kW through 1kW at 1,425 RPM. These two-side moveable pulleys offer greater speed ratios (up to 2.75 to 1). WB SERIES - Lovejoy Pulleys in the WB series use wide variable speed belts for the most efficient transmission of torque through the widest possible speed range. This two-side moveable pulley series offers the best possible belt alignment when used with a grooved companion sheave. WB pulleys provide maximum service when lubricated through a convenient grease fitting and offer sizes ranging from 150mm to 330mm in diameter, with the largest model capable of 9kW at 1,425RPM. All models greater than 0.75kW feature durable cast iron flanges. Models 245 and 260 are made with lightweight, corrosion-resistant anodized aluminium flanges. PAGE 27

28 OVERLOAD PROTECTORS TORQUE TENDER - Zero-Max Torq-Tenders are positive drive couplings which provide accurate overload protection in many mechanical power transmission systems. When a jam-up or excess overload occurs, Torq-Tenders disengage motor drives. Their effective, versatile design, protect your drive train, motor, and entire system. When load exceeds the rating determined by precision tempered torque springs, the unit's drive key pivots out of a slot to disengage the coupling. Once the overload is removed and speed reduced, the Torq-Tender resets itself automatically. All models are available with actuating pins or actuating disc, which will automatically signal an overload warning or shut the machines system down entirely. H-TLC - Zero-Max H-TLC operates on the same basic principle as Torq-Tender, except the torque setting is adjustable and it uses polymer materials in its major components to resist corrosion. If operating conditions require periodic changes in torque settings, the H-TLC gives you that ability. Simply adjust the units external compression bolts until the desired new setting is reached. It works on a series of spring loaded convex pins with detents which react to overloads. Unlike friction-type designs, you can submerge the H-TLC in oil and still depend on precise disengagement at your design limits. PAGE 26

29 DCV - Hi-Lo The DCV series pulleys are adjustable center distance drive type pulleys using standard V-belts. The range is 0.61kW to 4.7kW at 1,425 RPM. They have double pulley face movement to maintain belt alignment on V-drives and contain Hi-Lo's torque sensing mechanism to control belt tension with load requirement. Two face movable design for standard V-belts. Maintains belt alignment between the variable speed pulley and the companion sheave. This is an important feature with close centre distance drives. Models 257 and 265 are an exception however, and should use recommended shaft centre distances. VARIABLE SPEED DCW - Hi-Lo The DCW series pulleys are adjustable centre distance drive type pulleys using variable speed belts. The range is 0.9kW to 18.3kW at 1,425 RPM. They have double pulley face movement to maintain belt alignment on V drives and contain Hi-Lo's torque sensing mechanism to control belt tension with load requirement. Two face movable design for variable speed belts. Maintains belt alignment between the variable speed pulley and the companion sheave. The wider variable speed belts allow a greater speed ratio change than standard V-belts while maintaining a match between the included angle of the pulley faces and the belt. MCV & MCW - Hi-Lo The MCV and MCW series pulleys (manually adjustable) are fixed centre distance drive type pulleys. The MCV pulleys use standard V-belts and have a range of 0.45kW to 3.0kW at 1,425 RPM. The MCW pulleys use variable speed belts and their range is 0.6kW to 4.6kW at 1,425 RPM. HI-RATIO - Hi-Lo Hi-Ratio compound pulley drives provide economy and exceptional efficiency at speed ratios up to 7:1. Pulley faces are made of highly durable plastic containing special additives to insure long service life. The Hi-Ratio pulleys have a range of 0.15kW to 0.3kW at 1,425 RPM. PAGE 31

30 VARIABLE SPEED MODEL AK and PE - Miki Pulley The Model AK and PE employ a wide variable speed belt. They are a nonlubrication type stepless variable speed drive capable of changing drive speed without varying the distance between shafts.

Speed ratios: 1:2 to 1:4) MODEL U - Miki Pulley The Model U is an intermediate wheel type stepless variable-speed drive with standard type V belt. Speed ratio is large and speed can be easily changed with handle. (For motors 0.4 kw to 2.2 kw. Speed ratios: 1:3 to 1:6) TBR - Hi-Lo The TBR series of pulleys are adjustable centre distance drive pulleys using standard V- belts. The range is 0.45kW to 3kW at 1,425 RPM. They have single face movement to provide greater economy on longer centre distance V-drives where absolute belt alignment is not critical. Their through bore construction allows mounting from either end. Hi-Lo's torque sensing mechanism controls belt tension with load requirement One face movable design provides a simplified, economical and trouble free drive system. While belt misalignment is inherent, it is minimal using standard V-belts. The drive should be aligned with the belt at the mean diameter of the variable pulley and the recommended shaft centre distance used as a minimum. PAGE 30

31 MODEL P - Miki Pulley This is a universally used type of pulley. It is usually mounted on a motor shaft, and speed is changed by adjusting the distance between shafts.

(For motors 0.4 kw to 8.5 kw speed ratios to l:3) PAGE 29

32 LOCKING BUSHES TLK110 (self-centering) - Tollok Consists of two conical pieces and a spacer. It has minimum overall dimensions in virtue of the reduced thickness of the cones; so, TLK110 is suitable for the applications where small hubs are used. It is recommended for medium to high torques and is selfcentering. TLK110 guarantees a very precise axial positioning, as no axial displacement of the hub occurs during the assembly operation. Available for shaft diameters from 6 to 130 mm. TLK130 (self-centering) - Tollok Consists of one inside and one outside cone ring, which are joined by a set of screws. It is suitable for high torques and is self-centering. Applications which require a very precise axial positioning are not recommended, owing to a small axial displacement of the hub during the assembly operation. Available for shaft diameters from 18 to 220 mm. TLK131 (self-centering) - Tollok Consists of one inside and one outside cone ring, which are joined by a set of screws. It is suitable for high torques and is self-centering.

33 ZERO-MAX DRIVE Zero-Max drives are mechanical adjustable speed drives. Five sizes provide constant torque of 1.3Nm to 22.5Nm (12 lbs to 200 lbs) throughout the speed range. The speed range is infinitely adjustable from 0 to 1/4 of the input speed under full rated load. This is generally stated as RPM under full rated load assuming an input of 1440 RPM. For lower speed/higher torque applications, some Zero-Max drives are available with in-line or right angle gearheads. They may be connected to any rotating power source up to 2000 RPM. Speed adjustments are easily made by moving a lever control through an arc or turning the handwheel of a screw type control. In either case, precise speed control settings are possible.

34 VARIABLE SPEED VARIABLE SPEED BELT - Lovejoy Lovejoy variable speed belts are designed for long life, even tracking, smooth running, and efficient transmission of power through wide speed ranges. They are made of special synthetic compounds to provide maximum service in conditions where oil, heat o (up to 93 C), and static are present. Maximum recommended belt speed is 5,600 feet per minute. Sizes Available 1422V 2926V 1922V 3230HV 2322V 4430V COMPANION SHEAVE - Lovejoy Lovejoy companion sheaves are made of durable cast iron to ensure best possible wear at the belt contact area. Grooved sheaves, for use with variable speed adjustable centre drives, are machined to match the belt width and angle of standard variable speed belts for optimum efficiency. Flat companion sheaves also available. The spoked design provides strength and light weight. All companion sheaves are precision balanced for smooth running. The sheaves are bored to accept standard QD type tapered bushings for ease of installation, best possible shaft grip and removal from the shaft without damage to any of the parts.

44 LINEAR ACTUATORS CABLE CYLINDER - Tol-O-Matic Introduced over 40 years ago as the first rodless cylinder, the Tol-O-Matic cable cylinder provides reliable linear motion with space and cost-savings features. Its simple yet efficient design, solves a wide variety of application requirements. Unlike rod cylinders, the cable cylinder's stroke is contained within the cylinder itself and that can be a big advantage when space limitations are a consideration. The cable cylinder also allows equal force to be applied in both directions. Cables (fastened to both ends of the piston) pass through gland seals at the ends of the cylinder tube, go around pulleys and are then joined by a load bracket or clevis. The cables can be cut different lengths, threaded through a machine or wrapped around a drum to fill a wide variety of rotary and/or linear motion requirements. First in the industry to offer an automatic tensioning cylinder and combine it with a caliper disc brake for mid-stroke positioning. Tol-O-Matic also offers reed switch options on most cylinder models. BAND CYLINDER - Tol-O-Matic With its introduction of the cable cylinder in 1955, Tol-O-Matic became the first manufacturer to introduce rodless cylinders into the U.S. marketplace. Today, Tol-O-Matic is the largest U.S. manufacturer of cable and band-type cylinders and the only manufacturer to offer all three types of band cylinder BC2 series, BC3 series & BC4 series. All Tol-O-Matic rodless actuators are hardworking, space-saving designs that offer cost-effective automation solutions for unlimited application requirements. The expanded range of BC4 cylinders now go to 2.1/2 bores with thrust up to 540kg. ROD CYLINDER - Tol-O-Matic Tol-O-Matic's full line of prepackaged low-profile rod cylinder slides provides high performance in cost-effective packages. This line covers the broadest offering in the industry providing low cost, with the ability to incorporate several actuators using adaptor plates for X-Y or X-Y-Z applications. Flexible mounting features on each style allow easy integration into new or existing applications. Three different types of rod cylinder slides are available:- RCS, Power-Block, & Power-Block2 ranging from 3/8" to 3.1/4" bore sizes. PAGE 46

45 POSITIONER - Candy Controls The Candy Positioner, POSI series, is a phase shifting mechanism used to accurately adjust and "fine tune" the timing relationship of machine actions. In normal operation, the positioner is a 1:1 phase transmission with input and output shafts rotating in the same direction. When the control shaft is rotated, a differential action occurs between the input and output shafts. This adjustment may occur while the machine is in the static position or while running. By providing "on the fly control", the positioner eliminates costly downtime associated with production set-ups and changeovers. GEARBOXES & TIMING DEVICES CANDY SWITCH - Candy Controls The Candy Switch is used by thousands of equipment manufacturers and users worldwide to control circuits during a machine cycle. This Candy Switch can vary the "on-off" time cycle as well as the length of "on" dwell time. Each electronically controlled machine component can be synchronized to the demands of the parent machine without specifically designed cams or expensive electronic devices. Under average conditions, the Candy Switch mechanism should operate satisfactorily over 100 million cycles at 100 RPM. In most individual applications, it is inherently more accurate than the machine driving it. Adjustable while running. TIMING HUB - Candy Controls The Candy Timing Hub is the low-cost positioner used to positively lock gears, sprockets, cams and levers to shafts while still providing full adjustable timing control. This precision timing hub allows the use of low-cost plate sprockets and hubless gears, and eliminates the cost of machining special slots or clamps often used for timing adjustment. These savings and the low-cost of the hub, clearly show that the Candy Timing Hub is the most economical way to provide positive and accurate positioning control. PHASING HUB - Candy Controls The Phasing Hub is a static phase adjusting coupling designed for precise angular displacements. When in motion, the phasing hub operates as a rigid 1:1 shaft coupling. Phase change of the coupling and connected shafts is accomplished with the drive stopped. By manually turning the adjusting ring, the phasing hub becomes a phase changing device providing infinitely variable and stepless phase correction in either direction. One rotation of the adjusting ring results in 3.6 degrees of adjustment. PAGE 45

48 ROH'LIX - Zero-Max The Roh'lix Linear Actuator is a device that converts rotary motion into linear motion. The Roh'lix uses rolling element ball bearings that trace a helix pattern along the shaft, which produces a Rolling Helix, or Roh'lix for short. Available sizes have thrust capacities ranging from 67 to 889 Newtons and 15 to 200 lbs, shaft diameters ranging from 8mm to 50mm and 3/8 to 2, and leads ranging from 0.625mm to 150mm and to The Roh'lix Linear Actuator consists of six pre-loaded bearings that contact the shaft at an angle. When the shaft is rotated, the bearings trace out an imaginary screw thread, causing the Roh'lix to travel linearly along the shaft. The thrust of the Roh'lix is established by spring force between the two block halves. The thrust force is adjusted by the thrust adjustment screws on the top of the block, allowing the thrust setting to be fine-tuned to individual applications. LINEAR ACTUATORS PAGE 47
