PIXPowerWare (Dualduty Taper s & ush) PowerWare PIX has always been the innovators and pioneers in the mechanical power transmission and the related products. Innovations, upgradation and providing value added products has always been the passion with PIX. To fulfill its coitment of providing a complete Power Transmission Solution to its users, the company has also added PIXPowerWare s and PIXPowerWare Couplings to its range of V elts. The introduction of PowerWare products in the range would facilitate the users to achieve optimum power transmission from drives consisting of PIXPowerWare with the matched PIX Velt. It will also help users in getting a complete power transmission solution comprising of s, Couplings and elts from the same manufacturer thus eliminating the chances of mismatch. PIXPowerWare s and Couplings are made as per international standards and follow a strict manufacturing procedure in accordance with the ISO standards. This technical catalogue features a technical knowhow about s, ush and Couplings. About s A is also called a sheave or drum and may have a groove between the two flanges around its circumference. The drive element of a system can be a rope, cable, elt, or chain; that runs over the inside the groove. A elt and system is characterised by two or more s in coon to a elt. This allows for mechanical power, torque, and speed to be transmitted across the axles. If the s are of differing diameters, a mechanical advantage is realised. Set screw Integral key A elt drive is analogous to that of a chain drive, however a elt sheave may be smooth (devoid of discrete interlocking members as would be found on a chain sprocket, spur gear, or timing elt) so that the mechanical advantage is approximately given by the ratio of the pitch diameter of the sheaves only, not fixed exactly by the ratio of teeth as with gears and sprockets.

balancing PowerWare Static alancing Concept: When the is statically balanced, then the center of mass lies on the axis of rotation. Crosscheck: Rotate the to any angular position and leave it. If it is statically balanced, then the will retain its position. Procedure: a) You are provided with different masses (in the from of bars) and thus the shaft + masses constitutes your system. b) As of now you assume that the center of mass of the bars is at equidistant from the axis of rotation. m r r m m r m r shaft r r m r m m m r c) Orient the masses on the shaft in such a way that center of mass =? m r = d) or that randomly orient masses m and m (i.e.) and then analytically solve for getting orientation of and (i.e. ). e) anually orient m and m at calculated angles and then see if there is an unbalance, there will be most probably. f) You then need to finely adjust the orientations of any two masses to make the system statically stable. Dynamic balancing: Dynamic balancing is highly recoended in the applications running at high speeds. Concept: The is dynamically balanced, if net moment produced is zero. Crosscheck: When the is dynamically balanced, the system will not undergo vibration, if the is rotated. Procedure: a) ount the elt on the of the shaft b) Current state is that your system is statically balanced (from previous part) c) Considering the bearing near the elt as your origin, you need to come up with the axial position of masses on the shaft a such that: Net moment = a x mr = d) The procedure from this step onwards is analogous to that of Part A from steps e & f, where the lengths of side of polygon is amr instead of mr. To check the unbalance, rotate the at various rpms. OR Dynamic balancing can be calculated using below formula: ½ RP=, / (D), where D is diameter in es and is the face width in es. OR ½ RP=. x, / (D), where D is diameter in and is the face width in. Resultant RP is the maximum recoended operating RP for a sheave or a with a single plane balance (static balancing). Note: if a sheave or is to be operated at higher speed, two plane balancing is recoended.

alignment inspection PowerWare isalignment can either be quantified mathematically, or be compared to some general rules of thumb for quicker and easier results. While using a straight edge to project the plane of the outside face of the sheave or sprocket # with respect to sheave or sprocket #, angular misalignment can be quantified as the difference in clearance between the straight edge and the outside surface of the sheave or sprocket # across the diameter. D isalignment = Tan D The angle of parallel misalignment can be quantified as the difference in clearance between the straight edge and the outer surfaces of the two sheaves or sprockets across the separation distance. D C isalignment = Tan D C The total allowable misalignment recoended for Velts, in general, is /degree. While individual Velts are known to be capable of handling greater amounts of misalignment before becoming unstable, maintaining the misalignment to within /degree will maximize elt life. The total amount of misalignment recoended for synchronous, banded elts and polyv elts is /degree. These drives are less tolerant of misalignment than conventional Velt drives, and must be aligned more accurately. or Velt drives: /degree angle = approximately / per foot of distance traveled. or synchronous, degree angle, and Vribbed drives: /degree angle = approximately / per foot of distance traveled.

PowerWare Couplings

PowerWare PIXTyre Couplings Tyre Couplings are highly elastic, lubrication free, that tolerate large amounts of misalignment in all the planes as well as offers simple installation and inspection without disrupting the drive. Coupling also has excellent shock absorbing properties, while reducing vibration and torsional oscillations. Simple time saving installation motor and machine remains undisturbed whilst tyre is changed, large misalignment capability angular, up to. parallel and. axial Internal load carrying cords are wound in both directions, so there is no problem on reversing drives. Simple visual inspection to aid maintenance Taper and pilot bore flanges ubricationfree PIXTyre coupling ensures high torque transmitting capacity in motor generators & in various industrial machines. The true tyre material is made from neoprene/ natural/synthetic rubber compounds reinforced with Rayon/ Nylon/ Polyester cord to give superior rating & long durability, bore size is well matched to attain maximum speed (rpm) ensuring minimum to nil slippage of the flexible element out from the coupling assembly, in case of any faulty installation. The flexible tyre coupling is a "torsionally elastic" coupling, which minimizes misalignment and maximizes power transmission for optimum machine run time. Key features: acklashfree ow maintenance Torsionally flexible Absorbs misalignment Dampens vibrations and torsional oscillations asy tyre replacement. Highly resilient, flexible tire cushion shock loads, smoothing out the load between driving and driven machines enables high levels of misalignment to be accoodated.. Radially split tyre facilitates easy installation and removal without disturbing the driving or driven shafts.. No maintenance or lubrication is required, visual inspection is all that is necessary.. Taper flanges are made from high grade cast iron and the versatile design enables easy positioning on the shafts. The clamping system prevents relative movement between the flexible tyre and the flange.. Tension member is crosspile, synthetic tension member, which enables torque to be transmitted in either direction.. lastomeric compound available in either natural rubber or fireresistant and antistatic chloroprene, which provides the shape and damping of the tyre.. Taper ush provides a wide range of bore diameters, and enables easy assembly on the shafts.

PowerWare PIXStar / Jaw Couplings PIX Star coupling is a threepieced design which consists of two hubs and an elastomeric element called the spider. Star coupling hubs are machined with high precision, they fit with the spider, assuring zerobacklash operation. The curved star profile is aimed to concentrate the forces to the centre of the spider s limbs, thus providing high effectiveness to the elastomer material. lexible members are provided with proper torsional stiffness to dampen the impulse load, while countering misalignment. PIXSpacer Star Couplings can be used to connect two shafts having larger distances between them. A star coupling is a general purpose power transmission coupling. It is designed to transmit torque (by connecting two shafts) while damping system vibrations and accoodating misalignment, which protects other components from damage. Star couplings consist of three parts: two metallic hubs and an elastomer insert called as an element, but coonly referred to as a "spider". The three parts pressfit together with a star from each hub fitted alternately with the lobes of the spider. The torque here is transmitted through the elastomer lobes in compression. The elastomer of the spider is made of nitrile rubber, which offers good flexibility. Considerations for elastomer selection include ability to dampen the vibrations, handle misalignment, operational temperature range, speed of the equipment, and chemical conditions. Star couplings are considered "failsafe" because, should the elastomer fail or wear away, the Star coupling hub teeth will mate, much like teeth on two gears, and continue to transmit torque. This may or may not be desirable to the user depending on the application. Star couplings elastomers are wearing elements that do need to be inspected and replaced. Star coupling elastomers often have signature wear patterns, and failures can often be root caused based on the condition of the elastomer and hubs. Coon failure causes include misalignment, overtorque, chemical exposure, temperature exposure, torsional vibrations, and hub failure. Key eatures: asy installation: No need of special tools for installation. Accoodates misalignment: compensates for small axial, parallel & angular misalignments. Shock absorbent: lexible member is able to absorb shock loads, and dampen minor vibrations. Spacer couplings available: Can cater shafts at large distances with Spacer Star couplings. Physically robust: Can resist moisture, oils, greases. The flexible rubber element can withstand high temperatures.

The various different hub arrangements, in either (ace), H (Hub), or (finished ore) allows the Taper ush to enter the hub from two different directions. irstly, the bush may enter the hub from inside the coupling ( flange), which allows the coupling hub to be mounted against the bearing on a shaft, reducing overhung loads. Secondly, it is able to enter the hub from outside the coupling (H flange), which assists with ease of installation. Please refer below figures.

PowerWare PIXHRC Couplings Installation HRC Coupling is a semielastomeric coupling and is designed for general purpose applications. It permits quick and easy assembly by means of a taper bush. All outside diameters are fully machined, which allows for a high degree of accuracy via simple alignment methods, such as using a straight edge or the rule method. HRC Couplings are also a failsafe design due to their interacting jaw design & often referred to as a capacity balanced coupling because, if the shaft fits, it will do the job. efore installation, check all components for suitability, particularly where, components previously in service, are being reused. Check taper bushes and the HRC coupling hubs are free of contaminants, lubricants, nicks, burns, and fatigue damage. Any type of contaminant or damage can affect the seating of the taper bush, both on the shaft and in the female bore of the coupling hub (Applicable for Taper ush Coupling Installation). When placing the taper bush into the HRC coupling hub, half holes should be matched to make complete holes. The taper bush should be oriented in order that each complete hole has thread on one side only (Applicable for Taper ush Coupling Installation). efore inserting the screws, ensure all threads are lubricated with oil. The screws should be started, but not tightened, in the threads in the HRC coupling hub (Applicable for Taper ush Coupling Installation). Slide one of the HRC coupling hubs and taper bush assemblies into position. Place the HRC coupling (rubber) element into the other hub and taper bush assembly.

PIXHRC Couplings To ensure correct mating of the two hubs, ensure that couplingassembled, total length is correct. PowerWare ocate the coupling halves and element assembly approximately in the desired position. HRC couplings are required to be mounted with an allowance for a small amount of float. This internal float allows for any linear expansion and maintains the coupling s misalignment capability. To ensure the tapers are seated correctly, it is recoended to tap the front face of the taper bush with a nylon haer or suitable soft drift to ensure no damage occurs to the taper bush. A torque wrench must then be used to achieve the correct tension on the screws as defined in the Table. This procedure should be carried out a number of times to ensure the tapers are correctly seated. After setting the screws to the correct torque, they may require tightening again after tapping with the nylon haer (Applicable for Taper ush Coupling Installation). Table ush size Screw tightening torque (Nm) Screw Details arge end Dia. Approx. mass (Kg) Qty Size (SW) ax Socket size.................................... HRC couplings have a maximum misalignment capability of degree. Correct attention to accurate alignment of the coupling halves is, therefore, essential. any methods of aligning shaft couplings are available, all with varying degrees of resultant accuracy and skills required. aser alignment is the most effective and efficient in achieving accurate alignment (Applicable for Taper ush Coupling Installation). After a period of normal running, it is often prudent to recheck the torque settings on the taper lock bushing screws and retighten as necessary (Applicable for Taper ush Coupling Installation). It is recoended that unfilled holes in the taper bush are filled with grease or silicon sealant to prevent the entrance of contaminants and facilitate future removal requirements (Applicable for Taper ock ush Coupling Installation). After the mounting, affix a safety cover. Touching this product during operation, may cause injury (Applicable for Taper ush Coupling Installation).

Installation Correct Installation of unique pin bush couplings goes a long way in ensuring satisfactory performance. lexible element (rubber bush) is made of rubber reinforced and gives flexibility in all the directions. Normally only rubber bushes & pins may require replacement. Rubber ush must be protected against dripping oil and against the radiation of heat. The bush is fit for ambient temperatures C to + C. ollow below procedure for correct installation of Pin ush Coupling. All components should be cleaned thoroughly, particularly the removal of protective coating in the bore of hubs. The hubs should be bored true to outer diameter and accurately as per shaft sizes. it the hubs, do not haer in hubs if necessary hubs may be heated in oil up to temperature ºC. Hubs should be normally fitted flush with shaft ends. However, shaft can remain inside hubs provided enough length is covered by the hubs.

PowerWare PIXPin ush Couplings The shaft with hubs duly mounted, must be aligned properly. Check the parallel and angular alignment using a dial gauge or straight edge at various locations, to achieve the proper alignment. Necessary shifting/shiing of the equipment may be done. It is advisable to recheck alignment and nut tightness after few hours of initial operation. Retighten the bolts, if necessary. After mounting, affix a safety cover. Touching this product during operation, may cause injury. aintenance Check rubber bushes for wear & tear. If worn out/loose, replace the same. Replace pins, if necessary. The coupling should be shielded according to safety regulations. These shields/guards should be made from wire mesh or perforated sheet, if it is not in contradiction with other & prevailing requirements, in order to ensure adequate ventilation of the coupling.

Installation ount the seals and the hubs, clean all metal parts using nonflaable solvent and check the hubs, shafts and keyways for burrs and remove, if necessary. ightly coat the seals with grease and place well back on the shafts before mounting the hubs. ount the hubs on their respective shafts so that each hub face is flush with the end of the shafts Align the two hubs so that a straight edge rests squarely on both the hubs and also at various intervals

PowerWare PIXResilient / Grid Couplings Pack the gap and all of the grooves in the two hubs with a specified lubricant before mounting the grid. it the grid over the hubs by starting at one cut end, work the coils of the grid tooth by tooth in one direction and seat firmly as you go with a soft mallet. Pack the spaces between and around the grid with as much lubricant as possible and wipe off the excess so that it is flush with the top of the grid. Position the seals on hubs so that it line up with the grooves in the flange. Once the coupling is completely assembled, remove both of the lubrication plugs in the cover and insert a lubrication fitting. Then, pump in the appropriate lubricant, until it is forced out of the opposite lubrication hole & replace the two lubrication plugs. Grid removal Whenever, it is necessary to replace the grid, first remove the cover halves and set aside. eginning at the cut end of the grid, carefully insert a screwdriver into the loop. Using the hub teeth for leverage, gradually pry the grid up, alternating sides while working around the coupling. It is not recoend to reusing the removed grid. After mounting, affix a safety cover. Touching this product during operation, may cause an injury.
