13 Page 11 Coupling election Guide Ø Angular End float ƒ Ø O Parallel offset Torsional flexibility Flexible Couplings should be used to accommodate any combination of misalignment conditions described below. At installation all couplings should be aligned as near to perfect as possible. 1. Angular Angular misalignment is present when the shaft axes are inclined one to the other. Its magnitude can be measured at the coupling faces. 2. Parallel Offset Axial misalignment is present when the axes of the driving and driven shafts are parallel but laterally displaced. 3. End float (axial) End float is the ability to accommodate a relative axial displacement of the connected shafts; achieved by sliding members or flexing of resilient components. 4. Torsional flexibility Torsional flexibility is a design feature necessary to permit shock and impulsive loadings to be suitably dampened. It is achieved by the provision of a flexible medium such as rubber, springs, etc., between the two halves of the coupling. election In order to select the correct type and size of coupling, the following basic information should be known: Power to be transmitted (a) Normal. (b) aximum. (c) Whether continuous or intermittent. Characteristics of the drive (a) Type of prime mover and associated equipment. (b) Degree of impulsiveness of driven load. peed in revolutions per minute (a) At which normal power is transmitted. (b) At which maximum power is transmitted. (c) aximum speed. Dimensions of shafts to be connected (a) Actual diameter. (b) Length of shaft extension. (c) Full keyway particulars. election When the input drive is not steady (i.e. not from an electric motor), and/or the driven load is impulsive, the actual power is multiplied by a ervice Factor from the Table 2 (page 13). election Procedure 1. Nominal power in kw to be transmitted = K. 2. elect appropriate load classification from Table 1, denoted as either, or. 3. From Table 2, establish ervice Factor(s) to be applied, taking into account hours of operation/day and prime mover = fd. 4. From Table 3 select factor for the required frequency of starts/hr = f. 5. election Power Ks = K x fd x f 6. Equivalent power at 100 RP = Ks x 100 RP 7. Check that coupling selected will accept the required shaft diameters. hould shaft diameter exceed maximum permissible, then re-select using next larger size of coupling.

55 Page 53 Renoldflex A torsionally stiff, backlash free coupling with misalignment capacity. Designed for use at high speeds and in high temperatures. Torsionally rigid steel coupling Renoldflex is a range of couplings that utilizes a stainless spring steel disc pack to provide a positive backlash free drive. The coupling consists of two carbon steel hubs that are connected to the disc packs with a system of micrometric precision bushings and high tensile steel screws. This construction provides a backlash free and torsionally rigid drive with the additional benefit of a 100% steel construction. The Renoldflex range of couplings is based upon a modular component assembly; therefore it can be easily adapted to suit a wide variety of applications and design situations: The Renoldflex type A uses a single disc pack and two hubs. It permits both axial and angular misalignments. This arrangement guarantees the highest torsional stiffness for this range of couplings. A special vertical support can be produced to allow for vertical or inclined mounting of the type A arrangement. The Renoldflex type B uses two disc packs, two hubs and a spacer. It permits axial, angular and radial misalignments. The spacer component can be supplied in several lengths to allow for different axial dimensions. Coupling capacity aximum 100rpm: 482kW aximum torque: 46000Nm (Using TT flexible elements) Features and benefits Torsionally stiff ideal for use on precision machines 100% maintenance free long life with little wear isalignment capabilities allowing flexibility in installation Zero backlash guarantees operational accuracy igh operating temperatures, suitable for harsh operating environments and temperatures up to 240ºC Taper bored and cone clamp hubs also available igh transmissible torque (TT) flexible elements available from size 70 up igh operating speeds tandard range comprises haft to haft pacer type Can be certified for use in potentially explosive atmospheres containing gas or dust, according to ATEX directive 94/9/EC.

[%] Axial misalignment Working temperature [ fig 02 ] isalignment diagram [ fig 03 ] isalignment factor f 1 [ fig 04 ] Temperature factor f 2 Renoldflex coupling size selection In order to select the most suitable sized coupling, a number of service factors must be taken into consideration. These service factors make adjustments to the design torque (T) of an application to take into account factors such as misalignment, load classification, driver classification as well as high ambient temperatures to produce a selection torque (T, where T = T x f ). The most suitable coupling is then selected by comparing the selection torque (T ) and the couplings nominal torque (T N ). Please note it is important to ensure that the coupling selected will accept the required shaft diameters. hould shaft diameter exceed the maximum permissible then a larger coupling should be selected. The total service factor f = f 1 x f 2 x f 3 ; where f1 is the misalignment factor, f 2 is the load classification factor and f 3 is the temperature factor. Note; the load classification factor is weighted depending upon the prime mover classification. These service factors are defined below: isalignment factor f 1 The maximum misalignments quoted within the technical data for the Renoldflex coupling range cannot be present at the same time. Therefore, the presence of any axial misalignment ax reduces the possibility for offset misalignment rad and angular misalignment ang, which can be seen in [ fig 02 ]. The combined total angular misalignment TOT is a function of the angular misalignment ang and offset misalignment rad of the shafts, according to the following formula: TOT [ ]= ang + arctan rad 2 (-B) The values and B [mm] are given in the overall dimensions table. The misalignment factor f 1 is a function of TOT as shown in [ fig 03 ]. Load factor f 2 The following load factors apply for machines operated by electric or hydraulic motors as well as steam or gas turbines. load factor OPERATING ACINE f 2 Blowers: low inertia 1.1 Blowers: high inertia, cooling towers 2.0 Centrifugal pumps: low inertia and light liquids 1.1 Centrifugal pumps: high inertia or semi-liquid materials 1.75 Conveyors 1.5 Elevators and cranes 2.0 Gear pumps 1.5 achine tools: auxiliary drives 1.1 achine tools: main drives 1.75 ills 2.5 Paper machines and textile machines 2.0 Presses 3.0 Reciprocating pumps 2.5 Woodworking machines 1.5 For machines operated by alternative prime movers the load factor f 2 must be adjusted as follows: f 2 +1 for machines operated by IC engines with 4 or 5 pistons. f for machines operated by IC engines with 6 pistons, hydraulic turbines or with a start torque >2. The following must be taken into account with regard to repetitive high peak torque applications: For non reversing duty: T> Peak torque For reversing duty: T> 1.5 Peak torque. Temperature factor f 3 Renoldflex couplings are unaffected by temperatures up to 160 C. For applications with higher temperatures, the temperature factor f 3 seen in [ fig 04 ] must be taken into consideration. Resilient and oft tart Couplings

61 Page 59 Operating Principles OUTER Outer COVER covers DRIVING IPELLER (A) Driving (OR PUP) impeller (A) (or pump) DRIVEN Driven IPELLER impeller (B) (B) (OR TURBINE) (or turbine) INPUT Input OUTPUT Output [ fig 07 ] The coupling is partially filled with hydraulic oil to a level suitable for the absorbed power of the application and the acceleration characteristics of the driven machinery. The optimum oil fill is that which just allows the driven machine to accelerate from rest, thus providing the best drive overload protection. Power is supplied to the input side of the coupling by either an electric motor or diesel engine. This causes the driving impeller (A) [ fig 07 ] to be rotated at motor speed, oil is thrown outwards by centrifugal force. The flow of oil is directed across the blades of the impeller towards the opposing turbine (B). Kinetic energy is absorbed by the turbine and translated into torque, which is always equal to the input torque and produces rotation of the output member (in the same direction as the driver). All hydraulic couplings can be driven in either directions of rotation. The input and output positions shown are standard, but the input can be from either side of the coupling. The standard drive arrangement allows the outer cover to be rotated whilst at rest to facilitate oil filling. owever, if a brake drum or disc brake is fitted, the brake should be at the coupling output. ee page 67. To calculate slip % (Input speed - output speed) x 100 Input speed The low resistance of the impeller at start up allows the motor to quickly accelerate to full speed. The driven load accelerates smoothly to within a small percentage of the motor speed. This speed difference is referred to as slip and must always be present for the successful operation of a fluid coupling. Typical values of slip will vary between 2% (large power) and 6% (small power).

62 Page 60 Delayed Fill [ fig 08 ] [ fig 09 ] [ fig 10 ] ydrastart Delayed Fill Chamber (Type...R) ydratart (constant fill) hydraulic couplings having a maximum oil fill will limit the starting torque to approximately 200% of nominal torque. It is possible to reduce this figure by reducing the quantity of oil in the circuit. The disadvantage of this method is that it produces increased slip and higher operating temperatures. To overcome these problems a delay fill chamber is available on sizes 8 and above. This chamber is a modular option and allows a calibrated oil feed into the working circuit. In this way, starting torque can be reduced whilst minimising slip under normal running. At rest [ fig 08 ] With the drive at rest, oil drains from the working circuit into the delay chamber. Accelerating [ fig 09 ] At start up the coupling will transmit limited torque, allowing the motor to reach rated speed quickly. Oil flows from the chamber to the working circuit proportionally to the speed. Running [ fig 10 ] When the coupling achieves its rated speed, almost all of the oil is in the working circuit and the torque is transmitted at the minimum slip value.! CAUTION The outer case of the ydrastart coupling can become hot during operation. Do not touch the coupling or a burn may result.! CAUTION Do not attempt to change the coupling oil during or soon after operation has ceased, as the oil may be hot and could cause burns. Resilient and oft tart Couplings

At start up all the motor torque is available to accelerate the motor rotor and coupling impeller (pump). The driven impeller (turbine) increases speed smoothly from zero rpm until the 100% slip curve intersects the motor torque curve at approximately 85% motor speed [ fig 13 ]. When the torque developed by the ydratart coupling matches the resisting torque of the driven machine, acceleration of the load commences and continues up to running speed which will be between 94% and 98% of the driving speed depending on the coupling size. ydratart couplings fitted on diesel engines ydratart fluid couplings can be used with all types of industrial machinery driven by internal combustion engines. [ fig 14 ] shows typical engine and coupling performance curves. The horizontal curve represents the engine s torque curve whilst the vertical shows the torque capacity of the coupling for different slip values and speeds. As load on the driven shaft increases it demands torque, causing the coupling to slip at higher level. If still greater loads are demanded then the coupling will eventually slip at 100%. Note this does not happen until the engine has developed peak torque. [ fig Input speed % Thus by using a fluid coupling, it permits an engine to develop maximum torque without stalling under load and promotes rapid acceleration to normal load speed.

67 Page 65 Overload Protection L L When a hydraulic coupling experiences overload there is a correspondingly high slip value accompanied by a rise in the oil temperature. To prevent damage to the drive there are three options available. 1. Fusible plug This is fitted as standard on all ydratart couplings sizes 4 and above. The standard plug is set to fuse at 138 C. Another option available allows fusing at 183 C. Because oil is discharged when the plug fuses it is advisable to correctly guard couplings using this type of device. 2. Thermal trigger Fitted as an option on ydratart couplings sizes 6 and above, this device prevents oil being discharged from the coupling at overload. As with the fusible plug, two melt temperatures are offered. When melt point is reached a pin is released which engages with a limit switch. The signal from this switch can operate an alarm or switch off the electric motor to protect the drive. After the cause of the overload has been removed the drive can be restarted after replacing the thermal trigger. ydratart thermal trigger ize A L Li Operating principles This device will trigger the limit switch if the oil temperature reaches a predetermined level without loss of oil from the coupling.
