Fenaflex Couplings Fenaflex couplings provide all the desirable features of an ideal flexible coupling, including Taper-Lock® fixing. The Fenaflex coupling is a "torsionally elastic" coupling offering versatility to designers and engineers with a choice of flange combinations to suit most applications. The flanges are available in either F or H Taper-Lock® fitting or pilot bored, which can be bored to the required size. With the addition of a spacer the coupling can be used to accommodate standard distances between shaft ends and thereby facilitate pump maintenance. Fenaflex couplings can accommodate simultaneous maximum misalignment in all planes without imposing undue loads on adjacent bearings and the excellent shock-absorbing properties of the flexible tyre reduce vibration and torsional oscillations. Fenaflex tyres are available in natural rubber compounds for use in ambient temperatures between –50OC and +50OC. Chloroprene rubber compounds are available for use in adverse operating conditions (e.g. oil or grease contamination) and can be used in temperatures of –15OC to +70OC. The chloroprene compound should also be used when fire-resistance and anti-static (F.R.A.S.) properties are required. SELECTION (a) Service Factor Determine the required Service Factor from table below. (b) Design Power Multiply the normal running power by the service factor. This gives the design power which is used as a basis for selecting the coupling. (c) Coupling Size Refer to Power Ratings table (page 195) and from the appropriate speed read across until a power greater than that required in step (b) is found. The size of Fenaflex coupling required is given at the head of that column. (d) Bore Size Check from Dimensions table (page 196) that chosen flanges can accommodate required bores. R EXAMPLE A Fenaflex coupling is required to transmit 45kW from an A.C. electric motor which runs at 1440 rev/min to a rotary screen for 12 hours per day. The motor shaft is 60mm diameter and the screen shaft is 55mm diameter. Taper Lock is required. (a) Service Factor The appropriate service factor is 1,4. (b) Design Power Design power = 45 x 1,4 = 63kW. (c) Coupling Size By reading across from 1440 rev/min in the power ratings table the first power figure to exceed the required 63kW in step (b) is 75,4kW. The size of coupling is F90 Fenaflex. (d) Bore Size By referring to the dimensions table it can be seen that both shaft diameters fall within the bore range available.

Thanks to special design and machining techniques. All bolts are coated with Dacromet and the nuts are zinc plated which gives an excellent corrosion resistance and makes disassembly possible.M couplings. As a result. By doing so. Escogear couplings of the F and C. Furthermore. all the steel components are protected with a special coating to improve their corrosion resistance. Thanks to this feature the Escogear couplings are ideal for use in presses. the teeth can be designed with a larger section and the root stresses will be reduced. the sleeve will remain perfectly centred on the hub and vibrations will be avoided. This means that for a given torque a smaller coupling can be used which results in more efficient machine design and performance. Thanks to the high precision manufactured. It is clear that this relationship can and will cause problems in coupling selection because misalignment during operation is almost impossible to predict. even after numerous years of service life. portal cranes etc. This specific feature is standard on all F and C. coupling selection is easy and mistakes are avoided: long coupling life is guaranteed. This will reduce the impact loads in start/ stop and reversing torque applications.Escogear ADVANTAGE WHY ESCOGEAR? High torque and misalignment capacity Thanks to the patented Escogear Multicrown profile (used on the C and F series). Due to this clearance.. the Escogear has a torque capacity that is practically independent of the angular misalignment. Furthermore. the Escogear couplings offer the user a very high torque capacity.. The consequence will be higher surface and root stresses and coupling failure might be the result. Therefore. These vibrations will of course influence the operation of the connected equipment. portal cranes). High precision gearing Reduced backlash One of the consequences of the Multicrown design is that the necessary backlash between the teeth can be reduced to an absolute minimum. the optimised coupling design and the standard use of 12. Transparent coupling selection The torque capacity of a gear type coupling strongly depends on the angular misalignment to which it is subjected: the higher the misalignment. this high torque is available at important angular misalignment. In come cases. Esco is able to pilot the top of each hub tooth into the root of the sleeve teeth. . the lower the torque capacity. Drive Couplings 221 DRIVE COUPLINGS Pitch error in the gearing of coupling can strongly affect. the sleeve cannot be perfectly centred on the hubs. a “clearance” between the top of each hub tooth and the root of the sleeve teeth. Excellent protection of components In order to guarantee optimum operation. punching machines. the load distribution between the teeth can be strongly influenced. pitch error is minimized and the best possible gear quality level and life time can be guaranteed.M type are equipped with Esco Multicrown tooth form.. Perfect gear top centring Gear type couplings require. This will create vibrations in applications where the load constantly changes from no load to full load (e. mills.9 quality bolts.g. Thanks to this quite unique design. all Escogear couplings are protected with special surface treatment or coating.. tooth in such a way that the necessary characteristics for homocinetic conjugate tooth action are perfectly achieved. The contact area therefore is larger thus reducing the surface stresses. Less backlash The Esco Multicrown tooth design requires less backlash for a given angle of misalignment than the conventional crowning. 222 Drive Couplings . The tooth contact area under misaligned conditions has a much larger radius of curvature than conventional crowning. thus reducing shocks in reversing application. Constant velocity power transmission Esco generates the Esco Multicrown.Escogear Couplings FLEXIBLE GEAR COUPLINGS SERIES F With ESCO MULTICROWN tooth form for long life Maximum torque: up to 5 040 000 Nm Bore: up to 1 130 mm DRIVE COUPLINGS Lower stresses The Esco Multicrown tooth form is a curve with constantly changing radii of curvature.

Additional special types are available on request. Escogear Couplings SERIES N - C - F HOW TO SELECT THE RIGHT COUPLING SIZE A. Select the size of Escogear coupling that will accommodate the largest shaft diameter. B. Make sure this coupling has the required torque capacity according to following formula: torque in Nm = 9550 x P x Fu n P = power in kW — n = speed in rpm — Fu = service factor according to tabulation 1. The coupling selected (A) must have an equal or greater torque capacity than the result of the formula (B). Otherwise select a larger size coupling. Check if peak torque does not exceed tabulated peak torque Tp indicated in the selection chart. Check also max. allowable misalignment using the graph of tabulation 2. C. Check if shaft/hub connection will transmit the torque. If necessary, select a longer hub.

Tn = nominal torque – Tp = peak torque. 2. Calculate Tn/Tnref and N/Nref and plot the resulting point in the graph. 3. If the resulting point is located in the white area, a standard coupling may be used as far as maximum misalignment doesn’t exceed the maximum misalignment indicated in the graph. 4. If the resulting point is located in the shaded area, refer to Fenner Power Transmission Distributor.

This system furthermore keeps the spacer well centred and works as an anti-fly system through which optimum user safety can be assured.Escodisc Couplings ADVANTAGES WHY ESCODISC? High Torque and Misalignment capacity Thanks to the optimised disc shape and thickness (which could be obtained by infinite element analysis and laser cutting).. the optimised number of bolts and the standard use of 12. DRIVE COUPLINGS Flexible Spacer Design Thanks to the unique design of the Escodisc spacer (flanges bolted to the intermediate tube section – see catalogue drawings DMU/DPU). the standard use of Dacromet protection for the hardware and a special surface treatment. Therefore quick delivery (even for non-standard DBSE) is possible and customer stock can be reduced to a minimum level. This is possible thanks to the use of discs in AISI 301 stainless steel with special surface treatment. the standard use of fillers between the discs to eliminate fretting corrosion and the use of high Safety margin on catalogue values.. Escodisc couplings have been calculated and tested to have no buckling up to the peak torque. This results in trouble free operation. Infinite Life All Escodisc coupligns have been calculated.. mechanical seals.).)... the Escodisc couplins have been designed in suc a way that torque transmissions remains guaranteed for a limited time (through the bolts). (lower or higher temperature level on request).9 quality bolts. Furthermore. its length is easily adaptable to customer requirements. No Buckling In order to guarantee perfect centring of the spacer under all working condition (very important for long DBSE applications) and well controlled stresses in the disc pack. designed and tested for infinite life. Escodisc couplings have a high torque and misalignment capacity combined with reduced reaction forces on connected equipment (bearings. Torque transmission in case of disc pack failure In the unlikely event of a disc pack failure. 244 Drive Couplings . thanks to the use of stainless steel discs. Escodisc couplings are ideal for use in a corrosive environment. Suitable for extreme temperatures and corrosive environment Escodisc couplings can operate at temperatures as high as 270˚C and as low as -40˚C.

Balancing The actual requirement for balancing of a coupling depends amongst other on: – Manufacturing quality of the coupling (Natural Inherent Balance Quality) – Application speed – The mass of the coupling (relative to the masses of the machine rotors) – Distance between shaft ends – Sensitivity of the system Thanks to their high manufacturing quality. Also you can find the maximum limits for high speed/long DBSE applications based on the coupling size. escodisc couplings have a high degree of natural inherent balance and generally don’t require additional balancing for normal speed applications.5 (as specified – Q1 is obtainable yet not advisable for standard couplings) for standard couplings and a component balancing followed by an assembly balancing procedure for high speed applications.
