5 The Martin-Flexcoupling is a torsionally elastic coupling offering versatility to designers and engineers with a choice of flange combinations tosuit most flanges are available in either F (face) or H (hub) Taper Bush fitting or bored to the addition of a spacer flange the coupling can be used to accommodate standard distance between shaft ends andfacilitate pump can accommodate simultaneous maximum misalignment in all planes without imposing undue loads onadjacent bearings and the excellent shock-absorbing properties of the flexible tyre reduce vibration and torsional are available in natural rubber compounds for use in ambient temperatures between -50 C and +50 rubber compounds are available for use in adverse operating conditions ( oil or grease contamination) andcan be used in temperatures of -15 C to +70 C.

6 The chloroprene component should also be used when fire-resistance and anti-static ( ) properties are Service FactorDetermine the required Service Factor from table Design PowerMultiply the normal running Power by the service factor. This gives the design Power which is used as a basis for selecting the coupling SizeRefer to Power Ratings table page C-7 and from the appropriate speed read across until a Power greater than that required in step (b) is size of Martin-Flexcoupling required is given at the head of that Bore SizeCheck for Dimensions table page C-9, C-10 that chosen flanges can accommodate required Martin-Flexcoupling is required to transmit50kW from an electric motor which runs at1440 rev/min to a rotary screen for 10 hours perday. The motor shaft is 60mm diameter and thescreen shaft is 55mm diameter.

7 Taper Bush FactorThe appropriate service factor is 1, PowerDesign Power = 50 x 1,3 = SizeBy reading across from 1440 rev/min in the Power ratings table the first Power figure to exceed the required 65kW in step(b) is 75,4kW.
