DRIVE COUPLINGS Table 3-1 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 For 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 -50°C and +50°C, Chloroprene rubber compounds are available for use in adverse operating conditions le.g. oil or grease contamination) and can be used in temperatures of -15°C to +70°C. 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. 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 Fenaflex coupling service factor" Refer to Power Ratings table (page 125) and from the appropriate speed read across until a power greater than that required in step It is found. The size of Fenaflex coupling required is given at the head of that column (d) Bore Size Check from Dimensions table (page 126) that chosen flanges can accommodate required bores. EXAMPLE A Fenaflex coupling is required to transmit 45kW from an A.C. electric motor which runs at 1440 rewmin to a rotary screen for 12 hours per day. The motor shaft is 60mm diameter and the screen shaft is 65mm 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 (e) Coupling Size By reading across from 1440 r/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 bare range available.
