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 O Ø 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 ƒ 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.

(b) Maximum. (c) Whether continuous or intermittent. Characteristics of the drive (a) Type of prime mover and associated equipment. (b) Degree of impulsiveness of driven load. Speed in revolutions per minute (a) At which normal power is transmitted. (b) At which maximum power is transmitted. (c) Maximum speed. Dimensions of shafts to be connected (a) Actual diameter. (b) Length of shaft extension. (c) Full keyway particulars. Selection 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 Service Factor from the Table 2 (page 13). Selection Procedure 1. Nominal power in kW to be transmitted = K. 2. Select appropriate load classification from Table 1, denoted as either S, M or H. 3. From Table 2, establish Service 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 = fS. 5. Selection Power Ks = K x fD x fS 6. Equivalent power at 100 RPM = Ks x 100 RPM 7. Check that coupling selected will accept the required shaft diameters. Should shaft diameter exceed maximum permissible, then re-select using next larger size of coupling.
