6 Page 04 Coupling election Guide Ø Angular ƒ End float axial 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 Parallel 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. Tyreflex Couplings

Key area A = J x UB length mm (Obtain from relevant catalogue page). 6. Key stress fk = F/A N/mm 2 7. If resultant stress is less than 70 N/mm 2 key stress is acceptable. If resultant fk is greater than 70, consider either two keyways or extending hub length. 8. Example: TK = 7.5 x 9550/1440 = 49.7Nm r = 55/2 = 27.5mm 1000 = m F = 49.7/ = 1741N A = 16 x 45 = 720mm 2 fk = 1741/720 = N/mm2 election is therefore good. For operation above 80% of the declared maximum coupling speed it is recommended that the coupling is dynamically balanced.! WARNING It is the responsibility of the system designer to ensure that the application of the coupling does not endanger the other constituent components in the system. ervice factors given are an initial selection guide.!
