Selection of a suitable shaft coupling is based upon the following procedure: 1. Select a Service Factor (Fs) according to the APPLICATION and LOAD RAT- ING 2. Determine the equivalent coupling kw rating as follows: Motor kWx100x Fs kW/100rpm RPM of coupling OR 3. Determine the equivalent coupling TORQUE rating as follows: Motor kWxFs T (kNm): Ang. velocity (w) of coupling 4. For motors with starting torque > 2.0 x F.L.T., check equivalent torque. 5. Choose coupling 6. Check that width of coupling 'half' (dimension C) and permissible bore size can be accommodated on the shaft. 7. Check speed of coupling is within permissible RPM. a) The motor used will be restrained using rubber anti-vibration mounts, as such the motor may move slightly upon start-up (due to the inertia in the motor's armature). Select an appropriate coupling to fulfil the design requirements. Explain your choice. b) Calculate: 1. Coupling service factor (Fs) from the table on page marked "page 5.1" on top of the catalogue extract 'DAVID BROWN' supplied. II. Determine the equivalent coupling horsepower rating. c) State appropriate standard flexible coupling by quoting product code (note: check the Bore diameter as part of your coupling selection).

SELECTION Check Shaft Sizes Compare the shaft sizes of driving and driven equipment with the listed maximum bores for the type of coupling required, and note the standard Catalogue Rating for one of adequate bore size to fit the maximum shaft diameter. Compute the Minimum Coupling Rating Required (a) Select a Coupling Service Factor (Fs from the Table page 4. (b) Determine the equivalent Coupling Horsepower Rating as follows:- H.P. per 100 R.P.M.

Load x 7.12 x Fs R.P.M. of Coupling (d) Confirm that a Coupling of minimum suitable bore size for the application has a Catalogue Rating equalling or exceeding the equivalent rating, or else increase the selection to a size that has such rating. Note: Standard Couplings can withstand occasional momentary Peak Loads up to twice their normal rated capacity. This usually caters for starting conditions, etc. Check Maximum Speed The coupling particulars given list the maximum permissible R.P.M. for its material and/or state of balance. Where the application speed exceeds this, refer to our Engineering Department Check Space Limitations The overall dimensions of the Coupling selected should be compared with the space available in the application to see if there is adequate clearance.

The specially developed rubber bushes are free to deform in any direction, substantially reducing noise from severe torque fluctuations and efficiently absorbing vibration. The rubber bushes may be easily and inexpensively replaced without disturbing the coupling assembly. Where couplings are used in conditions causing higher than ambient temperatures or in environments which attack rubber consult Pulleys Australia for recommendations. SELECTION Check Shaft Sizes Compare the shaft sizes of driving and driven equipment with the listed maximum bores for the type of coupling required, and note the standard Catalogue Rating for one of adequate bore size to fit the maximum shaft diameter. Compute the Minimum Coupling Rating Required (a) Select a Coupling Service Factor (Fs from the Table page 4. (b) Determine the equivalent Coupling Horsepower Rating as follows:- H.P. per 100 R.P.M. Actual HP. Load x 100 x Fs R.P.M. of Coupling or alternatively: (c) Determine equivalent Coupling Torque Rating as follows:- Torque (Nm) Actual H.P. Load x 7.12 x Fs R.P.M. of Coupling (d) Confirm that a Coupling of minimum suitable bore size for the application has a Catalogue Rating equalling or exceeding the equivalent rating, or else increase the selection to a size that has such rating. Note: Standard Couplings can withstand occasional momentary Peak Loads up to twice their normal rated capacity. This usually caters for starting conditions, etc. Check Maximum Speed The coupling particulars given list the maximum permissible R.P.M. for its material and/or state of balance. Where the application speed exceeds this, refer to our Engineering Department Check Space Limitations The overall dimensions of the Coupling selected should be compared with the space available in the application to see if there is adequate clearance. Carefully check the shaft extension lengths against coupling bore lengths, the shaft separation distance, and the clearances needed to align or dismantle the coupling If the selected coupling will not fit the space available, refer to our Engineering Dept Selection of a suitable shaft coupling is based upon the following procedure: 1. Select a Service Factor (Fs) according to the APPLICATION and LOAD RAT- ING 2. Determine the equivalent coupling kw rating as follows: Motor kWx100x Fs kW/100rpm RPM of coupling OR 3. Determine the equivalent coupling TORQUE rating as follows: Motor kWxFs T (kNm): Ang. velocity (w) of coupling 4. For motors with starting torque > 2.0 x F.L.T., check equivalent torque. 5. Choose coupling 6. Check that width of coupling 'half' (dimension C) and permissible bore size can be accommodated on the shaft. 7. Check speed of coupling is within permissible RPM. a) The motor used will be restrained using rubber anti-vibration mounts, as such the motor may move slightly upon start-up (due to the inertia in the motor's armature). Select an appropriate coupling to fulfil the design requirements. Explain your choice. b) Calculate: 1. Coupling service factor (Fs) from the table on page marked "page 5.1" on top of the catalogue extract 'DAVID BROWN' supplied. II. Determine the equivalent coupling horsepower rating. c) State appropriate standard flexible coupling by quoting product code (note: check the Bore diameter as part of your coupling selection).
