SELECTION
Details required for couplings selection
 
1. Type of driven machine and operating hours per day.
    Speed and power absorbed by driven machine (if absorbed power is not known, calculate on power rating of
    prime mover).
3. Diameter of shafts to be connected.
4. Distance between two shaft ends in case of spacer coupling.
  
PROCEDURE
 
a) Service Factor
Determine the required service factor from table.
 
b) 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
Depending upon the type of coupling required, refer to respective power rating table. Power rating can be interpolated in relation to speed parameters.
 
d) Bore Size
Check from the dimension table to see if bore capacity of the coupling is adequate. Otherwise select next higher size coupling.
