Summary
Selection of KC Coupling
Selection of KC Coupling
1. Operating Conditions
A) Operating hours/day
B) Types of load and prime mover
C) Transmission power (kW) and speed (rpm) of coupling
D) Diameters of both shafts
2. Selection Method
A) Find service factor from the Service Factor Table according to
operating conditions a) and b).
B) Determine the compensated chain drive power (kW) by multiplying
the transmission power kW by the service factor above.
C) Find a proper coupling, which meets the compensated chain drive
power, from the Chain Power Transmission Table below according
to the operating speed of the coupling.
D) If the maximum allowable shaft diameter specified for the selected
coupling is smaller than the actual shaft diameter, reselect the
larger coupling with proper allowable shaft diameter.
E) When using standard key at a low speed, the pressure acting on the
key surface will be increased excessively in some cases. Therefore,
it is required to calculate the pressure acting on the key surface to
find whether the use of special key or spline is necessary.
