1) Description of Shaft Coupling
A shaft coupling is a mechanical component that connects the drive shaft and driven shaft of a motor, etc.,
in order to transmit power. Shaft couplings introduce mechanical flexibility, providing tolerance for shaft misalignment.
2) Applications of Shaft Coupling
The shaft coupling is mechanical components that connect two rotating shafts, such as the driving shaft
and the driven shaft, for the purpose of transmitting power. It is used in motors, pumps, generators,
and compressors.
