A coupling is a machine element that connects the shaft from a driving component, such as a motor, to the shaft of a driven component, such as a propeller, a pump, or a gearbox.
The functions of a coupling is to:
- transmit rotational motion or torque from one shaft to the other,
- compensate for misalignment between the two shafts,
- absorb vibration from one shaft and prevent it from being transmitted to the other,
- absorb heat from one shaft and prevent it from being transmitted to the other,
- isolate electricity and prevent it from being transmitted from one shaft to the other.
