Details About Coupling

Where the shaft speed of a medium-speed diesel is not suitable for its application, e.g. where a low-speed drive for a propeller is required, a gearbox must be provided. Between the engine and gearbox, it is usual to fit some form of flexible coupling to dampen out vibrations. There is also often a need for a clutch to disconnect the engine from the gearbox.

Must Read: Information About Clutches

Elastic or flexible couplings allow slight misalignment and damp out or remove torque variations from the engine. The coupling may in addition function as a clutch or disconnecting device. Couplings may be mechanical, electrical, hydraulic or pneumatic in operation. It is usual to combine the function of a clutch with a coupling and this is not readily possible with the mechanical coupling.
