The PTO (Power Take-Off) clutch of a diesel engine is a device used to transmit the engine’s power to external mechanical equipment. It is commonly found in ships, construction machinery, agricultural machinery, and other fields. Its main function is to connect or disconnect the power transmission between the engine and external loads through the clutch, enabling independent control of power output.

Specifically, the PTO clutch is usually installed on the flywheel housing or the output end of the gearbox. Through components such as the flange plate and output shaft, it transmits the engine’s power to external devices like generators, hydraulic pumps, lifting pumps, etc. For example, in marine diesel-electric hybrid propulsion systems, the PTO clutch acts as the primary clutch, allowing the diesel engine to drive the reversible motor and generate electricity independently while the propeller is disengaged, thus enabling power mode switching.

Moreover, the structure of a diesel engine PTO clutch generally includes the flywheel, flywheel housing, short output shaft, flange plate, support seat, and pulley. During use, attention should be paid to the addition and replacement of lubricating oil to ensure normal operation and extend the service life of the clutch.

In summary, the diesel engine PTO clutch is an important component for achieving diversified and flexible power output from the diesel engine. It is widely used in various mechanical systems that require transmitting engine power to external equipment.
