Gearbox with reversing, ahead running, clutching and full-power PTO (Power Take Off) output functions for ship

Abstract

The invention relates to a gearbox, in particular to a gearbox with reversing, ahead running, clutching and full-power PTO (Power Take Off) output functions for a medium-low power ship. The gearbox comprises an input shaft part which is provided with a first output shaft part fastened together with the input shaft part; the first output shaft part comprises a PTO output shaft, a PTO output shaft coupling, a clutch mechanism, an oil output shaft, an oil path mechanism and a PTO driving gear. By using the gearbox with reversing, ahead running, clutching and full-power PTO (Power Take Off) output functions for the ship, the reversing, the ahead running, stopping and PTO power generation without interference work of the ship can be realized; meanwhile, the PTO output shaft is prevented from penetrating through an inner hole of a driving gear and the shaft can be designed according to the required transmission power, so that the capability of full-power output can be achieved, and further, the requirement for full-power power generation when the ship suspends shipping service is met.

Description

technical field [0001] The invention relates to a gear box, in particular to a medium and small power marine gear box with a reverse car, a clutch function, and a PTO capable of full power output. Background technique [0002] The PTO of medium and small power marine gearboxes in the prior art is generally output from the rear end of the input shaft or transmission shaft. Since the input shaft or transmission shaft needs to pass through the inner hole of the driving gear, the diameter is limited and cannot be enlarged, and the output power is only The rated input power is about 40%. At the same time, the clutch on the input shaft or transmission shaft mainly considers the operation of the propeller, and the PTO does not have a clutch function. Even if the PTO is not working, it can only idle with load. However, the current lighting fishing boat needs the ship to stop sailing when it is operating at sea, and the main engine only needs to have a PTO generator to generate elec...
