Problems solved by technology

When the PTO clutch is disengaged, the PTO shaft continues to rotate due to the clutch belt, which cannot meet the needs of the working conditions and also causes unnecessary power loss
On the other hand, the traditional propeller gearbox usually adopts a pressure step-up connection without an accumulator. When another clutch is connected, it will have an impact on the transmission capacity of the working clutch.

Abstract

The present invention discloses a gear case of an adjustable propeller. The gear case is provided with a power output (PTO) device. The PTO device comprises a PTO clutch, a PTO gear, a PTO shaft and a PTO shaft end cover. The present invention is characterized in that the gear case is also provided with a hydraulic brake device; the hydraulic brake device comprises a friction plate holder, an inner and an outer friction plates, a piston, a hydraulic brake casing and an oil distributor. As the hydraulic brake device of the PTO shaft is arranged in the case, the exhaust phenomena in the disengagement process of the PTO clutch is eliminated, and unnecessary power losses caused by gear case exhaust is reduced. The gear case meets the use requirements of users. Besides, the new gear case adopts high pressure connecting and energy storage elements. The gear case is flexibly connected, and the gear case can be provided with a plurality of PTO clutches.

Description

technical field [0001] The invention relates to a power transmission device used on ships, in particular to a gear box with an adjustable propeller. Background technique [0002] The existing adjustable propeller gearbox is often configured with one or more PTO devices, namely auxiliary power output devices: including PTO clutches, PTO gears, PTO shafts, and hydraulic systems. The specific functions of the PTO devices are: when activated In the PTO device, the diesel engine can drive the generator, oil pump, and water pump alone, and can also drive the main propulsion device at the same time—the adjustable propeller works together with the generator, oil pump, and water pump, which makes the output power of the main engine more effective. When the PTO clutch is disengaged, the PTO shaft continues to rotate due to the clutch belt row, which cannot meet the needs of the working conditions, and also causes unnecessary power loss. On the other hand, the traditional propeller ge...
