Abstract

The invention is applicable to the technical field of gearboxes and provides a half-slip clutch gearbox. An input shaft, a first middle shaft and a second middle shaft which are in transmission connection with each other are arranged. One end of the first middle shaft is connected with a first shell gear through a half-slip clutch. One end of the input shaft is connected with a second shell gear through a first clutch. The second shell gear is also fixedly connected with an output shaft. One end of the second middle shaft is fixedly connected with a third shell gear through a second clutch. Besides, the first shell gear, the second shell gear and the third shell gear mesh with each other and thus can be in transmission through multiple routes respectively. According to the half-slip clutchgearbox, the problems of a large amount of heat dissipation and poor manipulability brought by use of extra-large specification slip clutch are solved; by adopting mutually-independent transmission routes, the systematic safety redundancy degree is improved; and even though one transmission route fails, it can still be guaranteed that the system continues working.

Description

technical field [0001] The invention belongs to the technical field of gear boxes, and in particular relates to a gear box with a half-slip differential clutch. Background technique [0002] Currently on the market, compared with controllable pitch propeller azimuth propulsion systems, fixed pitch propeller azimuth has the advantages of high reliability, high efficiency, and low cost, but its maneuverability is not as good as controllable pitch propeller. [0003] On the one hand, the azimuth propulsion system with a medium and high-speed diesel engine as the prime mover cannot work below the idling speed of the diesel engine, which makes it impossible for the fixed-pitch propeller to operate at a low speed, thus limiting the low-speed navigation conditions of the ship. The usual solution is to use a semi-slip clutch to realize continuously variable transmission in order to obtain extremely low output speed. At present, the maximum transmission power of foreign semi-slip cl...
