Problems solved by technology

[0002] Currently, marine gearboxes in the prior art generally have two structural types: external support and internal support. The driving gear of a traditional external support structure marine gearbox is generally supported on the box by two bearings, resulting in a relatively large axial dimension. Difficult to disassemble and maintain
The traditional internal support structure of the marine gearbox drive gear and clutch seat adopts an integrated structure, the friction plate is relatively small, and the transmission power is limited, an

Abstract

The invention relates to a gearbox, in particular to a gearbox for a lightweight heavy-load ship, and belongs to the field of transmission devices for assisting in power output of ships. The gearbox comprises a box body which is internally provided with an input shaft part, a transmission shaft part and an output shaft part. The input shaft part and the transmission shaft part are engaged for transmission, and the output shaft part is engaged with the input shaft part and the transmission shaft part for transmission. The gearbox for the lightweight heavy-load ship is compact in structure, small in size, low in weight, high in transmission capacity, high in reliability, attractive in appearance, low in manufacturing cost and convenient to assemble, disassemble and repair.

Description

technical field [0001] The invention relates to a gear box, in particular to a lightweight heavy-duty marine gear box, which belongs to the field of transmission devices for auxiliary power output of ships. Background technique [0002] Currently, marine gearboxes in the prior art generally have two structural types: external support and internal support. The driving gear of a traditional external support structure marine gearbox is generally supported on the box by two bearings, resulting in a relatively large axial dimension. Difficult to disassemble and maintain. The traditional internal support structure of the marine gearbox drive gear and clutch seat adopts an integrated structure, the friction plate is relatively small, and the transmission power is limited, and because the drive gear generally needs to be vacantly sleeved on the input shaft or drive shaft through a needle bearing or a sliding bushing In general, the axial force of the gear must be borne by thrust ...
