product Overview

Domestic marine gearbox research and development institutions, etc. cooperate to develop various marine gearboxes

The marine gearbox has the functions of reversing, clutching, decelerating and withstanding the thrust of the propeller, and is matched with the main engine to form a marine power unit.
The "transmission capacity" in the manual refers to the ratio of the continuous power of the engine to the rated speed, and the deceleration ratio and transmission capacity correspond up and down.
The selection should be less than the value in the manual.
Rigid connections are not allowed in the gearbox and engine shaft system, and the brackets are recommended for mounting on the same rigid support. If the engine is installed
Elastic support, while the gearbox is mounted on rigid support. You should contact the company's technical department to select a suitable highly elastic coupling.
Some of the hosts listed are for reference only, as they may not be applicable for a certain reduction ratio.
Weight is approximate, and the weight varies depending on the reduction ratio.
After a certain period of time, the gearbox may be improved to varying degrees, subject to the technical parameters provided at the time of contract signing.
