Marine gearbox in special arrangement form

The invention discloses a marine gearbox in a special arrangement form, and relates to the field of gearboxes. The marine gearbox comprises a box body, wherein an output shaft, a reversing transmission shaft and an input shaft are arranged in the box body, the output shaft is arranged above the input shaft to form vertical heterocentric output, and connecting lines among axes of an output shaft, a reversing transmission shaft and an input shaft of the gearbox form a triangle. The marine gearbox has the beneficial effects that the requirement for lower input and upper output can be met, and the gearbox is provided with a stable hydraulic oil supply system and works normally. The output rotating speed of the output shaft of the gearbox is lower due to slip frequency when the diesel engine is idling. The market demand of rapid development at present is met, and the blank of corresponding domestic fields is filled. 本发明公开了一种特种布置形式的船用齿轮箱，涉及齿轮箱领域，包括箱体，箱体内设有输出轴、倒车传动轴和输入轴，且输出轴布置在输入轴的上方，形成垂直异中心输出，齿轮箱的输出轴、倒车传动轴和输入轴三者轴心之
