The invention relates to a marine gearbox. The invention discloses a gearbox for an oil-electricity hybrid power ship. An oil way control system comprises a motor-level oil way and a fuel-level oil way. A directional oil pump is arranged on the motor-level oil way; two hydraulic control normally-closed two-position three-way valves are arranged at the oil outlet end of the direction oil pump, and the on-off of the hydraulic control normally-closed two-position three-way valves is controlled through a fuel level feedback oil way. Hydraulic control normally-closed switches are arranged on working oil ways of a fuel-level reversing clutch and an ahead running clutch respectively, and on-off of the hydraulic control normally-closed switches is controlled through a motor-level feedback oil way at the oil outlet end of a motor-level direction oil pump. The invention provides a gearbox for an oil-electricity hybrid power ship, which is compact and simple in structure, reliable in work, soft in connection and arrangement and good in part universality, and cannot cause mechanical faults due to wrong directions. The problem that in the prior art, the rotating direction of a motor is matched with the working direction of a diesel engine side clutch, and mismatching is prone to occurring is solved.
本发明涉及一种船用齿轮箱。一种油电混合动力船用齿轮箱,油路控制系统包括电机级油路和燃油级油路;在电机级油路上设置方向油泵;在方向油泵出油端分设两个液控常闭式2位3通阀,通过燃油级反馈油路控制液控常闭式2位3通阀的通断;在燃油级倒车离合器和顺车离合器工作油路上各设1个液控常闭式开关,通过电机级方向油泵出油端的电机级反馈油路控制其通断。本发明提供了一种结构紧凑,结构简单、不会因错向而引起机械故障工作可靠、接排柔和、零件通用性好的一种油电混合动力船用齿轮箱;解决了现有技术中存在的电机旋转方向与柴油机侧离合器工作方向匹配容易出现错向不匹配问题。
