The invention discloses a dual-power motor externally-hung marine gearbox which comprises a diesel engine, a motor and a gearbox body, the motor serves as the main power input of the gearbox body, the diesel engine serves as the auxiliary power input of the gearbox body, and the power of the motor is larger than that of the diesel engine; the motor is arranged outside the gearbox, and an output shaft of the motor is in running fit with a motor input shaft in the gearbox through a coupler. The invention provides a dual-power motor externally-hung marine gearbox, and aims to solve the problem that an existing dual-power marine gearbox can only use a diesel engine as main power input or the power of a motor is too small. The high-power motor serves as the main power input of the marine gearbox, silent high-speed traveling is achieved, meanwhile, the diesel engine can be automatically started quickly under the condition that the motor trips, the ship capsizing accident is effectively avoided, and the sailing safety is guaranteed.
本发明公开了一种双动力电机外挂式船用齿轮箱,包括柴油机、电机和齿轮箱,电机作为齿轮箱的主动力输入,柴油机作为齿轮箱的辅助动力输入,电机的功率大于柴油机的功率;电机外置于齿轮箱外部,且电机的输出轴通过联轴器与齿轮箱内部的电机输入轴实现转动配合。本发明提供了一种双动力电机外挂式船用齿轮箱,其目的之一在于,解决现有的双动力船用齿轮箱仅能使用柴油机作为主动力输入或者是电机功率过小的问题,通过大功率电机的外挂式设计,实现大功率电机作为船用齿轮箱的主动力输入,实现静音高速行驶,同时还能够在电机跳闸的情况下快速自启动柴油机,有效避免翻船事故,保障行船的安全性。
