The invention belongs to the technical field of ships, and discloses a double-speed-ratio marine gearbox. The double-speed-ratio marine gearbox comprises a box body, an input shaft system, an output shaft system, a PTO shaft system and a PTH shaft system, wherein the input shaft system, the output shaft system, the PTO shaft system and the PTH shaft system are all arranged in the box body; both the input shaft system and the PTO shaft system can be connected to the diesel engine, the input shaft system is in transmission connection with the output shaft system and the PTH shaft system, the PTO shaft system is in transmission connection with the PTH shaft system, and both the PTH shaft system and the PTO shaft system can be connected to the shaft generator; the input shaft system is provided with an input clutch, the PTO shaft system is provided with a PTO clutch, and the PTH shaft system is provided with a PTH clutch. Switching of two speed ratios is achieved through engagement and disengagement of the clutches, so that the speed ratios of different gears can be replaced without shutdown, and the size is reduced.

    本发明属于船舶技术领域,公开了一种双速比船用齿轮箱。该双速比船用齿轮箱包括箱体、输入轴系、输出轴系、PTO轴系和PTH轴系,输入轴系、输出轴系、PTO轴系和PTH轴系均设置于箱体内;输入轴系和PTO轴系均能连接于柴油机,输入轴系分别传动连接于输出轴系和PTH轴系,PTO轴系与PTH轴系传动连接,PTH轴系和PTO轴系均能连接于轴带发电机;输入轴系设有输入离合器,PTO轴系设有PTO离合器,PTH轴系设有PTH离合器。通过各个离合器的合排和脱排来实现两种速比的切换,从而实现不停机即可更换不同档位的速比,且缩小了体积。
