The invention belongs to the technical field of ships, and discloses a medium-high speed double-propeller ship. The medium-high-speed double-propeller ship comprises a ship body, two propelling devices and two shaft supporting assemblies. Two bumps which are symmetrically arranged along the central axis in the width direction of the ship body are arranged at the bottom of the stern of the ship body; the two propelling devices are symmetrically arranged along the central axis of the width direction of the ship body and correspond to the two bumps one to one, each propelling device comprises a main engine, a gear box, a propelling shaft and a propeller, the main engines are arranged in the ship body, the gear boxes are arranged in the bumps and connected with the main engines, one end of each propelling shaft is connected to the corresponding gear box, and the other end of each propelling shaft is connected to the corresponding propeller. The other end penetrates through the bump and is connected to the propeller; each propeller shaft is provided with a shaft supporting assembly, one end of each shaft supporting assembly is connected to the corresponding propeller shaft, and the other end of each shaft supporting assembly is connected to the ship body to support the corresponding propeller shaft. The medium-high-speed twin-propeller ship can reduce resistance and improve the propelling efficiency, meanwhile, the wake flow is good, the cavitation performance of the propellers can be improved, and pulsating pressure generated by the propellers on the ship body is reduced.

    本发明属于船舶技术领域,公开了一种中高速双桨船。中高速双桨船包括船体、两个推进装置和两个轴支撑组件。船体的船尾的底部设有两个沿船体的宽度方向的中心轴线对称设置的鼓包;两个推进装置沿船体的宽度方向的中心轴线对称设置并与两个鼓包一一对应设置,推进装置包括主机、齿轮箱、推进轴和螺旋桨,主机设置于船体内,齿轮箱设置于鼓包内并与主机连接,推进轴的一端连接于齿轮箱,另一端穿设于鼓包并连接于螺旋桨;每个推进轴均设有轴支撑组件,轴支撑组件的一端连接于推进轴,另一端连接于船体,以支撑推进轴。该中高速双桨船能够降低阻力,提高推进效率,同时伴流较好,有助于改善螺旋桨空泡性能,降低螺旋桨对船体产生的脉动压力。
