The invention relates to the technical field of ships, in particular to a multi-crank multi-connecting-rod cycloid propeller for ships, which comprises blades, a fixing part, an adjusting part, a driving part and a power gear, the adjusting part comprises an operating rod, a revolution gear, a first revolution bearing, a second revolution bearing, a rotating sleeve, a connecting rod structure and a regulation and control structure, and the revolution gear is meshed with the power gear. The first revolution bearing is connected with the revolution gear and the fixed part; the rotating sleeve comprises a sleeve body, a sleeve plate and a spherical bin, and the connecting structure is hinged to the lower portion of the sleeve plate; the operating rod comprises a pushing end, a mounting end and a ball bearing, the pushing end is connected with the regulation and control structure, and the ball bearing is mounted in the spherical bin; the connecting structure is connected with the mounting end and the blade; and the second revolution bearing is connected with the fixed part and the sleeve body. The spherical hinge bearing is connected with the operating rod, so that an eccentric point can move freely within a certain range on the same plane, loss caused by mechanical friction is reduced, and a complex motion mode of the cycloid propeller is realized.

    本发明涉及船舶技术领域,具体的涉及一种用于船舶的多曲柄多连杆的摆线推进器,包括叶片,固定部,调整部,驱动部,动力齿轮,调整部包括操纵杆、公转齿轮、第一公转轴承、第二公转轴承、旋转套筒、连杆结构、调控结构,公转齿轮与动力齿轮啮合,第一公转轴承与公转齿轮、固定部连接;旋转套筒包括套筒体、套筒板、球形仓,连接结构铰接在套筒板的下方;操纵杆包括推动端、安装端、球轴承,推动端与调控结构连接,球轴承安装在球形仓内;连接结构与安装端、叶片连接;第二公转轴承与固定部连接、套筒体连接。采用球铰轴承连接操纵杆,实现偏心点在同一平面一定范围内任意移动,减少机械摩擦造成的损耗,实现摆线推进器复杂的运动方式。
