The invention relates to the technical field of ship propulsion, and discloses a still water balance type thrust bearing, a ship propulsion system and an underwater vehicle. The thrust bearing comprises a mounting seat, a first thrust pad assembly, a second thrust pad assembly and a piston cylinder assembly, the first radial bearing seat is arranged at the bow end of the mounting seat, and the second radial bearing seat is arranged at the stern end of the mounting seat; the first thrust pad assembly, the second thrust pad assembly and at least part of the piston cylinder assembly are arranged in the accommodating cavity of the mounting seat; the piston cylinder assembly is connected with the bow end, and a compression cavity of the piston cylinder assembly is communicated with an external water environment; the first thrust pad assembly is clamped between the thrust disc and the piston cylinder assembly, and the second thrust pad assembly is clamped between the thrust disc and the stern end. According to the thrust bearing, hydrostatic pressure borne by the two ends of the thrust bearing is balanced, so that the thrust bearing only transmits thrust, the constraint of the navigation depth on the thrust bearing design is relieved, the size and weight of the thrust bearing are reduced, and the thrust bearing can be conveniently arranged in the underwater vehicle.

    本发明涉及船舶推进技术领域,公开了一种静水平衡式推力轴承、船舶推进系统及水下航行器。上述推力轴承包括安装座、第一推力瓦组件、第二推力瓦组件和活塞缸组件;第一径向轴承座设于安装座的艏端,第二径向轴承座设于安装座的艉端;第一推力瓦组件、第二推力瓦组件和至少部分活塞缸组件设于安装座的容纳腔;活塞缸组件与艏端连接,活塞缸组件的压缩腔用于外界水体环境连通;第一推力瓦组件夹设于推力盘和活塞缸组件之间,第二推力瓦组件夹设于推力盘和艉端之间。本发明通过平衡推力轴承两端所受静水压力,使得推力轴承仅传递推力,解除航行深度对推力轴承设计的约束,由此减小推力轴承的体积和重量,便于推力轴承布置在水下航行器内。
