The invention provides a supporting bearing and a ship propulsion system. The supporting bearing comprises a bearing bush and a self-centering adjusting assembly. The bearing bush is used for being arranged on the outer side of a main shaft in a sleeving mode. The self-centering adjusting assembly comprises a first connecting part, a second connecting part and a switching part; the first connecting part and the second connecting part extend in the circumferential direction relative to the central axis of the bearing bush, and the inner side wall of the first connecting part is connected with the outer side wall of the bearing bush; the switching part is connected between the first connecting part and the second connecting part, and the outer side wall of the second connecting part is used for being connected with a hub of a ship body; and under the condition that the main shaft generates angular displacement relative to the rotating axis, the first connecting part rotates by taking the switching part as a rotating center so as to carry out angle compensation. The edge effect of the supporting bearing can be improved, the local abrasion of the supporting bearing is reduced, and the service life of the bearing bush is prolonged.

    本发明提供一种支承轴承与船舶推进系统,所述支承轴承包括:轴瓦和自对中调整组件;所述轴瓦用于套设于主轴的外侧;所述自对中调整组件包括第一连接部、第二连接部及转接部;所述第一连接部与所述第二连接部相对于所述轴瓦的中轴线沿周向延伸,所述第一连接部的内侧壁与所述轴瓦的外侧壁连接;所述转接部连接于所述第一连接部与所述第二连接部之间,所述第二连接部的外侧壁用于与船体的轴毂连接;在所述主轴相对于旋转轴线发生角位移的情况下,所述第一连接部以所述转接部为旋转中心进行转动,以进行角度补偿。本发明可以改善支承轴承的边缘效应,降低支承轴承的局部磨损,提升轴瓦的使用寿命。
