The invention relates to the technical field of ship propulsion systems, and provides a stern bearing for a ship propulsion shafting, a ship propulsion system and a ship, the stern bearing for the ship propulsion shafting comprises a bearing outer bushing, a bearing inner bushing and a roller; a first arc-shaped groove is concavely formed in the inner side wall of the bearing outer bushing and extends in the circumferential direction of the bearing outer bushing; the bearing inner bushing is arranged in the bearing outer bushing; a second arc-shaped groove is concavely formed in the outer side wall of the bearing neck bush, the second arc-shaped groove extends in the circumferential direction of the bearing neck bush, and the second arc-shaped groove and the first arc-shaped groove are oppositely formed; the bearing neck bush is used for being arranged on the main shaft in a sleeving mode, and the axis of the bearing neck bush coincides with the axis of the main shaft. The pin rollers are movably arranged between the bearing outer bushing and the bearing inner bushing in the axial direction of the bearing outer bushing, and the outer side walls of the pin rollers are attached to the first arc-shaped grooves and the second arc-shaped grooves correspondingly; inclination or axial movement of the main shaft is compensated through sliding of the pin rollers, and the abnormal abrasion phenomenon is reduced.
本发明涉及船舶推进系统技术领域,提供一种用于船舶推进轴系的艉轴承、船舶推进系统及船舶,所述用于船舶推进轴系的艉轴承包括:轴承外衬套、轴承内衬套及滚柱;轴承外衬套的内侧壁凹设有第一弧形槽,第一弧形槽沿轴承外衬套的周向延伸;轴承内衬套设于轴承外衬套内;轴承内衬套的外侧壁凹设有第二弧形槽,第二弧形槽沿轴承内衬套的周向延伸,第二弧形槽与第一弧形槽呈相对设置;轴承内衬套用于套设于主轴上,轴承内衬套的轴线与主轴的轴线重合;滚柱沿轴承外衬套的轴向方向可移动地设于轴承外衬套与轴承内衬套之间,滚柱的外侧壁分别与第一弧形槽及第二弧形槽贴合;本发明通过滚柱的滑动以补偿主轴的倾斜或轴向窜动,减少了异常磨损现象。
