The invention discloses a bicycle center shaft sleeving structure, which belongs to the technical field of bearings, and is characterized in that the bicycle center shaft sleeving structure comprises a release bearing seat, a sealing assembly is arranged at the top end of the release bearing seat, and a fixing assembly is arranged at the bottom of the release bearing seat. The deep groove ball bearing is connected to the periphery of the supporting sleeve in a sleeving mode along the release bearing seat, then the sealing cover penetrates through the release bearing seat to wrap the deep groove ball bearing, and then the supporting sleeve and the sealing cover are locked and fixed through the hand screwing bolt, so that the deep groove ball bearing can be located in a space formed by the supporting sleeve and the sealing cover, and the sealing performance is greatly improved; according to the deep groove ball bearing, lubricating oil leakage caused by long-time work is avoided, meanwhile, the deep groove ball bearing can be conveniently disassembled and overhauled in the later period, the deep groove ball bearing connected to the periphery of the supporting sleeve in a sleeving mode can be positioned through the positioning assembly, and the stability between the deep groove ball bearing and the supporting sleeve is greatly improved.

    本发明公开了一种自行车中轴套装结构,属于轴承技术领域,其技术方案要点包括分离轴承座,所述分离轴承座的顶端设置有密封组件,所述分离轴承座的底部设置有固定组件,通过密封组件,在使用时,将深沟球轴承沿着分离轴承座套接在支撑套的外围,再将密封盖穿过分离轴承座将深沟球轴承包裹,然后使用手拧螺栓将支撑套与密封盖进行锁紧固定,从而深沟球轴承会在支撑套和密封盖形成的空间内,大大提高密封性,避免长时间工作导致润滑油泄露,同时方便后期对深沟球轴承进行拆卸检修,通过设置定位组件,能够对套接在支撑套外围的深沟球轴承进行定位,大大提高深沟球轴承与支撑套之间的稳固性。
