The invention discloses a bearing anti-disengagement structure and a hub reduction gear. The bearing anti-disengagement structure comprises a fixed piece, a rotating piece, a rotating bearing and an anti-loose adjusting assembly. The rotating piece sleeves the outer side of the fixed piece. The rotating bearing is disposed between the fixed piece and the rotating piece and used for rotationally connecting the fixed piece with the rotating piece. The anti-loose adjusting assembly is disposed on the fixed piece and abuts against the rotating bearing. The anti-loose adjusting assembly is used foraxially adjusting the axial play of the rotating bearing and locking the rotating bearing. By means of the technical scheme, the axial play of the rotating bearing can be adjusted, so that the rotating bearing has sufficient allowance in work for hot expansion and cold contraction, and the failure of the rotating bearing can be prevented; and the anti-loose adjusting assembly can also lock the rotating bearing to prevent the connection failure of the rotating bearing, so that the rotating piece and the fixed piece are more reliably connected.
本发明公开了一种轴承防脱结构及轮边减速器。该轴承防脱结构包括固定件、转动件、转动轴承及防松调节组件;转动件套设于所述固定件外;转动轴承设于所述固定件和所述转动件之间,用于转动连接所述固定件和所述转动件;防松调节组件设于所述固定件上、且与所述转动轴承抵接,所述防松调节组件用以从轴向调节所述转动轴承的轴向游隙、并锁紧所述转动轴承。本发明提供的技术方案可使所述转动轴承的轴向游隙可以调节,从而使所述转动轴承在工作时有充足的余量以进行热胀冷缩,可防止所述转动轴承失效;且所述防松调节组件还可以锁紧所述转动轴承,以防止所述转动轴承连接失效,从而使所述转动件和所述固定件的连接更可靠。
