Abstract

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.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a bearing detachment prevention structure and a wheel-side reducer. Background technique [0002] In heavy-duty vehicle wheel reducers, round nuts can be used to fix a pair of back-to-back tapered roller hub bearings, and can also adjust the clearance of the bearings. The alternating load from the wheel constantly impacts the hub bearing, which is then transmitted to the round nut. If the connection and fixation function of the round nut fails, it will cause a major accident that the wheel and the frame will loosen or even disintegrate. Therefore, the reliability of the anti-loosening performance of heavy-duty automobile round nuts is of great significance. Contents of the invention [0003] In order to solve the above technical problems, the main purpose of the present invention is to provide a bearing detachment prevention structure and a wheel reducer, aiming at improving...
