Description

Technical Field

[0002] A bearing is a mechanical component whose main function is to support a mechanical rotating body, reduce its friction coefficient during rotation, and ensure rotation accuracy. In modern industry and transportation, bearings play a vital role in the transportation field. The primary function of high-rigidity riveted hub bearings is the same as that of ordinary bearings, which is to support the hub for rotation. During vehicle driving or mechanical operation, the hub needs to rotate stably around the axle or center axis.

[0005] Precision manufacturing technology: in the manufacturing process of bearings, high-precision processing equipment and processes are used to ensure the dimensional accuracy and shape accuracy of each component;

[0006] Riveting technology is used to achieve a firm riveting connection between the bearing and the hub.

[0007] Lubrication technology, lubrication plays an important role in reducing friction and wear of bearings and improving their stiffness-related performance.

[0008] During the implementation of existing high-rigidity riveted wheel hub bearings, at least the following technical problems were found: after the existing bearings are used in automobile wheel hubs, continuous vibration will be generated during the driving of the automobile. During the continuous vibration, the bolts or nuts connecting the bearings will become loose. The loosened bolts or nuts may cause the wheel hub and the bearing to loosen, which will produce abnormal noise during the driving of the car and affect the driving experience. At the same time, the loosened bolts or nuts will cause a small collision with the bearing flange during the continuous vibration, affecting the service life of the bearing flange, bolts and nuts, and thus affecting the service life of the bearing.
