Background

The hub bearing is one of the key parts of the automobile, and the main functions of the hub bearing are to bear the weight and provide accurate guidance for the rotation of the hub, so that the hub bearing is required to bear not only axial load but also radial load. With the progress of technological development, the hub bearing is also widely applied to a supporting structure and a coaxiality guiding function for transmitting the rotation speed kinetic energy of the long shaft of the equipment. And in the long shaft running process, the long shaft is subjected to shear pressure and radial load for a long time, and deformation and abrasion of the long shaft are easily caused. At present, the structure of the bearing seat is adopted, and the phenomenon of left-right sliding of the vibration type can exist. The operation of the equipment and the kinetic energy transmission of the rotating shaft are influenced, and the operation resistance is increased.

After the inner rings and the retainer are self-locked, the two inner rings are easy to pull out under the action of external force such as artificial tension and the like; the inner ring is provided with a clamping groove, and after the inner ring is pressed in, the clamping groove is clamped into the clamping groove of the inner ring by the clamping groove of the retainer to generate self-locking. Meanwhile, as the angular contact bearing is adopted, the curvature of the inner ring and the outer ring is larger than the radius of the steel ball, the steel ball and the raceways of the inner ring and the outer ring have a radial gap of about 0.25mm, and a certain gap is also formed between the steel ball and the ball pocket of the retainer, so that the two inner rings have larger radial and axial relative movement amounts, the locking amount between the retainer and the inner rings is unevenly distributed, and the inner rings are easy to fall off due to the influence of external force in the assembling or transporting process; the axial pulling distance of the two inner rings is about 3mm, so that the sealing ring is separated from the dustproof cover to generate a gap, external dirt and dust easily enter the bearing, and the performance of the bearing is reduced.
