Introducing Automobile Hub Bearing Units

carhubThe inner ring of the bearing unit is prone to axial sliding. At present, a large number of thread structures are used for fixing and locking. SomeCar wheelsThe flange neck of the bearing unit has threads, and the method of nut locking is relatively difficult. Some automobile wheel bearing units adopt various nylon self-locking and pin-assisted anti-loosening methods, but this will cause complex structures and difficult assembly. .

Provide an automobile hub bearing unit locked by locking screws, which solves the problem of difficult locking and easy axial sliding of the inner ring of the existing automobile hub bearing unit. The automobile hub bearing unit includes bearings and flanges.

There is a step on the neck of the flange, and the bearing sleeve is on the surface of the outer ring of the flange and one end of the inner ring of the bearing near the step. There is an internal thread in the center hole of the flange, and there is a locking screw on the internal thread. The thread fits, and the end of the locking screw is close to the inner ring of the bearing.

The central thread of the inner ring of the bearing is used to compress the anti-loosening thread of the inner ring of the bearing. The anti-loosening screw can effectively prevent the loosening of the thread structure and make the inner ring of the bearing loose, thereby improving the service life of the hub bearing and at the same time acting as an axial predictor. Tight and anti-loose effect.
