Description

Technical Field

[0001] The utility model belongs to the field of wheel hub processing, in particular to a wheel hub bearing press-fitting device. Background Art

[0002] The wheel hub bearing is a component used on the axle of a car to bear weight and provide precise guidance for the rotation of the wheel hub. It bears both axial and radial loads and is an important part of the load-bearing and rotation of the car. The wheel hub bearing press-fitting refers to the process of using a press to press the wheel hub bearing to the center of the wheel when installing it on the wheel. When pressing, the wheel hub bearing needs to be placed in the hole in the center of the wheel first, and then the press is used to apply pressure to press the wheel hub bearing into place. The patent with authorization announcement number CN216029181U: "A wheel hub bearing press-fitting device" discloses a device for pressing a bearing into a wheel hub. Since two wheel hubs need to be pressed into the hole in the center of the wheel hub, the patent provides two sets of pressure plates to press the two bearings into the wheel hub, but this leads to structural redundancy. Therefore, we designed a wheel hub bearing press-fitting device. Utility Model Content
