Background

The bearing is an important part in modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the movement process of the mechanical rotating body and ensure the rotation precision of the mechanical rotating body. It is also understood that it is intended to fix the shaft. The bearing is fast, easy and excellent, and automatic selection is recorded. That is, the shaft is fixed so that it can only rotate, but controls its axial and radial movements. The motor cannot work at all without a bearing. Because the shaft may move in any direction, the motor requires only rotation of the shaft when operating. In order to reduce the influence, good lubrication must be realized on the bearings of the high-speed shaft, some bearings are already lubricated and are called pre-lubricated bearings, and most bearings must be provided with lubricating oil, so that the bearings are not only increased in energy consumption due to friction during high-speed operation, but also easily damaged. The sliding is rubbed.

The roller sheet of the roller of the existing bearing grinding machine is made of bearing steel, and the bearing steel is low in hardness and easy to wear. The roller wheel assembled has poor sealing performance and the service life of the bearing is short. The frequency of replacing the rollers is high. Thereby affecting the working efficiency of startup.
