Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, and particularly relates to a bearing clamping fixture and an assembly production line. Background Art

[0002] A bearing is a mechanical component that plays a very important role in machinery. Its main functions are to support the shaft and the parts on the shaft, maintain the rotational accuracy of the shaft, and reduce the friction and wear between the shaft and the support. First of all, the bearing is a component used to support the shaft. It can bear radial loads and axial loads to ensure the normal rotation of the shaft. At the same time, it can also support the parts on the shaft to keep them in the correct position. Secondly, the bearing can maintain the rotational accuracy of the shaft. Since the inner and outer rings and rolling elements of the bearing are precision machined, the rotational accuracy of the shaft can be guaranteed to meet the needs of various machinery. Then, the bearing can reduce friction and wear. Since there is lubricant inside the bearing and the rolling elements roll between the inner and outer rings, the friction and wear can be greatly reduced, and the service life of the machinery can be extended. Finally, the bearing can also reduce the energy consumption of the machinery. Because the friction coefficient of the bearing is small, the energy consumed by the machinery during operation is also small. Generally speaking, the bearing is a very important mechanical component. Its main role in machinery is to support the shaft and the parts on the shaft, maintain the rotational accuracy of the shaft, reduce friction and wear, so as to improve the efficiency and service life of the machinery.
