However, in the using process, friction is generated between the bearing and the shaft, so that the temperature of the bearing gradually rises, and the using performance of the bearing is affected. In order to reduce the temperature of the bearing, some bearing housings may be cooled by adding a heat dissipation fan or using a liquid cooling method, for example, two heat dissipation methods for cooling the bearing housing by using air cooling and water cooling are proposed in two chinese patents with publication numbers CN103016389A and CN106979239A, respectively, although the above heat dissipation methods can reduce the temperature of the bearing housing to some extent, there are the following disadvantages:
