[0002] Thrust ball bearings are designed to withstand thrust loads when running at high speeds. They are composed of a washer-shaped ring with a raceway groove for the ball to roll. Since the ring is seat-shaped, thrust ball bearings are divided into two types: flat seat pad type and self-aligning spherical seat pad type. In addition, this type of bearing can withstand axial loads, but not radial loads.

[0003] The thrust ball bearing of the prior art mainly includes a shaft ring, a seat ring, a steel ball retainer and a steel ball body. When in use, the steel ball body and the steel ball retainer are installed, at which time the shaft ring and the seat ring are fixed to the steel ring retainer, and then the shaft ring is fixed to the shaft, and the seat ring is fixed to the shell and can be used.

[0004] However, in actual use, the rotation between the shaft ring, the seat ring and the steel ball body will increase the friction, which in turn increases the temperature and shortens the service life of the shaft ring and the seat ring. Adding lubricating oil requires shutting down the equipment connected to the bearing. Frequent addition of lubricating oil will reduce the working efficiency of the machine. Utility Model Content
