[0002] Slewing bearing is a new type of mechanical parts, which consists of inner and outer rings, rolling elements, etc. Slewing bearing is widely used in real industry and is called "machine joint". It is an important transmission component required for machinery that needs to make relative rotation between two objects and bear axial force, radial force and tipping moment at the same time. With the rapid development of the machinery industry, slewing bearings have been widely used in ship equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries;
