The slewing bearing is a new type of mechanical component. It has inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing capable of withstanding the combined load, and can withstand large axial, radial loads and overturning moments at the same time. The slewing bearing is widely used in the real industry. It is called "the joint of the machine", which is a mechanical device that needs to perform relative rotary motion between two objects, and also needs to bear axial force, radial force and tilting moment. Important transmission components required. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.
According to the actual use and design structure have different working methods, there are two basic working methods:
the inner ring fixes its supporting role, the outer ring rotates
the outer ring fixes its supporting role, the inner ring rotates
