Description

Technical Field

[0001] The utility model relates to the technical field of slewing bearing transmission stability detection, in particular to a slewing bearing transmission stability detection test bench. Background Art

[0002] A slewing bearing is a mechanical component used to support and rotate equipment, usually used in rotating cranes, turntables, windmills and other equipment. Its main function is to provide support and reduce friction during the rotating motion of the equipment to ensure stable operation and long-term use of the equipment. A slewing bearing usually consists of inner and outer rings, rolling elements and sealing devices. The rolling elements between the inner and outer rings can reduce friction and provide good rotation performance. The sealing device can prevent dust, water and other impurities from entering the slewing bearing and extend its service life. The selection and installation of the slewing bearing needs to be comprehensively considered based on factors such as the load, speed, working environment and installation space of the equipment to ensure that it can meet the working requirements of the equipment and has a long service life.

[0003] Since slewing bearings are mostly used in the fields of marine equipment, engineering machinery, etc., high performance requirements are required for them, and transmission stability tests are required before they leave the factory. The current slewing bearing test bench cannot be adjusted in size and cannot adapt to various types of slewing bearings. In addition, some outer rings have teeth and are not easy to fix.
