[0002] The slewing reducer is a full-circle slewing reduction transmission mechanism that integrates a driving power source. It uses a slewing bearing as a transmission follower and a mechanism attachment. By attaching the active part, the driving source and the cover to one of the inner and outer circles of the slewing bearing, the other circle is used as both a transmission follower and a connection base for the driven working parts. In this way, the slewing bearing itself is a full-circle slewing connection part, and the driving power source and the main transmission parts are efficiently configured, making it a universal reduction transmission mechanism that integrates slewing, reduction and driving functions while having a simple structure and convenient manufacturing and maintenance.
