Research on high speed sprag overrunning clutch

摘要

The sprag overrunning clutch is an important functional unit of electro-mechanical transmission system. The defects of the overrunning clutch in traditional cage structure, such as sprag easily to roll over, large wear and poor manufacturing process, etc happened under the condition of high rotate speed. On basis of analyzing the traditional structure of cage, the main parts structure, working principle and characteristics of new-type high-speed cage structure sprag overrunning clutch have been described, and the work performance of the new overrunning clutch has been tested.
