Safety-overrunning ball-type clutch parts contact interaction features

The article deals with the field of machinery, namely, with the protecting of devices for mechanical driving systems. Safety-overrunning clutches, operating on gearing principle, where safety and overrunning parts are mutually integrated, are perspectives for the  building based on modular machines. This case is due to their compactness and low components, comparatively with combined constructions. New clutch design is investigated insufficiently.
