An overrunning clutch comprising a drive-half (1) with axially-spaced eccentric discs (1a) 180 DEG out of phase and two longitudinal portions (1b) extending from each disc to the other on opposite sides of the plane (G) containing the eccentricities (e) of the discs; a driven half having a race (2a) whose inner surface (H) is concentric with the axis of the drive half; wedging members made as eccentric sleeves (3) with longitudinal portions (3b) embracing the discs and their longitudinal portions (1b); elements (3d) for local interaction of the eccentric sleeves (3) with the race (2a), and means limiting displacement of the eccentric sleeves (3). The latter means comprised circumferential end faces (3c) of the longitudinal portions (3b) of the eccentric sleeves (3). To this end, circumferential lengths of these longitudinal portions (3b) are made such as to enable their end faces (3c) to come into contact when the outer surface of the eccentric sleeves (3) is concentric with the inner surface (H) of the race (2a). In another embodiment, the sleeves have teeth for engaging teeth on the race. <IMAGE> |
