Abstract
A wedge-type mechanical servomotor has a primary member (1) with wedge faces (10) on which roll bodies (7) may move. The roll bodies (7) also engage faces (8) on abutment (9). Further roll bodies (17) engage cooperating wedge faces (16) on abutment (9) and (18) on secondary output member (19), and other roll bodies (5) engage cooperating faces (13) on abutment (9) and (14) on bushing (26), so that the device achieves essentially pure rolling movement of the roll bodies (5,7,17) which move between all faces on abutment (9) and faces (10, 14, 18) opposite to these faces (8, 13, 16) and supporting the roll bodies (5, 7, 17).
