The invention concerns a device for displacing or rotating at least two components (10, 11) relative to each other, said device having a coupled gear which comprises a pressure element (16a). The pressure element (16a) urges rolling bodies, which move in mountings (14a) in a rolling body cage transversely to the direction of displacement (x), so that they can mesh with various parts of a transmission element (17). The division ratio of the mutual spacings between the parts which can mesh is at least slightly different from that of the spacings between the mountings (14a) for the rolling member cage (14). Since the parts which can mesh take the form of conical or frustoconical bores (17a) on whose flanks (17b) the rolling bodes support one component on one face which is parallel to the face in which the bores (17a) are provided, high forces can be transmitted. |
