<p>An overrunning clutch is disposed with a revolving leading-in mechanism (M3), a revolving leading-out mechanism (M2), and a fixed-point actuating mechanism (M4) which controls the precise action of the leading-in mechanism (M3). The leading-in and leading-out movement of a movable ring relative to a fixed ring are both made along a fixed helical rail. The movements are accurate in both axial direction and circumferential direction without any errors, and are not effected by rotational speed and wear. Furthermore, simply changing and locking the relative position of a leading-out ring of the leading-out mechanism (M2) can change the operating direction of the clutch, and make the particular fixed-point actuating mechanism (M4) inactive, so that the clutch transforms into a unidirectional or bidirectional overrunning clutch, a gliding device, a joint, or a simple clutch, and so on.</p> |
