Abstract:
A rotational coupling is provided. The coupling includes first and second hubs disposed about an axis of rotation. A wrap spring is disposed radially outwardly of the hubs and rotatably couples the hubs upon rotation of the first hub in a first rotational direction. A spring actuation member is configured for rotation about the axis and coupled to one end of the wrap spring. The opposite end of the wrap spring is coupled to the second hub. An actuator is configured to selectively stop rotation of the spring actuation member and the second hub in the first rotational direction and cause rotation of the spring actuation member in a second rotational direction to thereby unwrap the wrap spring. The rotational coupling therefore facilitates disengagement of the wrap spring from the first hub during release of the coupling to prevent undue noise and vibration and reduce wear.
