ABSTRACT:
A gear mechanism containing a clutch assembly made of an outer member and an inner member wherein the rotation of the inner member is less than one revolution. The inner member has a chord surface, and when inserted in the outer member a wedge shaped space is created. Rolling elements are mounted in the wedge shaped space such that when there is rotation of one of the members, the rolling elements are driven into one of the corners of the wedge shaped space causing the inner member to rotate with the outer member. A protrusion at a fixed location is used to dislodge the rollers. With the rollers dislodged, the inner member ceases rotation. Four embodiments are disclosed. In the first embodiment, two magnetic rollers are used to provide an engagement mechanism between the rollers and the corner of the wedge shape. The second embodiment discloses a single magnetized roller. The third embodiment discloses a spring separator positioned perpendicular to the chord to position two non-magnetic rollers. The fourth embodiment uses a spring separator position parallel to the chord to position two non-magnetic rollers. In applications where, in one direction, a rotation of less than one revolution is acceptable, the use of a fixed protrusion to dislodge the rollers allows the full torque of the driving member to drive the mechanism in either rotational direction.
