ABSTRACT:
Two embodiments of an overrunning roller clutch with an improved shipping retention of the rollers and energizing springs are disclosed. A second means engageable between the springs and the clutch cage confines the springs relative to the cage before the cage is installed on an inner clutch race, and thereby retains the roller against a portion of the cage. The net result is that the rollers, springs and cage are strongly retained together as a unitary assembly for shipping and handling, independent of any spring compression. The means is disengagable by the action of an outer race cylindrical surface on the rollers as the outer race is positioned relative to the inner race and installed clutch. Therefore, the springs are freed from the cage so that the rollers are not confined relative to the cage during clutch operation.
