  • Elastomeric energizer for sprag clutch
    Patent number: 4373620
    Abstract: An elastomeric energizer for a sprag clutch provides an improved mechanism for engaging the circumferentially spaced sprags thereof with the inner and outer races of the clutch. The energizer also dampens sprag oscillations, thereby cutting clutch chatter, and avoiding localized stresses on the energizing surfaces of the sprags. In a preferred embodiment, the sprag energizer is an O-ring contained within an annular recess formed by grooves in the sides of the individual sprags.
