  • Method and apparatus for extending the life of a wrap spring clutch
    Patent number: 4760903
    Abstract: A method and apparatus for extending the life of a control or drive spring in a wrap spring clutch. The tang of the control spring fits into a control slot of a control collar which rotates when the clutch is actuated. When the clutch is actuated, the control spring "wraps down" on both a rotating input member and the output shaft of the clutch to transfer the rotary motion of the input member to the output shaft. An elastomeric sleeve which is dimensioned to provide an interference fit between the tang and control slot of the control member is positioned on the tang and inserted in the control slot to remove any looseness or play between the tang and the control slot and thereby extend the life of the control spring and clutch.
