Abstract
An axial bearing for reducing wear is provided in an overload clutch for arrangement between a drive unit and a power take-off unit of a hand-held power tool in order to enable decoupling of the drive unit from the power take-off unit in the hand-held power tool when a limit torque is exceeded.
Claims11
An overload clutch designed to be arranged between a drive unit and a driven unit of a hand-held power tool that is driven by the drive unit, the overload clutch comprising:
- a rotating slip clutch configured to be connected between the drive unit and the driven unit in the hand-held power tool and to enable decoupling of the drive unit from the driven unit when a limit torque is exceeded;
- and
- an axial bearing disposed in said rotating slip clutch and configured to reduce wear between rotating components of the rotating slip clutch, wherein;
- the rotating slipping clutch has an associated axis of rotation and includes a spring element and detent bodies acted upon by the spring element;
- and
- the axial bearing is arranged in the direction of the axis of rotation between the spring element and the detent bodies.
