  • Patent number: 5707275
    Abstract: In a clamping device for clamping a disk-shaped tool to a threaded spindle of a hand-held machine tool, a nut part, which can be screwed onto the threaded spindle, presses a face plate against the tool. An axial rolling bearing is arranged between the nut part and the face plate. To achieve simple and reliable manual clamping and release, in conjunction with a slip clutch function under overload, a spring is arranged between the face plate and the nut part next to the axial rolling bearing. The spring forms a non-rotatable frictionally engaged connection between the nut part and the face plate. The axial rolling bearing supports the face plate on the nut part. The nut part slips in relation to the face plate when an upper limit value of the torque transmitted is exceeded, and the axial rolling bearing rotates.
