摘要： A device for axially clamping a disc-shaped tool on a flange of a driven spindle with a threaded end, includes a clamping nut, a clamping disc supported on the clamping nut for biasing the disc against the flange and connected with the clamping nut for joint rotation therewith and axial displacement relative thereto, and supporting bodies arranged between the clamping nut and the clamping disc. An actuating member is located between the clamping nut and the clamping disc, and rolling bodies are displaceable along guide paths defined by guide tracks of the supporting bodies and guide track means of the actuating member for radially loading the supporting bodies. An insert member is supported between the clamping nut and the clamping disc and includes a plurality of stops projecting into the guide paths. The actuating member presses the rolling bodies against the stops upon rotation in a first direction corresponding to a clamping direction, and displace the rolling bodies into associated radial recesses thereon upon rotation in a second direction opposite to the first direction to relieve the supporting bodies from radial loads and to relieve the clamping disc from an axial clamping pressure.
