Summary:PCT No. PCT/DE87/00571 Sec. 371 Date Jul. 24, 1989 Sec. 102(e) Date Jul. 24, 1989 PCT Filed Dec. 4, 1987 PCT Pub. No. WO88/05366 PCT Pub. Date Jul. 28, 1988.The clamping device for portable grinding machines is part of the clamping nut, which can be screwed on the threaded spindle portion of the drive spindle (10) at its free end for tightening a grinding disk. The clamping nut carries a non-rotatable and axially displaceable clamping disk. Both contain annular surfaces (25, 26) which complement one another approximately so as to form a ball groove, and balls serving to support the clamping disk can roll along these annular surfaces. The clamping disk and clamping nut are coupled via coaxial longitudinal pins which simultaneously form ball stops. A ring with a ball groove sits axially between the clamping disk (21) and the clamping nut, and radial pins projecting into the ball track press against the balls via springs. The annular surface of the clamping disk contains ball cut-out portions, the balls penetrating into the ball cut-out portions when the actuating member is rotated accompanied by axial relieving of the clamping disk (FIG. 1).
