A description is given of a quick-clamping device for annular bodies 3, especially rolling rings, on the free end of an overhung drive shaft 2, in which device the annular body 3 is seated coaxially and without play on a sleeve 11 and is connected by the latter to the drive shaft 2. In this arrangement, the annular body 3 lies between plane-parallel clamping surfaces 13 and 18 which can be pressed against the opposite side faces 22 and 23 of the annular body by clamping means 16 to 20 that act exclusively axially. One clamping surface 13 is formed directly on a flange 12 or a shoulder on the rear end of the sleeve 11 and has a length 14 which is significantly greater than the maximum width 15 of the annular body 3. The second clamping surface 18 is provided on a flange 17 or a shoulder of a pressure ring 16 which is slipped coaxially onto the sleeve 11 and can be pressed axially against the annular body 3 seated on the sleeve 11 by way of a clamping means 20 engaging on the sleeve 11. The sleeve 11 is on the one hand held positively in the direction of rotation by teeth 6, 25 on the drive shaft 2 and, on the other hand, is fixed non-positively on the drive shaft in the axial direction by a ring nut 20. <IMAGE>
