A conical screw connection for multi-disk shaft couplings is described, having a tension bolt ( ), a first spring collet ( ) arranged on the tension bolt and having a collar ( ), at least one second spring collet ( ) having a collar ( ) and supported by the first spring collet, with the disks of the multi-disk set being securable on said second spring collet, wherein the seat between the tension bolt and the first spring collet is conical, and the seat between the first spring collet and the second spring collet is cylindrical, and a tension element ( ) which axially clamps the disks of the multi-disk set, where the tension bolt has a threaded borehole ( ) for a screw ( ) whose head ( ) is supported on the tension element. To permit optimum clamping of the multi-disk set using the same tool for axial and radial clamping of the disks, it is proposed that a force fit or a transition fit ( ) be formed between the tension bolt and the first spring collet such that by tightening the screw, the disks of the multi-disk set are first clamped axially, and then the spring collets ( ) are widened radially.

Conical screw connection for multi-disk shaft couplings

A flexible all-steel shaft coupling includes two connecting flanges ( ) and an intermediate piece ( ) arranged between the connecting flanges, with a disk ring ( ) being arranged between each of the two connecting flanges and the intermediate piece; said disk ring being connected alternately to the respective connecting flange and the intermediate piece, by means of circumferentially-distributed studs ( ) and tension sleeves ( ), each comprising a radially protruding end stop, ( ), as well as spacer rings ( ) held on the tension sleeves, so that the connecting flanges are interconnected so as to be torsionally rigid but with angular movement and axial movement; with each of the studs ( ) connected to the connecting flanges being associated with only a single tension sleeve.
