Abstract
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.
