Abstract
The invention refers to a device for producing a friction joint incorporating two members (1,2) having concentric opposite and mainly tapering surfaces, which are squeezed against each other at a relative axial displacement in one direction. The joint preferably incorporates a sleeve, on which one of said surfaces is arranged and for obtaining a minimum radial extension are the joint surfaces in longitudinal section provided with a saw tooth contour, which can be formed by a number of taper portions arranged in a row or by a helical ramp (6), which forms an angle to the center axes of the members.
