ABSTRACT:
In a method and a device for non-rotatably connecting a hollow shaft with at least one component located on the hollow shaft with which the component is positioned with clearance on the hollow shaft and is fastened thereon in a certain position by eliminating the clearance, the clearance being eliminated by expanding the hollow shaft using a joining tool that passes through at least part of the hollow shaft, and the joining tool including at least one first shaping element and at least one further shaping element, and the shaping elements being movable relative to each other, so that the motion of the shaping elements relative to each other causes an at least partial expansion of the hollow shaft. A design of this type has the advantage, in particular, that the joining tools cause the hollow shaft to expand only at the necessary points.
