Abstract

A method and device for joining assembled hollow shafts which consist of a tube and several attachable parts such as cams, flanges, bearing sleeves, pulse generating devices, toothed gears and chain gears slid on to the tube, wherein the tube, inside the attachable parts, is radially plastically expanded in individual portions by applying internal pressure in such a way that the attachable parts are secured to the tube by a permanent press fit, wherein the attachable parts and the tube are individually positioned and fixed relative to one another and wherein the tube is sequentially plastically expanded in individual portions associated with the individual attachable parts.
