| 摘要 |
The invention relates to a process for producing a connection between a hollow shaft and design elements slid on to the shaft and having an aperture which corresponds to the outer diameter of the hollow shaft, especially for producing assembled camshafts, crankshafts or transmission shafts by hydraulically expanding the hollow shaft, a process which results in plastic deformation and permanent elastic pretension in the surface layer of the aperture of the slid-on design elements and in the case of which the compressive force in the connected region between the hollow shaft and the aperture is very much higher during the hydraulic expansion process than the remaining compressive force after completion of the expansion process. As a result, there occurs a material-locking connection between the material of the surface layer of the aperture of the design element and the material of the plastically deformed hollow shaft.
