<p>The invention relates to methods for connecting a hollow shaft to construction elements which are pushed onto the latter and have a through hole corresponding to the outside diameter of the hollow shaft, in particular for making assembled camshafts, crankshafts or gearbox shafts, by hydraulically effected expansion of the hollow shaft with plastic deformation and permanent elastic prestress in the boundary layer of the through hole in the pushed-on construction elements, in which the force of pressure at the point of connection between the hollow shaft and the through hole is considerably higher during the hydraulically effected expansion than the permanent force of pressure after completion of the expansion and, as a result, a material connection is established between the material of the boundary layer of the through hole of the construction element and the material of the plastically deformed hollow shaft.</p> |
