Abstract:
A process for fastening components on a hollow shaft, during which process the components are put into specified positions on the hollow shaft and expanding the hollow shaft by introducing a pressure medium for the purpose of fastening components to the hollow shaft said process comprising the steps of:arranging a plurality of support matrices on said hollow shaft between each of the components for the purpose of bracing regions of the hollow shaft between each of the components during the expansion operation;forming the support matrices with matrix sections by placing said matrix sections together around said hollow shaft; said matrix sections forming a circular opening with a specified clearance between an inner wall of the formed support matrices and an outer surface of the hollow shaft; andforming circumferential depressions on the inner wall of the formed support matrices, said circumferential depressions enabling the hollow shaft to be expanded in the region of the circumferential depressions, for the purpose of producing bearing shoulders in the regions of the hollow shaft between the components.
