Abstract

A process for producing a frictionally locking connection of two structural component parts, especially a shaft and a hub, including plastically deforming a round structural component part into an oval or polygonal shape by applying force, applying additional force to substantially elastically round the oval or polygonal structural component part, assembling the structural component parts while maintaining the additional force, and then cancelling the additional force so that the round structural component part springs back into the oval or polygonal shape whereby the structural component parts are connected with one another by a press fit.
