Method and device for reinforcing crankshafts

Abstract

The present invention relates to a device and a method for surface rolling crankshafts at the transition radii of bearing journals. The method for surface rolling the transition radii of crankshafts comprises the following steps: providing at least one roller element for applying at least one force to the workpiece; providing at least one support element for supporting the workpiece against a force applied by a roller element; displacing the at least one roller element and/or the at least one support element such that the at least one support element, and the at least one roller element, perform a displacement relative to each other, the displacement having a linear component. The present invention further provides a roller element for surface rolling the transition radii of crankshafts having a substantially linear contact surface for introducing at least one surface rolling force into a crankshaft, and a corresponding device.
