ABSTRACT:
A deep rolling roller head includes two housings for the deep rolling of the outer radii or fillets of split-pin crankshaft journals by means of two deep rolling rollers which are pressed into one of the two fillets under a rolling force while the crankshaft rotates around its axis of rotation. The two housings follow at the same time the different movements of the journals and support each other with their insides across from each other on a bearing plate. The insides of the housings bear on either side of the axis of rotation of the crankshaft and at a distance from it on an extension segment extending in the direction of the rolling force to below a contact point between the deep rolling rollers and the fillets to be deep-rolled. The bearing plate connected permanently to the inside and the extensions of one of the two housings.
