Patent ID: 7493788

Claim:
Deep rolling head with two housings for the deep-rolling of outer radii or fillets of split-pin crankshaft lobes by means of two deep rolling rollers being pressed respectively into one of the two radii or fillets under roller force, while the crankshaft rotates around an axis of rotation, the two housings following simultaneously different movements of the journals and bear with their insides facing each other on a supporting element, whereby each of the deep rolling rollers is supported on a guide roller inside the corresponding housing so as to be rotatable in axial and radial direction, wherein the insides of the housings are each provided with an extension segment on either side of the axis of rotation of the crankshaft and at a radial distance from it, extending in a direction of a rolling force to below a contact point between the deep rolling rollers and the radii or fillets to be deep-rolled, and in that the supporting element is made in form of a sliding surface that is permanently connected to the inside and the extension of one of the two housings.
