Patent ID: 8677581

Claim:
A deep rolling machine for crankshafts with several deep rolling units in a scissor-type configuration which are with lateral distances one next to another hinged to the deep rolling machine in the direction of the axis of rotation of the crankshaft, so that some deep rolling units are provided for the deep rolling of the main bearing journals and other deep rolling units for the deep rolling of the pin bearing journals of the crankshaft and the deep rolling units at the outer ends of their two scissor-type arms carry a deep rolling head and a supporting roller head respectively that form together a deep rolling tool where the deep rolling units have respectively a width that is small when compared to their length, wherein at least one of the deep rolling units intended for the deep rolling of the main bearing journals or of the pin bearing journals features a device that attacks the crankshaft when the at least one of the deep rolling units is in its working position and that stabilises the deep rolling units in the direction of the axis of rotation of the crankshaft.
