Claim:
Deep rolling apparatus of a deep rolling machine for crankshafts, in which two arms across from each other bear a deep rolling head or a support roller head, whereby the support roller is provided with two support rollers with parallel axes and the deep rolling head with at least one work roller whose axis of rotation has the same direction as the axis of rotation of the crankshaft and forms an angle with it, with a driving device producing the closing and opening motion of the deep rolling apparatus as well as the deep rolling force, and where there is provided an axial guide roller which has a diameter that is slightly smaller than the space between two oil collars of a main or crank pin journal of a crankshaft and which has a distance to the plane containing the axes of rotation of the two support rollers wherein for a scissor type construction of the deep rolling apparatus the axial guide roller is provided on the deep rolling head and is centered relative thereto, its axis of rotation being perpendicular to the axis of rotation of the crankshaft and forms a sharp angle with a common plane of the axes of the two support rollers.
