Abstract:
1. A method for deep rolling the recesses or radii on the transitions between bearing trunnions and webs or flanges of crankshafts using a shear-type construction deep rolling unit of a deep rolling machine with two shearing arms which are connected at a rotating joint with articulation to one another comprising: arranging a deep rolling head and a support roller head as parts of a deep rolling tool and a power unit; generating a deep rolling force, via said power unit, on respective reciprocal outer ends of the shearing arms; measuring a reciprocal position that the two shearing arms momentarily occupy at the rotating joint; and simultaneously measuring an engaging depth of the deep rollers in the recesses or radii subject to the deep rolling force by while measuring the reciprocal position of the two shearing arms.
