An apparatus (5) for the deep rolling of recesses (4) and radii of crankshafts (1). The deep rolling is accomplished with the aid of deep-rolling rollers (8) which, during revolution of the crankshaft (1), penetrate into the recesses (4) or radii of the crankshaft (1) under application of a deep-rol

An apparatus (5) for the deep rolling of recesses (4) and radii of crankshafts (1). The deep rolling is accomplished with the aid of deep-rolling rollers (8) which, during revolution of the crankshaft (1), penetrate into the recesses (4) or radii of the crankshaft (1) under application of a deep-rolling force and at an angle of approximately 35° and bring about a deformation in the crankshaft (1) itself. According to the invention, the depth of penetration of the deep-rolling rollers (8) in the crankshaft (1) is measured in the radial direction and the magnitude of the deep-rolling force is regulated as a function of the measured penetration depth in such a fashion that in the course of at least one revolution of the crankshaft (1) a plastic deformation corresponding to a predefined rolling depth is obtained at least at one of the two recesses (4) or radii of a relevant journal bearing (2) after the deep rolling.
