Abstract:
1. Deep-rolling roller head of a deep-rolling tool for the deep rolling of radii or undercuts on the bearing journals of crankshafts by means of deep-rolling rollers that are freely rotatable in roller cages, that are supported at a distance from each other nearly in the center of an underside of a prismatic housing of the deep-rolling roller head towards the crankshaft, each on a front of a long leg of two L-shaped holding devices each possessing one long and one short leg, whereby a holding device can be adjusted and fixed in a direction of the center of the underside in that the long leg is provided with an oblong hole into which a first screw is inserted and by which the L-shaped holding device concerned is held on the underside of the housing while a second screw passes through a bore in the short leg and enters with its outer end into a bore at the face of the housing adjoining the underside, whereby the second screw is provided to adjust the precise position of the roller cage in relation to the center of the underside, wherein one of two faces of the housing adjoining the underside is at a predetermined first distance from the center of the underside over at least a segment of its length, the short leg of one of the two L-shaped holding devices is supported over at least a portion of its inside towards the housing on the segment of the housing that is at a first distance from the center of the underside, while the front of the long leg of this holding device supporting an adjoining roller cage is at a predetermined second distance from the segment of the housing on which the short leg is supported.
