Abstract

The invention relates to a deep-rolling roller head (1) of a deep-rolling tool for deep-rolling, by means of deep-rolling-rollers (2), radii or recesses (3) on the main (4) and lifting bearing journal of a crankshaft, while the crankshaft rotates in a rotational direction (5). The deep-rolling roller head (1) has a prismatic, flat, approximately rectangular housing (6) on whose one front side (7), which faces the bearing journals (4) to be deep-rolled of the crankshaft, two roller cages (8, 9) are provided. The roller cages (8, 9) each have first front sides (10, 11), which are at a mutual distance (12) from each other and at the same time at a distance (13, 14) from the longitudinal center (15) of the housing (6). The roller cages (8, 9) have recesses (16), in which deep-rolling rollers of (2) are loosely rotatably guided in a removable manner with play. The roller cages (8, 9) are supported in each case with second front sides (17, 18) on parts of the housing (6) or on elements, which are adjustably fixed to the housing (6). The section (19) of the front side (7) of the housing (6) facing away from the rotational direction (5) has a projection (20) on which the roller cage (8) is supported with its second front side (17). An L-shaped retainer (22), which can be adjusted and fixed relative to the housing (6) is provided on the section (21) of the housing (6) facing the rotational direction (5) of the crankshaft. The second roller cage (9) is supported with its second front surface (18) on the end (25) of the long arm (26) of the retainer (22).
