## Abstract

The invention relates to a deep rolling roller head (1) of a deep rolling tool for deep rolling radii or recesses (22) on the main and lifting bearing journals of crankshafts (21). Said deep rolling roller head is equipped with a housing (2) inside of which one or two laterally interspaced deep rolling rollers (4) are rotationally guided in a loose manner and with little play in two roller cages (5, 6). The roller cages (5, 6) are fastened to supports (15) on the face (3) of the housing (2) oriented toward the crankshaft (21). Said supports support the roller cages (5, 6) on their faces (10) oriented away from the deep rolling rollers (4) while laterally guiding them at the same time. The face (3) of the housing (2) oriented toward the crankshaft (21) is provided, on both ends thereof, with a projection (11, 12) for supporting each of the roller cages (5, 6). A fastening and guiding element (15) is provided for each roller cage (5, 6), engages inside the roller cage (5, 6), and can be fastened to one of the projections (11, 12) of the housing (2) at the same time.

## Claims

### Claim 1

Deep rolling head of a deep rolling tool for deep rolling radii or recesses on the main and lifting bearing journals of crankshafts with a housing in which one or two laterally interspaced deep rolling rollers are rotationally guided in a loose manner and with little play in two roller cages and in which the roller cages are fastened to supports bearing the roller cages on their faces oriented away from the deep rolling rollers and at the same time guiding them laterally, characterized in that the housing (2) is provided at each of the two ends of its face (3) oriented towards the crankshaft (21) with a projection (11, 12) for the support by each of one of the two roller cages (5, 6) and in that a fastening and guiding element (15) is provided for the roller cages (5, 6) which engages inside each roller cage (5, 6) and can be attached to the projection (11, 12) of the housing (2).

### Claim 2 (depends on 1)

Deep rolling roller as in claim 1, characterized in that the fastening element is in form of a support (15) engaging inside a longitudinal groove (18) of the respective roller cage (5, 6) and is provided on its underside (3) oriented toward the crankshaft (21).

### Claim 3 (depends on 1, 2)

Deep rolling roller head as in one of the claims 1 or 2, characterized in that a spacer (20, 23) is installed between the projection (11, 12) of the housing (2) and the face (10) of the roller cage (5, 6) supported on it.

### Claim 4 (depends on 3)

Deep rolling roller head as in claim 3, characterized in that the spacer (23) can be displaced in the direction of the adjoining roller cage (5).

### Claim 5 (depends on 4)

Deep rolling roller head as in claim 4, characterized in that the position of the spacer (23) can be fixed.
