  • Patent number: 7168278
    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).

  • Patent number: 7100413
    Abstract: The invention relates to a deep-rolling roller head (1) of a deep rolling tool with deep-rolling rollers (2) that are rotatably mounted in roller cages (3) and are at a distance (4) from the center (5) of the underside (6) of the housing (7) of the deep-rolling roller head (1) and are supported on the front (8) at the end of the long leg (9) of two L-shaped holding devices (11) that can be adjusted and fixed in the direction of the center (5). A first screw (13) enters an oblong hole (12) in each long leg (9) to hold the L-shaped holding device (11) on the underside of the housing (7) while a second screw (14) passes through a bore (15) in each short leg (10 and enters a bore (26) in the adjoining front (21) of the housing (7), being provided in order to adjust the precise position of the roller cage (3) relative to the center (5).

  • Patent number: 7100412
    Abstract: The invention relates to a deep-rolling roller head (1) of a deep-rolling tool for the deep rolling of radii or undercuts (22) on the main and stroke journals of crankshafts (21), with a housing (2) in which one or two deep-rolling rollers are tracked with little clearance and are loosely rotatable in a roller cage (5) at a lateral distance from each other. The roller cage (5) is attached to underside (3) of the housing (2) towards the crankshaft (21) by means of pins (15) which support the roller cage (5) on its face (10) away from the deep-rolling rollers (4) and at the same time track them laterally. The housing (2) is provided with a projection (11, 12) for the support of the roller cage (5) on either end of its underside (3) towards the crankshaft (21). Pins (15) serving as fastening and tracking elements of the roller cage (5) are provided and engage the roller cage (5).
