  • Patent number: 11638981
    Abstract: A rolling device for work pieces with toothing, in particular gear wheels, includes first and second shaping tools which are guided by a guide relative to the work pieces. With respect to the work pieces, a first region of a tooth flank is shaped with the first shaping tool and a second region of the tooth flank is shaped by the second shaping tool. The first and second shaping tools are respectively mounted on first and second rollers. The second roller has an axial thickness on the circumference, which differs from the axial thickness of the first roller such that the second region of the tooth flank is different from the first region.

  • Patent number: 11318538
    Abstract: A brake disc tool for machining a brake disc blank is provided. The brake disc tool includes a first cutting tool which is arranged to cut a first brake surface of the brake disc blank, a second cutting tool which is arranged to cut a second brake surface of the brake disc blank, a first forming tool for forming the first brake surface, a second forming tool for forming the second brake surface, and at least one infeed device for the infeed of the cutting tools and the forming tools towards one another, such that a brake disc blank arranged between the cutting tools and the forming tools is able to be machined and rolled in each case simultaneously on both of its brake surfaces.

  • Patent number: 9849492
    Abstract: A combined skiver and a smooth rolling tool with a skiver head and behind this a smooth rolling head, wherein between the skiver head and the rolling head an exclusive torque transmitting coupling is located which restricts the allowable axis shaft offset and/or the angular position of the axes of the rolling head and skiver head, to which the rolling head is connected, characterized in that the skiver head (2) is guided through a workpiece bore via a hydrostatic guideway.

  • Patent number: 9327329
    Abstract: The present invention describes a rolling tool device for compression rolling of, in particular, blade elements of a rotor area of a jet engine provided with a tool carrier. The tool carrier is connectable to a carrier spindle. Furthermore, two pliers-type bodies are rotatably connected to the tool carrier. The pliers-type bodies are each provided with a rolling area, with a distance between the rolling areas being variable in dependence of the rotary movement of the pliers-type bodies. In accordance with the present invention, an axis of the carrier spindle in the state connected to the tool carrier passes between the rolling areas through a contact point present at a distance between the rolling areas equal to zero.
