  • Publication number: 20190111466
    Abstract: A rotary flow forming apparatus for producing light alloy rims contains a main spindle with a clamping apparatus for a rim blank. An outer pressure roller is provided and is deliverable radially from the outside in and is movable parallel to the spindle axis, for producing an outer contour of the light alloy rim. The apparatus does not require massive internal dies and thereby significantly reduces the production costs and significantly improves the efficiency of rim production, which is achieved by the fact that the rotary flow forming apparatus has an inner pressure roller for generating an inner contour of the light alloy rim, which is arranged in the region of the inner side of the rim blank opposite the outer pressure roller and is mounted so as to be movable parallel to the spindle axis, rotatable, and deliverable radially from the inside outward to the rim blank.

  • Patent number: 8823239
    Abstract: The invention relates to an electrical machine (8), in particular an electric motor, suitable for the adjustment by external force of elements of a motor vehicle, essentially for driving a steering booster. The inventive electrical machine comprises a rotor (7) and a shaft (10), the rotor having a plurality of plates (5), wherein the plates (5) are premounted on the shaft either individually or as a plate assembly (6) or by means of a plurality of plate assemblies (6), the rotor (7) being connected to the shaft (10). The plates (5) have resilient lugs (3) for fixing the plates (5) and/or plate assemblies (6) to the shaft (10). Furthermore, the plates (5) of the plate assemblies (6) comprise centering lugs (1) which serve to radially center the plate assembly (6) relative to the shaft (10).
