  • Publication number: 20100172606
    Abstract: The invention relates to a method for the production of a roller bearing (5) which does not require machining, wherein the roller bearing (5) has a bearing inner ring and a bearing outer ring (3a?, 3b?) and at least one rolling body row (9) guided between said rings in raceways (8a, 8b). In order to be able to implement the production of the bearing rings (3a?, 3b?) including the raceways (8a, 8b) for the rolling bodies (9) according to a forming method which does not involve machining, in a manner which is more cost-effective with respect to known production methods, a ring element (3) is initially produced from a sheet metal blank (1) by means of dies and pressure forming, the ring element having a section (3a) lying radially on the inside, a ring-shaped section (3b) lying radially on the outside, and having a central recess (4), raceways (8a, 8b), and preferably a set breaking point (6) between the two ring-shaped sections (3a, 3b).

  • Publication number: 20090317030
    Abstract: The invention relates to an angular contact roller bearing having an outer bearing ring, an inner bearing ring, a plurality of ball rollers arranged between the rings, and a bearing cage. The ball rollers in the two adjacent rows have pressure angle axes extending parallel to one another and are arranged directly one next to the other with their side faces point toward one another. Adjacent ball rollers in the two rows are arranged on a common rotational axis. The ball rollers have diameters and widths which are dimensioned in such a way that envelope cones which form tangents with all the ball rollers at their diameters are arranged with their cone tips precisely at the intersection point of the common rotational axes of the bearing longitudinal axis.

  • Patent number: 7631948
    Abstract: The invention relates to a wheel hub having a central section and a radial section which is radially connected to the central section, a bearing section which axially protrudes from the central section and is used to receive a wheel bearing, and an axially opposing receiving section for receiving a brake disk and a wheel rim. Holes for receiving wheel nuts are formed in the radial section. In order to produce an especially light wheel hub that can withstand all operating loads and provides a brake disk with a secure abutment surface under all operating conditions, the wheel hub has recesses at least between some holes, the recesses fully penetrating the wall of the radial section of the wheel hub.

  • Publication number: 20080303339
    Abstract: The invention relates to a wheel hub having a central section and having a radial section which radially adjoins said central section, having a bearing section which projects axially from the central section for holding a wheel bearing and having an axially opposite holding section for holding a brake disk and a wheel rim, wherein holes for holding wheel bolts are formed in the radial section. In order to obtain a particularly light wheel hub which can withstand all operating loads and offers a reliable contact face for a brake disk under all operating conditions, it is provided that the wheel hub has recesses at least between some holes, which recesses extend completely through the wall of the radial section of the wheel hub, and that stiffening ribs are formed between the respective recesses which stiffening ribs axially thicken the radial section between the recesses.
