  • Patent number: 10502260
    Abstract: Tapered roller bearings and methods of producing the same are disclosed. One method is for producing an inner ring for a tapered roller bearing in which the inner ring comprises a raceway portion and a fixed edge portion. The method may include providing an inner ring blank and an unfinished fixed edge portion. The inner ring blank may include an unfinished raceway portion and the unfinished fixed edge portion may have a larger outside diameter than the unfinished raceway portion. The inner ring blank may have a through-opening. The inner ring blank may be formed into the inner ring by extrusion in a main forming step, the unfinished fixed edge portion being transformed into the fixed edge portion and the unfinished raceway portion being transformed into the raceway portion. The inner ring may be formed in its final contour without any cutting.

  • Patent number: 10465744
    Abstract: Bearing assemblies, such as angular contact bearing assemblies, and methods of producing the same are disclosed. One angular contact ball bearing may include an inner ring and an outer ring, the inner ring having an outer raceway and the outer ring having an inner raceway. A plurality rolling elements may be arranged between the outer raceway and the inner raceway. The outer raceway may be formed by an extrusion of the inner ring and/or the inner raceway may be formed by an extrusion of the outer ring. The raceways may be extruded in their final contour, without any cutting.

  • Publication number: 20180363700
    Abstract: Cylindrical roller bearings and methods for the production thereof are disclosed, wherein the cylindrical roller bearings can be manufactured inexpensively and with adequately high quality. The cylindrical roller bearing may have an inner ring, an outer ring, and a multiplicity of cylindrical rollers, wherein the cylindrical rollers are arranged between the inner ring and the outer ring. The outer ring has an internal raceway for the cylindrical rollers, a fixed-rim portion, and a flanged-rim portion. The inner ring has an external raceway for the cylindrical rollers, and the internal raceway and/or the external raceway are/is formed into a final contour by extrusion.

  • Publication number: 20180238390
    Abstract: A method is disclosed for producing a tapered roller assembly which can be mounted in a particularly simple manner. For this purpose, a method for producing a tapered roller assembly having an inner ring and a roller ring is proposed, wherein the method comprises the following steps: a) providing the inner ring , wherein the inner ring has a flanged mounting rim which is produced within a preliminary flanging stage by flanging over an edge region of the inner ring; b) mounting the roller ring on the inner ring, wherein the roller ring is pushed over the flanged mounting rim onto the inner ring; c) flanging over the flanged mounting rim into a flanged rim wherein the flanged rim, as a retaining rim, captively retains the roller ring; and d) heat treating the flanged mounting rim before step b) or step c), wherein a hardness of the flanged mounting rim is reduced by comparison with a hardness of a raceway of the inner ring. Also proposed is a tapered roller bearing formed with such a tapered roller assembly.

  • Publication number: 20140068947
    Abstract: A method for producing a bearing ring (20, 29), in particular a tapered roller bearing ring, including the following steps: making available an annular disc (8; 9), and forming the disc (8; 9) to provide a substantially cylindrical bearing ring and producing a raceway (19; 28) of the bearing ring in a single operation by extrusion. According to the invention, the method achieves the object of providing a simple method for producing bearing rings, in particular for tapered roller bearings, which delivers high unit numbers and in which it is possible to dispense with a finishing operation.
