Abstract: A bearing position for rotatably mounting a shaft or an axle in a housing. The bearing position comprises a rolling bearing, which is designed as a roller bearing, with a bearing ring, which is assigned to the housing, where said bearing ring forms an outer rolling raceway, which faces radially inwards and on which rolling elements are guided, said rolling elements mutually interacting with a shaft, which forms an inner rolling raceway, or with an inner bearing ring. A polygonal bearing is provided as the roller bearing; and said polygonal bearing encloses a bearing ring with at least one elastic section, which forms a transversely convex raceway curvature. This arrangement guarantees that at least one rolling element is supported and guided in a radially prestressed manner without radial clearance on the rolling raceway.

Abstract: A bearing configuration for the purpose of mounting a shaft or axle in a housing in a manner allowing rotation. The bearing configuration has a rolling bearing designed as a roller bearing with at least one bearing ring which is functionally assigned to the housing, said bearing ring forming an outer race facing inward radially, wherein rolling elements are guided on said outer race, working together on the opposite side with a shaft which forms an inner race. The roller bearing of the bearing configuration is a combination of at least two joined polygonal bearings, wherein each polygonal bearing on the bearing ring includes at least one elastic segment which forms a convex, transversely rounded race curvature. This configuration ensures that at least one rolling element is radially pretensioned and supported on the outer race of the shaft, and the shaft is guided in the housing with no radial play.

Abstract: A bearing pin for a planetary transmission, which has a cylindrical base body with a radial bore formed in one axial end of the base body. A locking element is mounted with a salient radial portion in the radial bore and serves as an anti-rotation feature of the base body. The bearing pin creates a possibility of reliable fixing of a bearing pin in a planetary transmission with a low-complexity manufacturing procedure. Also, a carrier arrangement for a planetary transmission, which includes such a bearing pin is disclosed.

Abstract: A raceway bushing which has a substantially cylindrical peripheral wall that forms a bushing inner surface and a bushing outer surface, a bottom wall which extends from the peripheral wall and has an inner bottom surface and an outer bottom surface, and a bottom opening configured in the bottom wall. The bottom opening is bordered by an annular collar that rises axially beyond the inner bottom surface.

Abstract: The invention concerns an interference fit comprising a carrier and at least one stepped bushing seated with an interference fit on the carrier. The stepped bushing is made by shaping a sheet metal and is characterized by a special wall thickness configuration. Through this wall thickness configuration, it becomes possible to assure that the stepped bushing conforms to close shape tolerances in the pressed-in state in regions of functional relevance.

Abstract: A drive shaft, in particular a radial shaft for a gas-turbine engine, includes a metallic and hollow shaft shank 1 with load transfer elements 2, 10, 11 integrally formed onto its ends. The shaft shank 1 includes a metal tube 3, 9 prefabricated as a semi-finished part, designed only for transmission of torsional loads and having a constant wall thickness. An outer or inner reinforcement 5, 8 intended only for ensuring the necessary bending stiffness is provided on the outer and/or inner circumferential surface of the metal tube 3, 9 and made from a fiber-composite layer 13, 13? with fibers oriented in the longitudinal direction of the drive shaft. The inner fiber-composite layer 13 acting as outer reinforcement 5 is sheathed with an outer fiber-composite layer 14 made from fibers oriented at an angle of 60° to 90° relative to the longitudinal direction.

Abstract: A radial roller bearing arrangement in which at least one retaining projection is provided as an anti-rotation feature of an outer ring. The projection is located on an inner diameter of a fixed rim formed on one axial side of the outer ring, so that the outer ring can be implemented with a radially inward-pointing flanged rim on its other axial side that can be formed after insertion of a needle roller and cage assembly to act for holding the needle roller and cage assembly in the outer ring.

Abstract: A method for improved determination of the position of a user device in a mobile-radio network is provided. In combination with adjacent, second user devices, the method is intended to achieve a relatively-accurate positioning even if only a relatively-inaccurate positioning method is available for the user device itself, especially if the latter is disposed inside a building. An absolute position of a second user device is determined with a first position-determining method. A relative position of the first user device relative to the second user device is then determined with a second position-determining method. Finally, the absolute position of the first user device is determined on the basis of the absolute position of the second user device and the relative position of the first user device relative to the second user device, wherein the first and the second position-determining methods are different methods.
