  • Patent number: 9360049
    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.
