  • Patent number: 11273400
    Abstract: A structural unit includes a cylindrical component and a metal-plate element having a through-neck, and the cylindrical component extends though the through-neck and is attached to the cylindrical component. The through-neck substantially determines a position of the metal-plate element relative to the cylindrical component with respect to a radial direction of the cylindrical component. Also an oil mist separator including the structural unit.

  • Patent number: 11193542
    Abstract: A sealed universal joint bearing includes a pot-shaped component having a disk-shaped base and a cylindrical wall projecting from a periphery of the base, and an inner surface of the base and an inner surface of the cylindrical wall define an interior of the pot-shaped body. At least one row of rolling elements are configured to roll along the inner surface of the cylindrical wall. A flange in the interior of the pot-shaped component has a flange surface against which end sides of the rolling elements are configured to slip during bearing operation, and the flange surface includes at least one formation configured to reduce a contact area between the flange surface and the end sides of the rolling elements.

  • Patent number: 9939023
    Abstract: A bearing assembly includes a roller bearing connected with a plate-shaped bearing support. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support. The two affixing plates clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and a spring element configured to act in the axial direction is disposed between one of the two affixing plates and the bearing support.

  • Patent number: 9841057
    Abstract: A bearing assembly includes a roller bearing connected with a bearing support having a plate-shaped section. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support and that clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and the two affixing plates have a different mechanical strength.

  • Patent number: 9835203
    Abstract: A bearing arrangement is disclosed having a bearing and a bearing support. The bearing is coupled to the bearing support at an axial side. The bearing provides first and second bearing rings that define a bearing interior there between. A first groove is formed at the first bearing ring's radial side facing the second bearing ring. A coupling element is arranged at the bearing's axial side facing the bearing support. The coupling element includes a first, preferably nose-shaped, radial protrusion that is in engagement with the first groove, and a second radial protrusion, which at least partially encompasses the bearing support at a side facing away from the bearing, so that the coupling element fastens the bearing to the bearing support. A coupling element for such a bearing arrangement is also provided.

  • Patent number: 9103375
    Abstract: A cartridge bearing assembly for rotatably coupling a shaft with a housing includes a bearing having a central axis and opposing axial ends. The bearing includes first and second, axially spaced inner rings disposeable upon the shaft, at least one outer ring disposed circumferentially about the two inner rings, and first and second sets of rolling elements disposed between the inner and outer rings. A carrier includes a first tubular portion disposed generally about the bearing first axial end and a second tubular portion disposed generally about the bearing second axial end. The first and second tubular portions are coupled together to enclose the bearing, the carrier being at least partially disposeable within the housing bore so as to couple the bearing with the housing. Preferably, a coupler is provided to connect the first and second inner rings so as to establish preload within the bearing.
