  • Publication number: 20130039611
    Abstract: The invention relates to a sealing assembly for a rolling bearing having two mutually concentric rings spaced apart from each other by a fully circumferential gap in which one or more rows of revolving rolling elements are disposed, such that the two rings are rotatable relative to each other about their common axis, wherein the gap is sealed in the region of at least one of its two mouths, and wherein provided in the region of a gap seal are at least two seal rings, each having at least one sealing lip and an anchoring region on a surface region of the particular seal ring that faces away from the sealing lip, the seal rings being fixed to the same rolling bearing ring, whereas their respective sealing lips bear against the other rolling bearing ring, specifically against surface regions having identical or similar cross section.

    Abstract: A ball bearing having first and second races and, disposed in a gap between the two races, a row of balls of radius RK that roll along facing tracks of the two races, wherein centers of the balls move on a circular path surrounded by a torus circumscribing all the balls of the row and having the toroidal radius RK, a toroidal angle coordinate ?, and a poloidal angle coordinate ?, wherein each track has with each ball two nearly punctiform contact areas P1, P2; P3 P4 at respective contact angles ?P1, ?P2; ?P3 and ?P4, wherein the cross section of the track in the region of the contact points P1 . . . P4 has a finite transverse radius of curvature RL1 . . . RL4, with RLv>RK, and wherein in the vicinity of a contact point P1 . . . P4 the transverse radius of curvature (RL) is a continuous and differentiable function of the poloidal angle coordinate ?: RL=RL(?) that increases outward from the respective contact point P1 . . . P4 in both poloidal directions: RL(?)?RL(?Pv).

  • Publication number: 20120220418
    Abstract: The invention is directed to a Wolfrom-type, webless planetary gear set, comprised of two coaxial housing parts which are rotatable opposite each other with one each internal toothing on the applicable inner side, a toothed sun gear as well as several toothed planetary gears, which roll between the sun gear and the internal sets of teeth and are arranged in a floating manner. In other words, without further guidance on a planetary gear carrier or similar with a bearing arrangement between the two housing parts whose bearing bodies circulate around the paths which are located radially outside at least one internal toothing.

  • Publication number: 20110255815
    Abstract: The invention is directed to a device for rotatably coupling two coaxial connecting elements, at least one of which is configured as a circular ring, and each of which has at least one annular surface that faces the corresponding surface of the respective other connecting element but is spaced apart therefrom by a gap, such that they are rotatable in opposite directions about an imaginary axis (axis of rotation) at the center of the annular connecting element and approximately perpendicular to the ring plane, wherein disposed in the gap between the two connecting elements is a rotary joint, configured as a single- or multi-row rolling bearing, for absorbing axial and radial loads and tilting moments, wherein at least one annular connecting element comprises, on its surface facing the gap, a continuously circumferential, planar shoulder having an oblong or elongated cross section and extending away from the gap to a freely terminating, peripheral circumferential edge.
