  • Patent number: 9169874
    Abstract: A sealing arrangement comprising a one-piece, peripheral, elastomeric sealing material for sealing a sealing space, the material containing a bearing-side sealing region and inserted between at least one outer rotatable bearing component and, mutually rotatable about the same center axis, at least one inner rotatable bearing component of a rotary joint, wherein the sealing arrangement is form-lockingly and force-lockingly connected in a detachable and replaceable manner to a structure, namely (I) to a plunge cut in a surface parallel to a horizontal outer surface of one of the inner and outer rotatable bearing components, and (II) to a projecting material protrusion with a bottom surface which is disposed on the bearing side of this material protrusion, as an integral part of the inner or outer rotatable bearing component.

  • Publication number: 20130279834
    Abstract: The invention relates to a sealing arrangement made of a preferably integral peripheral rubber-like sealing material for sealing the sealing space for use in a rotary connection, wherein the sealing space is confined by a sealing region (17) on the bearing side and the sealing arrangement is used between at least one outer ring (or outer rotatable bearing component) (7) and at least one inner ring (or inner rotatable bearing component) (8) rotatable against one another about the same central axis, wherein the sealing arrangement is not irretrievably fixed in a groove but is connected by positive and non-positive engagement, so as to be releasable and replaceable again, to a recess (2) introduced on a surface parallel to the horizontal outer surface (20; 21) of the rotatable bearing component.

  • Publication number: 20130234403
    Abstract: Assembly for sealing a rotary joint, comprising first and second annular parts (2) arranged concentrically, one part being rotatably arranged relative to the other, at least one circumferential gap (18) between the first annular part (2) and the second annular part (3); wherein the first annular part (2) comprises a convex curvature (8), and the second annular part (3) comprises a convex curvature (9); a sealing element (4) received in the gap (18) and disposed sealingly against the first and second annular parts (2); the sealing element (4) comprising sealing lip pairs (21), each pair being associated with one convex curvature (8, 9), such that two sealing lips (21) embrace each convex profile curvature (8, 9) sealingly thereagainst; wherein the sealing element (4) exhibits axial symmetry relative to one axis of symmetry (6), and one axis of symmetry is inclined relative to a vertical axis (13); and the convex profile curvatures (8, 9) have points protruding toward the sealing element (4), and the points lie

  • Patent number: 8449201
    Abstract: The invention relates to an element (10) for sealing two parts (2, 3) that can be rotated in relation to one another. Said element comprises at least one first sealing ring (11) consisting of a permanently elastic material, which is fixed to one of the two rotatable parts and comprises at least one sealing lip (21) and at least one second sealing ring (12), which is fixed to the other rotatable part and comprises a strip (19) consisting of another material that runs along its periphery. At least one sealing lip of the first sealing ring lies against said strip.
