  • Patent number: 9732799
    Abstract: An axial bearing arrangement formed substantially of two rotating carrier components (1, 2) with circular ring-shaped end faces (3, 4) and an axial anti-friction bearing (5) arranged between the carrier components (1, 2). This axial anti-friction bearing (5) has a first ring-shaped angle disk (6), which rests on the end face (3) of the first carrier component (1) and which is made from a thin steel sheet, and a second ring shaped angle disk (7), which rests on the end face (4) of the second carrier component (2) and a needle cage (10), which rolls between the axial inner sides (8, 9) of the angle disks (6, 7) and which is formed from a plurality of bearing needles (12) arranged adjacent to one another and held at equal distances to one another by a bearing cage (11), and is lubricated and cooled by a lubricant flow (13) emitted by a shaft which passes centrally through the axial anti-friction bearing (5).

  • Publication number: 20160265592
    Abstract: The invention relates to an axial cage for cylindrical rolling elements, which is formed substantially of a thin-walled annular disc with a profiled cross section, which is formed by an inner radial rim shaped on the inner edge of the annular disc, by an outer radial rim shaped on the outer edge of the annular disc, and by a center beading connected to the radial rims via axial inner and outer intermediate profile sections. A number of uniformly spaced, rectangular cage pockets are removed from the beading and the adjacent intermediate profile sections, between which cage pockets an identical number of pocket webs are formed connecting the rims with each other, by which the cylindrical rolling elements are held in the cage pockets at a uniform distance to each other and guided in the circumferential direction.

  • Patent number: 9404537
    Abstract: an axial cage (1) for cylindrical rolling bodies which substantially is formed of a thin-walled washer (2) with a W-shaped profile, the individual profile legs of which are formed by an inner radial rim (3) formed on the inner edge of the washer (2), an outer radial rim (4) formed on the outer edge of the washer (2) and a U-shaped center crimp (7) connected by way of inner and outer axial profile sections (5, 6) to the radial rims (3, 4) and having the same radial extent as the rims (3, 4). A number of evenly spaced rectangular cage pockets (8) are cut from the central crimp (7) and the adjacent axial profile sections (5, 6), between which pockets an equal number of pocket webs (9) are formed connecting the rims (3, 4) with one another, by which webs the cylindrical rolling bodies (10) are retained in the cage pockets (8) at uniform distances from one another and are also guided in the circumferential direction.

  • Patent number: 8926191
    Abstract: An axial cage for cylindrical rolling elements includes an annular disc, the disc having a W-shaped profile cross-section and including a radially inner rim, a radially outer rim, and a U-shaped bead connected via straight profile sections to the rims. Rectangular cage pockets are worked out of the bead and the adjoining straight sections, between which are pocket webs that connect the rims to one another and hold cylindrical rolling elements in the cage pockets. The outer rim has a crown cap-like overall shape such that it includes, in the region of each cage pocket, a constriction that extends axially into the cage pocket and is in supporting contact with an end face of the rolling elements, and, in the region of each pocket web, a section corresponding to the outer diameter of the axial cage.

  • Patent number: 8821028
    Abstract: An axial bearing assembly which essentially is formed of two axial rolling bearings (1, 2) between which a circular ring-shaped carrier component (3) is arranged. Each of the axial rolling bearings (1, 2) has a first ring-shaped bearing disk (6, 7) seated against one of the axial sides (4, 5) of the carrier component (3) and a second ring-shaped bearing disk (8, 9) for fastening to additional components of the surrounding construction which are arranged axially on both sides of the carrier component (3) and which each consist of a thin steel plate. A plurality of rolling elements (14, 15) arranged next to each other additionally roll between the axial inner sides (10, 11 and 12, 13) of the bearing discs (6, 7, 8, 9) and are held at a uniform spacing from each other by a respective bearing cage (16, 17) and together therewith form a needle roller and cage assembly (18, 19).

  • Publication number: 20130089286
    Abstract: The invention relates to an axial cage (1) for cylindrical rolling elements, which consists substantially of a thin-walled annular disc (2) having a W-shaped profile cross-section, the individual profile limbs of which are formed by a radially inner rim (3) that is integrally molded on the inner edge of the annular disc (2), by a radially outer rim (4) that is integrally molded on the outer edge of the annular disc (2) and by a U-shaped bead (7) which is connected via straight profile sections (5, 6) to the rims (3, 4) and has the same radial extension as the rims (3, 4). A plurality of rectangular cage pockets (8) arranged at uniform distances apart from each other is worked out of the bead (7) and the adjoining straight sections (5, 6). Between said cage pockets there are pocket webs (9) that connect the rims (3, 4) to one another, wherein said pocket webs hold the cylindrical rolling elements (10) in the cage pockets (8) and guide same in the circumferential direction.

  • Publication number: 20090317620
    Abstract: The invention relates to a furniture component (1) comprising a core (2), which is covered by a film (6) at least in the region of a narrow face (5; 11) and side surfaces (3, 4) of the core adjoining the same, and to a method for the production thereof. The aim of the invention is to enable the simple production of a smooth, stable and tight surface of the face of a furniture component covered with the film. This aim is achieved by a furniture component, wherein a smoothing layer (8; 12) for smoothing the surface of the face is provided between the face and the film, and by a method, wherein a smoothing material (8?; 12a, 12b, 12c) is applied to the face in order to form a smoothing layer, the film (6; 6?, 6?) is then applied to the face, and subsequently the film is applied to at least one first lateral surface adjoining the face and glued thereto.

  • Publication number: 20090285518
    Abstract: The invention relates to an axial rolling bearing having a cage which contains rolling bodies that are arranged between two running disks. The running disks each have a radial section that forms a raceway and an axially aligned collar which adjoins the raceway. The collars are aligned opposite to one another and overlap in the axial direction. The radially outer disk has a larger diameter than the radially inner running disk. According to the invention, the radial and the axial extent of the two collars of the running disks and the cage are coordinated with one another in such a way that, between them, a labyrinth seal, composed of a plurality of gaps, is formed, and the cage is guided on the collar of the radially inner running disk.
