A device for producing a spur toothing includes a tool holder arranged for rotational drive about a drive axis and longitudinal displacement along the drive axis, and a tool arranged on the tool holder. The tool includes an end face, a mating toothing disposed on the end face and arranged for forming a spur toothing on a workpiece, and a longitudinal axis arranged at an angle to the drive axis such that the longitudinal axis meets the drive axis at a wobble point. The mating toothing has a tooth base plane and the wobble point is disposed on the drive axis in front of or behind the tooth base plane such that, through rotary drive and longitudinal displacement of the tool holder with the associated wobbling rolling of the tool on the workpiece, the spur toothing formed by the mating toothing has a number of teeth that is unequal to a number of teeth of the mating toothing.

A bearing assembly includes an inner bearing ring, an outer bearing ring and rolling bodies located between the inner bearing ring and the outer bearing ring. A gap is defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring. The radially inner surface of the outer bearing ring includes a first radial surface portion that is offset a greater distance from a center of the bearing than a second radial surface portion. The first and second radial surface portions are connected by a sloped surface. A sealing arrangement located in the gap. The sealing arrangement includes a first annular body including an elastomeric sealing protrusion to contact the sloped surface of the outer bearing ring.

Wheel bearing

A seal arrangement for a wheel bearing having first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which bearing parts rolling elements are guided. The sealing arrangement includes: a carrier element, which is connected to the first bearing part and an elastic element is provided on the carrier element. The elastic element has at least one sealing lip, and the carrier element has a fastening section, which is connected to the first bearing part. A stop part is fastened to the second bearing part with which the at least one sealing lip is in rubbing contact. The wheel bearing flange has an axial projection at least partially surrounds an axial projection of the first bearing part, and an inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.

A sealing arrangement comprising a carrier element connecting to a first bearing part, wherein the carrier element further includes an elastic element that includes a sealing lip, and a cavity between the first bearing part and a second bearing part, wherein the cavity is delimited by the carrier element, wherein the carrier element includes at least one aperture at a radial level of the cavity and the at least one aperture is sealed by a diaphragm connected to the carrier element, wherein at least one protective lip is provided on an opposite side of the diaphragm, and wherein the at least one protective lip is formed at the elastic element.

Sealing arrangement of a wheel bearing

A sealing arrangement for a wheel bearing having a first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which rolling elements are guided, wherein the sealing arrangement has a carrier element which is connected to the first bearing part and wherein a resilient element is provided on the carrier element, wherein the resilient element has at least one sealing lip, and the carrier element has a fastening portion which is connected to an outer circumference of the first bearing part, wherein a sealing ring which forms a seal for the fastening portion is formed on the resilient element, wherein the sealing ring has a cylindrical circumferential surface which abuts the external circumference of the first bearing part.

A sealing arrangement for a wheel bearing having a first component against a second component which is rotatable relative thereto, the sealing arrangement having a first seal arranged on the first component and a second seal arranged on the second component, the first seal has at least one opening for the passage of air at least in a sealing chamber formed spatially between the two seals, and a fabric element is provided to at least partially expand upon contact with water and thereby to seal the at least one opening.

Sealing arrangement

A method for producing a composite rolling bearing () having a bearing flange () and at least one rolling bearing () held on the bearing flange () by an inner ring (). In order to be able to fix the inner ring () on the bearing flange () with axial preloading without expansion, the inner ring () is acted upon by a holding-down device () that radially holds down the inner ring () and is preloaded against the inner ring () by a regulated axial force (F), and, by way of an advancing cone () introduced radially on the inside axially into the bearing flange (), material () present on the bearing flange () is displaced radially towards the outside into a recessed formation () in the inner ring ().

Method for producing a composite rolling bearing

Wheel bearing unit with a wheel hub, wherein the wheel hub has an integrally formed wheel flange on one end thereof and an inner ring that is rotatable together with the wheel hub, wherein the inner ring is fastened on the wheel hub through the use of a rolling rivet connection in order to pre-tension a row of rolling elements in relation to an outer ring, and with an encoder provided on the inner ring and extending radially towards the outer ring, and with a protective cover fixed on the outer ring in order to close and seal annular openings formed between the outer ring and the wheel hub, and wherein a cylindrical section of the protective cover is pressed in and wherein a bottom section extends inwardly from the cylindrical section in a radial direction in order to cover an inner-side end of the wheel hub, wherein the cylindrical section is joined with a substance bond to the outer ring and wherein the substance-bond connection is produced through the use of a hardening fluid and wherein the fluid is held in a filling reservoir provided between the cylindrical section and the outer ring.

Wheel bearing unit

A wheel bearing arrangement of a vehicle axle is disclosed. The wheel bearing arrangement includes a wheel bearing, which contains at least two rolling element rows, for supporting a wheel hub which can be driven by a drive element. The rolling elements of the wheel bearing are guided in races of a stationary outer ring, the rotating wheel hub, and a separate inner ring which is allocated to the wheel hub. In the assembled state, the wheel hub of the wheel bearing arrangement and the drive element are operatively connected via gearing. The inner ring has a radially stepped inner contour, the inner contour having two diameters which differ from one another, and are received in a complementarily designed receiving area of the wheel hub. The position of the inner ring is fixed on the end face by a rolling riveted collar of the wheel hub.

A bearing seal () of a rolling bearing configured as a wheel bearing () that is connected between a first rotationally rigid bearing part () and a second bearing part () that is integral with a wheel bearing flange (), between which rolling bodies () are guided. The bearing seal () includes a splash plate () configured as a preseal, which is supported on an axially and radially oriented contour () of the second bearing part (), and together with the wheel bearing flange (), axially defines a catch channel (). A seal fitting () is fixed to the first bearing part () by a reinforcement (), wherein the reinforcement () is enclosed by an elastic sealing material (), at least in some areas, from which sealing lips () are formed, which are grindingly or non-grindingly associated with the splash plate (). Between the splash plate (), which abuts, in a line or surface contact, the radially oriented wheel bearing flange () via a support zone (), and the sealing fitting (), a sealing labyrinth () is provided. By way of a resiliently flexible fastening section (), the splash plate () is pressed onto the cylindrical contour () of the second bearing part () and is pre-stressed in an end position.
