The invention relates to a spur toothing on at least one coupling element for transmitting torques about a rotational axis, said spur toothing axially engaging with a corresponding mating cutting. The face cutting is provided with teeth from a material of the coupling element that has been plastically shaped in an at least partially noncutting manner.

Spur toothing on a coupling element for transmitting torques

The invention relates to a spur toothing on at least one coupling element for transmitting torques about a rotational axis, said spur toothing axially engaging with a corresponding mating cutting. The face cutting is provided with teeth from a material of the coupling element that has been plastically shaped in an at least partially non-cutting manner.

A ball roller bearing, which has an outer and inner bearing ring with a groove-shaped raceways and ball rollers, which roll between the bearing rings in the raceways. The rollers are held at distances from each other in the circumferential direction by a bearing cage and which have a width that is dimensioned larger than the radial distance between the inside and the outside of the bearing rings. The raceways are divided into two segments by an axially centered annular groove such that a first ball roller rolls on two first diagonally opposed track segments and a second ball roller rolls on two second diagonally opposed track segments of the bearing rings. Both bearing rings are single-piece components, and the bearing cage is formed by two identical double prong-type cages acting independently of each other. The bearing is filled with the ball rollers by an axial tilt cam assembly method.

Ball roller bearing, in particular for absorbing combined radial and axial loads

A hearing arrangement which has a double-row rolling-body bearing, in particular an angular ball bearing for a turbocharger. The rolling-body bearing has at least one outer ring and at least one inner ring between which an intermediate space for two rows of rolling bodies is formed. For reliable and disruption-free lubrication, the rolling-body bearing has a central feed opening formed on the outer ring, and at least one outlet opening, lying opposite the central feed opening, on the inner ring for a lubricant. In the vicinity of each of the rows of rolling bodies, at least one feed opening is provided on the inner ring for feeding the lubricant to the rolling bodies so that the lubricant is injected via the inner ring, and the centrifugal force during the operation of the bearing is utilized.

A face spline of a toothed rim running in a circumferential direction around a rotation axis on a wheel-bearing arrangement for a driven wheel hub. The face spline is provided for play-free engagement with the counter-spline, facing the face spline and the teeth of the face spline have a wedge-like embodiment such that the geometrical lines of the face spline meet centrally at a common point on the rotation axis and the teeth thus run in the radial direction on the rotation axis.

Face spline for a driven wheel hub

The bearing arrangement for a connection of a wheel hub to a rotating joint. A face of an axle stub of the wheel huh with a spur gearing element is non-rotatably connected to a corresponding spur gearing element of a joint body of the rotating joint. The spur gearing elements are disposed at least partially radially and axially beneath the roller bearing. The inner bearing ring is connected to a means for the axial tolerance compensation between the inner hearing ring and the counter-surface of the joint body.

One inner raceway is formed on the outer part and one outer raceway is formed on the inner part for the rolling bodies of each row. The wheel hub has internal toothing, which projects radially inwards in the direction of the rotational axis, for engaging external toothing on a drive pin. The internal toothing of the hub is rotationally fixedly coupled to the outer raceway. The ratio of the diameter dof a tip circle of the internal toothing to the bearing width bof the outer part is greater than 0.9.

A wheel bearing arrangement which has at least two rows of rolling bodies for mounting a wheel hub which can be driven with the wheel bearing arrangement by a drive element. The wheel hub is connected to the drive element, and the wheel hub and the drive element engage positively into one another via a pair of mutually corresponding spur toothings. In the wheel bearing arrangement, a value of greater than three is obtained for a ratio of the diameter of a toothing reference circle of the spur toothing in the wheel bearing arrangement to the rolling body row spacing of the at least two rows of rolling bodies.

The wheel bearing joint unit having an inner ring that sits on a hub of the wheel bearing joint unit. The inner ring is axially retained on the hub using a collar that is formed from the hub. The collar is provided with a toothing which meshes with a corresponding opposite toothing on a joint part. The toothing and the opposite toothing are braced against each other by a screw which rests on the hub and engages into a thread on the joint part. The joint has two axial projections, one which has the toothing to engage the toothing on the collar and another with the threading to engage the screw. These two projections are spaced apart by a groove to provide flexibility.
