Embodiment Construction

[0045] in figure 1 In this, an angular contact ball bearing 1 according to a preferred embodiment of the present invention is shown. The angular contact ball bearing 1 includes an outer ring 3 and an inner ring 5, and a ball 7 is arranged between the outer ring 3 and the inner ring 5. The ball 7 is held by the cage 9. The outer ring 3 is formed with a shoulder 13 facing inward in the radial direction, and a raceway 15 for the ball 7 is formed from the inner side of the shoulder 13. Similarly, on the inner ring 5, a shoulder 17 facing the radially outer side is formed, and starting from the inner side of the shoulder 17, a raceway 19 for the ball 7 is formed. Ball 7 is in contact area with radius r a Raceway 15 and radius r i The raceway 19 is close (osculateon). The close here is chosen to be significantly narrower than the angular contact ball bearings of known designs, thereby enabling better compression. In order to further optimize the compression, it is preferable to h...

Abstract

An angular contact ball bearing is specified comprising the following features: an outer rolling element comprising a first rolling surface; an inner rolling element comprising a second rolling surface; between these two rolling elements only one row of balls is arranged Rolling on the first rolling surface and the second rolling surface; the diameter D of the ball w , the outer diameter D of the outer rolling element and the inner diameter d of the inner rolling element are selected such that they have the following relationship to each other:

Description

Technical field [0001] The present invention relates to an angular contact ball bearing, which includes: an outer rolling element, which includes a first rolling surface; an inner rolling element, which includes a second rolling surface; between the two rolling elements, Only one row of balls is provided. The present invention also relates to a transmission assembly (or in particular a transmission assembly) for a motor vehicle, which includes a shaft including gear elements, and the shaft via at least two axially spaced single rows The rolling bearing is rotatably supported in a housing. Background technique [0002] Transmission assemblies are used in motor vehicles (for example in drivelines) in order to mechanically connect shafts driven by the motors of the motor vehicles to the wheels to be driven and transmit force accordingly. In known transmission assemblies, tapered roller bearings are generally used to support the shaft, and the tapered roller bearings are designed t...
