Embodiment Construction

[0015] figure 1 A pinion shaft bearing device 1 according to the invention in the form of a bearing cartridge forming a preassembled unit is shown in . The pinion shaft bearing 1 comprises a one-piece outer ring 2 and an inner ring 3 consisting of (with respect to the mounting position) a ring section 4 close to the pinion and an inner ring section 5 remote from the pinion. The rolling element rows 9 , 10 , 11 guided in each case in the cages 6 , 7 , 8 roll between the outer ring 2 and the inner ring 3 (more precisely, the ring sections 4 , 5 ), the rolling elements being balls. That is to say that the pinion shaft bearing 1 is embodied as a three-row angular contact ball bearing.

[0016] The rolling element rows 9 , 10 , 11 run on corresponding raceways which are arranged on the outer ring 2 or the inner ring 3 . The outer ring 2 , which acts somewhat as an outer sleeve or outer housing, has corresponding raceways 12 , 13 , 14 , while corresponding raceways 15 , 16 , 17 ar...

Abstract

Provided is a pinion shaft supporting device in a multi-column angular contact ball bearing type. The pinion shaft supporting device is provided with an outer ring, an inner ring, and rolling elements arranged in a multi-column manner between the outer ring and the inner ring, wherein at least three rows of rolling element rows (9,10,11) are arranged, and at least two rows of the rolling element rows (9,10,11) have different contact angles ([alpha,beta]).

Description

technical field [0001] The invention relates to a pinion shaft bearing in the form of a multi-row angular contact ball bearing having an outer ring, an inner ring and rolling bodies arranged in rows between them. Background technique [0002] Pinion shaft bearings are widely used where the rotational movement of the shaft or the torque to be transmitted by the shaft is to be diverted or branched. A non-limiting example, however, is the branching of a motor vehicle drive shaft, for example in the region of the rear axle, in order to drive the rear wheels. The pinion shaft bearing is used there, for example, in a differential. [0003] Such pinion shaft bearings are realized either in the form of mounted tapered roller bearings or, according to the object of the invention, in the form of partially multi-row angular contact ball bearings. Here, each pinion shaft bearing comprises an outer ring, an inner ring and rolling bodies (here balls) arranged in rows between them. [0...
