Embodiment Construction

[0026] figure 1 Correspondingly, a rolling bearing 1 is shown, which is designed here as a tapered roller bearing. The rolling bearing 1 comprises an outer bearing ring 3 and an inner bearing ring 5 into which several raceways 7a, 7b are introduced. A plurality of conical rolling elements 9 are arranged between the raceway 7a of the bearing inner ring 5 and the raceway 7b of the bearing outer ring 3, figure 1 Two of them can be seen in .

[0027] The tapered rollers 11 roll on the raceways 7a and 7b of the bearing rings 3 and 5 . In order to guide the rolling of the tapered rollers 11 on the raceways 7a, 7b, on the side of the raceway 7a of the bearing inner ring 5 (in the figure 1There is a large rib 13 on the structure. The ribs 13 extend radially outwards from the bearing inner ring 5 towards the bearing outer ring 3 . The bearing outer ring 3 is designed without ribs in this exemplary embodiment. Furthermore, the bearing inner ring 5 has no rib on its axially opposit...

Abstract

The invention relates to an anti-friction bearing (1) having a bearing outer ring (3), a bearing inner ring (5) and a plurality of rolling bodies (9) which are arranged between the bearing outer ring (3) and the bearing inner ring (5), are held at predefined spacings from one another by a bearing cage (15) and roll on raceways (7a, 7b) of the bearing rings (3, 5), of which at least one raceway is delimited by a rim (13), wherein the bearing cage (15) has two cage side rings (17a, 17b) and a plurality of cage webs (19) which connect the cage side rings (17a, 17b), and in which at least one guiding and holding element (23) extends from the bearing cage (15) towards the rim (13) and engages axially behind the rim (13). According to the invention, at least one opening (27) is formed in one of the cage side rings (17b), in which opening (27) the at least one guiding and holding element (23) is fastened. As an alternative to this, in an anti-friction bearing (1') according to the invention, an additional ring (33) is fastened to one of the cage side rings (17b), with which additional ring (33) the guiding and holding element (23) is formed in one piece. The proposed construction avoids the risk that the guiding and holding element (23) is damaged during the assembly of the anti-friction bearing (1).

Description

technical field [0001] The invention relates to a rolling bearing with an outer bearing ring, an inner bearing ring and a plurality of rolling bodies, the rolling bodies being arranged between the bearing outer ring and the bearing inner ring, held at a predetermined distance from each other by a bearing cage and Rolling on raceways of bearing rings, at least one of these raceways being delimited by ribs, wherein the bearing cage has two cage side rings and a plurality of cage webs connecting the cage side rings, and wherein , at least one guide and retaining element extends from the bearing cage towards the rib and engages against the rib in the axial direction. Background technique [0002] Rolling bearings of the type described here are known per se. During its assembly, the problem arises that after the bearing cage holding the rolling elements has been moved onto the bearing inner ring, these components must not fall off each other and the rolling elements remain in th...
