Ball Roller Bearings

Abstract

The invention relates to a ball roller bearing (1) having a plurality of ball rollers (4) arranged between an outer bearing ring (2) and an inner bearing ring (3), the ball rollers having two parallel The sides (5, 6) of these ball rollers, with their working surfaces (7) extending between the sides (5, 6), are machined to the inner side (8) of the outer bearing ring (2) and the inner bearing The outer side (9) of the ring (3) rolls in groove-shaped raceways (10, 11) and is held in respective cage pockets (12) of a bearing cage (13). The bearing cage (13) has two interconnected side rings (15, 16) and two cage ribs connected to these side rings for axially guiding the ball rollers (4 ) and guided contact with the sides (5, 6) of the ball rollers. According to the invention, the bearing cage (13) has a cylindrical base body (17) made of cold-deformable deep-drawn steel consisting of side rings (15, 16) and pocket webs (14), and The cage ribs are formed by two separate rib rings (18, 19) made of heat-treated carbon steel, which are force-locked and / or form-locked with the base body (17) ground connection.

Description

technical field [0001] The invention relates to a single row ball roller bearing according to claim 1 , which is characterized in the preamble, which can be used particularly advantageously, for example, as a fixed bearing for an input or output shaft of a motor vehicle gearbox. Background technique [0002] Ball roller bearings are rolling bearings with special rolling elements designed as ball rollers which, starting from a spherical basic shape, have two sides in each case which are flattened from this spherical basic shape and which are arranged parallel to each other. The working surfaces of the ball rollers are respectively arranged between the two sides. Such ball roller bearings are generally known as single-row, double-row, three-row or four-row radial ball roller bearings or angular contact ball roller bearings in very different embodiments and are also known due to the special shape of the rolling elements. A special design of the cage is required in order, on th...

Problems solved by technology

In addition, during the operation of the bearing, at the point of contact between the sides of the ball rollers and the ribs of the cage, there is increased wear on the ribs of the cage due to material extrusion and material stripping. Due to this wear, The ball rollers are no longer guided correctly in the axial direction on both sides and thus tend to lead to increased pivoting and to-and-fro movements

This oscillating and to-and-fro movement of the ball rollers then increases the friction and thus the bearing temperature, which is accompanied by increased bearing wear and ultimately leads to failure of the ball roller bearings
