Abstract

A radial rolling element bearing ( 1 ) formed of a cylindrical outer ring ( 3 ) that is inserted into a housing ( 2 ), and a rolling element cage ( 4 ) arranged in said outer ring and formed by a plurality of roller-shaped rolling bodies ( 6 ) which are inserted into a bearing cage ( 5 ) and held thereby, equidistantly, in a circumferential direction, and roll on an outer raceway ( 8 ) formed by the inner lateral surface ( 7 ) of the outer ring, and on an inner raceway ( 11 ) formed by the outer lateral surface ( 9 ) of a shaft ( 10 ) to be mounted or a smooth cylindrical inner ring pushed onto said shaft. The roller race is axially guided by two separate flanged disks ( 14, 15 ) which lie against the axial sides ( 12, 13 ) of the outer ring and are axially secured, together with the outer ring, by securing elements which engage in recesses ( 16, 17 ) in the housing. According to the invention, this radial rolling element bearing is characterized in that said flanged disks include a right-angled profiled cross-section that has a horizontal securing leg ( 18, 20 ) and a vertical flanged leg ( 19, 21 ) and, by pressing their horizontal securing legs onto two peripheral stepped shoulders ( 22, 23 ) in the edge regions of the outer lateral surface ( 24 ) of the outer ring, are secured thereto; and in that the securing elements which engage in recesses in the housing for the purpose of axially securing said rolling element bearing are designed as spring elements ( 25, 26 ) integrated into the securing legs of the flanged disks.

First claim

The invention claimed is:

1. A radial rolling element bearing, comprising: a cylindrical outer ring inserted in a housing and a rolling element cage arranged in said outer ring formed by a plurality of roller-shaped rolling bodies inserted in a bearing cage and held by said cage at equal intervals in a circumferential direction and roll on an outer raceway formed by an inner lateral surface of the outer ring and on an inner raceway formed by an outer lateral surface of a shaft to be supported or of a smooth cylindrical inner ring slid onto the shaft, two separate flanged disks that contact axial sides of the outer ring provide axial guidance of the rolling element cage and are fixed axially together with the outer ring by securing elements engaging in recesses in the housing, the flanged disks have a right-angled profile cross section with a horizontal securing leg and a vertical flanged leg and are fixed on the outer ring by pressing of said respective horizontal securing legs on two peripheral step shoulders in edge regions of an outer lateral surface of the outer ring and the securing elements that engage in the recesses in the housing are constructed for axial fixing of the rolling element bearing as spring elements integrated in the securing leg of the flanged disks.

2. The radial rolling element bearing according to claim 1 , wherein the horizontal securing legs of the flanged disks are fixed on the outer ring by several centering beads that are formed in circumferential surfaces distributed equally over a periphery of the outer ring and are also directed radially inward on the peripheral step shoulders in the edge areas of the outer lateral surface of the outer ring.

3. The radial rolling element bearing according to claim 2 , wherein a depth of the step shoulders on the outer ring corresponds to a material thickness of the securing legs plus a depth of the centering beads, so that the circumferential surfaces of the securing legs of the flanged disks and the outer lateral surface of the outer ring are arranged in a horizontal plane.

4. The radial rolling element bearing according to claim 3 , wherein the spring elements integrated in the securing legs are constructed for axial fixing of the rolling element bearing as elastic locking tabs that are formed from the securing legs and have a bulge or angled section directed radially outward on ends of each of the securing legs.

5. The radial rolling element bearing according to claim 4 , wherein gaps created by the centering beads in the securing legs between the securing legs and the step shoulders on the outer ring are constructed as spring deflection spaces for the locking tabs during bearing installation and as bonding gaps for connecting the flanged disks to the outer ring.

6. The radial rolling element bearing according to claim 5 , wherein the bonding gaps interrupted by the spring deflection spaces are filled completely with adhesive.

7. The radial rolling element of claim 6 , wherein the adhesive is selected from one of a two-component adhesive or an anaerobic adhesion.

8. The radially rolling element of claim 6 , wherein the adhesive is mixed with a sphere-shaped filler material.
