(54) AXIAL THRUST ROLLING BEARING (71) We, SKF KUGELLAGERFABRIKEN GESELLSCHAFT MIT BESCHRANKTER HAFT UNG, a German Body Corporate, of Ernst Sachs-Strasse 2-8, 8720 Schweinfurt 2, German Federal Republic, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention concerns an axial thrust rolling bearing.
According to the invention an axial thrust rolling bearing comprises two rings, a plurality of rolling elements arranged to roll on race surfaces of the rings, and a cage locating the rolling elements circumferentially, the cage having an annular portion extending circumferentially radially inside or outside of the rolling elements, each ring having a surface facing a surface of the annular portion of the cage to provide two pairs of facing surfaces, one in each pair being a surface of a ring and the other of each pair being a surface of the cage, the surfaces of each pair of facing surfaces being parallel with one another, one of the pairs of facing surfaces being in contact with one another and the other pair being axially spaced from one another.
The bearing may be a self-aligning roller bearing and one of the rings may have an annular edge disposed on the radially opposite side of the rollers to the annular portion of the cage, one axial end of each of the rollers bearing against the dge.
Each ring may have an annular flange providing the said facing surface of that ring and each of the facing surfaces may be a radial plane.
The cage may be a solid cage and of a material having a lower coefficient of friction than that of the rings.
An embodiment of the invention will now be described by way of example and with reference to the accompanying drawing which is an axial section of part of a self-aligning roller bearing. The bearing comprises two rings 1 and 2, a plurality of spherical rollers 3 arranged to roll of race surfaces 13 and 14 of the rings, and a cage 4 locating the rollers circumferentially.
The cage 4 has an annular portion 5 extending circumferentially radially inside of the rollers 3. Each ring 1 and 2 has an annular flange 8 and 11 respectively. Flange 8 provides a surface 9 facing a surface 7 of the annular portion 5 and flange 11 provides a surface 12 facing a surface 6 of the annular portion 5.
The surfaces of each pair, 6 and 12, 7 and 9, are parallel with one another and each surface is a radial plane. Surfaces 6 and 12 of one pair are axially spaced at 15 from one another, and surfaces 7 and 9 of the other pair are in contact with one another.
Ring 1 has an annular edge 10 disposed on the radially outside of the rollers 3, and one axial end of each of the rollers bears against the edge.
The cage 4 is preferably solid and of a material e.g. forged bronze having a lower coefficient of friction than that of the rings 1 and 2.
When a relatively heavy axial load is applied to ring 2, the race surfaces 13 and 14 of the rings and the rollers 3 may be worn heavily, e.g. because of poor lubrication.
Consequently the total or overall height or axial distance of the bearing decreases and the axial distance of the gap 15 also decreases until surface 12 of flange 11 contacts surface 6 of annular portion 5. The resulting plain bearing so formed, having surfaces 6 and 12, acts as an emergency bearing and ensures that the rolling bearing continues to run for a limited period without causing appreciable damage until the complete bearing can be replaced.
WHAT WE CLAIM IS:- 1. An axial thrust rolling bearing comprising two rings, a plurality of rolling elements arranged to roll on race surfaces of the rings, and a cage locating the rolling elements circumferentially, the cage having an annular portion extending circumferentially, radially inside or outside of the rolling elements, each ring having a surface facing a surface of the annular portion of the cage to provide two pairs of facing surfaces, one

3. A bearing as claimed in claim 1 or 2 wherein each ring has an annular flange providing the said facing surface of that ring.
4. A bearing as claimed in any one of claims 1 to 3 wherein each of the facing surfaces is a radial plane.
