(54) AXIAL THRUST ROLLING BEARING
(71) We, SKF KUGELLAGERFABRIKEN
GESELLSCHAFT MIT BESCHRANKTER
HAFTUNG, 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 is concerned with an axial thrust rolling bearing.
The invention in one aspect provides an axial thrust rolling bearing having two race rings and an annular series of rolling elements arranged to roll on the raceway surfaces of and between the race rings, the race rings being capable of at least limited radial movement with respect to each other, one race ring having a raceway surface which is at least in part a radial planar surface extending all the way round the race ring and an annular portion adjacent to the planar surface and extending towards the other race ring, there being between the planar surface and the annular portion, a portion which is curved and has a radius of curvature no less than that of the associated portion of the rolling elements.
With the rolling elements rolling on the raceways, the amount of radial movement of the race rings with respect to each other may be limited by the construction of the race rings.
The said other race ring has a raceway surface which may be at least in part a radial planar surface extending all the way round the race ring and may have an annular portion adjacent to the planar surface and extending towards the said one race ring.
The rolling elements may be located by the annular portion of the said one race ring and the annular portion of the said other race ring.
The invention in another aspect provides a clutch release bearing assembly having a sleeve and an axial thrust bearing according to any one of the immediately preceding four paragraphs disposed around the sleeve, one of the race rings being fixed to the sleeve and the other of the race rings being radially movable with respect to the sleeve.
The movable race ring may not contact the sleeve with the rolling elements rolling on the raceways.
The rolling elements may be balls, the said other race ring may have a raceway groove which is part of a circle in axial section, and, with the race rings and the annular series of balls coaxial, the radial distance between the radially outer surface of the sleeve and the radially innermost portion of the movable race ring may be greater than the radial distance between an edge of the annular portion of the said one race ring, which edge is adjacent to the planar surface, and the radially innermost point of intersection of a plane extending transverse to the bearing axis and through the said edge with the balls.
Two embodiments of the invention will now be described by way of example with reference to the accompanying drawings of which:
Figure 1 is an axial section of a clutch release bearing assembly, and
Figure 2 is an axial section of an axial thrust bearing.
Referring to Figure 1, the clutch release bearing assembly shown has an axial thrust bearing comprising two race rings 1 and 4 and an annular series of rolling elements 10.
The axial thrust bearing is disposed around a sleeve 3 with race ring 1 mounted on and fixed to an enlarged portion 2 and abutting an annular flange of the sleeve 3. Race ring 4 is located in an annular metal casing 5, which casing has a radially outwardly extending annular flange 7 for engagement with the ends of the fingers 6 of a clutch diaphragm spring. An annular disc 8 extends from flange 7 radially inwardly to the sleeve flange.
Race ring 1 has a raceway surface 12 which is a radial planar surface extending all the way round the ring 1. Adjacent to the planar surface, and radially each side, are two annular portions 13 and 14 which extend towards ring 4. There is a portion 11 between each annular portion 13, 14 and the planar surface 12 which is curved and has a radius of curvature no less than that of the balls 10. Race ring 4 has a raceway surface comprising an annular groove 9 which is part of a circle in axial section.
The race rings 1 and 4 are movable radially with respect to each other, the amount of radial movement, with the balls
10 rolling on the raceways 12 and 19, being limited by the construction of the race rings
1 and 4. The embodiment shows the race rings centrally disposed with respect to each
other and being movable a distance "a", which is the radial distance between inner edge 15 of the raceway of ring 1 and
the radially innermost point of intersection
of a plane extending transverse to the bear
ing axis and through edge 15 with ball 10.
Distance "e" is the radial distance between
radially outer surface 17 of the sleeve 3 and
the inner surface 16 of the ring 4. Distance
"a" is less than distance "e" so that the
ring 4 does not contact the sleeve 3.
The embodiment shown in Figure 2 has
two race rings 1 and 4. Race ring 1 has a
raceway surface 12, which is a radial planar
surface extending all the way round the
ring, and an annular portion 14 radially in
wardly of and adjacent to the planar
surface and extending towards race ring 4.
A portion 11 between annular portion 14
and the planar surface is curved and has a
radius of curvature no less than that of the
balls.
Race ring 4 has a raceway surface 20,
which is a radial planar surface extending
all the way round the ring, and an annular
portion 18 radially outwardly of and
adjacent to the planar surface and extend
ing towards race ring 1. A portion 19
between annular portion 18 and the planar
surface is curved and has a radius of
curvature no less than that of the balls.
The two annular portions 14 and 18 of
this embodiment thus locate the rolling
elements or balls. Of course the relative
dispositions of the annular portions 14 and
18 may be reversed with 18 being the
radially inner and 14 being the radially
outer of the portions.
In the embodiments shown and de
scribed, the rolling elements are balls. How
ever, spherical ended cylindrical rollers can
be used, in which case the radius of curvature of portions 11 and 19 is no less than that of the associated portion of the rolling elements, i.e. the spherical ends of the rollers.
Various combinations of race rings are possible, the construction of which limits the amount of radial movement of the race rings of an axial thrust bearing with respect to each other. For example race ring 1 of
Figure 1 with race ring 4 of Figure 2, or race ring 1 of Figure 2 with race ring 4 of
Figure 1.

Claims (9)
1 and 4. The embodiment shows the race rings centrally disposed with respect to each
other and being movable a distance "a", which is the radial distance between inner edge 15 of the raceway of ring 1 and
the radially innermost point of intersection
of a plane extending transverse to the bear
ing axis and through edge 15 with ball 10.
Distance "e" is the radial distance between
radially outer surface 17 of the sleeve 3 and
the inner surface 16 of the ring 4. Distance
"a" is less than distance "e" so that the
ring 4 does not contact the sleeve 3.
The embodiment shown in Figure 2 has
two race rings 1 and 4. Race ring 1 has a
raceway surface 12, which is a radial planar
surface extending all the way round the
ring, and an annular portion 14 radially in
wardly of and adjacent to the planar
surface and extending towards race ring 4.
A portion 11 between annular portion 14
and the planar surface is curved and has a
radius of curvature no less than that of the
balls.
Race ring 4 has a raceway surface 20,
which is a radial planar surface extending
all the way round the ring, and an annular
portion 18 radially outwardly of and
adjacent to the planar surface and extend
ing towards race ring 1. A portion 19
between annular portion 18 and the planar
surface is curved and has a radius of
curvature no less than that of the balls.
The two annular portions 14 and 18 of
this embodiment thus locate the rolling

dispositions of the annular portions 14 and
18 may be reversed with 18 being the
radially inner and 14 being the radially
outer of the portions.
In the embodiments shown and de
scribed, the rolling elements are balls. How
ever, spherical ended cylindrical rollers can
be used, in which case the radius of curvature of portions 11 and 19 is no less than that of the associated portion of the rolling elements, i.e. the spherical ends of the rollers.
Various combinations of race rings are possible, the construction of which limits the amount of radial movement of the race rings of an axial thrust bearing with respect to each other. For example race ring 1 of
Figure 1 with race ring 4 of Figure 2, or race ring 1 of Figure 2 with race ring 4 of
Figure 1.
