Abstract
A bearing has spacers 40 (70 fig 4) to separate adjacent bearing balls 36 (14 fig 4) in a race defined by inner 54 (26 fig 1) and outer 64 (20 fig 1) bearing surfaces. The spacers may extend radially outwardly of a radially inwardly extending circumferential rib 42 of the outer bearing surface 64. With the spacers held completely between the inner and outer bearing surfaces (and not between the circumferential rib 42 and inner bearing surface 54), the outer bearing surface 64 can be kept large to accommodate for larger loads than with a bearing having a conventional cage for the balls. Preferably, the spacers compliment the shape of the balls and are seated on the inner and outer bearing surfaces. The spacers may be used in a single race ball bearing or the circumferential rib may define two outer bearing surfaces 64, 66 in a double race bearing.
Description
TITLE: Improvements in and relating to a bearing assembly
DESCRIPTION
This invention relates to a bearing assembly and in particular to a bearing assembly of the type designed to take axial and radial loading.
A known double track ball bearing of this type comprises an outer ring, an inner ring and two sets of balls disposed in axially spaced relation and separated by a circumferential rib extending inwardly from the outer ring and providing a bearing surface for each set of balls. The inner ring is formed by a cylindrical portion having a flange at each end thereof which provides a bearing surface for each of the two sets of balls. Thus each set of balls is disposed in a race defined between the bearing surfaces of the inner and outer rings.
By using what is known as a full ball complement si an uncaged set of balls, the bearing surfaces of the inner and outer rings can be extended radially outwardly and radially inwardly as the case may be so as to provide a substantial area of contact for the balls especially in connection with the ability to take axial loading. However, a disadvantage arises from the fact that adjacent balls rub together in that this generates friction and noise. The latter is particularly undesirable when the ball bearings are used on a long conveyor line.
In order to overcome the above problems it is known to provide a double sided cage comprising a ring which has apertures to receive the balls of each race and to space the balls of each race apart circumferentially to ensure that they do not contact one another. In order to accommodate the cage, the circumferential rib has to be cut away. This caged type ball bearing overcomes the aforementioned problems arising from adjacent balls contacting one another although it reduces the loading strength of the ball bearing since the area of bearing surface upon which the balls bear is reduced.
A prior art single track ball bearing is illustrated in figure 1 and comprises an outer ring 10, an inner ring 12 and a set of balls 14. The outer ring 10 is substantially "L" shaped in cross-section with the vertical circumferential limb 16 extending inwardly from the horizontal limb 18 and provides an outer bearing surface 20. The inner ring 12 is formed in one piece comprising a cylindrical flange 22 and a lower body 24 which reduces in diameter as it extends from the flange and provides an inner bearing surface 26 which is recessed in the surface of the inner ring. The balls 14 are disposed in a race defined between the inner and outer bearing surfaces.
The outer bearing surface wraps around the balls such that lateral movement of the balls in the direction of arrow 'A' is restricted ie in a direction perpendicular to a plane in which the balls lie. Similarly, the inner bearing surface also wraps around the balls. In order to assemble the ball bearing, the balls are located against the outer bearing surface and the inner ring is pushed into the outer ring, in the direction of arrow 'B', such that the sloping face of the lower body 24 bears against the balls.
The inner ring is formed of a suitable plastics material which is deformable so as to allow the lower body 24 to ride over the balls and there is a 'snap fit' engagement as the inner bearing surface wraps around the balls. In this ball bearing assembly it is not possible to locate a conventional cage and hence a full ball complement is used with the disadvantages mentioned above.
An aim of the present invention is to provide a bearing assembly which overcomes the above-mentioned problems.
In accordance with a first aspect of the present invention there is provided a bearing assembly comprising an outer ring having a radially inwardly directed circumferentially rib defining at least one bearing surface and having an edge radially inwardly thereof, an inner ring comprising in part a body portion spaced radially inwardly from said edge, a race defined between the inner and outer rings and the or each bearing surface of the circumferential rib and a set of balls disposed in the or each race, wherein said bearing assembly further comprises means associated with the or each race for separating circumferentially two or more adjacent balls and wherein at least part of said separator means occupies a position which is disposed radially outwardly beyond said edge.
It is preferred that said separator means spaces apart circumferentially each ball in a set from its adjacent ball. The separator means associated with each set of balls may be connected together or formed as an integral ring-like element. In a preferred embodiment of the invention, said separator means comprises individual spacers and each spacer may separate a pair of adjacent balls. It is preferred that said spacers are disposed completely within the or their associated race. Preferably, each spacer has a respective complementary surface which engages at least a portion of two adjacent balls.
It is preferred that said spacers are seated on the bearing surfaces of the inner and outer rings. The spacers may abut an inner surface of the outer ring and also said body portion of the inner ring.
In a preferred embodiment of the invention, there are provided two bearing surfaces on the circumferential rib and said edge is therebetween. The edge is preferably circumferential and said body portion may be cylindrical.
In accordance with a second aspect of the present invention there is provided a single track bearing assembly comprising an outer ring providing an outer bearing surface, an inner ring providing an inner bearing surface and a set of balls disposed in a race defined between said inner and outer bearing surfaces wherein said bearing assembly further comprises means associated with the race for separating circumferentially any two adjacent balls and wherein at least part of said separator means occupies a position which is disposed in said race.
It is preferred that said inner ring is formed in one piece.
Preferably, said inner ring is deformable thereby allowing a snap-fit locking arrangement with said balls and the bearing surfaces preferably wrap around the balls thereby restricting movement of the balls in a direction perpendicular to the plane in which they lie.
Preferably, said means spaces apart circumferentially each ball from an adjacent ball. The separator means may be formed as an integral ring like element.
It is preferred that said separator means is provided by individual spacers and each spacer separates a pair of adjacent balls. Preferably, said spacers are disposed completely within the race. Each spacer preferably has a respective complementary engagement surface with a portion of two adjacent ball bearings.
In a preferred embodiment, the spacers are seated on the inner and outer bearing surfaces.
The bearing assembly is preferably made from plastics materials and may be nylon or acetal plastics.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a sectional side view of a known single track ball bearing assembly;
Figure 2 is a sectional side view of a ball bearing assembly according to an embodiment of the present invention;
Figure 3 is a partial side view of the bearing assembly shown in figure 2 taken along line X-X and shown without the balls;
Figure 4 is a plan view of a set of balls and spacers according to a further embodiment of the present invention; and
Figure 5 is a side sectional view of the balls and spacers illustrated in figure 4 taken along line A-A.
Referring now to figures 2 and 3, a ball bearing assembly is indicated generally by the numeral 30. The bearing assembly comprises an outer ring 32, an inner ring 34, a first and second set of balls 36, 38 and spacers 40. The outer ring 32 has a centrally located circumferential rib 42 which extends radially from an inner surface 44 of outer ring 32.
The inner ring 34 comprises, for ease of assembly, a first and second part 46, 48 which together form a cylindrical portion 50 having a cylindrical flange 52 at each end thereof. The flanges effectively form a channel therebetween in which the two sets of balls are disposed. The inner ring 34 is provided with a first and a second inner ring raceway 54, 56 le bearing surfaces, which are concave and located at the junctions between the cylindrical portion 50 and the two end flanges 52. The extent of curvature of the inner ring raceways is such as to match that of the balls.
The outer ring 32 has a first and a second outer ring raceway 64, 66 which are concave and formed by the surfaces of the circumferential rib and inner surface of the outer ring. The extent of curvature of the outer raceways matches that of the balls.
As will be noted from figure 2, the first inner ring raceway 54 lies diagonally opposing said first outer ring raceway 64 and similarly, said second inner ring raceway 56 lies diagonally opposing the second outer ring raceway 56. A pair of inner and outer raceways form a race.
The circumferential rib 42 extends into the aforesaid channel and has an edge 62 which is formed between said first and second outer ring raceway. Edge 62 is spaced from and concentric with cylindrical portion 50. The edge 62 lies in a plane which is axially spaced inbetween the planes in which each set of balls are disposed.
A spacer 40 takes the general shape as that of a segment of a ring and has rounded diagonally opposing corners which match the concave shape of the inner and outer ring raceways. The ends 68 of the spacers are concave and match the curvature of the balls. A spacer is positioned between each pair of adjacent balls such that its ends partly envelope two adjacent ball bearings. The spacer associated with each race are disposed entirely between a bearing surface of the guide ring and an inner surface of the opposing flange. Hence, no part of the spacers is interposed between said edge 62 and the cylindrical portion 50. In position, the spacers abut the inner and outer ring raceways of the race in which they are disposed. The spacers are disposed in a position which extends radially outwardly from said cylindrical portion and beyond said edge 62. The spacers overlap the inner and outer ring raceways.
Due to the fact that the spacers are not interposed between the edge and the cylindrical portion as is the case with a conventional caged type bearing assembly, the width of the ring can be the same as that for a full ball complement type bearing assembly. Consequently, the invention provides a bearing assembly having improved side loading strength over that of a caged type bearing and maintains separation of the balls thereby reducing the friction problems arising from the balls contacting one another as experienced with a full ball complement type bearing.
With reference to figures 1, 4 and 5 a further embodiment of the present invention will now be described. The construction of the ball bearing illustrated in figure 1 is described above but in accordance with this further embodiment each ball 14 is separated from its adjacent balls by spacers 70. The spacers are disposed completely within the race defined between the inner and outer bearing surfaces 26, 20 and are shaped so as to abut the bearing surfaces. As can be seen with reference to figure 4, the ends of each spacer have complementary faces which engage with a portion of an adjacent ball. The spacers ensure that adjacent balls do not contact one another thereby reducing the problems associated with friction and noise.
