Description
This invention relates generally to an antifriction bearing assembly and more particularly to an antifriction bearing assembly having a desired end play or preload It is already known from the U.S. Patent 3,794,393 granted to Charles B. Hurd et al on February 26, 1974 for a "Roller Bearing Assembly" to provide a double row roller bearing assembly having a two piece outer race in which the end play or preload is controlled by a split snap ring of -selected width to maintain a separable outer bearing race at a desired location in the bore of the second race piece.
While the Hurd et al Roller Bearing Assembly may be suitable for some applications, it has some drawbacks in that the split snap ring used to locate the race 62 ma~es automated assembly o, the bearing assembly difficult in general and even more so since split snap rings vary in width and thus in spring rate from bearing assembly to bearing assembly. Another draw-back is that the split ring retention device utilized in the Hurd et al Bearing Assembly does not lend itself to bearing assemblies in which the end play or preload is adjusted by an ,.. , . . , - . , ,, . . . . , . ~ . .

inner race of two piece construction.
Broadly it is the object of this invention to pro-vide an antifriction bearing assembly having an improved means for providing a desired end play or preload.
Another object of this invention is to provide an antifriction bearing assembly utilizing means to provide a desired end play or preload which lends itself to automated assembly.
Another object of this invention is to provide an antifriction bearing assembly having a preadjusted end play or preload comprising a two piece race wherein one race piece is accurately positioned on another race piece by a keeper -means which engages the first race piece for a full 360.
Still another object of this invention is to pro-viae an antifriction bearing assembly having a preadjusted end play or preload in which the means positioning the one race part with respect to another race part includes hardened ;~
and ground members enaaging the one race part for increased durability and positioning accuracy.
Yet another object of this invention is to provide an antifriction bearing assembly having means for providing a preadjusted end play or preload which is suitable for an anti-friction bearing assembly which utilizes an inner race of two piece construction to achieve a desired end play or preload.
Other objects and features of the invention will become apparent to those skilled in the art as the disclosure is made in the following detailed description of a preferred embodiment of the invention as illustrated in the accompany-ing sheet of drawing in which:
Figure 1 is a longitudinal section through a wheel bearing assembly embodying this invention, Figure 2 is a section taken along the line 2-2 of ~08636~ ;
Figure 1, and ~igure 3 is an enlargement of-a portion of Figure 1.
Referring now to Figure 1 and by way of background there is illustrated a rear wheel bearing assembly 10 used ~ ;~
for instance in an independently suspended rear wheel of a front wheel drive automobile. To this end the rear wheel bearing assembly 10 incorporates a dead or non-rotatable spindle 12'comprising an axle 14 and integral circular mount- -ing flange 16. The mounting flange 16 carries a plurality of bolts 18 for securing the assembly 10 to suitable struc-ture in the automobile.
The axle 14 as it progresses from the flange 16 toward the free end of the axle 14 includes a cylindrical seal land 20, an angular contact raceway 22, a conical sec-tion 24, and a cylindrical portion 26 of reduced diameter.
The cylindrical portion 26 has a square shaped inboard groove 28 and a trapezoidal shaped outboard groove 30 ;
adjacent the free end of the axle 14.
The bearing assembly 10 further includes a hub 32 20 , comprising an outer race 34 and integral wheel mounting flange 36. The wheel mounting flange 36 is rectangularly shaped to provide access to the bolt holes in the circular mounting flange 16. (The section of the wheel mounting flange 36 shown in Figure 1 is along the diagonal of the rectangle through the bolt holes located at the corners of the rectangle.) The outer race 34 has a pair of axially spaced angular contact raceways 38 and 40 separated by a com~on shoulder defining a reduced diameter bore 42 in the medial portion of the bearing.
A first complement of bearing balls 44 circumfer-entially spaced by a separator rides on the inner and outer ,~ .
raceways 22 and 38. ~ second complement of bearing balls 46 rides on the outer raceway 40 and the angular contact race-way 48 of a separable inner race 50 which is fitted on the cylindrical portion 26 of the axle 14.
The inner race 50 is positioned on the cylindrical portion 26 to produce a desired end play or preload in the bearing assembly by selected width keeper ring parts 54 dis- -posed in the groove 28 end to end as shown in Figure 2. When the bearing is preloaded the bearing balls 44 and 46 have pressure angles such that opposing thrust loads acting toward the medial plane 52 of the bearing are imposed on the outer race 34 via the raceways 38 and 40. Each of the keeper ring parts 54 are shaped so that the keeper ring parts 54 are mountable in the groove 28 without requiring elastic deforma-~31 tion and together engage the outboard face of the inner race ; 50 for a full 360. In the inner bearing arrangement shown .
in the drawing, the keeper ring parts 54 are semicircular ~~
as shown in ~igure 2 which minimizes the number of keeper ring parts. The keeper ring parts 54 are hardened to a Rockwell Hardness between 55 and 60 on the C scale for dura-bility, ground for extreme dimensional accuracy in width and segregated in .0002 inch width classes for producing a desired end play or preload. The groove 28 prefera~ly under- ;~
cuts the raceway by a small amount.
The keeper ring parts 54 are bottomed and main-tained in the square shaped groove 28 by a sheet metal retainer ring 56 which has a conical inner surface 58 engag- -ing a mating frustoconical outer surface 60 of each of the keeper ring parts 54. The retainer ring 56 has a cylindrical end portion 62 which is swaged or rolled at 64 into the ; trapezoidal shaped groove 30 to securely fasten the retainer ring 56 to the axle 14.
The retainer ring 56 may also include a flange 66 having an outer diameter greater than the diameter of the bore 42 to prevent disassembly of the bearing in the event of catastrophic failure of the internal bearing components.
The assembly 10 may also include bearing seal 69 carried at the end of the hub 32 ad~acent the circular mount-ing flange 16 which has a flexible sealing lip riding on the cylindrical land 20 of the axle 14. ~ grease cap 71 mounted in the bore at the other end of the hub 34 seals the other 10 end of the bearing assembly 10. ~ `~
The axial end play or preload of the bearing assem-bly 10 is obtained by the axial positioning of the separable inner race 50 on the axle 14. To maintain the axial end play or preload the inner race 50 is pressed on the cylindri- -~
cal portion 26 of the axle 14 to the proper location to give ~ , the desired end play or preload and positively retained in position. ~ ;
When assembling the bearing 10 the complements of bearing balls 44 and 46 and hùb 34 are sub-assembled with the spindle 12. The separable inner race 50 is then pressed on the cylindrical portion 26 of the axle 14 to a convenient location and the axial end play and distance from the inner -;
race back face 68 and the radial face 70 of the square shaped ~ -groove 28 away from the inner race are measured. Using the measured values and the desired ~final end play of the assembly the required width of keeper ring parts 54 to be inserted in the groove 28 is determined. The separable inner race 50 may then be repositioned axially to its final desired location and keeper ring parts 5~ of proper selected width inserted in the groove 28, or the keeper ring parts may be forced into the groove 28 between the separable bearing race back face 68 and the groove end face 70 to obtain the final .,,i,~ , 10863~;4 positioning for the desired end play or preload. Once the keeper ring parts 54 are bottomed in the groove 28, the - retaining ring 56 is placed on the axle spindle with its tapered inner surface 58 in contact with the ~apered outer surfaces 60 of the keeper ring parts 54. The cylindrical portion 62 of the retaining ring is then swaged or rolled into the trapezoidal shaped groove 30 to permanently lock the retaining ring 56 in place and contain the keeper ring parts 54 in the groove 28.
Any thrust force applied to the bearing assembly tending to move the separable inner race 50 toward the right as viewed in Figures 1 and 3 and thus changing the preset end play or preload is transmitted from the inner race 30 through the end face 68 to the keeper ring parts 5~ and then into the axle 14 through the groove end face 70. The keeper ring parts 54 and spindle 12 are of a suitable hardness to ~:
resist permanent defor~ation thus preventing m~vement of the separable inner race 50 and change of the preset end play or -preload.
. We wish it to be understood that we do not aesire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
While the Hurd et al Roller Bearing Assembly may be suitable for some applications, it has some drawbacks in that the split snap ring used to locate the race 62 ma~es automated assembly o, the bearing assembly difficult in general and even more so since split snap rings vary in width and thus in spring rate from bearing assembly to bearing assembly.
