Abstract
Abstract Ball bearing assembly with an inner ball race having an outwardly facing groove and bearing balls orbitally disposed around said inner race in said groove, the outer race being formed by the co-action of a shell and a retainer, the shell having a peripheral tire band and a radially inwardly extending sidewall with radially and axially extending steps, the balls being held in part against an innermost step, the bearing ball retainer comprising a cupped annulus butted against another of said steps and held in position by mechanical anchors, such as welds between the retainer annulus and the shell.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
A bearing assembly comprising an inner ball race having an outwardly facing groove, bearing balls orbitally disposed around said inner race in said groove, a metal outer shell having a peripheral tire band and a radially inwardly extending sidewall with a plurality of radially extending flat steps, a bearing ball retainer comprising a cupped metal annulus, said bearing balls bearing laterally against one of said radial steps on the sidewall of the outer shell, said retainer annulus having an outer edge butted against another of the radial steps of the said sidewall, a plurality of metal welds circumferentially spaced about said retainer annulus and between the outer shell and retainer annulus for fastening the retainer annulus in place, said retainer annulus and said one radial step on the sidewall of the outer shell together forming an outer race for said bearing balls.
Claim 2
Dependent Claim
142 words
A bearing assembly comprising an inner ball race having an outwardly facing groove, bearing balls orbitally disposed around said inner race in said groove, a metal outer shell having a peripheral tire band and a radially inwardly extending sidewall with a plurality of radially extending flat steps, a bearing ball retainer comprising a cupped metal annulus, said bearing balls bearing laterally against one of said radial steps on the sidewall of the outer shell, said retainer annulus having an outer edge butted against another of the radial steps of the said sidewall, a plurality of metal welds circumferentially spaced about said retainer annulus and between the outer shell and retainer annulus for fastening the retainer annulus in place, said retainer annulus and said one radial step on the sidewall of the outer shell together forming an outer race for said bearing balls.
Claim 3
Dependent Claim
19 words
The invention of claim 1 in which said retainer annulus has an inner edge facing the inner ball race.
Claim 4
Dependent Claim
37 words
The invention of claim 2 in which said shell has an axially extending shoulder intersecting said radial step, said retainer annulus having a cylindrical margin terminating in said outer edge, said margin being seated into said intersection.
Claim 5
Dependent Claim
40 words
The invention of claim 3 in which the cylindrical margin of said retainer annulus terminates on a plane through the center of said bearing balls, said retainer annulus having an arcuate portion from said plane to its said inner edge.
Claim 6
Dependent Claim
48 words
The invention of claim 1 in which said sidewall comprises an axially extending shoulder intersecting the radial step to which the retainer annulus is butted, said axially extending shoulder having a diameter slightly less than the external diameter of the retainer annulus to require a press fit therebetween.
Claim 7
Dependent Claim
14 words
The invention of claim 1 in which the retainer annulus comprises case hardened metal.
Claim 8
Dependent Claim
13 words
The invention of claim 1 in which the outer shell comprises powdered metal.
Claim 9
Dependent Claim
44 words
The invention of claim 1 in which said sidewall comprises an axially extending shoulder intersecting the radial step to which the retainer annulus is butted, said axially extending shoulder forming a guide for said retainer and supporting it in bearing relation to the balls.
Claim 10
Dependent Claim
20 words
The invention of claim 9 in which the retainer annulus has a cylindrical margin in press fit with said shoulder.
