Abstract
Abstract An anti-friction ball bearing assembly adapted for mounting on a shaft comprising an outer sleeve and an inner sleeve concentrically fitting within the outer sleeve, the inner sleeve having a number of tracks defining paths for the circulation of balls between the sleeves and the shaft during movement between the shaft and the bearing assembly, the outer surface of the inner sleeve being polyhedronal in shape, the inner surface of the outer sleeve being substantially polyhedronal in shape and generally conforming to the shape of the outer surface of the inner sleeve, the inner surface of the outer sleeve having a number of axially extending arcuately shaped bearing raceways whose radii generally correspond to the radii of the balls, the balls being in full race curvature contact with the raceways while the balls are in their active load carrying positions between the shaft and the outer sleeve.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
An anti-friction ball bearing assembly comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having an opening therethrough to slidably accommodate a shaft, said inner sleeve having a number of tracks defining paths for the circulation of balls between said sleeves and said shaft during movement between said shaft and said bearing assembly, the outer surface of the inner sleeve being polyhedronal in shape, the inner surface of the outer sleeve being substantially polyhedronal in shape and generally conforming to the shape of said outer surface of said inner sleeve, the inner surface of said outer sleeve having a number of axially extending arcuately shaped bearing raceways whose radii generally correspond to the radii of the balls, the balls being in full race curvature contact with said raceways while said balls are in their active load carrying positions between said shaft and said outer sleeve.
Claim 2
Dependent Claim
153 words
An anti-friction ball bearing assembly comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having an opening therethrough to slidably accommodate a shaft, said inner sleeve having a number of tracks defining paths for the circulation of balls between said sleeves and said shaft during movement between said shaft and said bearing assembly, the outer surface of the inner sleeve being polyhedronal in shape, the inner surface of the outer sleeve being substantially polyhedronal in shape and generally conforming to the shape of said outer surface of said inner sleeve, the inner surface of said outer sleeve having a number of axially extending arcuately shaped bearing raceways whose radii generally correspond to the radii of the balls, the balls being in full race curvature contact with said raceways while said balls are in their active load carrying positions between said shaft and said outer sleeve.
Claim 3
Dependent Claim
26 words
An anti-friction ball bearing assembly according to claim 1 wherein said outer surface of said inner sleeve comprises a number of continuous axially extending planar surfaces.
Claim 4
Dependent Claim
26 words
An anti-friction ball bearing assembly according to claim 1 wherein said inner surface of said outer sleeve comprises a number of continuous axially extended planar surfaces.
Claim 5
Dependent Claim
40 words
An anti-friction ball bearing assembly according to claim 3 wherein said axially extended arcuate bearing raceways are positioned on said inner surface of said outer sleeve intermediate the lines described by the inner section of said axially extending planar surfaces.
Claim 6
Dependent Claim
35 words
An anti-friction ball bearing assembly according to claim 1 wherein the inner surface of the inner sleeve is substantially cylindrical in form and adapted to register with and be mounted on a subsTantially circular shaft.
