Abstract
Abstract An anti-friction ball bearing assembly, adapted for mounting within a housing comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having a central opening for the passage of a shaft therethrough, 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, said balls, during a portion of their circulation path, contacting said shaft and the inner surface of said outer sleeve at a plurality of raceway surfaces provided thereon, said outer sleeve having a longitudinal fracture line such that said outer sleeve acts as a biasing means on said balls to effect a preloaded force between said shaft and said balls and said outer sleeve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
An anti-friction ball bearing assembly, adapted for mounting within a housing comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having a central opening for the passage of a shaft therethrough, 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, said balls, during a portion of their circulation path, contacting said shaft and the inner surface of said outer sleeve at a plurality of raceway surfaces provided thereon, said outer sleeve having a longitudinal fracture line such that said outer sleeve acts as a biasing means on said balls to effect a preloaded force between said shaft and said balls and said outer sleeve.
Claim 2
Dependent Claim
133 words
An anti-friction ball bearing assembly, adapted for mounting within a housing comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having a central opening for the passage of a shaft therethrough, 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, said balls, during a portion of their circulation path, contacting said shaft and the inner surface of said outer sleeve at a plurality of raceway surfaces provided thereon, said outer sleeve having a longitudinal fracture line such that said outer sleeve acts as a biasing means on said balls to effect a preloaded force between said shaft and said balls and said outer sleeve.
Claim 3
Dependent Claim
133 words
An anti-friction ball bearing assembly, adapted for mounting within a housing comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having a central opening for the passage of a shaft therethrough, 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, said balls, during a portion of their circulation path, contacting said shaft and the inner surface of said outer sleeve at a plurality of raceway surfaces provided thereon, said outer sleeve having a longitudinal fracture line such that said outer sleeve acts as a biasing means on said balls to effect a preloaded force between said shaft and said balls and said outer sleeve.
Claim 4
Dependent Claim
133 words
An anti-friction ball bearing assembly, adapted for mounting within a housing comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having a central opening for the passage of a shaft therethrough, 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, said balls, during a portion of their circulation path, contacting said shaft and the inner surface of said outer sleeve at a plurality of raceway surfaces provided thereon, said outer sleeve having a longitudinal fracture line such that said outer sleeve acts as a biasing means on said balls to effect a preloaded force between said shaft and said balls and said outer sleeve.
Claim 5
Dependent Claim
30 words
Anti-friction ball bearing assembly in accordance with claim 1 wherein said preloaded force is generated by interference fit between said shaft, said balls and inner surface of said outer sleeve.
Claim 6
Dependent Claim
20 words
Anti-friction ball bearing assembly in accordance with claim 2 wherein said shaft is slightly oversized to cause an interference fit.
Claim 7
Dependent Claim
20 words
Anti-friction ball bearing assembly in accordance with claim 2 wherein said balls are slightly oversized to cause an interference fit.
Claim 8
Dependent Claim
21 words
Anti-friction ball bearing assembly in accordance with claim 2 wherein said inner surface of said outer sleeve is sized slightly undersize.
Claim 9
Dependent Claim
16 words
Anti-friction ball bearing assembly in accordance with claim 1 wherein there is a single fracture line.
Claim 10
Dependent Claim
17 words
Anti-friction ball bearing assembly in accordance with claim 1 wherein there are a plurality of fracture lines.
