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 a number of load carrying balls and idler balls between the shaft and the bearing assembly, idler balls interposed between said load carrying balls, said idler balls having a diameter somewhat less than said load carrying balls.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 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 a central opening for the passage of a shaft therethrough, the inner sleeve having a number of tracks defining paths for the circulation of balls, circulation of a number of load carrying balls and idler balls between said sleeves and said shaft during relative movement between said shaft and said bearing assembly, said idler balls interposed between said load carrying balls, said idler balls having a diameter somewhat less than said load carrying balls, the outer surface of the inner sleeve being polyhedronal in shape, the inner surface of the outer sleeve being provided with a number of guideways, the intersections of the plane portions defining the outer surface of the inner sleeve registering with said guideways, said inner surface of the outer sleeve is further provided with a number of substantially concave bearing surfaces aligned with said tracks such that they provide a rolling bearing surface for said load carrying balls while said load carrying balls are in their loaded state.
Claim 2
Dependent Claim
185 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 a central opening for the passage of a shaft therethrough, the inner sleeve having a number of tracks defining paths for the circulation of balls, circulation of a number of load carrying balls and idler balls between said sleeves and said shaft during relative movement between said shaft and said bearing assembly, said idler balls interposed between said load carrying balls, said idler balls having a diameter somewhat less than said load carrying balls, the outer surface of the inner sleeve being polyhedronal in shape, the inner surface of the outer sleeve being provided with a number of guideways, the intersections of the plane portions defining the outer surface of the inner sleeve registering with said guideways, said inner surface of the outer sleeve is further provided with a number of substantially concave bearing surfaces aligned with said tracks such that they provide a rolling bearing surface for said load carrying balls while said load carrying balls are in their loaded state.
Claim 3
Dependent Claim
22 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein said load carrying balls and said idler balls are metallic balls.
Claim 4
Dependent Claim
25 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein said load carrying balls are metallic balls and said idler balls are non-metallic balls.
Claim 5
Dependent Claim
20 words
An anti-friction ball bearing assembly in accordance with claim 3 wherein said idler balls are manufactured from a self-lubricating plastic.
Claim 6
Dependent Claim
27 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein said load carrying balls and said idler balls are carried in said tracks by retaining means.
Claim 7
Dependent Claim
38 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein said idler balls are plastic balls and are in a preloaded state between said load carrying balls thereby exerting a preloaded force on said load carrying balls.
Claim 8
Dependent Claim
23 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein there is one idler ball interposed between two adjacent load carrying balls.
