Abstract
Abstract An anti-friction linear ball bearing assembly adapted for mounting on a shaft to provide omnidirectional load capability between the shaft and a support member, comprising an outer sleeve and an inner sleeve concentrically fitting within the outer sleeve, the inner sleeve having a helical track defining a helical path for the circulation of a number of load carrying balls between said shaft and the bearing assembly, means attaching the ball bearing assembly to the support member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
An anti-friction ball beAring assembly adapted for mounting on a shaft to provide anti-friction linear bearing support between said shaft and a support member, comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, the inner sleeve having a helical track defining a helical path for the circulation of a number of load carrying balls between said shaft and said bearing assembly, means attaching said ball bearing assembly to a support member for rotatable movement therebetween.
Claim 2
Dependent Claim
80 words
An anti-friction ball beAring assembly adapted for mounting on a shaft to provide anti-friction linear bearing support between said shaft and a support member, comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, the inner sleeve having a helical track defining a helical path for the circulation of a number of load carrying balls between said shaft and said bearing assembly, means attaching said ball bearing assembly to a support member for rotatable movement therebetween.
Claim 3
Dependent Claim
70 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein said means for attaching said ball bearing assembly to said support member for rotatable movement therebetween comprises at least one bearing means attached to the outer surface of said outer sleeve, a third sleeve concentrically fitting around said outer sleeve and in rotatable bearing contact with said bearing means, said third sleeve being fixedly attached to said support member.
Claim 4
Dependent Claim
18 words
An anti-friction ball bearing assembly in accordance with claim 2 wherein said bearing means comprises two ball bearings.
Claim 5
Dependent Claim
34 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein said inner sleeve is held in concentric alignment with said outer sleeve, both radially and axially, by first and second holding means respectively.
Claim 6
Dependent Claim
44 words
An anti-friction ball bearing assembly in accordance with claim 4 wherein said second holding means comprises at least two annular rings, each disposed in grooves at the ends of the inner surface of the outer sleeve and the outer surface of said inner sleeve.
Claim 7
Dependent Claim
42 words
An anti-friction ball bearing assembly in accordance with claim 4 wherein said first holding means comprises at least one spline member integral with said inner sleeve and in interlocking engagement with a corresponding groove on the inner surface of said outer sleeve.
Claim 8
Dependent Claim
45 words
An anti-friction ball bearing assembly in accordance with claim 2 wherein the outer surface of the third sleeve is a smooth surface of revolution, two annular grooves disposed at each end of said third sleeve for fixedly attaching said bearing assembly to said support member.
Claim 9
Dependent Claim
32 words
An anti-friction ball bearing assembly in accordance with claim 1 wherein the inner surface of the outer sleeve is cylindrical in shape and provides a raceway surface for said load carrying balls.
Claim 10
Dependent Claim
20 words
An anti-friction ball bearing assembly in accordance with claim 8 wherein said raceway surface is coated with a self-lubricating plastic.
Claim 11
Dependent Claim
16 words
An anti-friction ball bearing assembly in accordance with claim 9 wherein said self-lubricating plastic is polytetra-fluoroethylene.
