Abstract
Abstract A pair of relatively rotatable support members, separated by a gap centered on the axis of rotation, engage each other through a multiplicity of elastically deformable sliding heads of low-friction plastic material projecting from one support member into the gap and resting against a confronting contact surface of the other support member. Each sliding head is tightly embraced by a rigid retaining sleeve which is positively guided on the first support member for movement perpendicular to the contact surface and is urged by one or more biasing springs toward that surface so as to surround the entire projecting portion of the sliding head under all loading conditions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
A bearing comprising: a first and a second support member mounted for relative rotation about an axis and separated by a gap centered on said axis; a multiplicity of sliding heads carried on said first support member and extending across said gap to a confronting surface of said second support member in low-friction contact therewith, said sliding heads consisting essentially of elastically deformable material at least in the vicinity of said confronting surface; a multiplicity of rigid retaining sleeves respectively embracing said sliding heads, said sleeves being positively guided on said first support member for displacement perpendicular to said confronting surface; and spring means on said first support member urging said sleeves into engagement with said confronting surface.
Claim 2
Dependent Claim
118 words
A bearing comprising: a first and a second support member mounted for relative rotation about an axis and separated by a gap centered on said axis; a multiplicity of sliding heads carried on said first support member and extending across said gap to a confronting surface of said second support member in low-friction contact therewith, said sliding heads consisting essentially of elastically deformable material at least in the vicinity of said confronting surface; a multiplicity of rigid retaining sleeves respectively embracing said sliding heads, said sleeves being positively guided on said first support member for displacement perpendicular to said confronting surface; and spring means on said first support member urging said sleeves into engagement with said confronting surface.
Claim 3
Dependent Claim
27 words
A bearing as defined in claim 1, further comprising a multiplicity of collars surrounding said sliding heads, said collars being fixedly secured to said first support member.
Claim 4
Dependent Claim
19 words
A bearing as defined in claim 2 wherein said sleeves are inserted between said collars and said sliding heads.
Claim 5
Dependent Claim
33 words
A bearing as defined in claim 2 wherein said sliding heads have reduced necks remote from said confronting surface, said collars surrounding said reduced necks and being in turn surrounded by said sleeves.
Claim 6
Dependent Claim
35 words
A bearing as defined in claim 4 wherein said sliding heads have beveled peripheral shoulders converging toward said necks, said collars having complementarily beveled annular faces adjoining said shoulders and diverging toward said confronting surface.
Claim 7
Dependent Claim
30 words
A bearing as defined in claim 1 wherein said first support member is provided with a multiplicity of recesses receiving at least said spring means and portions of said sleeves.
Claim 8
Dependent Claim
29 words
A bearing as defined in claim 1 wherein said sleeves have portions offset from said spring means for abutting against said first support member under a maximum loading force.
Claim 9
Dependent Claim
32 words
A bearing as defined in claim 1 wherein said first support member is provided with a multiplicity of dished holders fixedly secured thereto, said sliding heads being projectingly received in said holders.
Claim 10
Dependent Claim
19 words
A bearing as defined in claim 8 wherein said spring means and portions of said sleeves surround said holders.
Claim 11
Dependent Claim
31 words
A bearing as defined in claim 9 wherein said sliding heads have reduced rims projecting laterally beyond said holders, said portions of said sleeves having inner projections overlain by said rims.
