Abstract
Abstract A bearing assembly is constructed by winding a resin impregnated low friction thread on an inner bearing member. The thread turns are then compacted together and the resin caused to fuse bonding the turns in a continuous matrix. Around the outside of the thread layer an outer member is then constructed in locked engagement therewith and the thread layer and outer member together form a relatively movable bearing member around the inner bearing member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
111 words
The method of making a bearing comprising: winding on the exterior bearing surface of an inner bearing member through a plurality of juxtaposed helical turns a continuous strand of bondable low friction thread impregnated with a bonding resin, treating said windings to form a low friction bearing layer including compacting the thread turns together and into close conformity with the bearing surface of the inner bearing member and fusing together the resin of adjacent turns to bond the thread turns together in a continuous matrix, and constructing an outer member about the bearing layer in locked engagement therewith to form an outer relatively movable bearing member around the inner bearing member.
Claim 2
Independent Claim
111 words
The method of making a bearing comprising: winding on the exterior bearing surface of an inner bearing member through a plurality of juxtaposed helical turns a continuous strand of bondable low friction thread impregnated with a bonding resin, treating said windings to form a low friction bearing layer including compacting the thread turns together and into close conformity with the bearing surface of the inner bearing member and fusing together the resin of adjacent turns to bond the thread turns together in a continuous matrix, and constructing an outer member about the bearing layer in locked engagement therewith to form an outer relatively movable bearing member around the inner bearing member.
Claim 3
Dependent Claim
25 words
The invention as defined by claim 1 characterized in that said exterior bearing surface of the inner bearing member is a spherically curved convex surface.
Claim 4
Dependent Claim
61 words
The invention defined in claim 1 characterized in that the resin is a thermosetting resin and at the time of treating said windings the resin is in the B-stage and the treating comprises softening of the resin and compacting together of the thread turns to effect a coalescence of the resin and at least partially curing the resin into the C-stage.
Claim 5
Dependent Claim
30 words
The invention defined by claim 3 characterized in that following construction of the outer member about the bearing laYer the resin is treated to fully cure it into the C-stage.
Claim 6
Dependent Claim
29 words
The invention defined by claim 1 characterized in that said construction of the outer member comprises electrodepositing metal onto the bearing layer to build up the outer member thereon.
Claim 7
Dependent Claim
27 words
The invention defined by claim 5 characterized in that prior to said electrodeposition the bearing layer is rendered electrically conductive by applying thereto an electrically conductive coating.
Claim 8
Dependent Claim
43 words
The invention defined by claim 6 characterized in that said treating of the winding comprises impressing on the exposed surface a multiplicity of indentations, and said electrically conductive coating and electrodeposition is applied to said indented surface to effect a mechanical interlock therebetween.
Claim 9
Dependent Claim
24 words
The invention defined by claim 4 characterized in that the construction of the outer member comprises an electrodeposition of metal on the bearing layer.
Claim 10
Dependent Claim
65 words
The invention defined by claim 2 characterized in that during treating of the windings prior to constructing the outer member thereabout the exposed surface is indented to provide a series of recesses, and the outer member is constructed by electrodepositing metal on such indented surface, and following the electrodeposition of the outer member the resin is further treated to fully cure it to the C-stage.
Claim 11
Dependent Claim
25 words
The invention defined by claim 1 characterized in that said outer member and bearing layer are adhesively secured together to effect the interlocked engagement therebetween.
Claim 12
Dependent Claim
24 words
The invention defined by claim 10 characterized in that said outer member is swaged in situ about the bearing layer and adhesively secured thereto.
Claim 13
Independent Claim
103 words
The method of making a bearing having an inner ball member entrapped within an outer housing comprising: winding on the exterior of the inner ball member through a plurality of juxtaposed helical turns a continuous strand of bondable low friction thread impregnated with a bonding resin, treating said turns with heat and pressure to compact the thread turns together and into close conformity with the surface of the inner ball member and to cause coalescing of the resin of adjacent turns and bonding of the thread turns together in a continuous solidified structure, and electrodepositing a metal housing around the low friction layer.
Claim 14
Independent Claim
103 words

Claim 16
Dependent Claim
25 words
The invention defined by claim 11 characterized by coating the low friction layer with a conductive coating prior to the electrodeposition of the metal housing.
Claim 17
Independent Claim
135 words
The method of making a bearing having an inner ball member entrapped within an outer housing comprising: winding on the exterior of the inner ball member through a plurality of juxtaposed helical turns a continuous strand of bondable low friction thread impregnated with a bonding resin, treating said turns with heat and pressure to compact the thread turns together and into close conformity with the surface of the inner ball member and to cause coalescing of the resin of adjacent turns and bonding of the thread turns together in a continuous solidified structure, adhering to the exterior of the low friction layer a pair of identical annuli arranged in confronting relation and having concave internal surfaces mating with the spherical shape of the low friction layer, and locking said annuli within an outer housing member.
