Abstract
Abstract A bearing utilizing a plurality of wires has the races for the roller bodies provides individual lining strips between each wire and the groove walls of the receiving structural members of the bearing. These lining strips are braced in two mutually perpendicular directions against two mutually perpendicular countersurfaces of the grooves and a yieldable connection can be provided between the pair of lining strips in one or both of the grooves so that the bearing prestress and play can be adjusted.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
A rolling bearing, comprising: a pair of juxtaposed relatively displaceable bearing members relatively shiftable in a guide direction, separated by a bearing gap extending in said direction, and formed with respective mutually registering bearing grooves; a pair of race wires received in each of said grooves; an array of rolling bodies uniformly spaced in said direction rolling upon riding surfaces of said race wires; and a respective lining strip individual to each of said wires interposed between the respective wire and the respective member, each of said lining strips: having an inner side turned toward the respective race wire and form-identical to the respective race wire and shaped to form a bed in surface contact with the respective race wire all along the length thereof, having an outer side forming respective contact surfaces lying in form-fitting engagement with countersurfaces on walls of the respective groove bracing the respective lining strip in two mutually perpendicular directions both of which are perpendicular to said guide direction and which are respectively transverse to and along said bearing gap, and each of said lining strips in at least one of said grooves being spaced from the other lining strip in said one of said grooves with a selectively variable spacing therebetween.
Claim 2
Dependent Claim
207 words
A rolling bearing, comprising: a pair of juxtaposed relatively displaceable bearing members relatively shiftable in a guide direction, separated by a bearing gap extending in said direction, and formed with respective mutually registering bearing grooves; a pair of race wires received in each of said grooves; an array of rolling bodies uniformly spaced in said direction rolling upon riding surfaces of said race wires; and a respective lining strip individual to each of said wires interposed between the respective wire and the respective member, each of said lining strips: having an inner side turned toward the respective race wire and form-identical to the respective race wire and shaped to form a bed in surface contact with the respective race wire all along the length thereof, having an outer side forming respective contact surfaces lying in form-fitting engagement with countersurfaces on walls of the respective groove bracing the respective lining strip in two mutually perpendicular directions both of which are perpendicular to said guide direction and which are respectively transverse to and along said bearing gap, and each of said lining strips in at least one of said grooves being spaced from the other lining strip in said one of said grooves with a selectively variable spacing therebetween.
Claim 3
Dependent Claim
23 words
The rolling bearing defined in claim 1, further comprising means for yieldably connecting the lining strips spaced with a selectively variable spacing therebetween.
Claim 4
Dependent Claim
56 words
The rolling bearing defined in claim 2 wherein said means for yieldably connecting the lining strips spaced with a selectively variable spacing therebetween includes a hook connection between the two lining strips in said one of said grooves permitting relative displacement of said two lining strips toward one another but limiting their separation from one another.
Claim 5
Dependent Claim
39 words
The rolling bearing defined in claim 2 wherein said means for yieldably connecting the lining strips spaced with a selectively variable spacing therebetween includes a web defining a fold and constituted in one piece with said two lining strips.
Claim 6
Dependent Claim
34 words
The rolling bearing defined in claim 4 wherein said fold has an inwardly concave side, said rolling bearing further comprising a cage spacing said rolling bodies from one another and extending into said fold.
Claim 7
Dependent Claim
14 words
The rolling bearing defined in claim 4 wherein said fold is formed with openings.
Claim 8
Dependent Claim
29 words
The rolling bearing defined in claim 4 wherein said means for yieldably connecting the lining strips spaced with a selectively variable spacing therebetween includes a web formed with openings.
