Abstract
Abstract A thrust plate utilized between the end face of a bearing pin of a trunnion in a universal joint and the bottom wall of a bushing on the bearing pin is formed of a wear-resistant heat-stable plastic material and lubricant grooves are formed in at least one surface of the plate. A plurality of protuberances which may be in the form of honeycombs, cams, or cam-ridges are formed in a surface of the plate between the lubricant grooves and occupy an area such that the deformation resistance under compression load will be less than two-thirds of the corresponding resistance value for the plate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A thrust plate for between an end face of a bearing pin of a trunnion in a universal joint and a bottom wall of a bushing on the bearing pin and comprising a wear-resistant heat-stable plastic material, there being lubricant grooves in a surface of said plate, and raised portions comprising a plurality of protuberances on said surface of said plate between said grooves, said raised portions being plastically deformable during assembly of the bushing on the bearing pin so that the desired end play is obtained between the bushing bottom wall and bearing pin end surface, said raised portions occupying an area such that deformation resistance under compression load will be less than a predetermined resistance value for said plate.
Claim 2
Dependent Claim
121 words
A thrust plate for between an end face of a bearing pin of a trunnion in a universal joint and a bottom wall of a bushing on the bearing pin and comprising a wear-resistant heat-stable plastic material, there being lubricant grooves in a surface of said plate, and raised portions comprising a plurality of protuberances on said surface of said plate between said grooves, said raised portions being plastically deformable during assembly of the bushing on the bearing pin so that the desired end play is obtained between the bushing bottom wall and bearing pin end surface, said raised portions occupying an area such that deformation resistance under compression load will be less than a predetermined resistance value for said plate.
Claim 3
Dependent Claim
29 words
A thrust plate as claimed in claim 1 wherein the deformation resistance of said raised surface portions will be less than two-thirds of the resistance value for the plate.
Claim 4
Dependent Claim
18 words
A thrust plate as claimed in claim 4 wherein said protuberances comprise one of honeycombs, cams and cam-ridges.
Claim 5
Dependent Claim
14 words
A thrust plate as claimed in claim 1 wherein said plate comprises a disc.
Claim 6
Dependent Claim
20 words
A thrust plate as claimed in claim 1 wherein said raised surface portions are on both sides of said plate.
Claim 7
Dependent Claim
31 words
A thrust plate as claimed in claim 1 wherein said lubricant grooves are in both sides of said plate and said raised surface portions are on both sides of said plate.
