Abstract
Abstract A self-lubricating journal bearing includes an arcuate bearing plate having a concave bearing surface. A plurality of lubricant plugs are positioned in apertures in the surface of said plate and are adapted to engage a rotating journal supported on said bearing surface for providing lubrication between said journal and said bearing plate. The lubricant plugs comprise an oil and polymer lubricating composition. The apertures and plugs are arranged to provide continuous lubrication over substantially the entire bearing surface as the journal rotates thereon, and coolant grooves are cut into the bearing surface of said bearing plate in a generally X-shaped pattern for channeling liquid coolant between the journal and the bearing plate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
101 words
In a journal bearing subjectable to severe conditions, an arcuate bearing plate having a concave bearing surface, a plurality of apertures opening into said surface, a plug of lubricant containing material comprising an oil and a polymer composition inserted into each of said apertures and adapted to engage a rotating journal supported on said bearing surface for providing lubrication between said journal and said bearing plate, and coolant grooves cut into and extending substantially entirely across the bearing surface of said bearing plate for channeling a liquid coolant other than said lubricant containing material between the journal and the bearing plate.
Claim 2
Dependent Claim
101 words
In a journal bearing subjectable to severe conditions, an arcuate bearing plate having a concave bearing surface, a plurality of apertures opening into said surface, a plug of lubricant containing material comprising an oil and a polymer composition inserted into each of said apertures and adapted to engage a rotating journal supported on said bearing surface for providing lubrication between said journal and said bearing plate, and coolant grooves cut into and extending substantially entirely across the bearing surface of said bearing plate for channeling a liquid coolant other than said lubricant containing material between the journal and the bearing plate.
Claim 3
Dependent Claim
17 words
A journal bearing as defined in claim 1 wherein said coolant grooves are generally X-shaped in pattern.
Claim 4
Dependent Claim
160 words
In a self-lubricating journal bearing subjectable to severe conditions, an arcuate bearing plate having a concave bearing surface, a plurality of apertures opening into said surface, a frusto-conical lubricant plug inserted into each of said apertures and adapted to engage a rotating journal supported on said bearing surface for providing lubrication between said journal and said bearing plate, each said lubricant plug comprising an oil and polymer lubricating composition, each said plug having an air escape channel defined in a wall thereof, said apertures and plugs being arranged to provide continuous lubrication over substantially the entire bearing surface as the journal rotates thereon, and coolant grooves cut into and extending substantially entirely across the bearing surface of said bearing plate in a generally X-shaped pattern for channeling a liquid coolant other than said oil and polymer lubrication composition between the journal and the bearing plate whereby said lubricated bearing plate is capable of supporting heavy journals under high temperature conditions.
