Claims
- 1. A bearing member including axially opposite ends and comprising a layer of self-lubricating material forming a continuous and seamless inner bearing surface defining an axial bore and including a circumferentially spaced plurality of bearing segments extending axially from and between said opposite ends and in circumferentially spaced apart relation to each other, and a like plurality of lubrication grooves located between said bearing segments, extending axially from and between said opposite ends and intermediate said bearing segments, and an outer surface, and an overlayment secured to said outer surface of said layer of self-lubricating material.
- 2. A bearing member in accordance with claim 1 wherein said grooves are generally triangular in cross-section and include a base extending between adjacent ones of said cylindrical segments, and a depth extending radially outwardly from said base.
- 3. A bearing member in accordance with claim 2 wherein said base is substantially equal to said depth.
- 4. A bearing member in accordance with claim 1 wherein said overlayment includes a plurality of filaments wound around said layer of self-lubricating material.
- 5. A bearing member in accordance with claim 1 and further including a hardenable liquid bonding together said layer of self-lubricating material and said overlayment.
- 6. A bearing member in accordance with claim 1 wherein said grooves extend rectilinearly.
- 7. A bearing member in accordance with claim 1 wherein said grooves extend helically for an arcuate distance of less than 360 degrees.
- 8. A bearing member including axially opposite ends and comprising a layer of self-lubricating material forming a continuous and seamless inner bearing surface defining an axial bore and including a circumferentially spaced plurality of bearing surfaces extending axially from and between said opposite ends and in circumferentially spaced apart relation to each other, said layer of self-lubricating material also having a like plurality of lubrication grooves located between said cylindrical segments, opening into said bore, and said layer of self-lubricating material also having an outer surface including a like plurality of circumferentially spaced radially outwardly extending projections extending axially from and between said opposite ends and in generally aligned radially outward relation to said grooves, and an overlayment secured to said outer surface of said layer of self-lubricating material.
- 9. A bearing member in accordance with claim 8 wherein said grooves are generally triangular in cross-section and include a base extending between adjacent ones of said cylindrical segments, and a depth extending radially outwardly from said base.
- 10. A bearing member in accordance with claim 9 wherein said base is substantially equal to said depth.
- 11. A bearing member in accordance with claim 8 wherein said overlayment includes a plurality of filaments wound around said layer of self-lubricating material.
- 12. A bearing member in accordance with claim 8 and further including a hardenable liquid bonding together said layer of self-lubricating material and said overlayment.
- 13. A bearing member in accordance with claim 8 wherein said grooves extend rectilinearly.
- 14. A bearing member in accordance with claim 8 wherein said grooves extend helically for an arcuate distance of less than 360 degrees.
