Claims
- 1. A non-metallic conveyor component comprising:
a race having a bearing surface for relative movement, wherein said bearing surface comprises at least one matrix material and at least one additive, and said race further including a groove on said bearing surface.
- 2. A conveyor component as set forth in claim 1 wherein said groove is helical.
- 3. A conveyor component as set forth in claim 1 wherein said matrix material is selected from the group including phenolic, epoxy, polyurethane, polyetherketone, ultrahigh molecular weight polyethylene, polyimide, polyphthalamide, polyphenylene sulfide, polyesters and fluoropolymers.
- 4. A conveyor component as set forth in claim 3 wherein the additive is selected from the group including molybdenum disulfide, RoyalSen pelletized master batch compositions, the super-hard carbides, nitrides and oxides of titanium, boron, tungsten, tantalum, chromium, molybdenum, glass fibers, boron nitride, and polyaramid fibers.
- 5. A non-metallic conveyor component comprising:
an inner race having an outer bearing surface; an outer race having an inner bearing surface; said outer bearing surface of said inner race and said inner bearing surface of said outer race having relative movement therebetween; and at least one of the outer bearing surface on said inner race and the inner bearing surface of said outer race having a groove thereon.
- 6. A conveyor component as set forth in claim 5 wherein said groove is helical.
- 7. A conveyor component as set forth in claim 5 wherein at least one of said inner and outer bearing surfaces comprise at least one matrix material and one additive.
- 8. A conveyor component as set forth in claim 7 wherein said matrix material is selected from the group including phenolic, epoxy, polyurethane, polyetherketone, ultrahigh molecular weight polyethylene, polyimide, polyphthalamide, polyhenylene sulfide, polyesthers and fluoropolymers.
- 9. A conveyor component as set forth in claim 7 wherein said additive is selected from the group including molybdenum disulfide, RoyalSen pelletized master batch compositions, the super-hard carbides, nitrides and oxides of titanium, boron, tungsten, tantalum, chromium, molybdenum, glass fibers, boron nitride, and a polyaramid fibers.
- 10. A conveyor component as set forth in claim 5 wherein said inner race comprises two components adapted to be connected.
- 11. A conveyor component as set forth in claim 10 wherein said inner race includes a tubular sleeve having a flange and an annular ring.
- 12. A conveyor component as set forth in claim 11 wherein said outer race is carried on said inner race between said annular flange and said annular ring.
- 13. A conveyor component as set forth in claim 5 wherein said inner race has an axial length longer than the axial length of said outer race.
- 14. A conveyor component as set forth in claim 13 wherein the inner race includes an annular end groove on each end thereof.
- 15. A conveyor component as set forth in claim 14 further including a seal disposed in each of said annular end grooves of said inner race to provide a seal.
- 16. A conveyor component as set forth in claim 5 wherein said groove is disposed in said outer bearing surface of said inner race.
- 17. A conveyor component as set forth in claim 5 wherein said groove is disposed on said inner bearing surface of said outer race.
- 18. A conveyor component as set forth in claim 5 wherein said groove comprises a series of spaced annular grooves.
- 19. A conveyor component as set forth in claim 5 wherein said groove comprises a series of spaced annular flanges.
- 20. A conveyor component as set forth in claim 5 wherein said groove comprises a series of indentations.
- 21. A conveyor component as set forth in claim 5 wherein said groove comprises a series of raised areas.
- 22. A conveyor component comprising:
a race having a bearing surface for relative movement, wherein said bearing surface comprises at least one matrix material selected from the group including phenolic, epoxy, polyurethane, polyetherketone, ultrahigh molecular weight polyethylene, polyimide, polyphthalamide, polyhenylene sulfide, polyesthers and fluoropolymers and at least one additive selected from the group including the super-hard carbides, nitrides and oxides of titanium, boron, tungsten, tantalum, chromium and molybdenum.
