Assembly for a bearing and methods of making and using the same
An assembly comprising: a core in the form of a toroid; and at least one washer overlying the core, the washer comprising a polymer, wherein the washer has an arcuate cross-section so as to have a shape complementary to the core.
1. An assembly comprising:
a core in the form of a toroid; and
a first washer and a second washer each overlying the core, each washer comprising a polymer and a substrate comprising a metal underlying the polymer, wherein each washer has an arcuate cross-section so as to have a shape complementary to the core, and wherein the first washer overlies the core on a first axial end, and the second washer overlies the core on a second axial end relative to a central axis of the assembly.
2. The assembly of claim 1 , wherein at least one of the first or second washers has a half-round cross-sectional shape.
3. The assembly of claim 1 , wherein the core is at least partially torus-shaped.
4. The assembly of claim 1 , wherein at least one of the first or second washers has a radius of curvature of between 1.6 mm to 900 mm.
5. The assembly of claim 1 , wherein the core is solid.
6. The assembly of claim 1 , wherein the core comprises a metal, a polymer, or a combination thereof.
7. The assembly of claim 1 , wherein the polymer comprises a polyketone, a polyaramide, a polyimide, a polyetherimide, a polyamideimide, a polyphenylene sulfide, a polyphenylene sulfone, a fluoropolymer, a polybenzimidazole, a derivation thereof, or a combination thereof.
8. The assembly of claim 1 , wherein at least one of the first race or the second race comprises a metal.
9. The assembly of claim 1 , wherein at least one of the first or second washers has a spring rate of at least 10 N/mm.
10. The assembly of claim 1 , wherein at least one of the first or second washers comprises a notched region free of polymer.
11. An assembly comprising:
an outer component;
a shaft, wherein the shaft extends through the outer component;
first and second races disposed in the outer component;
a core in the form of a toroid; and
a first washer and a second washer each overlying the core and having a shape complementary to that of the core, each washer comprising a polymer and a substrate comprising a metal underlying the polymer, wherein the first washer, second washer and the core are disposed between the first and second races, and wherein the first washer overlies the core on a first axial end, and the second washer overlies the core on a second axial end relative to a central axis of the assembly.
12. The assembly of claim 11 , wherein the first race and the second race substantially enclose the core and at least one of the first or second washers.
13. The assembly of claim 11 , wherein at least one of the first race or the second race are machined into the outer component.
14. The assembly of claim 11 , wherein the first race and the second race are located at a first axial end of the outer component.
15. The assembly of claim 11 , wherein the first race and the second race are located at a second axial end of the outer component.
16. The assembly of claim 11 , wherein the assembly further comprises a secondary first race and a secondary second race, wherein the first race and the second race are located at a first axial end of the outer component, and wherein the secondary first race and the secondary second race are located at a second axial end of the outer component.
