Abstract
Articulable joints having diamond bearing surfaces engaged with metal bearing surfaces are provided herein. The articulable joints provide multiple degrees of freedom to components, such as drivelines, and bear loads in multiple directions. The articulable joints include diamond bearing surfaces slidingly engaged with opposing metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst.
Claims21
A power transmission system, the system comprising:
- a driveline, the driveline comprising a shaft having a first end and a second end;
- and a first articulable joint coupled with the first end of the shaft, wherein the shaft is pivotable relative to the first articulable joint;
- wherein the first articulable joint comprises multiple bearing surfaces, the multiple bearing surfaces including a first polycrystalline diamond bearing surface engaged with a first metal bearing surface;
- wherein the first metal bearing surface comprises a metal, the metal containing at least 2 wt. % of a diamond solvent-catalyst based on a total weight of the metal;
- and
- wherein the first polycrystalline diamond bearing surface has a surface finish of 20 μin Ra or less.
3 more elements
The system of 15, further comprising:
- a prime mover coupled with the first articulable joint;
- and
- a driven component coupled with the second articulable joint.
