Abstract
A thrust bearing assembly is provided, including a thrust ring defining a thrust face and an opposing thrust ring defining an opposing thrust face. At least one polycrystalline diamond element is coupled with the thrust face and defines an engagement surface. The opposing thrust ring includes a diamond reactive material. In operation, the engagement surface is in contact with the opposing thrust face. Also provided are methods of making, assembling, and using the same, as well as to systems and apparatus including the same.
Claims35
A thrust bearing assembly comprising:
- a thrust face comprising a polycrystalline diamond element, the polycrystalline diamond element having an engagement surface thereon;
- and
- an opposing thrust face comprising a diamond reactive material, wherein the engagement surface is engaged with the opposing thrust face.
A method of bearing axial load, the method comprising:
- engaging a thrust face with an opposing thrust face, wherein the thrust face includes a polycrystalline diamond element coupled therewith, the polycrystalline diamond element having an engagement surface thereon, wherein the opposing thrust face comprises a diamond reactive material, and wherein the engagement surface is engaged with the opposing thrust face.
A thrust bearing assembly comprising:
- a thrust ring defining a thrust face;
- a polycrystalline diamond element coupled with the thrust face, the polycrystalline diamond element defining an engagement surface;
- and
- an opposing thrust ring defining an opposing thrust face, wherein the opposing thrust ring comprises a diamond reactive material, and wherein the engagement surface is engaged with the opposing thrust face.
An assembly comprising:
- an engagement surface comprising polycrystalline diamond;
- and
- an opposing engagement surface comprising a diamond reactive material, wherein the engagement surface is slidably engaged with the opposing engagement surface.
