Abstract:
Embodiments of the invention relate to tilting pad bearing assemblies and apparatuses. The disclosed tilting pad bearing assemblies and apparatuses may be employed in downhole motors of a subterranean drilling system or other mechanical systems. In an embodiment, a bearing assembly or apparatus includes a support ring and a plurality of tilting pads. Each tilting pad is tilted and/or tiltably secured relative to the support ring. In some embodiments, one or more of the tilting pads include a plurality of superhard bearing segments assembled to form a superhard bearing surface. One or more seams may be positioned between adjacent superhard bearing segments of the superhard bearing segments. In other embodiments, one or more of the tilting pads may include at least one or only one superhard bearing segment, such as a polycrystalline diamond bearing segment.

Claim (Index 2):
A method of operating a bearing assembly, the method comprising:\n providing a runner and a bearing assembly; wherein the runner includes at least one runner superhard bearing surface comprising a chemically-vapor-deposited carbide material; wherein the bearing assembly includes a support ring and a plurality of tilting pads, each of the plurality of tilting pads includes at least one polycrystalline diamond bearing element having a cemented carbide substrate bonded to a polycrystalline diamond table, the polycrystalline diamond table including a tilting pad superhard bearing surface; and rotating at least one of the at least one runner superhard bearing surface or the tilting pad superhard bearing surfaces of the plurality of tilting pads at a sufficient rotational speed so that the hydrodynamic film develops between the first bearing surface and the second bearing surfaces.
