摘要： Bearing components, bearing assemblies and related methods are provided. In one embodiment, a bearing element includes a base layer and a polycrystalline diamond (PCD) layer comprising a plurality of PCD elements coupled with the base layer wherein each PCD element comprising a substrate and a diamond table. The plurality of PCD elements may be fit together to form a substantially continuous bearing surface. For example, the diamond tables may exhibit substantially square or rectangular geometries that are fit together to define the bearing surface. In other embodiments, the bearing elements may be spaced apart from one another. In other embodiments, the bearing element may include a single PCD element formed from a prefabricated PCD compact or cutting tool blank. Various bearing assemblies may incorporate such a bearing element including, for example, thrust bearings, journal bearings, and tilting pad bearing assemblies.

摘要： Embodiments relate to tilting superhard bearing element bearing assemblies and apparatuses. The disclosed assemblies/apparatuses may be employed in downhole motors of a subterranean drilling system or other mechanical systems. In an embodiment, a bearing assembly may include a support ring and a plurality of superhard bearing elements each of which is tilted and/or tiltably secured relative to the support ring and distributed circumferentially about an axis. Each of the superhard bearing elements includes a bearing surface and a base portion. The base portion of the at least one of the superhard bearing elements may include a tilting feature configured to allow the at least one of the superhard bearing elements to be tiltable about a tilt axis. The bearing assembly includes retaining features that secure the superhard bearing elements to the support ring.
