Abstract:
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.
