 US Patent 11761486 Polycrystalline diamond bearings for rotating machinery with compliance

Article

Patent abstract

Methods and apparatus for providing compliance in bearings of rotating machinery are provided. The rotating machinery may include a drive shaft movably coupled within a bearing housing. Compliant bearing assemblies may interface engagement between the drive shaft and the bearing housing, including polycrystalline diamond bearing elements, each with an engagement surface, and an opposing engagement surface of a metal that contains diamond solvent-catalyst.
