Rotary drill bits may include one or more cutting element assemblies which include a cutter and a mounting system. In one embodiment, the mounting system includes a housing, a first bearing component disposed within the housing, and a second bearing component associated with the cutting element. In certain embodiments, the bearing components may comprise a table of superhard material bonded with a substrate. In one or more embodiments, the bearing components may include bearing surfaces that are arcuate. For example, the bearing surfaces may be substantially spherical (a portion of a sphere). The bearing components may be arranged to act as a radial bearing as well as a thrust bearing for the cutting element, enabling the cutting element to rotate about a longitudinal axis of the cutter, relative to the housing, while also enabling the longitudinal axis of the cutter to be displaced (change angles) relative to the housing.

Cutting insert assemblies and related systems and methods

Rotary drill bits may include on or more cutting element assemblies which include a cutter and a mounting system. In one embodiment, the mounting system includes a housing, a first bearing component disposed within the housing, and a second bearing component associated with the cutting element. In certain embodiments, the bearing components may comprise a table of superhard material bonded with a substrate. In one or more embodiments, the bearing components may include bearing surfaces that are arcuate. For example, the bearing surfaces may be substantially spherical (a portion of a sphere). The bearing components may be arranged to act as a radial bearing as well as a thrust bearing for the cutting element, enabling the cutting element to rotate about a longitudinal axis of the cutter, relative to the housing, while also enabling the longitudinal axis of the cutter to be displaced (change angles) relative to the housing.

Systems and methods for mounting a cutter in a drill bit

Embodiments disclosed herein are directed to a superabrasive compact including one or more superabrasive cutting portions or segments, rotary drill bits including one or more superabrasive compacts, and related methods (e.g., methods of fabricating and/or operating the superabrasive compacts). For example, the superabrasive compact may include polycrystalline diamond that may form at least a portion of a working surface of the superabrasive compact.

Multi-part superabrasive compacts, rotary drill bits including multi-part superabrasive compacts, and related methods

Tilting pad bearing assemblies and apparatuses are disclosed herein. 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.

Bearing apparatus including tilting pads

Embodiments disclosed herein are directed to bearing assemblies that include integrated lubrication, bearing apparatuses including such bearing assemblies, and related methods. For example, a lubricated bearing assembly may include a lubricant that may lubricate the bearing surface thereof during operation of the lubricated bearing assembly and/or bearing apparatus including the lubricated bearing assembly.

Bearing assemblies including integrated lubrication, bearing apparatuses, and methods of use

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.

In an embodiment, a bearing assembly may include a support ring to which one or more superhard bearing elements may be mounted. The support ring may include one or more relief features configured to reduce residual stresses in the superhard bearing elements that are induced by brazing the superhard bearing elements to the support ring, operational loads, other processes, or combinations of the foregoing. Reducing the residual stresses in the superhard bearing elements may help prevent damage to the superhard bearing elements. The bearing assembly may be used in subterranean drilling systems and/or other types of systems.

Bearing assemblies, apparatuses, and related methods of manufacture

A superabrasive element includes at least one superabrasive table including at least one coupling projection having a narrow portion and a wide portion having a greater width than the narrow portion. The superabrasive element includes a substrate defining at least one coupling recess, the at least one coupling recess extending from a narrow portion to a wide portion. At least a portion of the at least one coupling projection is disposed in the coupling recess and the at least one coupling projection and the at least one coupling recess mechanically couple the at least one superabrasive table to the substrate. A drill bit includes a superabrasive element having a superabrasive table.

Superabrasive elements, drill bits, and bearing apparatuses

Embodiments disclosed herein relate to superabrasive compacts having a metallic member disposed between a superabrasive body and a substrate; and drill bits and methods of making the same.
