  • Patent number: 9803427
    Abstract: 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.

  • Patent number: 9611885
    Abstract: Embodiments to bearing apparatuses for placement into a borehole containing a drilling fluid in which the apparatus is configured for transferring heat to the drilling fluid from a lubricating fluid substantially sealed within the apparatus. The apparatus includes a substantially sealed housing, first and second bearing assemblies disposed about a rotatable shaft extending through the housing, where the bearing assemblies are within the substantially sealed housing. Each bearing assembly includes superhard bearing elements. One bearing assembly is fixed relative to the shaft so as to rotate therewith, while another bearing assembly is fixed relative to the housing. In an embodiment, a lubricating fluid for lubricating the superhard bearing elements may circulate from within a circulation cavity of the housing or shaft between the superhard bearing elements, and be recirculated back into the circulation cavity. In other embodiments, the lubricating fluid may not be recirculated.
