A rotating force transmitting mechanism has a rotating member supported on a base plate. The base plate is formed with a bearing part in a bottomed cylindrical shape protruded by extruding. The rotating member is formed with a cylindrical rotating shaft part capable of fitting to the bearing part. The rotating member is supported on the base plate such that the rotating shaft part rotates while sliding with the bearing part.

A composite bearing comprising a densified portion, wherein a hole location is positioned at the approximate center of said densified portion; and a plurality of filament tendrils, wherein the plurality of filament tendrils are configured to wrap around the hole location to create a U shape.

A resin composition for a sliding member includes 75% to 97% by mass of a polyacetal resin; and, as additives, 2% to 20% by mass of an ultra-high-molecular-weight polyethylene resin, 0.01% to 3% by mass of a copolymer of ethylene and ,-unsaturated carboxylic acid, and 0.5% to 3% by mass of a lubricant.

Cutting elements for earth-boring tools may include a polycrystalline table attached to a portion of a first substrate on which the polycrystalline table was formed. The portion of the first substrate may exhibit a thickness less than a thickness of the first substrate before a remainder of the first substrate was removed to form the portion of the first substrate. Another substrate may be attached to the portion of the first substrate, the portion of the first substrate being interposed between the polycrystalline table and the other substrate. Earth-boring tools may include such cutting elements secured to bodies of the earth-boring tools. Bearings for earth-boring tools may include a polycrystalline table attached to a portion of a first substrate on which the polycrystalline table was formed, the polycrystalline table defining a contact surface. Another substrate may be attached to the portion of the first substrate.

Embodiments of the invention are directed to bearing assemblies configured to effectively provide heat distribution from and/or heat dissipation for bearing element, bearing apparatuses including such bearing assemblies, and methods of operating such bearing assemblies and apparatuses. In an embodiment, a bearing assembly includes a plurality of superhard bearing elements distributed about an axis. Each superhard bearing element of the plurality of superhard bearing elements has a superhard material including a superhard surface. Additionally, a support ring structure that includes a support ring that supports the plurality of superhard bearing elements and a thermally-conductive structure in thermal communication with the superhard table of each of the plurality of superhard bearing elements. The thermally-conductive structure has a higher thermal conductivity than the support ring of the support ring structure.

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.
