A radial bearing assembly is provided. The radial bearing assembly includes polycrystalline diamond elements, each having an engagement surface in sliding engagement with an opposing engagement surface. The opposing engagement surface includes a diamond reactive material. The radial bearing assembly may be deployed in a variety of components and applications, including in rotor and stator assemblies. Also provided are methods of use of the radial bearing assembly, as well as methods of designing the radial bearing assembly.

Polycrystalline diamond radial bearing

A downhole tool for use in a downhole drill string is provided. The downhole tool includes a rotor movably coupled within a stator, and a drive shaft movably coupled within a bearing housing. The drive shaft has a first end coupled with the rotor and a second end coupled with a drill bit. Bearing assemblies interfaces engagement between the drive shaft and the bearing housing, including polycrystalline diamond elements, each with an engagement surface, and an opposing engagement surface of a non-superhard metal.

A roller ball assembly is provided. The assembly includes a primary roller ball supported by a support element that is composed of a superhard material. The assembly includes a cup defining a cavity within which the support element is positioned. A cap is coupled with the cup and positioned to retain the primary roller ball within the cavity. Also, a cup is disclosed for supporting roller halls. Additionally, disclosed are system and apparatus incorporating the assembly, as well as to methods of making and using the same.

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.

Polycrystalline diamond bearings for rotating machinery with compliance

The present disclosure includes sucker rod strings, pipe protectors, and tool joints having polycrystalline diamond elements positioned thereon to interface engagement with other surfaces in downhole applications. The polycrystalline diamond elements can be positioned on sucker rod guides, sucker rod couplers, pipe protectors, and tool joints.

Power transmission systems are provided that include polycrystalline diamond power transmission surfaces that are engaged with diamond solvent-catalyst power transmission surfaces. The power transmission systems may be or include gears, universal joints, or other power transmission systems or components.

Polycrystalline diamond power transmission surfaces

The present disclosure provides for a force breaker assembly. The assembly includes a housing having a first channel, a body within the housing and including an engagement surface. A second channel is formed in the body. A spring is positioned adjacent the body. A snap ring is positioned within the housing and about the body. When a load is applied to the engagement surface that is below a preset limit, the ring remains engaged within the first and second channel, retaining the body in an extended position. When a load is applied to the engagement surface that is at or above the preset limit, the ring is expanded out of the second channel and into the first channel or is compressed out of the first channel and into the second channel, such that the body is forced into a depressed position.
