摘要： Aspects of the disclosure can relate to an apparatus including a first member having a first bearing surface formed from a hard material (e.g., a diamond-based material, such as a polycrystalline diamond material), and a second member coupled to an input shaft to translate (e.g., rotate, slide, etc.) with respect to the first member. The second member has a second bearing surface formed from a hard material, and the second bearing surface is to bear against the first bearing surface. In embodiments of the disclosure, the first and second members can be for devices including, but not necessarily limited to: solenoids, generators and/or motors (e.g., out-runner radial flux generators, axial flux generators, radial flux generators/motors, roller vane motors, etc.), gearboxes, rotary data swivels, digital actuators, filters (e.g., inner rotating filters), valves (e.g., proportional valves), sensors (e.g., pressure differential sensors), and so forth.

摘要： A mechanical bearing includes a hard bearing element and a support element affixed to the hard bearing element, with a joining element between the hard bearing element and the support element, the joining element being more flexible than the hard bearing element and the support element.

摘要： A drill bit may include a bit body and at least two cones assemblies including at least two drive cylinders having at least two cones. The at least two cone assemblies are mounted on the bit body. The drill bit may also include an indexing mechanism coupled to the bit body and configured to rotate and lock at least one drive cylinder. A method of operating the drill bit may include providing fluid to the drill bit, rotating the drill string to drill formation, moving the indexing mechanism an axial distance within a central chamber of the drill bit, rotating the at least two indexable structures as the indexing mechanism moves, and locking the at least two indexable structures.

摘要： Interfacing surfaces of adjacent tiles in a downhole tool may combine to form a tortuous path therebetween. In various embodiments, this tortuous path may run generally parallel and/or perpendicular to a top surface of the tiles. One example of such a tortuous path may be created by a protrusion extending from an interfacing surface of one of the tiles that may fit snugly within a cavity receding into an interfacing surface of another of the tiles.
