摘要： A mud motor bearing assembly for use in drilling a hydrocarbon well. The bearing assembly includes a bearing section containing stationary bearing rigs and rotating bearing rings in stacked arrangement. The bearing rings have wedge-shaped projections. The wedge-shaped projections of two adjacent stationary bearing rings form a recess to accommodate the projection of a rotating bearing ring in sliding engagement. The bearing assembly is capable of bearing both radial and axial loads.

摘要： A mechanical part configured to be placed under torque. The mechanical part includes an inner tube having, a corrugated web, and an outer shell. The inner tube has an outer tube circumference, a tube axial direction, and a tube length. The corrugated web has a plurality of peaks and a plurality of troughs, a height measured as a difference between one of the peaks and one of the troughs, and a web length perpendicular to the height and in the tube axial direction. The outer shell has an inner shell circumference, an outer shell circumference, and a shell length. The plurality of troughs is affixed to the outer circumference of the inner tube. The plurality of peaks is affixed to the inner shell circumference of the outer shell. The web length is aligned with the tube length and the shell length.

摘要： A spherical plain bearing comprising an inner ring provided with a spherical outer surface and with lateral surfaces, an outer ring provided with a corresponding spherical inner surface mounted on the outer surface, and a sleeve mounted into a bore of the inner ring. The inner ring comprises at least three part rings which are mounted in contact in the circumferential direction one relative to another. At least one protrusion is provided on an outer surface of the sleeve and extends into a groove formed on the bore of the inner ring. The sleeve leaves the lateral surfaces free of the inner ring.

摘要： This disclosure relates to a method for controlling lubrication of a rotary shaft seal. The method involves providing an apparatus having a bulk lubricating oil reservoir, a rotary shaft that passes through the bulk lubricating oil reservoir, and a rotary shaft seal. The rotary shaft seal has a sealing edge in proximity with the rotary shaft creating a contact zone. The contact zone has a film of lubricating oil. The method also involves increasing the rate of heat flow along the rotary shaft to reduce temperature of the film of lubricating oil in the contact zone. Increasing the rate of heat flow along the rotary shaft is accomplished by using rotary shaft materials of construction having sufficient high thermal conductivity, rotary shaft coatings having sufficient high thermal conductivities, or increasing the surface area of the rotary shaft. This disclosure also relates to a method for controlling heat transfer in a contact zone, and a method for improving performance of an apparatus.
