摘要： In a downhole motor bearing section having a cylindrical mandrel rotatably disposed within a cylindrical housing, a bi-directional thrust bearing is disposed within a four-shouldered annular containment chamber formed partially into the inner cylindrical wall of the housing and partially into the outer cylindrical wall of the mandrel. Under on-bottom loading conditions, thrust loads are transferred through the thrust bearing by the upper shoulder of the housing and the lower shoulder of the mandrel. The radial widths of these two shoulders are both symmetrical about the centerline of the thrust bearing such that on-bottom thrust loads are transferred non-eccentrically to the thrust bearing, thereby avoiding twisting loads on the thrust bearing races, increasing the effective on-bottom load capacity of the thrust bearing and extending its service life.

摘要： An underwater hydroelectric turbine comprises a turbine housing having an inlet and an outlet, a central shaft extending axially inside the turbine housing, a self-contained, sealed front bearing unit for rotationally supporting a front end of the central shaft, and a self-contained, sealed rear bearing unit for rotationally supporting a rear end of the central shaft. The front bearing unit and the rear bearing unit each comprises a self-powered lubricant circulation system that draws a fraction of the mechanical power from rotation of the central shaft to circulate lubricant through each respective bearing unit. The turbine may have an equilibrium chamber for automatically balancing lubricant pressure inside a lubricant-containing chamber of the bearing chambers with ambient water pressure outside the bearing housing.

摘要： A wind turbine is provided having a drivetrain with a gearbox and a gearbox housing, at least one gear stage and an output shaft coupled within the housing. The gear stage exerts an axial thrust force on the output shaft during operation of the wind turbine. A generator includes a generator housing and an input shaft connected to the output shaft of the gearbox. The generator includes a rotor and a stator coupled to the generator housing. The rotor is coupled to the input shaft such that the rotor is positioned radially inward from the stator. At least one bearing is shared between the gearbox output shaft and the generator input shaft, and this bearing carries a portion of the axial thrust force. The generator is skewed to exert an opposing axial thrust force on the input shaft, so that the axial thrust force carried by the bearing is reduced.

摘要： One embodiment of a hybrid vertical axis rotating load carrying bearing with continuously variable operating conditions able to carry surprisingly heavy weight, and occasionally easily able to carry drastically more weight than that; The preferred embodiment has 3 different types of bearings combined to form one ideal bearing. The first type of bearing is a half ball and female sliding bearing. The second type of bearing is a floating bearing that surrounds the sliding bearing. The third type of bearing is rolling bearings. In this preferred embodiment with 3 different types of bearings, the rolling bearings are partially engaged under ideal load weight conditions, and nearly fully engaged under severe load weight conditions. The sliding and floating bearings are always fully engaged into the vertical weight load no matter what the vertical weight load may be.Another embodiment is the hybrid bearing containing two types of bearings; a floating bearing and rolling bearings. In this embodiment, a floating bearing is in the center axis and rolling bearings are located outside the floating bearing, on a larger diameter circle. In ideal operating conditions, the floating bearing will hold nearly all the load, and some of the rolling bearings will engage into the rotating load. In severe conditions, nearly all rolling bearings will engage into the rotating load.

摘要： A thrust bearing assembly for a submersible motor assembly of a submersible pump assembly comprising first and second bearing members or plates and first and second bearing holders contained within a housing. Each bearing plate is in the form of a disk having a bearing surface, and the first and second bearing plates are disposed between the first and second bearing holders with the bearing surfaces in face-to-face contact. The first bearing holder is in the form of a thrust bearing holder, and the second bearing holder is in the form of a gimbal plate. The first bearing plate is adapted to rotate with a rotor shaft of the submersible pump assembly and to impose a thrust load on the second plate, and the second bearing plate is adapted to remain stationary relative to the rotating first bearing plate. Grooves are defined by one or both of the bearing surfaces to allow fluid from a fluid supply to enter between the bearing surfaces to create a fluid film to lubricate and cool the bearing surfaces.

摘要： A rear thrust bearing member is disposed to be in frictional contact with an axial end face of a spindle supported in a cantilever fashion in the neighborhood of and on the rear side of an impeller. Frictional heat that is generated in this part is satisfactorily diffused with a cooling effect provided by the rotation of the impeller in the pump casing and a heat diffusion effect provided by the circulating effect. Thus, a temperature rise of the frictional portions is suppressed, and adverse effects of heat on the surrounding member are prevented.
