摘要： An assembly including an electric motor, a load, and a retainer. The electric motor can include a shaft that defines a first cross-section that is non-circular and substantially normal to the shaft axis. The load can include a rotating member that defines a bore and first and second apertures in communication with the bore. The bore can be configured to receive at least a portion of the shaft. An opening of the bore can be fully enclosed by a continuous portion of the rotating member. A portion of the bore can define a second cross-section that is non-circular and that corresponds to at least a portion of the first cross-section. The retainer can extend through the first and second apertures and engage the shaft and thereby substantially prevent axial movement of the shaft relative to the rotating member during normal operation of the electric motor.

摘要： A rolling cone earth boring bit has a diverter and an arcuate segment located between the bit leg and the back face of the cone to divert debris from the seal gland area. The diverter has an oblong or oval base that inserts into a mating hole in a last machined surface of the bit. The diverter has a head that is wedge-shaped and protrudes from the hole into a clearance between the back face and the last machined surface. The head has an inner side that is spaced from an annular wall of the back face by a small uniform clearance. The head has an outer side that is oblique to the annular wall of the back face region to divert debris from the clearance. The segment is spaced from the diverter and is concentric to an axis of the bearing pin.

摘要： An assembly controls the liquid level in a vessel in which a submersible pump is disposed. The assembly has a switch housing and a float housing, arranged proximate to each other. A switch in the switch housing selectively energizes a motor associated with the pump. When a float disposed in the float housing moves in response to a change in the liquid level of the vessel, the movement is coupled to the switch by a pair of magnets arranged in attractive relationship to each other. One of the magnets is in the switch housing and the other is in the float housing. The magnets interact by providing force fields that acts through a wall that separates the switch housing and the float housing. A lever on which the switch housing magnet is positioned tilts the magnets away from alignment as they approach each other, reducing the increase in attractive force therebetween.

摘要： Downhole tool bearings are provided with diamond enhanced materials. The diamond enhanced materials comprise diamond grains in a matrix of tungsten or silicon carbide or a silicon bonded diamond material. A brazed diamond grit or diamond particles coated with a reactive braze may be utilized for bearing applications. Bearing rings for use in downhole tools may be formed at least in part with the diamond enhanced material. In one embodiment, the bearing rings may be used in a positive displacement motor. In additional embodiments, the bearing rings may be used in a submersible pump.
