摘要： An electric motor includes a stator, a housing supporting the stator and having a bearing seat with an inner surface and an inner end, a bearing having an outer surface, a shaft rotatably supported by the bearing, and a rotor supported by the shaft. The motor also includes a tolerance ring having an interior surface, an exterior surface disposed against the bearing seat inner surface, and a plurality of elastic corrugations. Each of the elastic corrugations projects radially from the interior surface, defining a shoulder section disposed between the bearing and the inner end of the bearing seat.

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： 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： A method of non-destructively identifying and characterizing defects in a rotary drill component is provided. The method includes providing a drill component and an ultrasonic test system including a phased array ultrasonic transducer (PAUT). The method also includes acoustically coupling the PAUT to a surface location, transmitting focused ultrasonic acoustic waves at the location into the PAUT and recording a reflected acoustic response corresponding to a portion of a predetermined volume of a microstructure of the component associated with the location on the surface. The method also includes storing the response and moving one of the transducer or the component to a plurality of unique locations representative of the predetermined microstructure and repeating these steps. The method also includes processing the responses and providing an output signal to an output device configured to provide an output indicative of differences in the output signal within the predetermined volume of the microstructure.

摘要： An earth boring bit has thrust faces with one of the thrust faces being at least partially tilted relative to the other. The bit has a cone rotatably mounted to a bearing pin of the bit body. The thrust faces are in the cone and on an end of the bearing pin. One of the thrust faces is completely flat and perpendicular to the axis of the bearing pin. The other thrust face has a tilted portion that is at a skewed angle relative to the axis. The tilted portion creates converging and diverging zones between the thrust faces.
