摘要： A power tool includes a tool housing and a motor assembly received in the tool housing. The motor assembly has a rear end portion, a front end portion, and a motor output shaft. A transmission housing is coupled to the motor housing with a transmission received in the transmission housing, to which the motor output shaft is drivingly coupled. A partition assembly includes a rear cover covering a rear end portion of the transmission housing that faces the front end portion of the motor and a seal. The rear cover of the transmission housing, the front end portion of the motor, and the seal together define at least a first labyrinth path and a second labyrinth path therebetween configured to inhibit grease or dust migration between the transmission housing and the motor assembly.

摘要： An electrical submersible well pump assembly has a SAW (surface acoustic wave) sensor on a motor shaft. A SAW electronic circuit mounts to the motor housing. The SAW electronic circuit has an antenna closely spaced to the SAW sensor for monitoring torque on the motor shaft. A controller at an upper end of the well supplies power to the motor. A motor gauge unit mounted to a lower end of the motor transmits signals to the controller. A signal line extends from the SAW electronic circuit to the motor gauge unit for transmitting signals from the SAW electronic circuit to the motor gauge unit, and from the motor gauge unit to the controller.

摘要： In the shaft sealing device according to one embodiment, a seal ring includes a machine-interior-side seal ring member, and a machine-exterior-side seal ring member. A ring gap is left between the machine-interior-side seal ring member and the machine-exterior-side seal ring member. A seal gap is left between an inner peripheral surface of the machine-interior-side seal ring member and an outer peripheral surface of the rotary shaft and between an inner peripheral surface of the machine-exterior-side seal ring member and the outer peripheral surface of the rotary shaft. The inner peripheral surface of the machine-interior-side seal ring member is a flat surface that generally follows along the outer peripheral surface of the rotary shaft, and a groove extending along a direction of rotation of the rotary shaft is formed in the inner peripheral surface of the machine-exterior-side seal ring member.

摘要： An electric machine includes a stator, a rotatably mounted rotor interacting with the stator and including a shaft which has an axial borehole. A flow guiding element extends into the axial borehole such as to enable a coolant to flow out of the flow guiding element and into the axial borehole or into the flow guiding element and out of the axial borehole. A slide ring seal seals the shaft with the axial borehole with respect to an element that is rotationally stationary relative to the shaft. When the electric machine is in operation, a value for moisture in a cavity of the electric machine can be determined in a cavity of the electric machine.

摘要： A motor case (10) has connectors (30) fixed at motor case mounting holes (11), and an inverter case (50) has connectors (60) radially movable at inverter case mounting holes (65). The inverter case (50) is mounted on the motor case (10) so that the connectors (30, 60) fit together. A surface seal (45) is disposed on a lower surface of a flange (42) at an outer periphery of a housing (35) of the motor-side connectors (30), and is compressed elastically against an upper surface of the motor case (10) at an outer periphery of the motor case mounting holes (11). A metal pressing member (20) is fixed on the motor case (10) and presses the flange (42). An axial seal (47) is fit on the outer periphery of the housing (35) and is compressed elastically between the outer periphery and an inner periphery of the second mounting hole (65).

摘要： A retrofit method for modifying a radial lead seal assembly of a generator and a radial lead seal assembly of a generator are presented. The radial lead seal assembly seals a radial chamber from an axial chamber. The radial lead seal assembly includes sealing elements disposed around a radial lead to seal an annular space between the radial lead and the radial chamber, a coil spring disposed around the radial lead between the sealing elements and a junction between the radial lead and the axial lead, and a nut. The retrofit method includes removing one or more of the sealing elements to define a radial space between the remainder of the sealing elements and the coil spring. Conical springs are inserted in the radial space and only partially compressed under a radially inward compressive load exerted on the radial lead seal assembly via the nut.

摘要： A motor may include a bearing mechanism including a shaft arranged along a center axis, a sealing member has one-end closed cylindrical shape and a recess receiving a lower portion of the bearing mechanism, a stationary portion including a base defining a part of the housing, and a rotary portion rotating relative to the stationary portion about the center axis. The base has a through hole defined therein so as to have a center aligned with the center axis and pass through the base in an axial direction. The sealing member is fixed in a fixing region defined between an outer circumferential portion of the sealing member and an inner circumferential portion that defines the through hole in the base. The fixing region includes a sealing region where a clearance between the sealing member and the base is closed.
