摘要： An electric submersible pump is provided which has improved vibrational characteristics relative to conventional electric submersible pumps. The improved electric submersible pumps comprise an electric motor mechanically coupled to a pumping section. The improved vibrational characteristics of the electric submersible pump are attributed to the presence of one or more rotor bearings selected from the group consisting of herringbone patterned rotor bearings, pressure dam rotor bearings, circumferential groove rotor bearings, and combinations of two or more of any of the foregoing rotor bearings.

摘要： An X-ray tube is provided. The X-ray tube includes a bearing configured to couple to an anode. The bearing includes a stationary member, a rotary member configured to rotate with respect to the stationary member during operation of the X-ray tube, and a support feature configured to minimize bending moment along a surface of the stationary member to reduce deflection of the stationary member relative to the rotary member due to radial loads during operation of the X-ray tube.

摘要： A hermetically sealed damper assembly includes a sealed damper housing, a plunger, and a load transferring member coupled to the plunger. The sealed damper housing includes a body having a cavity and a resistive flow path defined therein. The cavity and resistive flow path are filled with a viscous fluid. The body includes a plurality of springs integrally formed therein. The plunger is disposed within the cavity, and separates the cavity into a first control volume and a second control volume. The resistive flow path provides fluid communication between the first and second control volumes. The plunger is coupled to the damper housing by the plurality of springs such that the springs provide a restorative force to the plunger. The load transferring member is configured to transmit mechanical loads to the plunger.
