    Abstract: An electric submersible pump (ESP) with reduced vibration is provided. In an implementation, an ESP section has radial bearings placed at shaft locations of reduced vibration to reduce wear. The locations of reduced vibration are selected to avoid areas of high vibration and vibrational waves that reinforce each other due to structure resonance and natural excitation frequencies. In an implementation, a radial bearing is positioned at a node of reduced vibration of a standing vibrational wave. In an implementation, a succession of multiple radial bearings are spaced at different intervals from each other to avoid conventional even spacing of the bearings that causes standing waves, resonance waves, and vibrational waves at natural excitation frequencies. In an implementation, a span between adjacent radial bearings is selected to spare other adjacent bearings at different spans the effects of vibrations that may extend over a range of excitation frequencies in the ESP section.

  • Patent number: 10190652
    Abstract: A damped automotive driveline component can be propshaft, a bar shaft, a torque tube housing, a power transfer unit (PTU) housing, or a final drive unit (FDU) housing, among other possibilities. The component is equipped with a dampener in order to dissipate vibration experienced during use of the component. The damper includes metal wire strands. Relative movement among the metal wire strand is believed to damp the vibrations.

  • Patent number: 10030734
    Abstract: A load coupling device for a power train including: a rotatable shaft; a first flange on a first end of the shaft, wherein the first flange is adapted to couple to a first rotating shaft of at a torque producing turbine or a torque driven electrical generator; a second flange on an opposite end of the shaft, wherein the shaft is adapted to couple to a second rotating shaft of the other of the turbine and the generator, and an annular ring extending radially outward from the first flange, wherein the mass of the annular ring is selected to shift a torsional natural frequency of the power train away from an operational condition of the power train. Trim masses may be added to make fine adjustments to the torsional natural frequency of the power train.

  • Patent number: 9958003
    Abstract: The present invention relates to a hybrid drive shaft using friction-stir welding and a fabrication method thereof, and more particularly to a drive shaft comprising a metal tube, a composite material layer formed inside the metal tube, and a metal yoke connected to both ends of the drive shaft by means of friction-stir welding so as to make the components simple and lightweight and to enhance the durability, and a fabrication method thereof. The fabrication method comprises the steps of: shaping a composite material sheet; bonding the cylindrical composite material layer to the inside of a metal tube; maintaining the inside of the metal tube in a vacuum state for a given duration; heating the metal tube maintained in the vacuum state in an autoclave; and adjoining a connection member for connecting other parts to the ends of the metal tube.

  • Patent number: 9958027
    Abstract: A vibration damping device in which vibration damping performance of a damper having a chamber holding a rolling member is improved. The vibration damping device is adapted to damp vibrations resulting from a pulsation of torque applied to a rotary member by an oscillating motion of a rolling member connected with the rotary member while being allowed to rotate relatively therewith. The vibration damping device is provided with a casing member enclosing the rolling member, and a sealing member that connects the casing member with the rotary member in a manner such that the rotary member is allowed to rotate relatively with the casing member, while preventing oil from entering into an inner space of the casing member where the rolling member is held to oscillate.

  • Patent number: 9917488
    Abstract: An electric motor includes a stator, a rotor, and weights removably attached to the rotor shell for use in balancing the rotor. The removable weights may be integrally formed with a rotor shell such that the weights and the rotor shell form a unitary, one-piece construction. The removable weights may be substantially uniformly spaced apart around an entirety of the outer perimeter of the rotor shell. In a method of making an electric motor, the stator is coupled to the rotor such that the weights are accessible for selective removal during balancing of the rotor.

  • Patent number: 9909422
    Abstract: The present invention relates to a device for inserting a balancing weight into a rotor of a turbine, that includes an external component and an internal component. The internal component is connected in a helical manner to the external component. The internal component delimits a chamber which has a first and a second opening, a lower surface which is provided with a sealing joint and a cap in order to close in a tight manner the first opening of the chamber. The connection between the external component and the internal component is helical, that is to say, the result of a threading operation. Therefore, the internal component can thus move in a coaxial manner with respect to the external component.
