  • Publication number: 20200393035
    Abstract: A method for controlling a process for manufacturing a bevel gear includes forming, via a first process, a ring gear and determining a first set of parameters associated with the ring gear, and forming, via a second process, the pinion gear, and determining a second set of parameters associated with the pinion gear. The ring gear and the pinion gear are paired, and a single-flank test is executed on the paired ring gear and pinion gear to determine a third set of parameters. The paired ring gear and pinion gear are assembled into a final assembly, and an end-of-line noise/vibration analysis of the final assembly is executed. The noise/vibration analysis, the first set of parameters, the second set of parameters, and the third set of parameters are evaluated, and one of the first process, the second process, the pairing process, and the assembly process are adjusted based thereon.

  • Patent number: 10274040
    Abstract: An active damping system for a driveline includes a prop shaft configured to transmit engine power from an engine to a load, a sealed damper housing, and an active damping fluid contained within the sealed damper housing. A viscosity of the active damping fluid is changeable based on a torsional vibration of the prop shaft. The active damping system further includes a piston fixed to a side of the prop shaft and in communication with the active damping fluid. The piston is configured to rotate about an axis of the prop shaft. The system further includes a viscosity changing unit in communication with the active damping fluid, and a controller operatively connected to the viscosity changing unit. The controller is configured to cause the viscosity changing unit to change a viscosity of the active damping fluid. The viscosity of the active damping fluid changes the torsional vibration.

  • Patent number: 9803742
    Abstract: A radially stacked planetary gear assembly provides improved lubrication fluid flow to the planet gear bearings of an outer planetary gear set which is especially important when the housing or outer planetary gear carrier is stationary. The assembly includes radially aligned or stacked inner and outer planetary gear sets each having a sun gear, a ring gear and a carrier having planet gears in constant mesh with the sun and ring gears wherein the ring gear of the inner gear set is also the sun gear of the outer gear set and the outer carrier is the assembly housing. The sun gear is disposed on a transmission shaft having lubrication passages which aligns with pluralities of radial openings in a hub housing. A circular plate or guide adjacent one side of the housing includes channels which align with the openings and functions as a lubrication director, channeling lubrication from the transmission shaft and the pluralities of radial openings in the housing hub to the outer bearings, shafts and planet gears.

    Inventors: Shoudong Huo, Hai Xu
  • Patent number: 9513389
    Abstract: Acquisition of data by managing crosstalk interference with sector designs and unique sweeps is conducted and the resultant data are processed in 3D common receiver domain to attenuate crosstalk noise while preserving the signals for high source and receiver density acquisition designs. High-amplitude spectral amplitudes are attenuated and inter-ensemble statics or structural time delays are applied to achieve optimum filter performance. If the spectral amplitudes have been attenuated to a level consistent with non-simultaneous acquisition, conventional surface consistent processing can be performed to correct for statics and amplitude variations. A 3-point filter in different frequency bands may then be applied to remove any remaining residual crosstalk noise.

  • Patent number: 9178641
    Abstract: Consistent with the present disclosure, chromatic dispersion is introduced into an optical communication path including multiple segments or spans of dispersion shifted fiber (DSF). The chromatic dispersion generates phase mismatching between optical signals propagating along the optical communication path, i.e., the optical signals are decorrelated, such that mixing products are reduced inmagnitude, and the noise attributable to four wave mixing is correspondingly reduced.
