  • Tunable viscoelastic neutralizer with oscillating mass on shaft for control of vibrations in pipes in general
    Patent number: 11965580
    Abstract: A dynamic viscoelastic vibration neutralizer for industrial pipes includes a metallic housing, to which the shaft supports are fixed, by screws. The supports of the viscoelastic pieces and the supports of the housing itself, allow the junction of the device with the system to be controlled. An oscillating mass, fixed in the center of a metallic shaft, is supported by the shaft supports. two sets of viscoelastic pieces, are fixed by one of their ends to the supports of the viscoelastic pieces and by the other to the oscillating mass.

  • POWER TRAIN ARCHITECTURES WITH LOW-LOSS LUBRICANT BEARINGS AND LOW-DENSITY MATERIALS
    Publication number: 20200300174
    Abstract: Power train architectures with low-loss lubricant bearings and low-density materials are disclosed. The gas turbine used in these architectures can include a compressor section, a turbine section, and a combustor section. A generator, coupled to the rotor shaft, is driven by the turbine section. The compressor section, the turbine section, and the generator each include rotating components, at least one of the rotating components in at least one of the compressor section, the turbine section, and the generator including a low-density material. Bearings support the rotor shaft within the compressor section, the turbine section and the generator, wherein at least one of the bearings is a low-loss bearing having a low-loss lubricant.

  • MECHANICAL DRIVE ARCHITECTURES WITH LOW-LOSS LUBRICANT BEARINGS AND LOW-DENSITY MATERIALS
    Publication number: 20160047308
    Abstract: Mechanical drive architectures can include a gas turbine having a compressor section, a turbine section, and a combustor section. A load compressor is driven by the gas turbine. A rotor shaft extends through the gas turbine and the load compressor. At least one of the rotating components in one of the gas turbine and the load compressor includes a low-density material. Bearings support the rotor shaft within the gas turbine and the load compressor, at least one of the bearings being a low-loss lubricant bearing.
