  • Viscous/friction damper
    Patent number: 4353604
    Abstract: A friction damper is mounted in series with a viscous damper to accommodate the normal magnitude vibration and the higher magnitude vibration occasioned from a larger imbalance of a jet engine rotor manifested by a bowed rotor and including a loading spring to allow the recentering of said friction damper when the higher magnitude vibrations subside.
    Type: Grant
    Filed: December 11, 1980
    Date of Patent: October 12, 1982
    Assignee: United Technologies Corporation
    Inventors: Michael D. Dulberger, David H. Hibner, Donald C. Moringiello
  • Friction damper
    Patent number: 4337982
    Abstract: This invention relates to dampers for bearings supporting rotors of a gas turbine engine which includes frictionally juxtaposed discs that are supported by a spring that is in parallel relationship thereto.
    Type: Grant
    Filed: December 11, 1980
    Date of Patent: July 6, 1982
    Assignee: United Technologies Corporation
    Inventors: Donald C. Moringiello, Stephen H. Dallmann
  • Damped intershaft bearing and stabilizer
    Patent number: 4046430
    Abstract: A viscous damper for a bearing mounted between coaxially mounted shafts rotating at relative speeds is stabilized by mounting a spring in parallel with the damper so as to raise the natural frequency of one of the shafts.
