  • Vibration reducing thrust bearing
    Patent number: 4963039
    Abstract: A thrust bearing for vibration reduction application which isolates the tst shoes so that transmissions of vibrations induced by drag on the thrust shoes are attenuated or avoided. A thrust shoe carrier isolates the thrust shoes from the relatively stationary platform in which the bearing operates by providing a damped spring system with relatively low stiffness in the axial direction and relatively high stiffness in the torsional and radial directions.
