    摘要： The present invention discloses a bearing damping system for damping vibrations and conducting heat from vibration-producing, heat-generating devices, an evacuated energy storage system including such a bearing damping system for damping vibrations produced by the rotating shaft and conducting heat from bearings and/or bearing assemblies; and a method for damping vibrations and conducting heat from vibration-producing, heat-generating devices. In one aspect of the present invention, the system includes one or more flexible bearing dampers in combination with one or more heat transferring rosettes. The flexible, e.g., elastomeric, bearing dampers minimize the rigid body critical velocity, which further minimizes the amplitude of the vibrations so that relatively high damping energy is required. The heat transferring rosettes comprises a flexible thermally conductive member that transfers heat by conduction from the bearings, bearing assemblies and/or heat generating devices to a remote heat sink. Preferably, the flexible thermally conductive member comprises a first end of a thermally conductive member that is thermally coupled directly to the heat-generating device, a second end f a thermally conductive member that is thermally coupled directly or indirectly to the remote heat sink and a third conductive member therebetween.

    摘要： A dual shaft rotating assembly typically used in aircraft engines is provided with a stable intershaft squeeze film damper for reducing vibration. The assembly includes a housing, a first shaft rotatable about an axis of rotation, a second shaft concentric with the first shaft and rotatable about the same axis of rotation, bearings for supporting each of the shafts from the housing, a squeeze film damper positioned between the shafts and including an annular region containing an oil film for attenuating vibration, and apparatus for maintaining the damping fluid stationary relative to the housing. The squeeze film damper includes an inner ring and an outer ring which define the annular region between them. A first intershaft bearing is coupled between the first shaft and the inner ring, and a second intershaft bearing is coupled between the second shaft and the outer ring. The inner and outer rings are maintained stationary by squirrel cages coupled to the housing. The stationary oil film provides stable damping for all practical rotating speeds of the shafts.
