ABSTRACT:
A fluid bearing damper for damping radial motion of a bearing includes a plurality of concentric, circular, thin shims located in an annular damping chamber to present thin, radially stacked damping cavities. A portion of the shims have protruding radial lands that partially define the cavities, carry radial loads through the damper and produce a controlled mechanical centering force as well as serving to ensure replenishment of fluid film cavities.
