ABSTRACT:
A squeeze film damper for dynamically unbalanced rotor includes a bearing on the rotor having a non-rotatable outer race which is vibrateable as a unit with the rotor, on outer plain cylindrical surface on the bearing outer race, an inner plain cylindrical surface on a support around the outer surface concentric therewith when the rotor is aligned on a nominal axis of the support and cooperable therewith in defining a small annulus having a radial depth corresponding to the maximum radial vibratory displacement of the rotor, a groove in the inner cylindrical surface of axial length of between about 1/2 and 2/3 of the axial length of the small annulus and cooperable with the outer plain surface in defining a large annulus having a radial depth of at least three times the small annulus radial depth, the groove being axially symmetrical with respect to the small annulus, and means for maintaining the small and large annuli filled with fluid under pressure.
