Abstract
A squeeze film damper for the high temperature environments includes a fixed journal on a support, a floating journal on a rotating shaft, a damping ring in an annular chamber between the fixed and floating journals, and a pair of metal bellows straddling annular exposed channels defined at a pair of clearance gaps between the fixed and floating journals. The metal bellows are welded to the fixed and floating journals on opposite sides of the exposed channels and filled with high temperature resistant viscous fluid. The damping fluid flows to the damping chamber through the annular channels and the clearance gap between the fixed and floating journals.
