摘要：
A compliant hydrodynamic gas bearing comprises a nonlinear spring arrangement for supporting a plurality of tilting arcuate pads which hydrodynamically carry radial journal loads. The nonlinear spring support arrangement enables the bearing to provide increasing load-deflection capacity under extreme loads to limit deflection to a predetermined clearance. The spring arrangement provides nonlinear load-deflection capabilities while operating with a designed constant bending stress.
