초록

A compliant support for an axial thrust air bearing between a shaft and a housing with an annular thrust runner extending radially from the shaft having a runner bearing surface. The housing has a housing bearing surface and an air inlet in communication with a source of pressurized air. An annular foil support sleeve is disposed on the housing bearing surface, having an air foil surface with an array of foils. The foils serve to conduct air from the air inlet forming a pressurized air curtain between the runner bearing surface and foils on the the sleev...
