초록

A hydrodynamic fluid film bearing assembly has a stationary retaining member defining a central opening and having an inner surface lined by a foil assembly comprised of a plurality of foil subassemblies. Each foil subassembly comprises a first compliant foil, a second compliant foil, and a spring foil, and subtending a rotational segment, less than all, of the inner surface of the retaining member. The complaint foils and the spring foil of each foil subassembly are held within the retaining member in such a way that sliding travel of one compliant foil...
