A hydrodynamic fluid film bearing has a stationary retaining member (12) having a cylindrical opening (14) to receive for rotation therein a rotatable shaft (16). The inner surface (20) of the opening (14) is lined by a generally cylindrical-shaped foil assembly (18) comprised of a plurality of foil sub-assemblies (24) each comprised of spring foils (26), contact foils (30) and, optionally, inner foils (32). Each foil sub-assembly (24) subtends a rotational segment, less than all, of the inner surface (20), e.g., from about 45 degrees to 120 degrees of r...
A hydrodynamic fluid film bearing comprising: a retaining member having an inner surface which defines a shaft opening within which a rotatable shaft is receivable for rotation; and a foil assembly affixed to and lining the inner surface and comprising a plurality of foil sub-assemblies, the foil sub-assemblies each subtending a rotational segment, less than all, of the inner surface and comprising (i) compliant flat contact foils sandwiched between (ii) spring foils disposed radially outwardly of their associated contact foils and (iii) compliant flat i...
