초록

A compliant foil hydrodynamic fluid film radial bearing is disclosed which is comprised of a cylindrical rotor, fluid foil(s), spring foil(s), and a foil retaining cartridge. The cartridge has circumferentially undulating cam shaped lobes or has circumferential ramps and joggles that induce the spring and fluid foils to form converging fluid-dynamic wedge channels which compress and pressurize the process fluid and diverging channels which draw in makeup fluid. A spring foil is formed as a thin, flat sheet having chemically etched slots of a pattern that...
