摘要： A bearing assembly comprises an outer bearing member having a cylindrical bore therethrough and a cylindrical inner bearing member extending coaxially within the bore in the outer bearing member, the inner bearing member having a cylindrical bore therethrough for accepting a rotating shaft. A first conduit is provided for supplying fluid to the bore in the outer bearing member to form a hydrostatic bearing between the inner bearing member and the outer bearing member, the first conduit comprising a passageway through the inner bearing member having four openings into the bore in the outer bearing member, the openings being arranged into pairs, the openings in each pair being in opposing regions of the bore. A second conduit is provided for independently supplying fluid to the bore in the inner bearing member to form a hydrodynamic bearing between the inner bearing member and a shaft located in the bore in the inner bearing member, the second conduit comprising a passageway having two openings into the bore in the inner bearing member, the openings being in opposing regions of the bore.
