    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.

    摘要: A bearing structure which incorporates the advantages of a hydrodynamic film and of a hydrostatic squeeze film. The structure uses an inner elongated cylindrical bearing member with a hydrodynamic bearing therein, and an outer bearing member axially encompasses the inner bearing member. Passageways and adjacent surface on such members establish fluid flow paths, hydrostatic pockets and squeeze film areas to support such inner bearing member.

    摘要: Apparatus is provided to measure the amplitude and frequency of dynamic force exerted by a rotating shaft on an adjacent non-rotating bearing. The apparatus includes two force probes operatively mounted on the bearing to sense force components in two perpendicular directions. A piezo-electric load cell in each force probe senses the frequency and a proportional amount of the amplitude of the force component in its direction, and converts such sensed frequency and amplitude into an electrical signal. The sensed amplitude in each direction is calibrated to actual amplitude. The calibrated signals from the two force probes are supplied to an oscilloscope to display a composite representation of such dynamic force in a plane including the two directions. In use, the apparatus performs a novel method of measuring such dynamic force.
