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.
