PROBLEM TO BE SOLVED: To provide a compliant foil fluid film thrust bearing of improved structure. SOLUTION: A compliant foil fluid film thrust bearing comprises a thrust disc 24, a fluid foil member 40, spring foil members 42, a thrust plate 28, and a housing thrust surface. The fluid foil member non-rotational arranged adjacent to the thrust disc mounted on the thrust plate and/or housing thrust surface has a surface-releasing channel which induces a reproduced eddy current pattern in the process fluid. A plurality of spring foil members work in cooperation, provide a tilting pad support for the fluid foil member, and enable the fluid foil member to make follow-up after the axial direction movement and tilting motions of the thrust disc. A convex shape effective in terms of hydrodynamics is generated on the surface adjacent to the thrust disc owing to the interaction of the lower layer spring support as the tilting pad and circumferential direction fluid pressure gradient of the process fluid between the fluid foil member and thrust disc 24. |
