Definitions

  • the rotor and stator are coaxially or eccentrically arranged.
  • the present invention also relates to a combination bearing having a main bearing formed as a gas bearing and seal, and an auxiliary bearing being suitable for both radial and thrust directions in rotating machines.
  • Figure 5 shows a schematic view of a combination bearing according to another embodiment of the present invention wherein the auxiliary bearing is a ball bearing provided with flow guiding means,
  • Figure 7 shows a schematic view of a combination bearing according to another embodiment of the present invention wherein the auxiliary bearing is a cylindrical bushing provided with flow guiding means,
  • Figure 8 shows a schematic view of a combination bearing according to another embodiment of the present invention wherein the main bearing is provided with a first and a second main bearing surface
  • Figure 9 shows a schematic view of a combination bearing according to another embodiment of the present invention wherein the main bearing is provided with a first and a second main bearing surface
  • Figure 10A-C shows a schematic cross sectional view of a combination bearing according to another embodiment of the present invention wherein the auxiliary bearing is a foil bearing.
  • the combination bearing is provided as an axial bearing formed as a cylindrical disc on the rotor which bears against an associated portion of the stator, whereby a gas film may be formed with stiffness and damping according to the same principle as in a radial bearing having desired dynamic stiffness and damping (not shown in figures).
