Title:
AIR FOIL THRUST BEARING
Document Type and Number:
WIPO Patent Application WO/2023/128224
Kind Code:
A1
Abstract:
An air foil thrust bearing of the present invention comprises a bump foil, and a top foil stacked at a position corresponding to the bump foil so as to cover the bump foil, wherein the bump foil and the top foil are formed and disposed such that the outer diameter of the top foil is formed to be larger than the outer diameter of the bump foil in the radial direction and, when a rotor rotates, a portion, in which the pressure of an air film between a thrust runner and the top foil is high, coincides with an area in which the bump foil is present. Accordingly, since friction in the outermost area of the top foil is reduced in the radial direction, durability is improved, and since air pressure is relatively evenly distributed, load bearing capacity is improved.
