Abstract

Official abstract text for this publication.

An air foil thrust bearing includes a base plate and a bump foil structure attached to the base plate. The bump foil structure has two or more bump foils and one or more first rings connecting the two or more bump foils. and the air foil thrust bearing includes a top foil structure attached to the base plate. The top foil structure has two or more top foils and one or more second rings connecting the two or more top foils.

First claim

Opening claim text (preview).

What is claimed is: 1. An air foil thrust bearing comprising: a base plate; a bump foil structure directly attached to the base plate, the bump foil structure having two or more bump foils and one or more first rings connecting the two or more bump foils; and a top foil structure directly attached to the base plate, the top foil structure having two or more top foils and one or more second rings connecting the two or more top foils, wherein the bump foil structure has one or more first positioning recesses in which one or more first positioning protrusions of the base plate are accommodated, wherein one of the one or more second rings has one or more second positioning recesses in which one or more second positioning protrusions of the base plate are accommodated, and wherein the one or more first positioning recesses are radially spaced apart from the one or more second positioning recesses. 2. The air foil thrust bearing of claim 1 , wherein the bump foil structure has two or more connectors, each of which is formed on one side of the corresponding bump foil to be flat. 3. The air foil thrust bearing of claim 2 , wherein the two or more bump foils are individually connected to the first ring through the two or more connectors. 4. The air foil thrust bearing of claim 1 , wherein the one or more first rings are disposed at inner peripheries or outer peripheries of the bump foils. 5. The air foil thrust bearing of claim 1 , wherein the one or more first rings include two first rings individually disposed at inner peripheries and outer peripheries of the bump foils, respectively. 6. The air foil thrust bearing of claim 1 , wherein the top foil structure has two or more connectors, each of which is formed on one side of the corresponding top foil to be flat. 7. The air foil thrust bearing of claim 6 , wherein the two or more top foils are individually connected to the second ring through the two or more connectors. 8. The air foil thrust bearing of claim 1 , wherein the one or more second rings are disposed at inner peripheries or outer peripheries of the top foils. 9. The air foil thrust bearing of claim 1 , wherein the one or more second rings include two second rings disposed at inner peripheries and outer peripheries of the top foils, respectively.
