Abstract
Official abstract text for this publication.
The present disclosure relates to an improved air foil thrust bearing having a reduced number of components and an increased load support area. The improved air foil thrust bearing comprises a base plate and a plurality of foils attached to the base plate, wherein each of the foils comprises a top foil section and a bump foil section connected to and integral with the top foil section.
First claim
Opening claim text (preview).
What is claimed is: 1. An air foil thrust bearing comprising: a base plate; and a plurality of foils attached to the base plate, wherein each of the foils comprises a top foil section and a bump foil section, and wherein the top foil section extends as a continuous piece in a circumferential direction to form the bump foil. 2. The air foil thrust bearing of claim 1 , wherein the bump foil section comprises a plurality of bumps. 3. The air foil thrust bearing of claim 2 , wherein the plurality of bumps protrude towards the top foil section. 4. The air foil thrust bearing of claim 3 , wherein the plurality of foils are arranged on an upper surface of the base plate along a circumferential direction of the base plate. 5. The air foil thrust bearing of claim 4 , wherein the top foil section of one foil is superposed on the bump foils of a circumferentially adjacent foil. 6. The air foil thrust bearing of claim 1 , wherein the top foil section has a flat upper surface. 7. The air foil thrust bearing of claim 1 , further comprising an inclined section formed between the top foil section and the bump foil section of a foil. 8. The air foil thrust bearing of claim 7 , further comprising an attachment section formed between the inclined section and the bump foil section. 9. The air foil thrust bearing of claim 8 , wherein the attachment section is attached to the base plate. 10. The air foil thrust bearing of claim 9 , wherein the attachment section is foldable. 11. The air foil thrust bearing of claim 10 wherein when the attachment section is folded, the top foil section is superposed on the bump foil section. 12. The air foil thrust bearing of claim 11 , wherein, prior to folding, the plurality of bumps protrude away from the top foil section.
