Abstract

Official abstract text for this publication.

A thrust bearing includes: a thrust plate in a disc shape having an outer diameter and an inner diameter formed by perforating a central portion of the thrust plate; a plurality of bump foils disposed radially on a top surface of the thrust plate; a plurality of top foils in a panel shape covering each of the bump foils, where bottom surfaces of the top foils are in contact with upper ends of the bump foils; and metal blocks radially disposed on the top surface of the thrust plate and formed to be spaced apart from the bump foils. The thrust bearing can be included in an air compressor of a vehicle.

First claim

Opening claim text (preview).

What is claimed is: 1. A thrust bearing, comprising: a thrust plate in a disc shape having an outer diameter and an inner diameter formed by perforating a central portion of the thrust plate; a plurality of bump foils disposed radially on a top surface of the thrust plate; a plurality of top foils covering each of the bump foils, wherein bottom surfaces of the top foils are in contact with upper ends of the bump foils; and metal blocks radially disposed on the top surface of the thrust plate and formed to be spaced apart from the bump foils, wherein each of the metal blocks includes an inclined region having an inclination formed upwardly along a certain distance from the top surface of the thrust plate, and an extension region extended from the inclined region of the metal block to be inclined smaller than the inclination of the inclined region of the metal block. 2. The thrust bearing of claim 1 , wherein each of the top foils includes an inclined portion having an inclination formed upwardly along a certain distance from the top surface of the thrust plate, of which one end is fixed to the top surface of the thrust plate, and an extension portion extended from the inclined portion of the top foil to be inclined smaller than the inclination of the inclined portion of the top foil. 3. The thrust bearing of claim 1 , wherein the metal block is paired with the top foil, the inclined region of the metal block is formed at a position corresponding to the inclined portion of the top foil paired with the metal block, and the extension region of the metal block is formed at a position corresponding to the extension portion of the top foil paired with the metal block. 4. The thrust bearing of claim 1 , wherein the inclination of the inclined region of the metal block is formed to be smaller than the inclination of the inclined portion of the top foil so that a height of the extension region of the metal block is lower than that of the extension portion of the top foil. 5. The thrust bearing of claim 1 , wherein the metal blocks are spaced apart from the bump foils respectively in a direction of the outer diameter of the thrust plate and disposed along the outer diameter of the thrust plate. 6. The thrust bearing of claim 1 , wherein the metal blocks are spaced apart from the bump foils respectively in a direction of the inner diameter of the thrust plate and disposed along the inner diameter of the thrust plate. 7. The thrust bearing of claim 1 , wherein the metal blocks comprise first metal blocks spaced apart from the bump foils in the direction of the outer diameter and disposed along the outer diameter of the thrust plate and second metal blocks spaced apart from the bump foils in the direction of the inner diameter and disposed along the inner diameter of the thrust plate.
