Air foil bearing for high temperature cooling

摘要

PURPOSE: An air foil bearing for high temperature cooling is provided to smoothly cooling an air foil bearing because air is supplied through channels forming in a bump foil from an air supply part. CONSTITUTION: An air foil bearing for high temperature cooling comprises a bearing sleeve(110), a plurality of air foils(120), and an air supplying part(130). A rotation shaft(1) is rotatably arranged inside the bearing sleeve. The air foils are arranged in between the bearing sleeve and the rotation shaft. In order to be cooled in the area of the rotation shaft, the air supply part supplies air to the inside of the bearing sleeve in a radial direction of the bearing sleeve or a direction crossing the radial direction.
