AIR FOIL BEARING HAVING DIVIDED STRUCTURE

摘要

The present invention provides an air foil bearing having a division structure including: a top foil surrounding a rotating shaft to form an air layer between the rotating shaft upon rotation of the rotating shaft so that rotating shaft floats and including a fixed portion protruding from an outer peripheral surface; a bump foil surrounding the top foil to reduce vibration of the rotating shaft; a first housing to cover a part of the bump foil and formed with a fixed groove capable of receiving the fixed portion; and a second housing to cover another part of the bump foil and to press the fixed portion upon coupling of the first housing so that the top foil is fixed.
