Abstract
The invention relates to a foil bearing for high speed rotation such as a turbocharger, a high speed centrifugal separator or the like. The foil bearing according to the present invention can form at least three wedge-shaped spaces between the rotary shaft and the top foil along the direction of rotation of the rotary shaft. The rotary shaft can be supported by at least three portions of air sucked in the wedge-shaped spaces so that when the rotary shaft is rotated at a high speed, the axial center thereof is kept more adjacent to that of the top foil at all times based on the wedge effect by the air.
