Abstract
The present invention relates to an air foil journal bearing including a bump foil and a top foil, in which one end and the other end of the top foil based on a circumferential direction are disposed with a step difference in a radial direction, and one end of the top foil is disposed radially inward of the other end of the top foil on the assumption that a direction in which the top foil extends from one end to the other end is identical to a rotation direction of a rotor disposed inside the top foil and configured to rotate, such that an additional fluid dynamic pressure is generated in the bearing, and asynchronous vibration components, which affect noise, are suppressed during a high-speed operation, which may improve driving stability.
