Abstract: Disclosed herein is an air foil bearing capable of adjusting stiffness of single bumps by varying widths of the single bumps. Since the bumps have the same height in an initial stage, a wedging effect is implemented only when a load is applied thereto by an oil film. Therefore, the air foil bearing is advantageous in terms of height management thereof. In addition, it is possible to stably dampen shocks applied in the direction of rotation of a rotor, to improve a support capability, and to reduce shocks due to damping. Therefore, it is possible to enhance durability of the air foil bearing.

Abstract: Air compressor for a vehicle having improved internal cooling efficiency by ensuring a circulation flow of compressed air for internal cooling and allowing the compressed air to sufficiently flow. The air compressor comprises: a housing with a compression unit for introducing and compressing air from outside; a motor unit which includes a rotor and a stator, and drives the compression unit to rotate according to the rotation of the rotor; a bearing unit supporting the rotor to be rotatable; a cooling circulation flow path formed inside the housing for moving, in an axial direction, some of the air compressed in the compression unit and circulating the air to the compression unit; and a bypass flow path which receives some of the air passing through the cooling circulation flow path and bypasses a partial region of the bearing unit to join the cooling circulation flow path.

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.
