The present invention relates to an air foil journal bearing in which air is introduced between a foil and a rotor rotating at high speed and generates pressure to support a radial load of the rotor and allow the rotor to rotate smoothly, and more particularly, to a housing fixing structure of an air foil journal bearing that improves durability against external impact or vibration by restricting an axial movement of a bump by means of two opposite ends of the bump and a top foil fixing portion.

Housing fixing structure of air foil journal bearing

An air compressor having a housing; a rotating shaft extending in the longitudinal direction inside the housing; a compression unit disposed in front of the rotating shaft and rotated by the rotating shaft to compress and discharge air that flows in; a motor unit which rotates the rotating shaft; a control board which controls the motor unit; a filter unit which supplies external electrical power to the control board and filters the noise of the electrical power; and a bus bar assembly which transfers the electrical power from the control board to the motor unit.

Air compressor

The present invention relates to an air compressor for a vehicle and, more specifically, to an air compressor for a vehicle wherein the entire operation of the air compressor may be stabilized by a cooling unit in which a portion of the compressed air that moves through a connection pipe conveying primarily compressed air exchanges heat with a cooling water flowing part to cool the driving unit.

Air compressor for vehicle

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.

The present invention relates to a compressor and, more specifically, to an air compressor for a vehicle, which can support a rotor disk and form a cooling flow channel by a first cover and a second cover, and thus can improve cooling efficiency while increasing manufacturability.

A vehicle air compressor including a shaft provided with an impeller disposed at one side thereof and a runner disposed at the other side thereof, a motor configured to rotate the shaft, a trust bearing which supports the shaft in a longitudinal direction of the shaft and of which a surface is disposed adjacent to a surface of the runner, wherein a cooling hole for cooling air between the trust bearing and the runner is disposed in the trust bearing.

Air blower for vehicle

The present invention relates to an air foil journal bearing including a bearing housing having a hollow, in which a rotor is arranged, and a pair of top foils with different lengths formed inside the hollow, thereby enhancing assemblability since the lengths are reduced and increasing stability at the time of high speed rotation through position adjustment of a slot to which the top foils are inserted.
