Kind Code:
An embodiment of the present invention relates to an airfoil thrust bearing (1) provided on various types of turbo devices or air blower devices. More particularly, the purpose of the present invention is to provide the configuration of an airfoil thrust bearing (1) comprising: a front cover (10) that provides a space in which a thrust bearing is seated, the front cover (10) having a coupling portion (110) formed such that the thrust bearing can be selectively attached to/detached from the same; a body ring (310) having a predetermined outer diameter, the body ring (310) being provided such that the same can be selectively attached to/detached from the front cover (10); a top support portion (320) formed in at least one position so as to protrude from the body ring (310) in the center axis direction; a top connecting portion (330) formed to taper by a predetermined angle with regard to the top support portion (320); a top (340) formed to extend from the top connecting portion (330) by a predetermined length while being parallel with and spaced apart from the body ring (310) by a predetermined distance; a bump (350) coupled to a side surface of the top in a predetermined position through spot welding; a thrust portion (30) having a coupling space repeatedly formed between an end portion of the top and a support portion (320) of the next top so as to provide a space corresponding to the area of the top; and a rear cover (20) coupled to the front cover (10) so as to shield the thrust bearing, wherein two or more thrust bearings are rotated by a predetermined angle with regard to the center axis and are then overlapped, thereby completing the same, and the thrust bearings are configured such that the same can be selectively attached to/detached from the front cover (10) through screw fastening.
