description The present invention relates to an apparatus to adjust the stiffness of an air bearing. According to the present invention, the apparatus to adjust the stiffness of an air bearing comprises: a housing having an inner space formed therein; a radial air bearing disposed in the inner space and surrounding the outer circumference of a shaft; a bush disposed in the inner space and surrounding the outer circumference of the radial air bearing; a first elastic body disposed between the housing and the bush; and a second elastic body disposed between the bush and the radial air bearing. Accordingly, an elastic body is disposed between the housing and the bush, or between the bush and the radial air bearing, and arrangement of the upper and lower parts of the bush is adjusted or an elastic groove, a penetration part, and the like are additionally formed, thereby providing an effect of variously setting the stiffness of an air bearing. 본 발명은 에어 베어링의 강성조절장치에 관한 것으로서, 그 구성은, 내부공간이 형성되어 있는 하우징; 상기 내부공간 내에 배치되고, 샤프트의 외면 둘레를 감싸며 배치되는 반경방향 에어 베어링; 상기 내부공간 내에 배치되고, 상기 반경방향 에어 베어링의 외면 둘레를 감싸며 배치되는 부쉬; 상기 하우징과 상기 부쉬의 사이에 배치되는 제1탄성체; 상기 부쉬와 상기 반경방향 에어 베어링의 사이에 배치되는 제2탄성체;를 포함하는 것을 특징으로 하며, 상기의 구성에 따르면, 하우징과 부쉬 사이 또는 부쉬와 반경방향 에어 베어링 사이에 탄성체를 배치하고, 부쉬 상, 하부의 탄성체 배열을 조절하거나 탄성홈, 관통부 등을 추가적으로 형성함으로써, 에어 베어링의 강성을 더욱 다양하게 설정할 수 있는 효과가 있다.
