Summary:PURPOSE: To provide a spindle device offering simple construction permitting a reduction in power loss of a spindle and in output power of a motor and giving cooling effect thereto as well. CONSTITUTION: The spindle device for a machine tool for rotatably supporting the spindle in a housing via bearings 3a, 3b, 4 comprises a helium circulation system for introducing helium having smaller density and resistance to a fluid than air from a helium supply port 28 to a gap in the outer periphery of the spindle in the housing 2 and discharging it from a helium discharge port 29 to the outside, whereby the spindle 5 is rotated under a helium atmosphere. 공작 기계의 스핀들 장치는 베어링을 통해 하우징 내에서 회전 가능하게 지지되는 주 스핀들을 포함한다. 헬륨 순환 시스템이 하우징 내부의 주 스핀들의 외주연 상의 간극 내부의 헬륨 공급 포트를 통해 공기보다 밀도 및 유압이 낮은 헬륨을 도입시키고, 헬륨 배출 포트를 통해 외부로 헬륨을 배출시키기 위해 제공된다. 주 스핀들은 헬륨의 환경 내에서 회전된다. 주 스핀들은 구조면에서 간단하지만, 주 스핀들의 동력 손실을 최소화시키고 모터 동력을 감소시키며, 또한 냉각 효과를 제공할 수 있다.
