Abstract
Description
Claims (1)
- 주축의 상단에 고정되는 유체유입공이 형성된 스터브 로터와 유체의 압력에 의하여 전진하는 슬리브에 의하여 유체를 공급하거나 차단할 수 있게 하는 공작기계의 유체공급용 회전조인트에 있어서,카트리지 유니온(15)의 하우징(11)에 내장되어 압축스프링(16)에 의하여 탄력지지 되는 슬리브Ⅰ(17)과, 슬리브Ⅰ(17)에 내장되는 슬리브Ⅱ(18)가 유체의 압력에 의하여 슬라이딩하면서 슬리브Ⅰ(17)을 전진시켜 선단부(19)에 결합된 세라믹팁(22)을 스터브 로터(13)의 세라믹팁(22')과 접촉시켜 기밀을 유지하게 하고, 유체의 압력이 제거되면 압축스프링(16)에 의하여 슬리브Ⅰ(17)과 슬리브Ⅱ(18)가 후퇴하면서 슬리브Ⅱ(18)의 돌출부가 스터브 로터(13)의 유체유입공(24)에 부분삽입되게 구성한 것을 특징으로 하는 공작기계의 유체공급용 회전조인트.
