Description

틈새형 밀폐장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 밀폐장치의 일예를 나타낸 도면으로서 축부재는 고정시키고 벽부재는 회전식으로 한 것이다.
제2도는 제1도의 예를 상세하게 도시한 것으로서 축상의 올레오포빅 피막과 윤활유 및 밀폐용 개스의 흐름을 나타낸 도면.
제3도는 제2도를 더욱 상세하게 나타낸 것으로서 윤활유가 올레오포빅 피막위에서 방울방울 뭉쳐서 밀폐용 개스의 흐름에 실리는 모습을 도시한 도면.
제4도는 본 발명에 의한 밀폐장치의 또 다른 예로서 축부재를 회전식으로 설치하는 한편 고정부재와 회전부재 모두에 올레오포빅 피막을 입혀놓은 모습을 나타낸 도면.

Claims (4)

  1. 축부재, 축부재 둘레로 축선방향으로 길게 최소한 그 축부재 길이 일부에 대하여 틈새가 존재하게끔 둘러싸도록 함과 아울러 그 자신에 대하여 축부재가 또는 축부재에 대하여 그 자신이 고정되게끔 하는 한편 상대적으로 그 나머지 한쪽은 회전할 수 있게끔 설치하는 벽부재, 벽부재에다 상기한 틈새와 통할 수 있게끔 그 틈새부위와 윤활유 공급원 사이에 형성시켜 놓은 윤활유 수집구, 상기한 틈새를 통해서 윤활유 공급원 쪽으로 밀폐 개스를 흘러보내는 밀폐개스 공급장치, 및 윤활유 수집구 주변의 고정부재상에 입혀놓은 올레오포빅 피막으로 구성하여 윤활유가 윤활유 수 집구로 들어와서 고정 부재를 따라서 흐를때 올레오포빅 피막에 의해서 방울져서 밀폐개스의 흐름에 실리도록 함으로써 상기한 틈새 부위로 사실상 들어가지 못하도록 하는 틈새형 윤활유 밀폐장치.
  2. 제1항의 것으로서, 축부재는 고정시키고 벽부재는 회전식으로 설치하여 구성한 틈새형 윤활유 밀폐장치.
  3. 제1항의 것으로서, 벽부재는 고정시키고 축부재는 회전식으로 설치하여 구성한 틈새형 윤활유 밀폐장치.
  4. 제1항의 것으로서, 상기한 수집구 속의 회전 부재상에 올레오포빅 피막을 입혀놓은 틈새형 윤활유 밀폐장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
