Description

베어링장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도∼ 제 3 도는 본 발명의 일 실시예를 표시한 것으로서, 제 1 도는 베어링 부재를 단면으로 해서 표시한 정면도, 제 2 도는 단면 정면도, 제 3 도는 회전 축이 편심되었을 때의 둘레방향의 압력분포도, 제 4∼제 6도는 본 발명의 제 2 실시예를 표시한 것으로서, 제 4 도는 베어링 부재를 단면으로 해서 표시한 정면도.

Claims (2)

  1. 축과 이축을 상대 회전 자재하게 지지하는 부재의 서로 대향하는 원통면으로 이루어진 원통 베어링 면사이에 공기, 기름 등의 윤활류 체막을 형성하는 동시에, 어느 한쪽의 원통 베어링 면에, 회전에 의해서 윤활류체를 한 방향으로 압송하는 작용을 가진 얕은 홈을 형성하고, 또한 어느 한쪽의 원통 베어링 면의 끝부분 또는 끝부분 근처에 둘레방향 홈을 형성하고, 이 둘레방향 홈에 유체 저항을 개재해서 고압류체를 공급하는 수단을 형성한 것을 특징으로 하는 베어링장치.
  2. 제 1 항에 있어서 고압류체 공급수단이, 축의 상대회전에 따른 얕은 홈의 작용에 의해서 고압 상태로 된 유체를 둘레방향 홈에 공급하는 고압공급 통로를 이루어진 것을 특징으로 하는 베어링장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
