Claims (3)
- 서로에 대해 상대적으로 회전축에 대해 회전하도록 지지되며 사이에 윤활유가 존재하는 협동하는 베어링 표면을 포함하는 두 몸체에 의해 두개의 축방향으로 간격진 수력학적 베어링을 포함하며 상기 각 베어링의 베어링면의 적어도 하나에는 나선홈의 내외부 패턴이 형성되어 있고 상기 홈의 두 패턴은 베어링 시스템이 계획하는 방향으로 베어링 시스템 회전중에 베어링면 사이의 윤활유에 압력을 형성하도록 양쪽방향으로 작용하며 상기 수력학적 베어링 사이에 위치되어 윤활유 추가량을 위한 저장소로서의 역할을 하고 상기 몸체의 두 원통형 벽부분에 의해 둘러싸인 실을 또 포함하는 베어링 시스템에 있어서, 실을 둘러싸는 두 벽부분은 시스템이 계획하는 방향으로 베어링 시스템이 회전하는 동안 실내의 윤활유에 압력이 발생하도록 서로 치우친것을 특징으로 하는 베어링 시스템.
- 제1항에 있어서, 몸체의 하나에는 회전중 압력이 형성되지 않는 원통형 벽부분 사이의 보다 큰 반경방향 간극을 갖는 구역의 실까지 연장된 구멍이 형성된 것을 특징으로 하는 베어링 시스템.
- 제1항 또는 제2항에 있어서, 베어링 시스템의 전기 기계의 베어링 부시와 이 베어링 부시에 결합하는 기계축을 포함하는 것을 특징으로 하는 베어링 시스템이 제공된 전기기계.※참고사항 : 최초출원 내용에의하여 공개하는 것임.
