Description

두개의 축방향으로 격리된 수력학적 베어링 사이에 활동 저장소를 갖은 베어링 시스템
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 베어링 시스템의 실시예에서 실축척이 아닌 개략적 종단면도.
제2도는 제1도와 유사하며 단지 한 몸체가 제거된 단면도.
제3도의 III-III 선을 취한 단면도.
제4도는 제1도에서 도시한 실시예가 사용되는 전기 모터의 단면도.

Claims (3)

  1. 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.
  2. 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.
  3. 제1항 또는 제2항에 있어서, 베어링 시스템의 전기 기계의 베어링 부시와 이 베어링 부시에 결합하는 기계축을 포함하는 것을 특징으로 하는 베어링 시스템이 제공된 전기기계.
