Abstract

축에 대한 축방향 및 회전운동을 위하여 하중을 지지하는 베어링은 축과 맞물림하기 위하여 원주방향으로 이격된 복수 아치형 베어링 패드를 지지하는 원통형 내부벽을 가진 외부셀을 포함하는 것으로서 개시되어 있다.
각각의 베어링 패드는 축상의 정적 예하중을 발휘하도록 축에 억지끼워맞춤을 하기 위하여 배열되고 탄성적으로 변형가능한 복수의 측면 팁부분, 및 축과 헐거움 끼워맞춤을 하기 위하여 배열된 측면의 팁부분의 중간의 중간부분을 포함하고 있다. 복수의 윤활 채널은 분리 베어링 패드 사이의 갭을 통하여 축과 연통하고 있다.

Description

제로 간극 베어링
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따라 형성된 베어링의 사시도, 제2도는 베어링에 의해 축의 수용전에 베어링과 축 사이의 상대 끼워맞춤을 예시하기 위하여 가상선으로 축을 도시한 끝면도, 제3도는 축의 삽입에 따라 그 편향을 예시하기 위하여 실선과 이점쇄선으로 베어링 패드의 일부를 도시한 본 발명에 따라 형성된 베어링의 확대 부분 끝면도.
