4열 테이퍼형 롤러 베어링
4열 테이퍼형 롤러 베어링
저속에서 중속으로 전 세계 압연기의 베어링 구성에 사용됩니다.
4열 테이퍼형 롤러 베어링은 특별히 설계된 앵귤러 콘택트 베어링입니다. 다열 롤러 배열로 높은 반경 방향 하중과 일부 축 방향 하중을 동시에 견딜 수 있습니다. 베어링의 내경은 설치 및 분해가 용이하도록 롤 넥이 느슨하게 설계되었지만 미끄러짐을 방지하기 위해 나선형 오일 홈이 필요합니다. 주로 4고 열간 압연기, 냉간 압연기의 작업 롤 및 빌렛 밀에 사용되며 컴팩트한 디자인으로 추가 스러스트 베어링을 대체할 수 있습니다.
4열 테이퍼 롤러 베어링은 테이퍼 롤러의 다열 엇갈림 배열을 사용하여 롤러 열 수를 늘려 하중 지지력을 크게 높입니다. 내부 링은 빠른 설치 및 분해를 위해 롤 넥과 느슨하게 맞물려 있지만, 윤활을 개선하고 간극으로 인한 슬립 크리프를 방지하기 위해 내경에 나선형 오일 홈이 가공되어 있는 경우가 많습니다.
기능적 특성:
이 베어링은 압연 중에 발생하는 반경 방향 힘과 일부 축 방향 힘을 동시에 견딜 수 있어 추가적인 스러스트 베어링이 필요하지 않으며 압연기 구조를 더욱 콤팩트하게 만들 수 있습니다.
적용 시나리오: 주로 반경 방향 및 축 방향 하중을 견디기 위해 압연기 베어링 구성에 사용되어 추가적인 스러스트 베어링이 필요하지 않으며 주 기계 구조를 더욱 컴팩트하게 만듭니다:
1. 4 높이 열연 및 냉연 압연기용 워크롤 지지대
2. 스틸 빔 압연기 및 빌렛 공장을 위한 롤 구성
3. 저속 및 중속 압연기용 베어링 시스템
비교 우위: 유사한 6열 원통형 롤러 베어링과 비교,
4열 테이퍼 롤러 베어링은 마찰 계수가 낮고 축 방향 하중 용량이 높습니다,
하지만 방사형 부하 용량은 약간 낮습니다.
