Abstract

본 발명은 복수의 베어링을 연결한 후 하우징과 일체로 구비하며, 어느 일측의 베어링부가 파손되더라도 베어링의 교체나 보수 주기가 길어질 수 있는 하우징 일체형 다중 베어링 유닛에 관한 것으로, 제1베어링부와, 상기 제1베어링부와 나란하게 구비되는 제2베어링부 및 상기 제1베어링부에 접촉되며, 제1베어링부와 제2베어링부를 수용하도록 연장 형성된 하우징으로 이루어지며, 제1베어링부의 반경 방향 외측으로 구비된 외륜, 제2베어링부의 반경 방향 내측으로 구비된 내륜 및 제1베어링부의 내측과 제2베어링부의 외측을 일체로 이루는 연결륜을 포함한다. 본 발명의 하우징 일체형 다중 베어링 유닛에 따르면, 일측 베어링부의 내륜과 타측 베어링부 외륜이 일체로 회전되도록 연결하여 하우징과 일체로 형성함으로써 각각의 베어링부가 회전을 분담하게 되므로 베어링부 중 일부가 손상되더라도 손상되지 않은 다른 베어링부를 통해서 계속 회전하는 것이 가능하여 베어링의 교체나 보수 주기가 길어질 수 있으며, 하우징과 베어링부 사이의 조립공차를 고려할 필요가 없는 효과가 발휘된다.
