본 발명은 굴삭기와 같은 궤도 차량의 트랙롤러 등에 사용된느 플로팅 씰 어셈블리에 관한 것이다. 본 발명의 어셈블리는, 다이아몬드형 단면을 가지고, 고무재로 성형되는 고정 패킹링(60) 및 회전 패킹링(80)과; 상기 패킹링의 내측면에 각각 설치되고, 금속재로 만들어지는 고정 씰링(44) 및 회전 씰링(54)을 포함한다. 고정 패킹링 및 회전 패킹링은, 고정하우징 및 회전하우징 그리고 고정 씰링 및 회전 씰링 사이에 각각 설치된다. 그리고 고정 패킹링 및 회전 패킹링은, 고정하우징 및 회전하우징 그리고 고정 씰링 및 회전 씰링과 각각 면접촉함과 동시에, 고정 패킹링 및 회전 패킹링은, 내측면에서 더 근접한 상태로 설치되어 상기 고정 씰링과 회전 씰링을 서로 밀착시키는 방향으로 탄성력을 제공하여 오일의 누유를 방지한다.

    The present invention relates to a floating seal assembly, which is used for a track roller for tracked vehicles, such as excavators. The assembly of the present invention includes a fixing packing ring (60) and a rotating packing ring (80), which have a diamond-shaped cross section and are made of a rubber material; and a fixing sealing (44) and a rotating sealing (54), which are installed on each inner side of the packing ring and are made of a metal material. The fixing packing ring and the rotating packing ring are respectively installed between a fixing housing and a rotating housing and between a fixing sealing and a rotating sealing. The fixing packing ring and the rotating packing ring are in contact with surfaces of the fixing housing, the rotating housing, the fixing sealing, and the rotating sealing. Also, the fixing packing ring and the rotating packing ring are installed closer to each other in the inner surface, so the fixing packing ring and the rotating packing ring provide electricity in order to allow the fixing sealing and the rotating sealing to be in close contact with each other, thereby preventing oil leaks.
