The present invention relates to a track roller chain assembly for driving the underside of an amphibious excavator. More particularly, the present invention relates to a track roller chain assembly capable of increasing durability by attaching a dust seal to a roller, which is a part for driving a lower part of an amphibious excavator, and adding a lubrication function, from a structure in which a bracket and a link are rotatably connected to each other by a shaft, the shaft is equipped with the roller, and a cover having the built-in dust seal including a first seal and a second seal is closed on both end surfaces of the roller.

    본 발명은 브래킷과 링크를 샤프트에 의하여 상호 회동 가능하게 연결하되, 샤프트에는 롤러가 장착되고, 롤러의 양단부 면에는 제1 씰과 제2 씰을 포함하는 더스트 씰이 내장된 커버에 의하여 마감되도록 한 구조로부터, 수륙양용 굴삭기의 하부 구동용 부품인 롤러에 더스트 씰을 장착하고 윤활 기능을 부가함으로써 내구성을 증대시킬 수 있도록 한 수륙양용 굴삭기의 하부 구동용 트랙 롤러 체인 어셈블리에 관한 것이다.
