The present invention relates to a track roller chain assembly for a lower drive of an amphibious excavator, wherein brackets and links are connected by a shaft so as to be rotatable with respect to each other, the shaft has a roller mounted thereto, and, from a structure in which a dust seal comprising a first seal and a second seal is closed by an in-built cover at both end surfaces of the roller, durability can be increased by mounting the dust seal to the roller, which is a lower drive component of an amphibious excavator, and adding a lubrication function.

    La présente invention concerne un ensemble chaîne à rouleaux de chenille pour un entraînement inférieur d'une excavatrice amphibie, des supports et les liaisons étant raccordés par un arbre de manière à pouvoir tourner les uns par rapport aux autres, l'arbre présentant un rouleau monté sur celui-ci, et, à partir d'une structure dans laquelle un joint d'étanchéité contre la poussière comprenant un premier joint et un second joint est fermé par un couvercle intégré au niveau des deux surfaces d'extrémité du rouleau, la durabilité peut être augmentée par le montage du joint d'étanchéité contre la poussière sur le rouleau, qui est un élément d'entraînement inférieur d'une excavatrice amphibie et par l'ajout d'une fonction de lubrification.

    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.
