Tooth-shaped chain with double rows of sealing rings

A double-row seal ring tooth-shaped chain relates to the technical field of chain transmission and comprises a double-row tooth-shaped chain structure formed by connecting an outer chain link, an inner chain link and a middle chain link, and seal rings are arranged between the outer chain link and the inner chain link and between the inner chain link and the middle chain link. The utility model discloses a double-row sealing ring tooth-shaped chain which has the advantages of being free of maintenance, good in abrasion resistance and low in meshing noise of a sealing ring chain through a double-row sealing ring tooth-shaped chain structure. Meanwhile, the transmission capacity and the operation stability of the whole chain are improved through the double-row chain structure, and the application field of the tooth-shaped chain system is remarkably widened. 一种双排密封圈齿形链，涉及链传动技术领域，包括由外链节、内链节、中链节连接而成的双排齿形链结构，所述的外链节和内链节之间、内链节与中链节之间设有密封圈。本新型公开了一种双排密封圈齿形链，通过双排密封圈齿形链结构，兼顾了密封圈链条免维护、耐磨性能好，齿形链啮合噪音低的优势。同时，双排链条结构提高了整链的传动能力与
