    • PROBLEM TO BE SOLVED: To provide an antifriction chain to perform smooth bending slide for a long period without the occurrence of abnormal wear elongation even when the chain is used together with lubrication oil extremely deteriorated and high in the degree of oxidation.
      SOLUTION: In the chain formed such that two ends of a bush 12 are securely fitted in bush holes 11a of a pair of inner bush plates 11, respectively, two ends of a coupling pin 15 are rotationally inserted in a fitted-in state in the bush 12 are securely fitted in pin holes 14a of a pair of outer plates 14 situated on both outer sides of a pair of the inner plates 11, the bush 12 is formed of a base material constituted such that thermoset treatment is applied on one kind selected from austenite stainless steel, martensite stainless steel, persipitation hardening stainless steel, high-carbon chrome bearing steel, and alloy tool steel.

    • A roller chain including a series of inner links each formed by a plurality of parallel inner link plates connected by a pair of hollow bushes. The inner links are connected by a series of outer links. Each outer link comprises a pair of parallel outer link plates connected adjacent the opposite ends thereof by a pair of pins. The pins on a given outer link extend through the bushes on the adjacent ends of two inner links to pivotally connect same together. The inner link plates and the associated bushes forming the inner links are fused together by a fillerless weld formed by electron beam or laser welding. The pins and the outer link plates can be similarly welded together. The resulting chain has substantially increased tensile and fatigue strength.
    • 一种滚子链,其包括一系列内连杆,每个内连杆由多个由一对空心衬套连接的平行内连杆构成。 内部链接通过一系列外部链接连接。 每个外连杆包括一对平行的外连杆板,它通过一对销与其相对的两端连接。 给定外链路上的销钉延伸穿过两个内连接件的相邻端部上的衬套,以将它们枢转连接在一起。 通过电子束或激光焊接形成的无填充焊缝将形成内部链节的内部连接板和相关联的衬套熔合在一起。 销和外链板可以类似地焊接在一起。 所得到的链条具有显着提高的拉伸和疲劳强度。
