ARTICULATED CHAIN WITH EXPANSION-TYPE OUTER LINK PLATE

摘要

An articulated chain includes alternate outer chain links and inner chain links interconnected by respective chain joints. The outer chain links comprise two outer link plates that are spaced apart in parallel, the outer link plates having two pin holes, which are spaced apart in the link-plate longitudinal direction and which each have fixedly arranged therein a respective joint pin of the chain joints. The inner chain links comprise two inner link plates that are spaced apart in parallel, and the joint pin being pivotably arranged in a joint opening of the inner chain links. The outer link plates comprise at least one expansion opening between the pin holes in order to reduce the bending of the joint pin and the surface pressure in the joint opening of the inner chain links, so as to improve the sliding behavior and the wear properties of the chain joints.
