Abstract: 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.

Abstract: The present invention relates to a tooth plate for an inverted tooth chain with two hinge openings spaced apart in the longitudinal direction and a tooth plate contour with two teeth arranged on one side in the longitudinal direction, the teeth each being limited by an outer flank and an inner flank. Here, at least one section of the tooth plate contour is shaved, where the ends of the shaved section comprise an overcut. This overcut is arranged in a low-stress area of the tooth plate contour. The invention further relates to a corresponding method for the manufacture of such a tooth plate with the pre-punching and shaving of a section of the tooth plate contour, wherein the overcut at least one end is arranged in a low-stress area of the tooth plate contour. In the subsequent normal punching of the non-shaved areas, the normally punched area of the tooth plate contour and the at least one shaved section meet in the area of the overcut at an angle to each other.
