Abstract
The link chain is formed of elongated links (2) connected transversely by connecting joints (4) which are formed by pairs of connecting joint elements (1). The connecting joint elements, in cross section, are somewhat crescent-shaped or bent, oval, and define joint engagement surfaces in the region of the terminal ends, for engagement with link engagement surfaces formed in apertures (5) of the link elements (2). The convex side of an inner link element (1) of the pair fits against the concave side of an outer link element of the pair, which, in turn, bears with its joint engagement against the link engagement surface of the aperture. The arrangement permits constructing all the link elements in identical manner, and, further, by placing the joint element pairs in respective link elements with the outermost ones of the link elements engaging, selectively, the link engagement surfaces either with the respective joint engagement surface on the concave side or on the convex side, permits placement of the roll-off of the link elements with respect to each other at different locations with respect to a median or center line, thereby substantially reducing noise level of the chain in operation by preventing sequential repetitive impact engagement of the link elements with a cone disk or cone pulley of the transmission.
