ABSTRACT:
A chain 32 and sprocket 10 combination which reduces chordal action and wear allowing for higher output and greater durability of the devices that use chains and sprockets. The chain 32 has hinged joints equipped with a torsional spring 42 that resist hinging and thus reduces chordal action. The sprocket 10 has cam manipulated teeth 12 that prevent both sprocket tooth and chain wear.
