Power transmission chain having links with lateral spacing elements

摘要

A power transmission chain having a plurality of inside links and guide links. Each inside link has at least one inverted tooth adapted to contact the teeth of an associated sprocket. Each link has a pair of apertures which are connected by connecting pins inserted through the apertures. The chain is provided with projections acting to maintain a spaced relationship between the guide links and the inside links. The spacing of the guide link away from the inside links is accomplished by spacing elements which may include projections formed on the guide link or an outer face of the outermost inside link, or by washers or spacers interposed therebetween.
