Power transmission chain

摘要

A chain constituted by an endlessly connected link plate groups each consisting of a plural number of link plates with paired pin-receiving holes and successively connected with adjacent link plate groups with the respective link plates intermeshed with the link plates of adjacent groups and with a shift of one pitch from the latter, by means of paired rocker pins inserted in the pin-receiving holes of the intermeshed link plates in back-to-back relation with each other, the rocker pins being formed in an arcuate shape and spaced from each other by a predetermined gap space when the centers of the pin-receiving holes of the intermeshed link plates are brought into alignment with each other. The chain may be assembled in such a manner as to maintain the gap space when the chain is lapped around a rotational drive member and a driven member, or in such a manner that the pin-receiving holes of the preceding and succeeding link plate groups are offset in the direction of the pitch line when the chain is fitted in position.
