Chain belt where load block has grooves for engagement with protrusions on link plates

摘要

A power transmission chain belt wherein each of two mutually offset parallel chains includes connected sets of parallel links, and spaced-apart parallel load block members engage the inner side of the parallel chains. Each set of parallel links includes link plates each having a pair of gripping protrusions formed so as to extend from an inner-side end face facing the load block members. The protrusions engage a pair of engaging grooves formed on each load block member, to thereby hold the link plates. The grooves are open on the opposite end faces of the load block member, and are provided with stopper means for inhibiting relative movements of the link plates and the load block member.
