Abstract

A plate-link chain having a plurality of link plates hingedly connected with each other by pairs of rocker members that each include two rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain and are situated with play in openings in the link plates. The rocker members and the link plate openings each have respective curved contact surfaces along which the rocker members and the link plates bear against each other to transmit force. The rocker members include curved rolling surfaces along which the rocker members roll against each other during chain operation to transmit force. The play value between the rocker members and the opening in an adjacent link plate is less than 0.2 mm to minimize lateral vibrations of the chain during operation, to prevent contact of the chain with an enclosing housing and thereby reduce emitted noise.
