The endless link chain of the chain drive is arranged in a chain duct (2) in which the chain joints (4) are guided. In operation, the chain is not tensioned because the length of the chain duct (2) is equal to the nominal length of the chain. As a result, the chain also has the same length at all times irrespective of the unavoidable play in the chain joints, although the chain is stretched in the section in which it runs towards the chain drive and compressed in the section following the drive. In the alternately loaded chain joints (4), the lubricant flows repeatedly between the load-bearing surfaces which have just been relieved. This chain drive can be used with advantage as a newspaper transporter in a newspaper printing machine. <IMAGE> |
