In a chain wheel system tooth blocks are mounted on the circumferential periphery of the drum and are driven by a mating chain. The length of the tooth blocks equals at least the spacing between two links in the mating chain. The tooth blocks are attached to spacers fitted to the circumferential periphery of the drum. Various segment pieces or spacer members can be attached to the drum separating adjacent tooth blocks.
