Abstract
In a medium-chain conveyor with two-part scrapers, in particular in the form of a double medium-chain conveyor, with a specific link thickness standardized, for example according to DIN, the horizontal links have a shorter pitch than the standard pitch. The side links of the chain wheel have a length corresponding to the length of the shortened horizontal links, which is shorter than the standard pitch; and that, in the area underneath the chain wheel side links, the teeth of the chain wheel are asymmetrical in the direction of rotation of the chain wheel or in the direction of travel of the chain, as a result of removing material on the toothed flank in the direction of travel and adding material to the opposing toothed flank. A substantially higher service life of the chain wheels and of those parts of the entire chain belt system in such conveyors interacting therewith is achieved by this.
