摘要
The link chain according to the invention is preferably intended for scraper-chain conveyors of long conveyor lengths and correspondingly high drive powers, and comprises vertical and horizontal chain links that are hooked into one another in an articulated manner. The vertical chain links have a non-round, approximately semicircular cross-section provided on the external contour with a flattening, and the horizontal chain links have an oval internal opening whose clear internal width, has a shape corresponding to the cross-sectional contour of the vertical chain links, and is greater than the clear internal width of the vertical chain links. It is preferable that the pitch and the length of the horizontal chain links is greater than the pitch and length of the vertical chain links. The external boundary of the nose parts of the horizontal chain links preferably extend at right angles to the chain axis, with the result that a broad chainwheel bearing surface is formed. In the case of a single-strand or two-strand scraper-chain assembly, the horizontal chain links serving for the scraper connection may be designed in the manner of webbed chain links having a central web which has a push-in opening which serves for the coupling connection of the scrapers with the aid of coupling pins arranged on the latter.
