| 摘要 |
The invention relates to a round link chain for scraper chain conveyors in which the free space for passage of the vertical chain links (21) of the tension chain (2) in the lower run (3) of the conveyor pans (4) of the conveyor (1) is bounded between the floor (5) and the intermediate floor (6) or at the C-shaped projecting side walls at the height "x". In order to be able to use stronger tension chains for greater conveyor lengths as well, which chains do not conventionally fit into the space available in the conveyor pans (4), the legs (21a) of at least the vertical chain links (21) have a flattened cross-section transversely to the chain link plane (21c), while preserving the standard cross-sectional sizes and cross-sectional thicknesses of the vertical chain links (21) transversely to the chain link plane (21c), so that the strength characteristics of such chains are not impaired in relation to chains in accordance with DIN 22252. Flattened areas (21g) may also be present on the insides of the legs and if necessary on both longitudinal sides (21d, 21e) parallel to the chain link plane (21c). <IMAGE>
