| 摘要 |
The invention relates to a round steel chain, comprising chain links articulated to one another, wherein the individual chain links each have opposite chain bends (2), which are connected to one another by means of chain legs (3). At least every second chain link is designed as a flat link (1), wherein the chain legs (3) of the flat link (1) are flattened at the edges in the cross-section of the chain legs and have a leg width greater than the diameter of the chain bends, such that the areas of the chain legs (3) protruding beyond the diameter to the leg width form lateral bulges (4), which extend up to the chain bends (2) or into the chain bends (2). The chain bends (2) have thickened sections (5) arranged on the longitudinal outer surfaces (A) of the chain bends. |
