FIELD: manufacturing technology.SUBSTANCE: invention relates to a steel link chain, in particular, to design of a separate chain link. Link (2) of a chain connecting two other engaged with it links (3, 3.1) with formation of a round-steel chain in the form of a drive chain of a scraper conveyor has two bends (4, 5) and two legs (7, 7.1) connecting bends (4, 5). Link on the outer side facing the opposite side from inner space (6) of link (2) has at least one working surface (8, 11, 15, 15.1, 16). Herewith the link is made asymmetric on at least one of bends (4, 5) relative to at least one of asymmetric median planes x-y, where x is the length direction of link (2) of the chain, y is the width direction of link (2) of the chain.EFFECT: technical result is improvement of service life of the chain.14 cl, 5 dwg |
