METHOD OF CONNECTION OF TWO OPPOSITE ENDS OF MEMBERS, DETACHABLE LINK WHOSE ENDS ARE CONNECTED BY SUCH METHOD AND METHOD OF MANUFACTURE OF DETACHABLE LINK

摘要

FIELD: mechanical engineering; connection of chains. SUBSTANCE: method consists in forming the projections on outer surfaces of ends of members or on inner surfaces of connecting half-couplings; they are mounted on ends of members, stamped on smooth surfaces of ends of members or on inner surfaces of half-couplings of projections; half-coupling are connected by means of fastenings, thus forming the detachable link; at least two opposite ends of members of this link are connected by means of two half-couplings. Method of manufacture of detachable link consists in connecting the ends of members of link by means of half-coupling; on some of their surfaces, projections are formed. Then fastenings are inserted in holes of half-couplings and half-couplings are fitted on ends of members of link, after which projections are formed on smooth surfaces and half-couplings are connected by means of connecting rod. halves of links may be connected by means of envelope provided with projections formed according to the above-mentioned method. EFFECT: enhanced strength; reduced cost. 10 cl, 12 dwg
