mechanical engineering. SUBSTANCE: seal-lock has bushing with recess which contains circular groove. The latter accommodates stopping member made as spring ring. Seal-lock also has rod provided with larger-diameter head positioned in the recess of bushing and provided with the first and second circular grooves. In this case, the second circular groove is positioned between the first circular groove and bottom of recess. It has transition section from groove diameter to rod diameter from side of the first groove. Pin is inserted in bushing wall. In final assembly position the pin is located in the second circular groove of rod provided with recess for pin passing from the second circular groove to rod end. Flange for individual factory marking is provided on bushing from side of recess input hole. External diameter of bushing between flange and circular groove is reduced. EFFECT: increased immunity to breaking. 2 cl, 3 dwg |
