FIELD: construction; fixture. ^ SUBSTANCE: threaded fixing product contains a head, a threaded rod, a flange, teeths. Teeth are located on all basic area of a flange with a return cone and a corner to 1°30' which vertex is directed to an axis of a rod and rounded. Width of a tooth is defined from expression H=D-D1, where D - a flange outside diameter, D1 - an interior diameter of a gear surface, which is defined from condition D1 = (l.2+l.5)d, where d - diameter of a rod. ^ EFFECT: stopping effect improves, crack development and threaded coupling destruction is excluded, and there is a possibility to reuse a threaded fixing product. ^ 2 cl, 2 dwg |
