ЗАКЛЕПКА С ОДНОСТОРОННИМ ДОСТУПОМ

摘要

FIELD: mechanical engineering; rivets accessible at one side. ^ SUBSTANCE: proposed rivet has head and shank with wedge-shaped cut made along it over helical line. Rivet is also provided with spiral of optional profile made from intelligent material; spiral has initial helical shape. Spiral is received by wedge-shaped cut of shank. Shank is made from plastic material possessing lesser stiffness as compared with that of material of helical spiral; this material is just alloy of phase transformation into rectilinear shape at design temperature. ^ EFFECT: enhanced reliability of joint under complicated conditions. ^ 2 dwg
