CONNECTING DEVICE

mechanical engineering. SUBSTANCE: connecting device has embracing and embraced cylindrical parts. Surfaces of parts facing each other are provided with circular grooves. Device also has stop split flexible ring and auxiliary split ring made of material with memory-of-form effect. Parts in said device may thrust into one another. Stop splits flexible ring is mounted with initial radial pressure on embraced part circular groove surface facing it. Auxiliary split ring made of material with memory-of-form effect is introduced for stop ring movement along longitudinal axis of parts in case of its form variation. Device may have the second auxiliary split ring made of material with memory-of-form effect to ensure displacement of stop split flexible ring before the first auxiliary split ring returns to its initial form. As a result, parts may be coupled and separated without access to joint and without application of axial forces, axial shift of coupled parts is eliminated, and parts may be separated without turning of one of parts about its axis. EFFECT: enhanced efficiency. 2 cl, 7 dwg
