FIELD: mechanical engineering; connection of thin-walled parts, rod-type parts operating under action of dynamic alternating loads. SUBSTANCE: flangeless joint has male and female parts one of which is provided with support for other part and with connecting member. Innovation consists in the following facts: connecting member is made in form of pins received by holes located across parts; pins are provided with retainers; outer surface of male part and inner surface of female part are taper in their shape wholly or partially; taper angle is equal to or less than 30 deg; pins and their holes are taper in shape with vertices of cones directed inside parts; diaphragms are located inside parts. Parts are machined over outer and inner surfaces after which one part is inserted in other up to the stop; then they are tightened up and holes are made in them to receive pins; when joint is assembled, it is rigidly secured to rods or pipes; prior to disassembly, guide member is fitted and marks are applied. EFFECT: enhanced reliability. 7 cl, 10 dwg |
