FIELD: mechanical engineering.
SUBSTANCE: invention is designed for connecting solids of revolution with provision of guaranteed compression force along axis. Device for connecting solids of revolution by means of threaded joint with opposite hand of helix has connecting threaded sleeve and sealing member. Device is provided with two members with ring support surfaces, rigidly secured on each of solids of revolution to be connected, and interconnected by elements preventing angular turning and providing longitudinal displacement. At least one detachable stop is installed on sleeve to engage with fixing member through threaded tie-rod. Thread of opposite helix is cut directly solids of revolution to be connected. Detachable stop can be made in form of split ring provided with catches.
EFFECT: provision of higher tightening torques, strength of butt joint, possibility of assembling and disassembling of butt joints in the field, simplified design.
