FIELD: machine building.
SUBSTANCE: proposed attachment comprises the sleeve fitted in through aligned bores of connected flanges and jointed over inner conical surface with conical stud fitted therein with nuts screwed on its threaded ends. Said sleeve is axially locked. Sleeve inner surface has fixing section longer than that of the sleeve outer surface. Sleeve has lengthwise cut-outs starting from sleeve end on cone smaller diameter side to terminate at sleeve inner surface nonworking section on cone larger diameter side.
EFFECT: higher reliability of flange joint and load-bearing capacity, better reparability, manufacturability and lower costs of assembly/disassembly.
