FIELD: mechanical engineering; turbines.
SUBSTANCE: proposed device includes flanges of turbine cylinder housing attachment supports, bracing studs, cap nut and inner nut. Diameter of thread of inner nut relates to diameter of bracing stud as 2 to 1. Inner nut is installed with clearance relative to upper surface of joint and is provided with inner and outer threads made with equal pitch. Device is provided also with lock pins, holes for pins and slot for heating device to provide thermal interference fit. Clearance between inner nut and upper surface of threaded joint is not less than 1 mm, and number of lock pins must be not be less than 2.
EFFECT: provision of reliable operation of high stews joint under considerable vibratory and dynamic loads, including short-time dynamic actions.
