FIELD: machine building.
SUBSTANCE: damper consists of top and bottom support plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. Bottom support plate is base on which the bottom flanges of springs are rigidly secured. Between the top support plate and top flange of the internal spring the dry friction damper is installed. Damper consists of two contacting cylindrical discs. Bottom disc is rigidly linked with top flange of the internal spring. Top disc is rigidly linked with the top support disk. On surfaces of discs facing each other are concentric diametric spherical surfaces: grooves and their projections. Upper disc is made from steel, and lower one-from friction material.
EFFECT: improved efficiency in resonant mode of vibration isolation.
