FIELD: machine building.
SUBSTANCE: invention relates to machine building. Package of ring springs consists of external and internal annular elastic conical disks. On each of disks two spherical segments are made. Discs are located between the base and cover. Base in made as cylindrical sleeve, one of the internal discs rests against it. Cover is made in form of T-shaped section bushing with through hole. Another internal disc rests against the horizontal flange of the cover. Internal discs are installed on the cover and base via the vibration dampening rings. External and internal discs are made as truncated cone surfaces, and contain three radial slots. Slots are directed from lesser base to larger base. Each of the radial slots is ended by hole for stress relieving. Based on baffle there is additional damping element in form of truncated cone. Net damper is fixed on the cover through a vibration damping element consisting of three intermediate vibration damping layers.
EFFECT: enabling increase in the vibration isolation efficiency in resonance mode.
