FIELD: machine building.
SUBSTANCE: invention relates to machine building. Vibration isolator contains a base, elastic mesh elements, upper and lower press washers. Base is located in middle part of vibration isolator and is designed as a plate with fastening holes. Mesh elastic elements are rigidly connected to a foundation by means of backup rings. In upper mesh resilient element dry friction damper is axisymmetrically located in center. Damper is designed as the upper press washer, rigidly joint with centered ring enclosed by the axially located ring, rigidly connected with the base. Between the lower pressure washer and lower mesh resilient element vibration damping material is arranged made of three intermediate layers. Coaxial to the lower mesh elastic element an additional elastic element in the form of a spring is located.
EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
