FIELD: machine building.
SUBSTANCE: vibration isolator is made in the form of connected in series and identical upper and lower frames. Cylindrical helical spring is coaxially placed in each frame, the coils of which are covered with polyurethane. Frames are made in the form of eccentrically placed rigid spherical shells. Upper ends of the springs are fixed to the inner surface of the spherical shells by means of sectors. Sectors are made of a material with adhesive and vibration damping properties, for example made of polyurethane. Peripheral parts of the spherical shells are connected by two inclined resilient elements made of polyurethane. Lower spherical shell is connected to a base by means of vertical resilient elements made in the form of cylindrical helical springs.
EFFECT: increase in the vibration isolation effectiveness.
