FIELD: machine building.
SUBSTANCE: invention relates to machine building. Vibration isolator comprises a body, a base, an elastic member, a lower and upper stop limiters of the elastic member made of an elastomer, and a threaded bushing connecting the resilient member to a vibration-insulated object. Said housing is rigidly coupled with the base made in the form of round thrust block. Lower cylindrical elastic-damping element made of elastomer with the axial cylinder-conical hole serves as the lower stop limiter of the spring. Cover is rigidly connected to the axially symmetric spring by means of a threaded bushing. In threaded bushing screw for connection of resilient element with vibration isolated object is fixed. Case top part is connected with cover. Elastic limiter of the dynamic movement of the object is fixed on the end surface of the cover. Cover comprises an axially perpendicular hole for a viscous lubricant injection, e.g. solid oil, into the system. Elastomer damper is located inside the spring coaxially with it.
EFFECT: enabling increase in the vibration isolation efficiency.
