FIELD: machine building.
SUBSTANCE: invention relates to the machine building. Vibration isolator comprises frame made in the form of two supporting horizontal plates, resting against the installed on the common base resilient damping elements. Horizontal plates are rigidly connected to the vertical plates, which in the frame lower part are connected together by the base plate. Platform for the vibration-insulated object is installed onto the base plate through the vibration damping gasket and vertical post. Left elastic-damping element comprises body from fixing the helical cylindrical spring two oppositely arranged bushings. Dry friction element in the form of three elastic lobes forcefully covers the cylindrical spring outer surface. Right elastic-damping element comprises base, cover and elastic element. Resilient member consists of two elastomeric disk rings, which inner surface interacts with the central bushing, and the outer surface is with the cover and wall surfaces.
EFFECT: enabling increase in the vibration isolation efficiency at resonance.
