FIELD: machine building.SUBSTANCE: invention relates to machine building. Vibration isolator comprises base, supporting platform and resilient element located between them made in form of cylindrical equifrequential spring. Lower spring flange is fixed at the resilient base, and the upper one - on the supporting plate. Object with variable process mass whose vibration shall be isolated is fixed at the supporting platform by fastening elements. Platform is connected to the supporting unit by nuts embracing adjusting bolts. Supporting unit is fixed on the supporting plate of the vibration isolator by adjusting bolts rigidly coupled to the bushes. Every supporting unit comprises vibration damping bushes set coaxially to the adjusting bolts. Resilient base is coupled with the lower platform of the vibration isolator by three poles with screws and elastic bushes coaxially set outside the poles. Cylindrical-conical damper is located under lower spring flange resilient base. Damper is made in form of series-connected conical and cylindrical helical springs, which turns are coated with elastomer layer, for example polyurethane. Resilient base consists of alternating layers of elastic and vibration damping materials.EFFECT: higher efficiency of vibration isolation.1 cl, 2 dwg |
