DOUBLE VIBRATION ISOLATION SYSTEM Russian patent published in 2017 - IPC F16F15/08 F16F3/10 

FIELD: machine building.

SUBSTANCE: vibration isolation system comprises a base, a supporting platform and two spring vibration isolators set in-between and fitted by equifrequent springs. The lower spring flange is fixed at the resilient base, and the upper one - on the supporting plate. An object with variable process mass whose vibration shall be isolated is fixed at the supporting platform by fastening elements. The platform is connected to the supporting units with the help of vertical and horizontal levers. The supporting units are fixed on the supporting plate of every vibration isolator by adjusting bolts rigidly coupled to the bushes, by nuts embracing adjusting bolts. The 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. A cylindrical-conical damper is set under the resilient base of the lower spring flange. The damper is made in the form of series-connected conical and cylindrical helical springs, the turns of which are covered with a layer of elastomer, for example polyurethane. The resilient base consists of alternating layers of resilient and vibration damping materials. Inside the equifrequent springs there are resilient-damping devices made of elastomer.

EFFECT: increased effectiveness of vibration isolation.
