DOUBLE VIBRATION ISOLATION SYSTEM Russian patent published in 2018 - IPC F16F15/08 F16F3/10 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Vibration isolation system comprises base, supporting platform and two spring vibration isolators with equifrequential springs located between them. Lower spring flange is fixed at the resilient base, and the upper one is on the supporting plate. Vibration isolated object with variable process mass is fixed at the supporting plate by fastening elements. Platform is connected to support assemblies using the vertical and horizontal levers. Support assemblies are fixed on the every vibration isolator supporting plate using adjusting bolts rigidly coupled to bushings enclosing the adjusting bolts with nuts. Resilient base is connected to the vibration isolator lower platform by three posts with screws and with coaxially located outside the posts elastic bushings. Cylindrical-conical damper is located under the lower spring flange resilient base. Damper is made in form of in-series connected conical and cylindrical helical springs, which turns are coated with the polyurethane layer. Resilient base consists of the elastic and vibration damping materials alternating layers. Inside the equal-frequency springs made of elastomer elastic-damping devices are arranged. Under the support platform the arch type rubber vibration isolator is fixed.

EFFECT: enabling increase in the vibration isolation effectiveness.
