COMBINED VIBRATION ISOLATION SYSTEM OF TORSION TYPE Russian patent published in 2018 - IPC F16F15/04 F16F1/14 

FIELD: machine building.

SUBSTANCE: invention refers to machine building. Vibration isolation system contains the base, the spatial transmission mechanism, the pivotally connecting base and the vibration-insulated object. Transmission mechanism is made in the form of two torsions in parallel mounted on the vibration-insulated object in hinges with oppositely attached levers at their ends. Free ends of the levers are connected with vertical rods by means of spherical hinges. Rods are connected to the base by spherical hinges. Three shock-absorbing springs are installed and fixed between the base of the vibration-insulated object and the base of the protected inter-floor overlapping of the building. Each of the three vibration damping springs contains the lower and upper support plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. Lower support plate is the base, on which the bottom flanges of the springs are rigidly secured. Between the upper support plate and the top flange of the internal spring a dry friction damper is installed.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
