VIBRATION INSULATING SYSTEM Russian patent published in 2017 - IPC F16F7/104 F16F15/06 

FIELD: machine engineering.

SUBSTANCE: proposed vibration insulation system comprises coaxial rod supporting an elastic element and a slide moving vertically along said rod between stroke limiters, levers and springs. The levers with cantilever parts on which compensating masses are arranged are hinged to the springs. The elastic element is made in form of cylindrical helical spring and consists of two portions with mutually opposite ends. The first spring part has rectangular section turns with rounded edges, and the second part is made hollow. The opposite directed end of the first part is located in the cavity of the second part. The segmental profile gaps of the contacting spring parts are filled with antifriction lubricant. The packing seal is mounted at the end of the second spring part to prevent lubricant leakage. The first part of the spring is enclosed by the tube of a damping material. The gaps in the first part of the spring covered by the tube of damping material are filled with crumble of friction material.

EFFECT: increased efficiency of vibration isolation due to reduction of dynamic forces of inertia acting on protected object from the bearing elastic element side.
