SPATIAL SPRING VIBRATION ISOLATOR BY KOCHETOV WITH BUILT-IN DAMPER Russian patent published in 2017 - IPC F16F3/10 F16F7/01 

FIELD: machine engineering.

SUBSTANCE: vibration isolator comprises a base, a vertical rod, an elastic element and a hinge for connecting the string to an elastic element or a vibration-isolating object. The hinge is an intermediate support and control cross-shaped element. Resilient 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 the 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 a crumble of friction material.

EFFECT: increasing the efficiency of vibration isolation in resonance mode and increasing the sensitivity of the vibration isolator to horizontal movements.
