KOCHETOV'S SPRING VIBRATION ISOLATOR Russian patent published in 2015 - IPC F16F3/04 F16F7/04 

FIELD: machine building.

SUBSTANCE: vibration isolator contains bottom and top support plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. The bottom support plate is base on which the bottom flanges of springs are rigidly secured. Between the top support plate on which the vibration-isolating object is installed, and top flange of the internal spring a dry friction damper is installed. The damper consists of two contacting cylindrical discs. The bottom disc is rigidly linked with top flange of the internal spring. The top disc is rigidly linked with the top support plate. On the looking each other surfaces of discs the concentric diametric grooves and inserted in them shoulders are made.

EFFECT: increased efficiency of vibration isolation in resonance mode.
