COMBINED VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F3/10 F16F7/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates mechanical engineering. Vibration isolator consists of an array of elastomer in the form of a toroid. Array is cured on to fastening plate. Inside the array there are two sealed cavities. In one cavity there is an elastic element, consists of 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. Bottom support plate is base on which the bottom flanges of springs are rigidly secured. Between the top support plate and top flange of the internal spring the dry friction damper is installed. Damper consists of two contacting cylindrical discs. Bottom disc is rigidly linked with top flange of the internal spring. Top disc is rigidly linked with the top support disk. On facing each other surfaces of discs the concentric diametric grooves and inserted in them shoulders are made.

EFFECT: consistency of stiffness and damping characteristics of the vibration isolator for different exposure frequencies, as well as an increase in the efficiency of vibration isolation in the resonance mode are being achieved.
