DOUBLE PLATE VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator comprises two resilient elements arranged oppositely relative to the separating element vertical axis. Each resilient element comprises dished resilient surface in form of truncated cone, on which, in the plane, parallel to truncated cone bases, three through grooves are made forming two truncated conical surfaces connected by three fins. In separating element central part damping cylinders are fixed coaxially to resilient elements, which are made from cast polyurethane and enter with gap to holes at truncated conical surfaces vertices. Damping cylinders are rigidly connected with separating element by means of adhesive joint. Separating element is made in form of hollow disk filled with friction material crumb.

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