DOUBLE PLATE VIBRATION ISOLATOR BY KOCHETOV Russian patent published in 2016 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Dish-type resilient element comprises two resilient elements arranged oppositely relative to resilient elements 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 rigid vibration damping material crumb or copper based sintered friction material.

EFFECT: improved efficiency in resonant mode of vibration isolation.
