PLATE VIBRATION ISOLATOR BY KOCHETOV Russian patent published in 2016 - IPC F16F3/10 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Proposed resilient plate element has two flat resilient rings with central bore arranged coaxially. Said rings are secured in parallel horizontal planes and rigidly interconnected by two resilient elements. Resilient elements are arranged radially in horizontal plane and in vertical plane at the angle of 10÷80°. Resilient elements are convex or concave bent over spherical surface and made in form of cylindrical elastic vibration damping rods. Rods consist of hard elastic core arranged in cylindrical shell from polyurethane. Resilient elements are secured at said rings by threaded fasteners or glued thereto. Cavities formed by rings, are filled with elastic damping combined element made of solid damping material crumb, filled with elastomer, for example polyurethane. Between rings and elastic damping combined element additional vibration damping layers are arranged, for example, from needled fabric of "Vibrosil" type based on of silica or aluminoborosilicate fibre.

EFFECT: improved efficiency in resonant mode of vibration isolation.
