PLATE VIBRATION ISOLATOR Russian patent published in 2018 - 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 radially arranged in horizontal plane and in vertical plane at an angle within the 10÷80°. Resilient elements are convex or concave bent over spherical surface and made in form of flat plates made of spring steel, which surfaces are covered with polyurethane. Resilient elements are secured at said rings by threaded fasteners or glued thereto. Formed by the rings cavities are filled with an elastic-damping composite element, made of the filled with polyurethane crumbs of solid vibration damping materials. Between rings and elastic damping combined element additional vibration damping layers are arranged, for example from a needle-punched material of "Vibrosil" type based on silica or aluminoborosilicate fiber.

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