ANTI-VIBRATION SYSTEM FOR MACHINE-TOOLS Russian patent published in 2013 - IPC F16F15/04 F16F3/10 

FIELD: machine building.

SUBSTANCE: anti-vibration system contains four vibration dampers with different stiffness and connected to supporting members of equipment. Vibration-isolating machine-tool is mounted on platform which rests on two vertically arranged vibration dampers. One vibration damper is installed over a free end of the platform and with another end it is attached to a lever. The lever has L-shaped section in vertical plane and "П"-shaped section in horizontal plane. Two vibration dampers are fastened to the lever on opposite sides relative to the free end of the platform. Each vibration damper is designed in the form of two flat elastic rings arranged axisymmetricly and in parallel planes. Rings are rigidly interconnected by means of two symmetric diametrically arranged elements with through central slot. Elements connecting inner and outer rings have curvature lines and may be attached to rings by welding, for example contact welding, or by fastening threaded elements or as bonding connection. Cavities formed by inner and outer rings are filled with elastically damping screen element made from screen carcass covered with elastomer, for example polyutherane.

EFFECT: increasing efficiency of anti-vibration in resonance mode and simplification of design and assembly.
