VIBRATION ISOLATOR WITH HIGH DAMPING EFFECT Russian patent published in 2018 - IPC F16F3/10 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Vibration isolator contains a frame in the form of hard disks, rigidly connected by means of jib with a cylinder connected to the bottom. Elastic elements are installed under the discs on a common base. Left elastic element is made in the form of a spring vibration isolator with a damper, and the right one is in the form of a helical coil spring, the turns of which are covered with a vibration damping material. Upper part of the right elastic element rests against the vibration damping gasket in the hard disk of the frame, and the lower part – through the vibration damping gasket in the base. In the cylinder, a sleeve is placed coaxially, the upper end of which is rigidly connected to the platform. Bottom of the platform rests on a spring, the base of which is fixed in the bottom of the cylinder. In the gap between the cylinder and the sleeve are installed centering rings fixed on the inner surface of the cylinder.

EFFECT: enabling increase in the vibration isolation efficiency in resonance mode.
