DYNAMIC DAMPER OF VIBRATIONS Russian patent published in 2013 - IPC E04B1/98 

FIELD: construction.

SUBSTANCE: dynamic damper of vibrations comprises balances connected to each other by links, hingedly connected to a secured object, each of which has a mass attached to the object with a suspension. At least one mass is located above points of fixation of its suspensions to the object, and others - below points of fixation of their suspensions. At least one mass is connected with a secured object by means of a damping device. The damping device is arranged in the form of at least two flat elastic rings arranged axisymmetrically and in parallel planes, outer and inner ones, which are rigidly connected to each other by means of at least two symmetrical elastic diametrically arranged elements with a through central slot, symmetrically arranged inside the element. Elements connecting outer and inner rings have lines of bending and may be fixed on rings by means of welding, for instance, of contact type, or by fastening threaded elements, or as a glue joint. Cavities formed by outer and inner elastic rings arranged axisymmetrically and in parallel planes are filled with an elastic damping meshy element arranged as reinforced from a meshy frame, filled with an elastomer, for instance, with polyurethane.

EFFECT: invention makes it possible to increase damping ability of a vibration damper.
