DAMPER WITH ADDITIONAL ELASTIC ELEMENTS Russian patent published in 2018 - IPC F16F3/10 F16F7/08 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building, instrument making, and can be used for the process equipment, machines, and instruments vibration isolation. Damper with additional elastic elements contains body made in the form of upper and lower pressure washers with collars and threaded holes, between which a cylindrical helical spring is fixed. Pressure washers are made with the helical thread, which includes pressed by the flat washers through the screws spring turns, and inside the spring, uniaxially and coaxially to it, a damper is placed. Damper is made in the form of sleeve, by which inner diameter the shaped damping ring is fixed, made of elastomer, for example, cast polyurethane. Ring is shaped as the truncated cone two opposite surfaces, converging in the ring central part by their smaller diameter bases. Above the ring conical surfaces large bases surfaces disks are located, fixed by means of rods in the upper and lower thrust washers threaded holes, respectively. Between the damper device disks, fixed by means of rods in the upper and lower thrust washers threaded holes, respectively, inside the shaped damping ring, the additional damping element is arranged. Located between the of the damper device discs, additional damping element, fixed by means of rods in the upper and lower thrust washers threaded holes, respectively, is made by the form of surface, equidistant to the shaped damping ring surface located in the sleeve central part along its internal diameter, and in the contacting equidistant surfaces friction lubricant is placed.

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