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

FIELD: machine building.

SUBSTANCE: damper includes housing made in the form of upper and lower thrust washers with beads and threaded holes. Pressure washers are made with screw thread that includes a cylindrical coil spring turns pressed with flat washers. Inside the spring a damper is located, made in the form of a sleeve. Along the sleeve inner diameter, a shaped damping ring is secured, which is made hollow, for example from the polyurethane or rubber-cord shell, which cavity is filled with a friction element. Ring is shaped in the form of two opposite surfaces of the truncated cone converging in the central part of the ring with their bases of smaller diameter. Over the surfaces of larger bases of conical surfaces of the ring discs are located. Discs are fixed by means of rods in threaded holes of pressure washers. Between the disks there is an additional damping element.

EFFECT: improved efficiency in resonant mode of vibration isolation.
