MESH DAMPER KOCHETOV Russian patent published in 2016 - IPC F16F3/10 F16F7/08 

FIELD: machine building.

SUBSTANCE: flexible element comprises a casing made in the form of top and bottom pressure washers with collars and threaded holes. Pressure washers are made with screw thread that includes a cylindrical coil spring turns pressed with flat washers. Meshed damper is arranged inside the spring made up of cylindrical sleeve from voluminous mesh interweaving and arranged inside damping device. Damper device consists of case made of rigid flexible damping material, for example, "Agat" type. In the central part of the case along its inner diameter is a section-shaped damping ring made from elastomer, such as cast polyurethane. 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 discs there is an additional damping element.

EFFECT: improved efficiency in resonant mode of vibration isolation.
