MESH DAMPER Russian patent published in 2018 - IPC F16F3/10 F16F7/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. 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 mesh dampener is arranged made in the form of cylindrical bushing from the volumetric net weave and a damper device placed inside it. Damper device consists of case made of rigid flexible damping material, for example, of "Agat" type. In the sleeve central part, a shaped damping ring is fixed along its inner diameter, made of elastomer, for example, 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 disks there is an additional damping element. Between the thrust washers and the additional damping element, additional resilient elements are installed.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
