Claims (5)

1. A plate-shaped elastic element containing a frame, in which a plate-type elastic element is installed, the frame is made of lower and upper parts, while the lower part of the frame consists of a base made in the form of a disk with an annular internal groove in which the lower elastic ring of elastic a plate-type element, and the upper part of the frame is made in the form of a cover, which is a disk with a central annular recess, and rigidly connected by, for example, screws with an upper elastic ring of an elastic element of the arm type, moreover, in the central annular recess of the lid there is a layer of vibration-damping material, for example of polyurethane, on which a mounting plate is fixed for attaching a vibration-insulated object, the elastic element of the plate type contains at least two flat elastic coaxially arranged rings, the upper and lower connected between each other by means of at least three elastic flat plates arranged obliquely with respect to the axis of the rings, the upper ring being connected to the cap and the lower part to the lower a ring of friction material is attached to the ring to create dry friction, providing the necessary damping in the system, and flat elastic plates are located between the recesses, characterized in that as the friction material of the ring attached to the lower part of the lower ring of the elastic element to create dry friction, material made from a composition comprising the following components in their ratio, wt. %: mixture of resol and novolac phenol formaldehyde pitches in the ratio 1: (0.2-1.0) 28 ÷ 34 fibrous mineral filler containing glass roving or a mixture of glass roving and basalt fiber in a ratio of 1: (0.1-1.0) 12 ÷ 19 graphite 7 ÷ 18 carbon black friction modifier in the form of a mixture with kaolin and silicon dioxide 7 ÷ 15 barite concentrate 20 ÷ 35 talc 1.5 ÷ 3.0 2. The plate-shaped elastic element according to claim 1, characterized in that in the lower part of the frame to the base, made in the form of a disk with an annular internal groove, a lower mounting plate is additionally attached, designed to be installed on the floor with vibroactive equipment and made in the form of a multilayer a vibrodamping circular disk, consisting of at least three layers: the central layer is made of a rigid vibrodamping material, for example, of the “Agate” type, and symmetrically arranged relative to the upper and lower layers are made of a mesh frame, filled with an elastomer, for example polyurethane. 3. The disk-shaped elastic element according to claim 1, characterized in that the lower mounting plate is combined and consisting of three layers: the central layer is made of hard vibration-damping material, for example, such as “Anti-vibration”, and the upper and lower layers symmetrically located relative to it are made from knitted elastic synthetic threads embedded in an elastomer, for example polyurethane. 4. The plate-shaped elastic element according to claim 1, characterized in that as the friction material of the ring attached to the lower part of the lower ring of the elastic element to create dry friction, a sintered friction material based on copper is used, containing zinc, iron, lead, graphite, vermiculite, copper, chromium, antimony and silicon, in the following ratio of components, wt. %: zinc 6.0 ÷ 8.0; iron 0.1 ÷ 0.2; lead 2.0 ÷ 4.0; graphite 3.0 ÷ 7.0; vermiculite 8.0 ÷ 12.0; chrome 4.0 ÷ 6.0; antimony 0.05 ÷ 0.1; silicon 2.0 ÷ 3.0; copper is the rest.
