Claims (5)

1. The elastic element of the disk type, containing the frame, in which the elastic element of the disk type 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 is placed dish-shaped elastic 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 elastic element dish-shaped type, and in the central annular recess of the lid there is a layer of vibration-damping material, for example, polyurethane, on which a mounting plate is fixed for attaching a vibration-insulated object, the plate-type elastic element contains at least two flat coaxially located elastic rings, upper and lower, interconnected by 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 to the bottom a ring of friction material is attached to the lower ring to create dry friction, which provides 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, in 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 elastic element of a disk type 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, an additional lower mounting plate is designed to be installed on the floor with vibroactive equipment, and made in the form of a multilayer vibro-damping circular disk, consisting of at least three layers: the central layer is made of a rigid vibro-damping material, for example, “Agate” type, and symmetrically located In fact, the upper and lower layers are made of a mesh frame filled with an elastomer, for example polyurethane. 3. The elastic element of the disk type 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 made of knitted elastic synthetic threads, embedded in an elastomer, for example polyurethane. 4. The elastic element of the disk type according to claim 1, characterized in that at least a two-layer vibration damping structure is placed in the central annular recess of the lid, on which a mounting plate is fixed for attaching a vibration-insulated object, with the top layer facing the mounting plate, made of an elastomer, such as polyurethane, and the second layer facing the cover of the upper part of the frame is made of hard vibration damping material, such as type "Agate".
