Claims (5)

1. A mesh vibration isolator containing a base and elastic elements, the base is made in the form of a vertical cylinder with fasteners located perpendicular to the axis of the cylinder, in its middle part, one of the fasteners being a bolt with a washer, and the other opposite located and connected to the bolt - a threaded sleeve with a washer, which is a supporting element when the vibration-insulated object is inclined, while in the upper part of the cylinder there is an elastic element made of elastomer, such as rubber or polyurethane tan, and at the bottom there is a combined elastic element, characterized in that the combined elastic element consists of three intermediate vibration-damping layers: the first layer is of dispersed elastic-damping material, in which crumbs can be used, for example, of the following materials: rubber, cork, foam, nylon, foamed polymer, as well as crumbs of solid vibration damping materials, such as agate, anti-vibrate, shvim plastic with a size of fractions of crumbs of 1.5 ÷ 2.5 mm, the second layer is knitted elastic filament, the mesh size of the elastic knitted synthetic yarn, for 10 ÷ 15% smaller size fractions crumb vibration-damping material; and the third layer is made of a continuous damping material, in which sponge rubber, needle-punched material of the type “Vibrosil” based on silica or alumino-borosilicate fiber, as well as non-woven vibration-damping material can be used. 2. A mesh vibration isolator according to claim 1, characterized in that the inner surfaces of the vertical cylinder are coated with friction material. 3. The mesh vibration isolator according to claim 1, characterized in that a glass made of friction material is fixed in a disk with a central recess, coaxially and axisymmetrically to it, while the bottom of the glass is in contact with a vibration-damping element. 4. The vibration isolator mesh according to claim 1, characterized in that as the friction material of the cup attached to the disk, friction material is used made of 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%
