Claims (3)

1. Spatial disk-shaped vibration isolator with a pendulum suspension, containing a frame based on at least three elastic-damping elements of the disk-type, characterized in that the frame consists of an upper platform for placing a vibration-proof object, which is based on elastic-damping elements of the disk type by means of elastic elements, located axisymmetrically to the elastic elements, made in the form of a package of series-connected disk-shaped elastic elements mounted on the upper annular disk of the box-shaped housing of elastic-damping elements, while the lower annular disk of the housing of elastic-damping elements is installed on the common base of the spatial disk vibration isolator, and the upper annular disk of the housing of elastic-damping elements is connected to the lower annular disk mounted on the common base of the spatial plate vibration isolator by means of the ring of the housing of the elastic damping elements, while inside the rings and the housing of the elastically damping elements has a lower platform with which the rods interact with a spherical profile made on their lower part, while the upper part of the rods is made with a threaded thread interacting with a threaded bushing having a spherical profile resting on the upper plate connected through an elastic damping a bushing with a package of series-connected disk-shaped elastic elements resting on the upper annular disk of the box-shaped body of elastic-damping elements of the disk type. 2. Spatial disk-shaped vibration isolator with a pendulum suspension according to claim 1, characterized in that each of the elastic elements mounted on the upper annular disk of the box-shaped body of the vibration isolator is made in the form of a cylindrical spring, consisting of two parts with oppositely directed ends, one part of which has coils of rectangular section, and the other part of the spring is made hollow, while the opposite end of the first part is placed in the cavity of the second, the gaps of the segment profile of the contacting parts of the spring are filled with anti-friction lubricant, while a sealing collar is installed at the end of the second part of the spring to prevent lubricant leakage, and the first part of the helical spring, made with coils of rectangular cross-section with rounded edges, is covered by a tube of damping material, such as polyurethane, the gaps in the first part of the helical spring, made with coils of rectangular cross-section, which is covered by a tube of damping material, filled The gaps in the first part of the helical spring, made with coils of rectangular cross section, which is covered by a tube of damping material, are filled with crumb of friction material, made from a composition comprising the following components, at their ratio, in wt.%: a mixture of resole and novolac phenol-formaldehyde resins in a ratio of 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 friction modifier containing carbon black in the form of a mixture with kaolin and silicon dioxide 7÷15 barite concentrate 20÷35 talc 1.5÷3.0
