Description

The invention relates to mechanical engineering, instrumentation and can be used for vibration isolation of technological equipment, machine tools, devices.

The closest technical solution to the claimed object is an elastic element according to the author's certificate of the USSR No. 763626, F 16 F 7/00, 1978 (prototype), containing elastic flat elements made in the form of a spring suspension.

A disadvantage of the known device is the complexity of the elastic element and the lack of efficiency at the resonance due to the lack of vibration damping.

The technical result is an increase in the effectiveness of vibration isolation in resonance mode and simplification of design and installation.

This is achieved by the fact that in a plate-type vibration isolator containing elastic elements made in the form of a package of serially connected disk spring blocks, the disk-shaped elastic element block is made in the form of two coaxially located disk springs, the upper and lower, connected by the coaxially inward and outer diameters located rings of the T-shaped profile, and the elastic elements are made of a plate type, containing a plate-shaped elastic surface in the form of a truncated cone; on the elastic conical surface, in the plane parallel to the bases of the truncated cone, two through grooves are formed to form two truncated conical surfaces connected by two edges directed along the lines forming the conical surface, or on the elastic conical surface is made in a plane parallel to the bases of the truncated cone, at least at least three through grooves with the formation of two truncated conical surfaces connected by at least three ribs directed along the forming conical surface lines.

In Fig.1 shows a General view of the plate type vibration isolator, Fig.2, 3 shows the elastic element of the disk type with two ribs, Fig.4, 5 - the elastic element of the disk type with three ribs.

The plate type vibration isolator contains a support sleeve 1 for installing a vibration-insulated object 3, a stop sleeve 2 for placing it on the base, and a disk-shaped elastic element unit made in the form of two coaxially located disk springs, upper 4 and lower 5, connected by an inner and outer diameter with coaxially located rings of the T-shaped profile 6 and 7 (figure 1).

The plate-shaped elastic element comprises a plate-shaped elastic surface in the form of a truncated cone 8. On it, in the plane parallel to the bases of the truncated cone, two through grooves 9 and 10 (FIGS. 2 and 3) are formed with the formation of two truncated conical surfaces 11 and 12 connected by two ribs 13 directed along the lines forming a conical surface. A hole 14 is provided for accommodating the support sleeve 1.

The elastic element of the disk type can be made up of at least three through grooves 15, 16, 17 (Figs. 4 and 5) with the formation of two truncated conical surfaces 11 and 12, connected by at least three ribs 18, 19, 20, directed along lines forming a conical surface. The holes 14 in these elastic elements serve to fix the vibration-insulated object or intermediate structures of the vibration isolator, for example, the support sleeve 1.

The plate type vibration isolator works as follows.

When the vibration insulated object 3 is installed by means of the support sleeve 1, which enters the hole 14, its spatial vibration protection and shock protection are provided.
