RU2293228C2 - Plate-type vibration insulator - Google Patents

Abstract

FIELD: mechanical engineering.

SUBSTANCE: vibration insulator comprises base that receives the plate for mounting the object to be insulated. The plate is connected with the lid that abuts against the stack of flexible members by means of pivoting pendulum mechanism. The stack is composed of the blocks of plate flexible members that are interconnected in series. The block of plate flexible members is made of two axially aligned plate springs, bottom and top, whose inner and outer diameters are interconnected via axially aligned T-shaped members. The flexible conical surface of the tube flexible members is provided two through grooves to define two truncated conical surfaces interconnected through two ribs directed along the generatrices of the conical surface. .

EFFECT: improved vibration insulation.

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 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 a base, in which a plate for installing a vibration-insulated object is placed, connected by means of a pendulum mechanism of a hinged type with a lid resting on a package of elastic elements consisting of series-connected blocks of disk-shaped elastic elements, a block of disk-shaped elastic elements made in the form of two coaxially arranged cup springs, the upper and lower, connected by an inner and outer diameter using coaxially arranged C is a T-shaped profile, and the elastic elements are dish-shaped, containing a dish-shaped elastic surface in the form of a truncated cone, on the elastic conical surface made in a plane parallel to the bases of the truncated cone, two through grooves with the formation of two truncated conical surfaces connected by two edges directed along the lines forming the conical surface, or on the elastic conical surface, in the plane parallel to the bases of the truncated cone, at least three through grooves with the formation of two truncated conical surfaces connected by at least three edges directed along the lines forming the conical surface.

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 base 1, in which there is a plate 7 for installing a vibration-isolating object (not shown in the drawing), connected by a pendulum mechanism 5 of the hinge type with a cover 6 resting against a package of elastic elements consisting of series-connected blocks of disk-shaped elastic elements 4. The block of dish-shaped elastic elements is made in the form of two coaxially arranged dish-shaped springs 4, upper and lower, connected by an inner and outer diameter using coaxially spaced C 3 T-shaped profile (figure 1), and the inner surface of the inner rings 3 interacts with the sleeve 2, rigidly fixed in the base 1.

The plate-shaped elastic element contains a plate-shaped elastic surface in the form of a truncated cone 8. On it is made in the plane parallel to the bases of the truncated cone, two through grooves 9 and 10 (FIGS. 2 and 3) 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 plate 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. With vibrations of the vibration-insulated object 3, installed by means of the support sleeve 1, which enters the hole 14, its spatial vibration protection and shock protection are provided.
