Abstract

The invention relates to mechanical engineering, namely, to means of vibration isolation of machines and equipment with a variable position of the center of mass. The aim of the invention is to increase the efficiency of vibration isolation, achieved by reducing the connectivity of linear and angular oscillations. When the center of mass of the object is displaced, the tang 5 closes one of the electrical contacts 6, including a reversible electric motor 7, which rotates the screw 8, as a result of which the mass 4, made in the form of a nut, interacting with the screw 8, moves in the direction opposite to the center of mass . The mass can be made in the form of a pneumatic cylinder piston moved by changing the pressure in the latter. 2 Il.

The invention relates to mechanical engineering, namely to the means of vibration isolation of machines and equipment with a variable position of the center of mass.

The aim of the invention is to improve: the efficiency of vibration isolation, achieved by reducing the connectivity of linear and angular distributions.

FIG. 1 shows the proposed vibration-isolating device with a mass in the form of a nut; in fig. 2 - the same, with a mass in the form of a pneumatic cylinder norshn.

The anti-vibration device contains 11.1 form 1, a suspension system including blocks 2 and cables 3, mass 4 in the form of a nut, its movement mechanism, carried out in a vnde installed on a platform with a pin with o, contact contacts 6, revision 1- about -.rv 7 and svnorgs with him screw S, interacting with a mass of 4 (fi1. 1).

And the mass of 4 is made in the form of a piston, installed () in one year in him (Fig. 2 |.

The barrel 7 turning the screw 8, while the mass 4 moves in the direction opposite to the displacement of the center of mass of the object.

In the device shown in FIG. 2, when the center of mass of the object on platform 1 is displaced, the nozzle 11 gives a signal to the automatic pressure regulator 10, which changes the pressure in the pneumatic cylinder 12, which leads to a movement of mass 4 in the direction opposite to the mixing of the center of mass of the object.

Automatic control of the position of the center of mass of the device reduces the connectivity of the linear and angular movements of the platform.
