Abstract

PURPOSE:To obtain a vibration-proof device which has an effect on damping vibration even if horizontal displacement and vibration occur by arranging one or plural ring-shaped elastic materials of round or cylindrical form in cross- section and fixing it or them with two mounting plates at different places. CONSTITUTION:A vibration-proof device is constituted by fitting a plurality of round or cylindrical vibration-proof rings 1 made of such elastic materials as rubber, spring steel, synthetic resin and the like to mounting plates 2 having circular cutouts 6 by means of keep plates 3. Then, since said device is made to be rotatable at the circular cutout 6 of the mounting plate 2 of the vibration- proof ring, it irrationally follows up if horizontal displacement occurs, and as for vertical vibration, it is absorbed by the vibration-absorption function of the ring-shaped elastic material. Accordingly, by constituting a vibration-proof device with a circular vibration-proof ring 1, a vibra-tion-proof device which can be used without any problem in relation to horizontal displacement and vibration and has an effect on damaging vibration may be obtained.

Description

[Detailed description of the invention] [Industrial use 1! F) The present invention relates to a vibration isolating device that is provided to prevent or attenuate the vibration of the equipment from being transmitted to the installation surface when the equipment is installed.

[Conventional technology]

Currently, there are various types of vibration isolators, such as those made of rubber and springs, depending on the type, purpose, and use of the machine. The most commonly used anti-vibration rubber is shown in Figure 8. In the figure, reference numeral 12 is rubber with a vibration-proofing effect, which is glued to the seat plate 13, and is attached to the mounting plate 1 of the equipment by means of mounting bolts 14.
5 and stand] 6 are fixed respectively. An example of the use of the vibration isolator is shown in Fig. 7.

In the figure, reference numeral 9 denotes a vibration isolator through which a device 8 that generates vibrations is fixed to the platform 7.

In such a device, when the device 8 vibrates vertically as shown by the arrow 10, the vibration isolating device 9, that is, the vibration isolating rubber 12 causes @!
1′! Attenuates lJ.

[Problem that the invention seeks to solve]

Since the conventional anti-vibration rubber is constructed as shown in Figure 8,
If a horizontal displacement occurs in the direction of the arrow 11 shown in FIG. 7, the vibration-proof rubbers 12 and 13 are bonded together, so there is a drawback that the vibration-proof rubbers 12 and 13 will break due to the horizontal displacement exceeding the adhesive strength. Further, although it has a damping effect and is strong against vibrations in the vertical direction, there is a problem that it is weak against vibrations in the horizontal direction due to the adhesive strength.

This invention was made to solve the above-mentioned problems, and it is an object of the present invention to provide a vibration isolating device that has a vibration damping effect even if displacement occurs in the horizontal direction.

[Means for solving problems]

The vibration isolator according to the present invention includes one or more ring-shaped elastic members having a circular or cylindrical cross section.

Multiple pieces are lined up and fixed to two different locations such as the top and bottom, left and right of the ring using mounting plates, and the mounting plate and rings are processed, bent, etc. so that the circular or cylindrical ring can easily rotate. A notch is provided in the mounting plate and attached to the holding plate.

[Effect]

The vibration isolator in this invention has a vibration isolator with a cylindrical cross section or
This uses a circular ring of elastic material to rotate at the mounting plate of the vibration isolator, so if there is a horizontal displacement, it will easily follow it, and it will also move vertically. Vibrations are absorbed by the vibration-absorbing action of the ring-shaped elastic material.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 to 4, C11 is a circular or cylindrical anti-vibration ring made of an elastic material such as spring steel or synthetic resin, and has a circular notch 6. A plurality of vibration isolators are attached to a mounting plate 2 by presser plates 3.

When the vibration isolator with such a structure is installed as shown in FIG.
Of course, the vibrations are absorbed by the ring, but even if a horizontal displacement as shown by arrow 11 occurs, the ring mounting plate is circular as shown by diagonal lines in Fig. 6, so it rotates and the ring It follows the displacement without twisting. On top of that,
Vertical vibrations are damped by the vibration isolation ring. This vibration isolator is in its normal position in the cooled state, but it can also be expected to be effective when the operating temperature becomes high or low and the position is displaced because it cannot absorb the expansion and contraction caused by the temperature difference.

In the above embodiment, the anti-vibration ring was installed by providing a semicircular notch in the mounting plate and presser plate, but the same effect can be achieved by attaching it with a presser foot 19 as shown in Fig. 5. The effects can be expected. Also, the number of anti-vibration rings is not necessarily multiple, and the same effect can be obtained even with just one anti-vibration ring.
As long as it has a circular or cylindrical cross section and can be processed into a ring shape and has elasticity, anything can be used, such as rubber, so-called synthetic resin, etc. by selecting the size and number appropriately according to the purpose. [Effect of the invention] As described above, according to the present invention, since the vibration isolating device is configured with a circular vibration isolating ring, an anti-vibration device that can be used without problems against horizontal displacement and vibration and has a vibration gJ damping effect can be obtained. It's effective.
