Abstract

The present invention relates to a vibration-proof pad. More specifically, a method for manufacturing a vibration-proof pad, enabling an elastic unit to be installed inside a rubber unit, enabling the elastic unit to be connected to a vibration shaft and a fixed shaft to enable the elastic unit to prevent vibration to maintain stable vibration-proof performance even if an anti-vibration rubber is damaged.

Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing an anti-vibration pad having an elastic part,

The present invention relates to an anti-vibration pad, and more particularly, an elastic part is provided inside a rubber part, and the elastic part is connected to an excitation shaft and a fixed shaft, respectively. The present invention also provides a method of manufacturing a vibration-proof pad.

In general, rotating machines such as motors, fans, pumps, and reciprocating machines such as internal combustion engines inevitably cause vibration during operation. When vibrations generated from these machines are transmitted to the surroundings, they cause anxiety and discomfort to a person It can damage not only the life but also damage the building structure where the machine is installed, cause the malfunction of the precision equipment and control system installed nearby, and the accuracy of vibration measuring equipment, precision equipment, And may cause failure of these machines. Also, when the vibration is transmitted to the building structure, structure borne noise may be generated, which may cause noise pollution.

In order to reduce such vibration, the vibration-proof pad 1 is used as shown in Fig.

The vibration proof pad 1 includes a rubber portion R and an excitation axis GS and a fixed axis FS disposed inside the rubber portion R. [

That is, the vibration generating member provided on the exciting axis GS transmits the vibration to the fixed shaft FS during vibration, and the rubber portion R disposed therebetween attenuates the vibration. With this configuration, .

However, in the case of the conventional vibration damping pad as described above, due to hardening and irregular load of the rubber part, the rubber pad is deteriorated to cause cracking in the direction perpendicular to the load direction, and ultimately the rubber part may be damaged.

Such a phenomenon causes a phenomenon such that the vibrating body is separated from the vibration-proof pad, so that it is difficult to maintain a stable vibration-damping performance.

Meanwhile, since the anti-vibration pad itself is widely known, the anti-vibration pad itself is described in detail in the following prior art documents, so that redundant description and illustration are omitted.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

In addition, the following embodiments are not intended to limit the scope of the present invention, but merely as exemplifications of the constituent elements set forth in the claims of the present invention, and are included in technical ideas throughout the specification of the present invention, Embodiments that include components replaceable as equivalents in the elements may be included within the scope of the present invention.

FIG. 2 is a schematic view illustrating an anti-vibration pad according to an embodiment of the present invention, and FIGS. 3 and 4 are schematic views illustrating a process for fabricating an anti-vibration pad according to an embodiment of the present invention.

Example

The vibration damping pad 100 according to an embodiment of the present invention includes a rubber portion R disposed between the shaft GS and the fixed shaft FS as shown in Fig. 2, and the rubber portion R And a pair of plates 110 having a plate shape and disposed with the fixed shaft FS and the driven shaft GS, respectively.

At this time, an elastic part 120 is provided between the pair of plates 110, and both sides of the elastic part 120 are installed on the exciting axis GS and the fixed axis FS, respectively.

That is, even if the rubber portion R is broken when the vibration is inputted through the shaft GS, the elastic portion 120 absorbs the vibration, so that the dustproof performance can be maintained.

However, in the case of the present invention, the elastic part 120 plays a role as described above. As a result, the rubber part (R) Thereby solving the problem.

As shown in the figure, the fixed shaft FS is fixed to a plate 111 of the plate 110 by a fixing part FS2 provided on a side of the rubber part R inward, And a fixed shaft main body FS1 provided on the side surface.

The excitation axis GS may include a fixed portion GS2 provided on the side of the other plate 112 in the inner side of the rubber portion R and a fixed portion GS2 provided on the outer side surface of the rubber portion R And may include a shaft main body GS1.

That is, as shown in FIG. 2, the fixed shaft main body FS1 is installed on a plate 111 disposed on the left side in the drawing, and the exciter shaft main body GS1 is installed on a plate 112 disposed on the right side in the drawing do.

The fixed portion FS2 of the fixed shaft FS may be disposed on the right side of the plate 111 disposed on the left side in the figure and disposed inside the rubber portion R, (GS2) may be disposed on the left side of the plate 112 disposed on the right side in the drawing and disposed inside the rubber portion R.

Fixing holes FS3 and GS3 are formed in the fixing portions FS2 and GS2 so that both ends of the elastic portion 120 are fixed.

As shown in the figure, the fixed shaft FS and the driven shaft GS use bolts, and the fixed portions FS2 and GS2 are fixed to the fixed shaft FS and the fixed shaft FS, It is also possible to use the head of the bolt.

That is, after the heads of the bolts are disposed inside the plates 110, fixation holes FS3 and GS3 are formed in the heads of the bolts to fix both ends of the elastic part 120 respectively.

The elastic portion 120 is for reducing the vibration transmitted from the axis GS having an excitation as described above, and for this purpose, a coil spring is also usable as shown.

However, this is merely an example for explaining the present invention. It is a matter of course that the elastic body 120 can use other kinds of springs, such as a dish spring, as long as it can absorb vibration as described above.

Hereinafter, a method of manufacturing the vibration damping pad 100 of the present invention will be described with reference to FIGS. 2 to 4. FIG.

As shown in FIG. 3, the shaft GS and the fixed shaft FS are installed on the pair of plates 110, and the fixed portions GS and GS of the fixed shaft FS and the fixed shaft FS, FS2 are provided on the inner side surfaces of the pair of plates 110. [

At this time, the exciting axis GS and the fixed axis FS can use bolts as described above, and the heads of the bolts can be used as the fixing portions GS2 and FS2.

Both ends of the elastic portion 120 are fixed to the fixing holes GS3 and FS3 of the fixing portions GS2 and FS2, respectively. At this time, the fixing portions GS2 and FS2 can be formed by a tool such as a well-known drill (refer to FIG. 3).

Then, the pair of plates 110 are covered with rubber by injection to form a rubber portion R (see FIG. 2).

As shown in the figure, the rubber part R may be formed by injecting rubber between the pair of plates 110. The rubber part R may be formed by injecting rubber with the space between the plates 110 and the entire plate 110, It is also possible to wrap it.

On the other hand, the exciting axis GS, the fixed axis FS, and the elastic portion 120 are arranged to have the same center line CL.

This is because the vibration can be amplified without attenuation unless the excitation axis GS, the fixed axis FS, and the elastic portion 120 are on the same center line CL.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
