敷設される防振パッドに関するものである。Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to air conditioning equipment such as air conditioners, machine tools such as presses and lathes, industrial equipment such as compressors, transformers, pumps, etc.
This relates to vibration-proofing pads that are installed on the underside of power equipment, office machines, and other machines that generate vibrations.

昭３８−５６１３号公報等によって公知となっている。(Prior art) Conventionally, anti-vibration pads are made of elastic materials such as rubber.
The elasticity of this material provides an anti-vibration effect. In order to enhance the vibration-proofing effect of this vibration-proofing pad, a pad having a large number of protrusions on the surface of the base or both the front and back surfaces is known as disclosed in Japanese Utility Model Publication No. 38-5613.

漸進的に果たされるため、防振効果が良いものとなる。Furthermore, a group of protrusions formed by combining a plurality of types of protrusions with different heights is also known, such as in Japanese Utility Model Publication No. 57-44126. If this configuration is made by combining protrusions of different heights, as the load (vibration) increases, the protrusions with higher heights will be elastically deformed in order, and the vibration absorption effect will be gradually achieved, so the vibration isolation effect will be good. Become.

中心線が一致する状態で設けている。On the other hand, in the conventional pads with the protruding material described above, in order to ensure good installation stability when two or more pads with the same structure are stacked and used, the protrusions on both the front and back sides are aligned with each other's center line. It is set in a matching state.

ると振動吸収（防振）効果がなお不十分となっていた。However, according to this configuration, vertical vibration from the machine is transmitted from the upper protrusion to the lower protrusion, both when using only one pad and when using two or more pads in a stack. Since the information is transmitted at the central portion, the elastic deformation of the protrusion occurs in one pattern in the vertical direction, and the amount of deformation (deflection) is small. Further, even with respect to vibrations in the diagonal direction and the horizontal direction, since this vibration acts on the center portion of the lower projection, the amount of deflection of the lower projection becomes small. In this respect, the vibration absorption (vibration isolation) effect of conventional pads is still insufficient.

れる場合を示している。This anti-vibration pad is cut into an appropriate size as described above (or uncut) and used by being placed on the underside of various machines that generate vibrations. FIG. 3 shows a case where one pad is laid between the bottom surface of the machine M and the floor surface F.

動吸収作用が加えられる。In this state, vibrations from the machine M are basically absorbed by the elastic deformation effect of the entire pad due to the elastic material, and to this vibration absorption effect is added by the elastic deformation (deflection) of the projections on both the front and back sides.

良いものとなる。In this case, each protrusion group c in the protrusion groups on both the front and back sides
1. Since G2 is composed of four types of protrusions 2 to 5 with different heights, no load or small load (small vibration)
In this state, the highest first protrusion 2 is on the bottom surface of the machine M or the floor surface W.
The vibration absorbing function is exerted by the deflection of this first protrusion 2. Then, as the load increases, the second
The protrusion 3, then the third protrusion 4, and then the fourth protrusion 5 sequentially come into contact with the lower surface of the machine M or the floor F, and finally the vibration absorption function is exerted by the deflection of all the protrusions 2 to 5. . That is, the projections 2 to 2 on the lower surface of the machine M or the floor surface F
5, the vibration absorbing effect is achieved gradually. Moreover, the first protrusion 2, which is the highest, is the smallest and most flexible, and the subsequent ones become less flexible in stages, and the deflection characteristics of the protrusion groups G1 and G2 correspond to the increase in load. The vibration absorption efficiency is improved.
このような突起２〜５による振動吸収機能は、第４図に
示すように二枚（または三枚以上）のパッドが上下積層
状態で使用される場合に釦、基本的に同様に果される。The vibration absorption function of the protrusions 2 to 5 is basically performed in the same way as the button when two (or three or more) pads are used in a stacked state as shown in Fig. 4. .
また、このパッドによるときは、表裏の突起グループに

。In addition, when using this pad, the positional relationship of the protrusions is set so that in the protrusion groups on the front and back sides, different types of protrusions correspond to each other with their centers shifted in the circumferential direction. Effective vibration absorption function is demonstrated both during inspection and when using pad stacking.

The vertical vibrations acting on the front protrusions 2-5 are applied to the back protrusions 2-5 through the base 1. In this case, from the first protrusion 2 on the front side to the fourth protrusion 5 on the back side, and from the second protrusion 3 on the front side to the third protrusion on the back side.
Vibration is transmitted to the protrusion 4 and from the fourth protrusion 5 on the front side to the first protrusion 2 on the back side, but at this time, this vibration
Since an unbalanced load acts on each of the back side protrusions 2 to 5 at a position shifted in the circumferential direction from the respective center, each of the back side protrusions 2 to 5 bends significantly at the portion receiving this uneven load. In other words, each of the backside protrusions 2 to 5 is not compressed and deformed as a whole so that the overall height is lowered on average, as would be the case when a load is applied to the center, but is partially crushed by an uneven load. , and other parts are deformed by the reaction, resulting in an irregular and active elastic deformation movement, which increases the amount of deflection of the entire projection, and by extension, the entire projection group.
このため、振動吸収機能が拡大される。Therefore, the vibration absorption function is expanded.
このような作用は、第４図に示すパッド積層使用状態に

する各突起２〜５がともに大きくたわみ、これによって
効果的な振動吸収機能が発揮される。This effect is similarly carried out between the facing protrusion groups of the upper and lower pads in the pad stacking state shown in FIG. 4 as well. That is, the vibrations transmitted from the back side protrusions 2 to 5 of the upper pad to the front side protrusions 2 to 5 of the lower pad act as an unbalanced load on the front side protrusions 2 to 5 at positions shifted from their centers, and the Since the force acts on the rear side protrusions 2-5 of the upper pad, each of these opposing protrusions 2-5 is deflected to a large extent, thereby exerting an effective vibration absorbing function.
さらに、斜めまたは水平振動が加えられた場合において

作用することにより、同突起５が水平方向にたわみ品い
ものとなる、といった作用が得られ、これにより振動の
吸収効果が高められる。Furthermore, even when diagonal or horizontal vibrations are applied, when the pads are stacked in use, for example, the fourth protrusion 5 on the back side of the upper pad comes into contact with the first protrusion 2 on the front side of the lower pad at a position shifted from its center. Therefore, when diagonal or horizontal vibration (load) acts eccentrically on the upper rear fourth protrusion 5, the protrusion 5 is deflected in the horizontal direction, thereby reducing the vibration. Absorption effect is enhanced.

５による不規則な面で受けられることとなる。このため
、単純な円形突起等と比較して、振動の吸収、減衰効果
が高いものとなる。In addition, when using this embodiment pad, each protrusion 2 to 5
are formed in a fan shape and are arranged at intervals on the same circumference, so the horizontal force is applied to each of these fan-shaped protrusions 2 to 2.
It will be accepted on an irregular surface due to 5. Therefore, the vibration absorption and damping effect is higher than that of a simple circular protrusion or the like.
以上のような点により、この防振パッドによるときは、
垂直、斜め、水平の各方向の振動を効率良く吸収し、高
い防振効果を得ることができる。Due to the above points, when using this anti-vibration pad,
It efficiently absorbs vibrations in vertical, diagonal, and horizontal directions, providing a high vibration-proofing effect.

安定性が良いものとなる。このため、パッド積層使用時
に、突起間の隙間を埋めるためにパッド間に鉄板等を挿
入するといった面倒がなくなる。On the other hand, when using pad stacking as shown in FIG. 4, under no load, between the opposing protrusion groups of the upper and lower pads,
Since the protrusions of different types (different heights) come into contact with each other and all the protrusion surfaces are in contact with each other, the stability of this pad stacking state is good. This eliminates the trouble of inserting a steel plate or the like between the pads to fill the gaps between the protrusions when the pads are stacked.

上記偏荷重によって活発となる。(Effects of the Invention) As described above, according to the present invention, the protrusion groups on both the front and back sides are formed by a plurality of types of protrusions having different heights and cross-sectional areas, and the relationship between the protrusion groups on both the front and back sides is such that different types of protrusions are formed. The positional relationship of the protrusions is set so that they correspond to each other with their centers shifted in the circumferential direction, and vibrations in vertical, diagonal, and horizontal directions are Because it is configured to act as an unbalanced load at a position offset from the center of the protrusion on the protrusions that face each other when used in a laminated state, compared to a conventional pad in which the centers of the protrusions on both the front and back sides coincide, Deflection becomes active due to the above unbalanced load.
これにより、突起による振動吸収機能が拡大されるため
、防振効果が高いものとなる。This expands the vibration absorption function of the protrusions, resulting in a high vibration-proofing effect.
