本考案は、例えば建造物の床用ダンパや橋梁用ダンパ又は精密計測器や工作機 械用のダンパ、或いはその他諸種の振動発生機器類の台座等に広く利用すること ができる防振装置に関するものである。 The present invention relates to an anti-vibration device that can be widely used, for example, as a floor damper for a building, a damper for bridges, a precision measuring instrument, a damper for machine tools, or a pedestal for other types of vibration generators. Is.
【０００２】[0002]
従来、この種の防振装置には振動を伝える側とその振動を受ける側との間にゴ ム等の弾性物質から成る緩衝体を介在させ、その緩衝体によって振動を吸収させ るようにしたものが広く用いられている。 Conventionally, in this type of vibration isolator, a cushioning body made of an elastic material such as rubber is interposed between the side transmitting the vibration and the side receiving the vibration, and the cushioning absorbs the vibration. Things are widely used.
【０００３】[0003]
しかし、従来の弾性物質を用いた防振装置においては、一般に振動を充分に吸 収できないため、振動を効率良く遮断できないという問題を有している。また、 繰り返して加えられる強い振動に対して構造的に充分な強度が得難いため、耐久 性等にも問題がある。 However, in the conventional vibration isolator using the elastic material, there is a problem that the vibration cannot be efficiently blocked because the vibration is generally not sufficiently absorbed. Moreover, it is difficult to obtain a structurally sufficient strength against a strong vibration repeatedly applied, so that there is a problem in durability and the like.
【０００４】 本考案の目的は、比較的簡単で丈夫な構造によって、振動を効率良く遮断でき るようにした防振装置を提供することにある。An object of the present invention is to provide an anti-vibration device capable of efficiently isolating vibration with a relatively simple and durable structure.
【０００５】[0005]
上述の目的を達成するための本考案に係る防振装置は、基台上に弾性体から成 る筒形の中空弾性台座を配置し、その底面を前記基台に接着し、該中空弾性台座 の上面に制振金属板を接着し、該制振金属板の中心部に荷重を掛けるようにした ことを特徴とするものである。 A vibration-damping device according to the present invention for achieving the above-mentioned object comprises a cylindrical hollow elastic pedestal made of an elastic body on a base, and the bottom surface of the hollow elastic pedestal is adhered to the base to form a hollow elastic pedestal. A damping metal plate is adhered to the upper surface of the, and a load is applied to the central portion of the damping metal plate.
【０００６】[0006]
上述の構成を有する防振装置は、制振金属板の中心部に加えられる振動はその 制振金属板と中空弾性台座との相乗作用によって効率良く吸収され、基台には殆 ど伝達しない。逆に、基台に加えられる振動も中空弾性台座と制振金属板との相 乗作用によって吸収され、制振金属板の中心部に取り付けた荷重には殆ど伝わる ことはない。 In the vibration damping device having the above-mentioned structure, the vibration applied to the central portion of the vibration damping metal plate is efficiently absorbed by the synergistic action of the vibration damping metal plate and the hollow elastic pedestal, and is hardly transmitted to the base. Conversely, the vibration applied to the base is also absorbed by the product of the hollow elastic pedestal and the damping metal plate, and is hardly transmitted to the load attached to the center of the damping metal plate.
【０００７】[0007]
本考案を図示の実施例に基づいて詳細に説明する。 図１は本考案に係る防振装置の実施例の断面図、図２は平面図を示し、基台１ と一体になった円筒状の取付容器２の内部には、例えば天然ゴム又はネオプレン のような合成ゴム等から成る円筒状の中空弾性台座３が配置され、その底面は粘 弾性を有する接着剤４によって基台１に固定されている。中空弾性台座３の上面 には、例えば十字形又は円板状等の適当な形状を持った制振金属板５が接着剤６ によって固定されている。制振金属板５としては、例えば鋼板又はその他の金属 板に非鉄金属や合成樹脂等を接着し振動を効率良く吸収するものが用いられてい る。 The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a cross-sectional view of an embodiment of a vibration isolator according to the present invention, and FIG. 2 is a plan view thereof. Inside a cylindrical mounting container 2 integrated with a base 1, for example, natural rubber or neoprene is used. A cylindrical hollow elastic pedestal 3 made of such synthetic rubber is arranged, and its bottom surface is fixed to the base 1 by an adhesive 4 having viscoelasticity. On the upper surface of the hollow elastic pedestal 3, a damping metal plate 5 having an appropriate shape such as a cross shape or a disk shape is fixed by an adhesive 6. As the damping metal plate 5, for example, a non-ferrous metal or a synthetic resin is adhered to a steel plate or another metal plate to efficiently absorb vibration.
【０００８】 なお、中空弾性台座３及び制振金属板５の外周面と取付容器２の内周面との間 は、互いに接触しないように僅かな空隙ｇが設けられ、中空弾性台座３は制振金 属板５と共に自由に弾性変形できるように、また過度の変形が取付容器２によっ て防止されるようになっている。A slight gap g is provided between the outer peripheral surfaces of the hollow elastic pedestal 3 and the vibration damping metal plate 5 and the inner peripheral surface of the mounting container 2 so that the hollow elastic pedestal 3 is controlled. It is designed so that it can be freely elastically deformed together with the vibrating plate 5, and excessive deformation is prevented by the mounting container 2.
【０００９】 制振金属板５の上面の中心部には、支持すべき物体、例えば建造物や精密測定 機械等のような振動を嫌う物体、或いは逆にモータや洗濯機等のように振動を発 生する物体の荷重を受ける荷重受体７が接着剤８によって固定されている。また 、荷重受体７の上に支持すべき物体を取り付けるために、荷重受体７にはボルト 孔９が設けられているが、他の取付手段により物体を荷重受体７自体に取り付け てもよい。なお、接着剤６、８も前述の接着剤４と同様に粘弾性の接着剤が用い られている。At the center of the upper surface of the vibration damping metal plate 5, an object to be supported, for example, an object that does not like vibration such as a building or a precision measuring machine, or conversely, a vibration such as a motor or a washing machine is used. A load receiver 7 that receives the load of a generated object is fixed by an adhesive 8. Further, the load receiving body 7 is provided with a bolt hole 9 in order to mount the object to be supported on the load receiving body 7, but even if the object is attached to the load receiving body 7 itself by other mounting means. Good. As the adhesives 6 and 8, viscoelastic adhesives are used similarly to the adhesive 4 described above.
【００１０】 本考案に係る防振装置においては、荷重受体７の上にモータや洗濯機のような 振動を発生する物体を取り付けた場合に、その振動は荷重受体７から制振金属板 ５及び中空弾性台座３を経過して基台１に伝達されるが、その途中において制振 金属板５に加えられる垂直方向及び水平方向の振動は、制振金属板５及び中空弾 性台座３の垂直方向及び水平方向の弾性変形によって殆ど吸収され、またその間 に介在される粘弾性の接着剤８、６、４等によっても吸収されるため、基台１に は殆ど振動が伝わらなくなる。In the vibration isolator according to the present invention, when an object that generates vibration such as a motor or a washing machine is mounted on the load receiver 7, the vibration is transmitted from the load receiver 7 to the damping metal plate. 5 and the hollow elastic pedestal 3 are transmitted to the base 1, but the vertical and horizontal vibrations applied to the vibration-damping metal plate 5 in the middle thereof are suppressed by the vibration-damping metal plate 5 and the hollow elastic pedestal 3. Most of the vibrations are absorbed by the elastic deformation in the vertical and horizontal directions, and also by the viscoelastic adhesives 8, 6, 4 and the like interposed therebetween, so that the vibration is hardly transmitted to the base 1.
【００１１】 逆に、荷重受体７の上に建造物や精密測定器械のような振動を嫌う物体を取り 付けた場合に、地震等の外力によって基台１に加えられる振動は、中空弾性台座 ３及び制振金属板５の弾性変形及び粘弾性の接着剤４、６、８の振動吸収作用に よって吸収されるため、荷重受体７には殆ど振動が伝達しなくなる。On the contrary, when an object such as a building or a precision measuring instrument that is not sensitive to vibration is mounted on the load receiver 7, the vibration applied to the base 1 by an external force such as an earthquake is generated by the hollow elastic pedestal. 3 and the vibration-damping metal plate 5 are absorbed by the elastic deformation of the viscoelastic adhesives 4, 6 and 8, and the vibration is hardly transmitted to the load receiver 7.
【００１２】[0012]
以上説明したように本考案に係る防振装置は、筒形の中空弾性台座とその上に 接着した制振金属板との相乗作用により、基台に加えられる振動又は制振金属板 の中心に加えられる振動を殆ど吸収することができ、振動を効果的に遮断するこ とが可能である。 As described above, the vibration damping device according to the present invention is designed so that the vibration applied to the base or the center of the vibration-damping metal plate is caused by the synergistic action of the cylindrical hollow elastic pedestal and the vibration-damping metal plate adhered thereon. Most of the applied vibration can be absorbed, and the vibration can be effectively blocked.
