Description

本発明は、粘性・流体ダンパ装置に関し、詳しくは、精密製造機器や測定機及び製品検査機器等、外乱振動を排除したい機器を柔らかい弾性体にて振動絶縁する際の減衰要素として好適な粘性・流体ダンパ装置に関するものである。   The present invention relates to a viscosity / fluid damper device, and more particularly, a viscosity / fluid damper device suitable as a damping element when vibration-insulating a device desired to eliminate disturbance vibration, such as precision manufacturing equipment, measuring equipment, and product inspection equipment, with a soft elastic body. The present invention relates to a fluid damper device.

従来から柔軟な弾性体を用いる弾性支持装置の減衰要素としてオイルダンパや粘性ダンパが使用されている。
従来のオイルダンパや粘性ダンパは、減衰方向以外の方向への自由度に制約があり、弾性体の横剛性不足と偏荷重による横方向スライドに対応するために別途弾性体の横ズレ防止機構又は発生した横ズレをダンパ部に伝えない機構を設ける必要がある。また、従来の粘性流体にシャフトやプレートを浸すタイプの粘性ダンパでは、密封処理が不完全であり、横転させると内部の液体が流出してしまう。 Conventionally, an oil damper or a viscous damper is used as a damping element of an elastic support device using a flexible elastic body.
Conventional oil dampers and viscous dampers have restrictions on the degree of freedom in directions other than the damping direction, and in order to cope with insufficient lateral rigidity of the elastic body and lateral sliding due to uneven load, It is necessary to provide a mechanism that does not transmit the generated lateral displacement to the damper portion. Further, in a conventional viscous damper in which a shaft or a plate is immersed in a viscous fluid, the sealing process is incomplete, and the liquid inside flows out when it is rolled over.

特許文献１には、制御対象物の鉛直方向の振動を減衰させることを目的として、シリンダー内にシリコーンオイルを収容し、シリンダー内に配置した円板をロッドにて制御対象物に連結するピストンを備えた構成の精密除振台が提案されている。   Patent Document 1 discloses a piston that contains silicone oil in a cylinder and connects a disk arranged in the cylinder to the control object with a rod for the purpose of dampening vertical vibration of the control object. A precise vibration isolation table having a structure is proposed.

しかし、この特許文献１の精密除振台の場合、上述した場合と同様、減衰方向以外の方向への自由度に制約があるとともに、シリンダーの密封処理が万全でなく、横転させると内部の液体が流出してしまう惧れがある。
特開平０９−１５８９７９号公報 However, in the case of the precision vibration isolation table of Patent Document 1, as in the case described above, the degree of freedom in the direction other than the damping direction is limited, and the cylinder is not completely sealed. May leak.
JP 09-158979 A

解決しようとする問題点は、減衰方向とは異なる方向への偏荷重による変位が発生しても振動減衰性能を効果的に発揮でき、且つ、横転したような場合でも内部の粘性液体の流出防止対策が万全な粘性・流体ダンパ装置が存在しない点である。   The problem to be solved is that the vibration damping performance can be effectively exhibited even when displacement due to an eccentric load in a direction different from the damping direction occurs, and the internal viscous liquid is prevented from flowing out even if it rolls over. This means that there is no viscous / fluid damper device that can be used as a countermeasure.

本発明の粘性・流体ダンパ装置は、設置体と支持体との間に配置して前記支持体を一定量浮上させた位置を基点としてその振動減衰を行う粘性・流体ダンパ装置であって、前記設置体上に配置する粘性流体を収納したダンパ本体と、前記支持体に固定する取り付けプレートに一端を連結し他端を前記粘性流体内に臨ませたシャフトと、前記粘性流体内で前記ダンパ本体の内壁との間にクリアランスをもって、且つ、前記シャフトに対してこのシャフトと直交する方向の自由度を持って連結した前記粘性流体との間で減衰力を得る減衰プレートとを有することを最も主要な特徴とする。 The viscosity / fluid damper device of the present invention is a viscosity / fluid damper device that is arranged between an installation body and a support body and performs vibration damping based on a position where the support body is levitated by a certain amount. A damper main body storing a viscous fluid disposed on the installation body, a shaft having one end connected to a mounting plate fixed to the support body and the other end facing the viscous fluid, and the damper main body within the viscous fluid And a damping plate that obtains a damping force with the viscous fluid connected to the shaft with a clearance and with a degree of freedom in a direction perpendicular to the shaft with respect to the shaft. Features.

請求項１記載の発明によれば、減衰プレートにより本来の振動減衰効果を発揮するとともに、減衰方向とは異なる方向への偏荷重による変位が発生しても振動減衰性能を効果的に発揮でき、更にロッキング運動に対しても振動減衰効果を発揮でき、横剛性の低い弾性体で支持する弾性支持装置に取り付ける減衰要素としても使用可能な粘性・流体ダンパ装置を提供することができ、かつ、許容以上の横方向スライドが生じダンパ本体の内壁と減衰プレートの外周が接触した場合においても、減衰プレート自体の振動吸収作用によりダンパ本体の内壁への振動伝達を抑えることができ、更に、横転したような場合でも内部の粘性液体の流出防止できる粘性・流体ダンパ装置を提供することができる。 According to the first aspect of the present invention, the vibration damping performance can be effectively exhibited even when a displacement due to a biased load in a direction different from the damping direction occurs, while exhibiting the original vibration damping effect by the damping plate. Furthermore, it is possible to provide a viscous / fluid damper device that can exhibit a vibration damping effect against rocking motion and can be used as a damping element attached to an elastic support device supported by an elastic body having low lateral rigidity. Even when the above-mentioned lateral slide occurs and the inner wall of the damper main body and the outer periphery of the damping plate come into contact, vibration transmission to the inner wall of the damper main body can be suppressed by the vibration absorbing action of the damping plate itself, and it seems that the rollover has occurred. In this case, it is possible to provide a viscous / fluid damper device capable of preventing the internal viscous liquid from flowing out.

請求項２記載の発明によれば、シャフトに対して長穴嵌合によりこのシャフトと直交する方向にスライド及び回転可能に連結した減衰プレートを備える構成で請求項１記載の発明と同様な効果を発揮する粘性・流体ダンパ装置を提供することができる。 According to the second aspect of the present invention, the same effect as that of the first aspect of the present invention can be obtained by including a damping plate connected to the shaft so as to be slidable and rotatable in a direction orthogonal to the shaft by fitting with a long hole. A viscous / fluid damper device can be provided.

請求項３記載の発明によれば、シャフトに対して筒状カラーを介在させた長穴嵌合によりこのシャフトと直交する方向にスライド及び回転可能に連結した減衰プレートを備え、設置体にボルト止め固定したダンパ本体、支持体にボルト止め固定した取り付けプレートを備える構成で、請求項１記載の発明と同様な効果を発揮する粘性・流体ダンパ装置を提供することができる。 According to a third aspect of the present invention, an attenuation plate is provided that is coupled to a long hole with a cylindrical collar interposed between the shaft and a shaft that is slidable and rotatable in a direction orthogonal to the shaft, and is bolted to the installation body. A viscous / fluid damper device that exhibits the same effect as that of the first aspect of the present invention can be provided with a structure including a fixed damper main body and a mounting plate fixed to the support by bolting.

本発明は、減衰方向とは異なる方向への偏荷重による変位が発生しても振動減衰性能を効果的に発揮でき、且つ、横転したような場合でも内部の粘性液体の流出防止対策を万全とするという目的を、設置体と支持体との間に配置して前記支持体を一定量浮上させた位置を基点としてその振動減衰を行う粘性・流体ダンパ装置であって、前記設置体上に配置する粘性流体を収納したダンパ本体と、前記支持体に固定する取り付けプレートに一端を連結し他端をダンパ本体の開口側から前記粘性流体内に臨ませたシャフトと、前記粘性流体内で前記ダンパ本体の内壁との間にクリアランスをもって、且つ、前記シャフトに対してこのシャフトと直交する方向の自由度を持って連結した前記粘性流体との間で減衰力を得る減衰プレートと、前記ダンパ本体の開口側を密封状態で閉塞するカバー体とを有する構成により実現した。   The present invention can effectively exhibit vibration damping performance even when displacement due to an offset load in a direction different from the damping direction occurs, and even if it rolls over, it will take thorough measures to prevent the internal viscous liquid from flowing out. It is a viscous / fluid damper device that is arranged between an installation body and a support body and performs vibration damping based on a position where the support body is levitated by a certain amount, and is disposed on the installation body A damper body containing a viscous fluid to be stored, a shaft having one end connected to a mounting plate fixed to the support and the other end facing the viscous fluid from the opening side of the damper body, and the damper in the viscous fluid A damping plate that obtains a damping force between the viscous fluid and a clearance that is connected to the inner wall of the main body and that has a degree of freedom in a direction perpendicular to the shaft with respect to the shaft; It was realized by the configuration and a cover member for closing the opening side of the main body in a sealed state.

以下に、本発明の実施例を詳細に説明する。
図１、図２は本実施例の粘性・流体ダンパ装置１を示すものであり、この粘性・流体ダンパ装置１は、図２に拡大して示すように、例えば床等の設置体２１と減衰対象物である支持体２２との間に配置して前記支持体２２を一定量浮上させた位置を基点としてその振動減衰を行うものである。 Examples of the present invention will be described in detail below.

As shown in an enlarged view in FIG. 2, the viscous / fluid damper device 1 is damped with an installation body 21 such as a floor. The vibration damping is performed with the position where the support 22 is lifted by a certain amount as a base point between the support 22 which is an object.

本実施例の粘性・流体ダンパ装置１は、図１、図２に示すように、前記設置体２１上にボルト２３を用いてボルト止め固定するとともに粘性流体４を内部に収納した有底筒状のダンパ本体６と、前記支持体２２にボルト２３を用いてボルト止め固定する例えば円板状の取り付けプレート８に一端を連結し、他端をダンパ本体６の開口側から前記粘性流体４内に臨ませたシャフト３と、前記粘性流体４内で前記ダンパ本体６の内壁との間に図２に示すクリアランスｔをもって、且つ、前記シャフト３の他端に対して図３に示す筒状カラー７を介在させた長穴嵌合により連結した例えば円板状で弾性材からなる減衰プレート５と、前記ダンパ本体６の開口側を密封状態で閉塞する柔軟性を有する蛇腹状のカバー体２とを有している。   As shown in FIGS. 1 and 2, the viscous / fluid damper device 1 of the present embodiment is fixed to the installation body 21 with bolts 23 and fixed with bolts 23, and the viscous fluid 4 is housed inside. One end of the damper body 6 and a support plate 22 fixed with bolts 23 using bolts 23, for example, a disk-shaped mounting plate 8, and the other end into the viscous fluid 4 from the opening side of the damper body 6. A cylindrical collar 7 shown in FIG. 3 has the clearance t shown in FIG. 2 between the exposed shaft 3 and the inner wall of the damper main body 6 in the viscous fluid 4 and the other end of the shaft 3. A damping plate 5 made of, for example, a disk and made of an elastic material, which is connected by fitting a long hole with a gap interposed therebetween, and a bellows-like cover body 2 having flexibility for closing the opening side of the damper main body 6 in a sealed state. Have.

前記減衰プレート５は、拡大して示す図３及び図４に示すように、その中心部に長穴１１が形成され、筒状カラー７を嵌装した固定ネジ１２を前記減衰プレート５の下面側から長穴１１を貫通して前記シャフト３にねじ込むことで、図５に示すように、前記減衰プレート５をシャフト３の回りを回転可能に、且つ、前記減衰プレート５とシャフト３とを相対的にシャフト３と直交する方向にスライド可能に構成している。
なお、図３中、１３は固定ネジ１２と減衰プレート５の下面との間に介在させるワッシャーである。 As shown in FIGS. 3 and 4 which are enlarged, the damping plate 5 has a long hole 11 formed at the center thereof, and a fixing screw 12 fitted with a cylindrical collar 7 is provided on the lower surface side of the damping plate 5. As shown in FIG. 5, the damping plate 5 can be rotated around the shaft 3 and the damping plate 5 and the shaft 3 can be rotated relative to each other. It is configured to be slidable in a direction orthogonal to the shaft 3.
In FIG. 3, reference numeral 13 denotes a washer interposed between the fixing screw 12 and the lower surface of the attenuation plate 5.

次に、上述した構成の本実施例の粘性・流体ダンパ装置１の作用を図５、図６を参照して説明する。
本実施例の粘性・流体ダンパ装置１によれば、前記減衰プレート５と粘性流体４との作用で本来の垂直方向の振動減衰作用を発揮する。 Next, the operation of the viscous / fluid damper device 1 of the present embodiment having the above-described configuration will be described with reference to FIGS.
According to the viscous / fluid damper device 1 of the present embodiment, the vibration damping action in the original vertical direction is exhibited by the action of the damping plate 5 and the viscous fluid 4.

また、前記シャフト３が偏荷重等により初期設定のクリアランスｔの値を超えて横方向（水平方向）に大きく偏心しても、減衰プレート５が図５に示すように回転し、且つ、減衰プレート５とシャフト３とが前記長穴１１に拘束されつつ相対的にシャフト３と直交する方向にスライドすることで、水平面全方向に対してダンパ本体６の内壁と減衰プレート５との接触を受け流すことができる。   Further, even if the shaft 3 exceeds the initial clearance t due to an eccentric load or the like and greatly decenters in the lateral direction (horizontal direction), the damping plate 5 rotates as shown in FIG. And the shaft 3 slide in a direction that is relatively orthogonal to the shaft 3 while being constrained by the elongated hole 11, the contact between the inner wall of the damper main body 6 and the damping plate 5 can be received in all horizontal directions. it can.

また、偏荷重による横方向へのスライド発生を想定して前記クリアランスｔを設定し、且つ、減衰プレート５の形状や粘性流体４の粘性を調整することによって、所望の減衰力を実現することができる。   In addition, it is possible to realize a desired damping force by setting the clearance t on the assumption that a lateral slide occurs due to an uneven load and adjusting the shape of the damping plate 5 and the viscosity of the viscous fluid 4. it can.

また、本実施例の粘性・流体ダンパ装置１によれば、減衰プレート５が全方向への変位に対して自由度を有するため、粘性・流体ダンパ装置１のロッキング運動に対しても減衰性能を発揮する。   Further, according to the viscous / fluid damper device 1 of the present embodiment, the damping plate 5 has a degree of freedom with respect to displacement in all directions, so that the damping performance is also provided for the rocking motion of the viscous / fluid damper device 1. Demonstrate.

更に、減衰プレート５の材質を弾性体とすることで、許容以上の横方向スライドが生じダンパ本体６の内壁と減衰プレート５の外周が接触した場合においても、減衰プレート５自体の振動吸収作用によりダンパ本体６の内壁への振動伝達を抑えることができる。   Further, by making the material of the damping plate 5 an elastic body, even when an excessive lateral slide occurs and the inner wall of the damper body 6 and the outer periphery of the damping plate 5 come into contact with each other, the damping plate 5 itself absorbs vibration. Vibration transmission to the inner wall of the damper main body 6 can be suppressed.

また、前記柔軟性を有する蛇腹状のカバー体２により、前記ダンパ本体６の開口側を密封状態で閉塞するように構成しているので、図６に矢印で示すように、偏荷重等によりシャフト３がダンパ本体６の中心からいずれかの方向に偏心しても、前記カバー体２がダンパ本体６の開口に対する密封性を保ちつつ追従して変形するので、粘性流体の流出を確実に防止することができる。   In addition, since the flexible bellows-like cover body 2 is configured so that the opening side of the damper main body 6 is sealed in a sealed state, as shown by an arrow in FIG. Even if 3 is decentered in any direction from the center of the damper main body 6, the cover body 2 follows and deforms while maintaining the sealing performance with respect to the opening of the damper main body 6. Therefore, it is possible to reliably prevent the viscous fluid from flowing out. Can do.

更に、本実施例の粘性・流体ダンパ装置１によれば、複雑な機構等を用いることなく、単純な構造にて上述した種々の作用効果を発揮させることが可能であり、後述するような横剛性の低い空気バネのような弾性体を使用する弾性支持装置へ減衰要素として適用することが可能であるとともに、弾性支持装置内部へ簡易に取り付けることもできる。   Furthermore, according to the viscous / fluid damper device 1 of the present embodiment, the various functions and effects described above can be exhibited with a simple structure without using a complicated mechanism. It can be applied as a damping element to an elastic support device using an elastic body such as an air spring having low rigidity, and can be easily attached to the inside of the elastic support device.

図７は、本実施例の粘性・流体ダンパ装置１の弾性支持装置３０への取り付け例を示すものであり、この弾性支持装置は、横剛性の低い空気バネ３１を床等の設置体２１と減衰対象物である精密製造機器等のような支持体２２との間に配置して、前記支持体２２を一定量浮上させた状態で振動減衰を行うものである。この場合に、本実施例の粘性・流体ダンパ装置１を弾性支持装置３０に付加することによって、空気バネ３１の横剛性の低い点に対しては、粘性・流体ダンパ装置１の上述した作用により受け流すことができるという前提のもとに、緻密な機構を要せず全体として効果的な振動減衰効果を発揮させることができるシステムを容易に実現することができる。   FIG. 7 shows an example of attachment of the viscous / fluid damper device 1 of this embodiment to the elastic support device 30. This elastic support device includes an air spring 31 having low lateral rigidity and an installation body 21 such as a floor. It is arranged between a support body 22 such as a precision manufacturing device or the like that is an object to be damped, and vibration damping is performed in a state where the support body 22 is floated by a certain amount. In this case, by adding the viscous / fluid damper device 1 of the present embodiment to the elastic support device 30, the above-described action of the viscous / fluid damper device 1 is applied to the point where the lateral stiffness of the air spring 31 is low. Based on the premise that it can be passed, a system capable of exhibiting an effective vibration damping effect as a whole without requiring a precise mechanism can be easily realized.

本発明は、上述した場合の他、地震、交通振動等の影響を抑えたい建物等のような各種の構造物等にも幅広く適用可能である。 In addition to the above-described case, the present invention can be widely applied to various structures such as buildings that want to suppress the influence of earthquakes, traffic vibrations, and the like.
