Description

この発明は、車両等の移動体に搭載される耐震性の要求される制御機器等の機器に適用される防振装置に関する。   The present invention relates to a vibration isolator that is applied to a device such as a control device that requires earthquake resistance and is mounted on a moving body such as a vehicle.

従来、この種の防振装置は、車両等の移動体に設置して、原動機側からの振動や揺動が制御機器等の機器に伝わるのを(振動)吸収して、振動や揺動の発生を抑制し、振動が原因となる機器性能の劣化を防ぐようにしている。   Conventionally, this type of vibration isolator is installed in a moving body such as a vehicle, and absorbs vibration (vibration) transmitted from a prime mover side to a device such as a control device. It suppresses the occurrence and prevents the deterioration of equipment performance caused by vibration.

また、移動体に人が搭乗して運転する運転室がある場合には、振動や揺動を極力低減させて運転室の居住性を改善するための防振装置を設けている。この種の防振装置を備えた油圧ショベル等の移動体を例に取れば、特に運転室側においては横揺れ振動や縦揺れ振動が激しく、居住性は悪い。   In addition, when there is a driver's cab in which a person rides on a moving body, a vibration isolator is provided to improve the comfort of the driver's cab by reducing vibration and swing as much as possible. Taking a moving body such as a hydraulic excavator equipped with this type of vibration isolator as an example, particularly on the cab side, the rolling vibration and the vertical vibration are intense, and the comfortability is poor.

そこで、従来のこの種移動体では、運転室の居住性を改善するために、機械室からの振動や走行中において生じる横方向の振動(横揺れ振動)を吸収できるようにして、運転室の居住性を改善したものが知られている(特許文献1参照)。   Therefore, in order to improve the comfortability of the cab in this type of conventional mobile body, it is possible to absorb vibrations from the machine room and lateral vibrations (rolling vibrations) that occur during traveling. What improved the habitability is known (refer patent document 1).

図9は、従来の防振装置1の概要を示す要部断面図である。   FIG. 9 is a cross-sectional view of an essential part showing an outline of the conventional vibration isolator 1.

この防振装置1は、移動体本体側の台座2と、運転室側の床板3と、これらの台座2と床板3の間に設けられる防振装置本体4とから構成されている。   The vibration isolator 1 includes a pedestal 2 on the movable body main body side, a floor plate 3 on the cab side, and a vibration isolator main body 4 provided between the pedestal 2 and the floor plate 3.

防振装置本体4は、台座2と床板3の間の複数の所望位置に設けられ、これらの複数の防振装置本体4により、床板3側の横揺れ振動が吸収されるようになっている。各防振装置本体4は、横揺れ振動の吸収する積層ゴム5と、この積層ゴム5の上下面部を押圧するように設けられる上下1組のネジ6と、積層ゴム5の破壊を防止するために設けられるストッパ装置7とから構成される。   The vibration isolator body 4 is provided at a plurality of desired positions between the pedestal 2 and the floor board 3, and the vibration vibration apparatus body 4 absorbs the rolling vibration on the floor board 3 side. . Each anti-vibration device body 4 prevents laminated rubber 5 from absorbing roll vibration, a pair of upper and lower screws 6 provided to press the upper and lower surfaces of the laminated rubber 5, and destruction of the laminated rubber 5. It is comprised from the stopper apparatus 7 provided in this.

積層ゴム5は、横揺れ振動が吸収できるように、ゴム質部5A内に複数の剛性の円板5Bが所定の間隔をおいて埋設された構成のものである。   The laminated rubber 5 has a configuration in which a plurality of rigid disks 5B are embedded in the rubber-like portion 5A at a predetermined interval so as to absorb rolling vibration.

上下1組のネジ6には、それぞれ積層ゴム5の上下面部を直接押圧する頭部6Aを備えている。   Each set of upper and lower screws 6 includes a head 6A that directly presses the upper and lower surfaces of the laminated rubber 5.

積層ゴム5は、この積層ゴム5に許容値以上の横揺れが生じた場合に、破壊しないようにストッパ装置7が設けられる。このストッパ装置7は、台座側ストッパ8および床板側ストッパ9との協働により、積層ゴム5の許容値以上の横揺れを防止するよう作用するものである。   The laminated rubber 5 is provided with a stopper device 7 so that the laminated rubber 5 does not break when the laminated rubber 5 rolls more than an allowable value. This stopper device 7 acts to prevent rolling of the laminated rubber 5 beyond the allowable value in cooperation with the base side stopper 8 and the floor board side stopper 9.

台座側ストッパ8は、有底筒状に設置されたもので、底部が台座2側に固定される。床板側ストッパ9は、有底筒状のものを逆さに設置されたもので、底部が床板3側に固定される。   The pedestal side stopper 8 is installed in a bottomed cylindrical shape, and the bottom is fixed to the pedestal 2 side. The floor plate-side stopper 9 is a bottomed cylindrical one installed upside down, and the bottom is fixed to the floor plate 3 side.

台座側ストッパ8および床板側ストッパ9の両筒状部の間には、環状弾性体(緩衝材)が設けられてあり、台座2側および床板3側の少なくとも一方が、左右もしくは前後に揺動することにより相互に弾力的に接触するようになる。従って、防振装置1によれば、特に横揺れ振動に対する防振作用により、運転室の横揺れ振動を吸収して運転室の居住性を改善することができるようになっている。
特開平10−280482号公報
An annular elastic body (buffer material) is provided between the cylindrical portions of the pedestal side stopper 8 and the floor board side stopper 9, and at least one of the pedestal 2 side and the floor board 3 side swings left and right or back and forth. By doing so, they come into elastic contact with each other. Therefore, according to the vibration isolator 1, it is possible to improve the comfortability of the driver's cab by absorbing the vibration of the driver's cab, particularly by the vibration proofing action against the roll vibration.
JP-A-10-280482

従来の防振装置1は、1つの防振装置本体4に1つの防振ゴム5を設けた構成である。この構成を油圧ショベル等の移動体に採用した場合、この移動体の重量や加速度が作用して、前後、左右の揺れが生じた場合には、相当強い作用力が掛かり、防振装置本体4の防振ゴム5が破壊される可能性がある。   The conventional vibration isolator 1 has a configuration in which one vibration isolator rubber 5 is provided on one vibration isolator main body 4. When this configuration is adopted in a movable body such as a hydraulic excavator, if the weight and acceleration of the movable body act to cause a back-and-forth and left-right swing, a considerably strong acting force is applied, and the vibration isolator body 4 The anti-vibration rubber 5 may be destroyed.

この破壊対策として、防振ゴム5の強靭性や強度を向上させた場合には、比較的強い横揺れ振動に対しては、破壊を防ぐことができるが、微小な横揺れ振動に対しては十分な振動吸収作用が得られない。従って、防振装置1によれば、比較的弱い横揺れ振動に対する防振作用が得られず、例えば車両等の移動体に搭載される制御機器等の機器に対して用いられる防振装置として使用することができなかった。   As a countermeasure against this damage, if the toughness and strength of the anti-vibration rubber 5 are improved, the breakage can be prevented against a relatively strong roll vibration. A sufficient vibration absorbing effect cannot be obtained. Therefore, according to the vibration isolator 1, an anti-vibration action against relatively weak roll vibration cannot be obtained, and for example, it is used as a vibration isolator used for equipment such as control equipment mounted on a moving body such as a vehicle. I couldn't.

また、強い横揺れ振動を受けて、台座側ストッパ8と床板側ストッパ9とが当接した場合には、積層ゴム5の横揺れが規制されるようになる。従って、積層ゴム5による横揺れ振動の吸収作用が得られなくなり、運転室の横揺れ振動が激しくなり、この運転室の居住性を損なっていた。   Further, when the base-side stopper 8 and the floor board-side stopper 9 are in contact with each other due to strong roll vibration, the roll of the laminated rubber 5 is regulated. Accordingly, the rolling vibration absorbing action of the laminated rubber 5 cannot be obtained, and the rolling vibration of the driver's cab becomes intense, impairing the comfort of the driver's cab.

本発明は、上記の事情に鑑みてなされたもので、比較的強い横揺れ振動や微小な横揺れ振動に対しても相応の振動吸収作用を得ることができるようにした防振装置を提供することを目的とする。   The present invention has been made in view of the above circumstances, and provides a vibration isolator capable of obtaining a corresponding vibration absorbing action even with respect to relatively strong roll vibration and minute roll vibration.

[第1の実施形態(図1〜図5)]
図1は、本発明の防振装置の第1の実施形態を示す概要図である。
[First Embodiment (FIGS. 1 to 5)]
FIG. 1 is a schematic view showing a first embodiment of the vibration isolator of the present invention.

図2は、図1のA部を拡大して示している。図3は、図1のB部を拡大図であり、図4は、図1に示す防振装置20Aの分解斜視図である。また、図5は、図1に示す防振装置20Aの動き規制ガイド部24の配置関係を示している。   FIG. 2 is an enlarged view of part A of FIG. 3 is an enlarged view of a portion B in FIG. 1, and FIG. 4 is an exploded perspective view of the vibration isolator 20A shown in FIG. FIG. 5 shows an arrangement relationship of the motion regulation guide portion 24 of the vibration isolator 20A shown in FIG.

この防振装置20Aは、車両等の移動体側に搭載され、制御機器等の機器を設置する機器設置基台21と、この機器設置基台21上において、この機器設置基台21の縦揺れおよび横揺れ振動成分を吸収するように設けられる振動吸収組立体22と、この振動吸収組立体22の縦揺れおよび横揺れ振動成分を吸収するように設けられる機器組立体23と、機器設置基台21側から急激に縦揺れ振動を受けた場合に、機器組立体23の安定保持を図るために設けられる複数、例えば4つの動き規制ガイド部24とから構成される。   The vibration isolator 20A is mounted on a moving body such as a vehicle, and a device installation base 21 on which devices such as control devices are installed. On the device installation base 21, the vertical vibration of the device installation base 21 and A vibration absorbing assembly 22 provided to absorb the rolling vibration component, a device assembly 23 provided to absorb the pitching and rolling vibration components of the vibration absorbing assembly 22, and a device installation base 21. It is composed of a plurality of, for example, four movement restriction guide portions 24 that are provided to stably hold the device assembly 23 when subjected to a pitching vibration suddenly from the side.

機器設置基台21は、この上面の相対向する2箇所に、上方に位置する振動吸収組立体22を直接保持する基台側保持具25と、機器組立体23を直接支持する複数、例えば4つの横揺れ振動吸収部材26を設けている。   The equipment installation base 21 includes a base side holder 25 that directly holds the vibration absorbing assembly 22 located above and two or more, for example, four, directly supporting the equipment assembly 23 at two opposite positions on the upper surface. Two roll vibration absorbing members 26 are provided.

基台側保持具25は、図2に示すように、振動吸収組立体22側の枠体側振動吸収手段29を保持固定したものである。   As shown in FIG. 2, the base side holder 25 holds and fixes the frame side vibration absorbing means 29 on the vibration absorbing assembly 22 side.

この基台側保持具25は、所定の間隔をとって起立して設けた2つの凸起体を1組として構成されたもので、機器設置基台21上面の相対向位置に2つ設けられる。これらの基台側保持具25は、例えば溶接B1により機器設置基台21側に固設される。   The base-side holding tool 25 is configured as a set of two protruding bodies provided upright at predetermined intervals, and two are provided at opposite positions on the upper surface of the equipment installation base 21. . These base side holding | maintenance tools 25 are fixedly installed in the apparatus installation base 21 side by welding B1, for example.

4つの横揺れ振動吸収部材26は、例えばゴム層内に剛性の円板を、所定の間隔をおいて、長手方向に重ね合わせるように複数埋設した積層ゴム製のものである。この横揺れ振動吸収部材26は、図1に示すように、機器設置基台21上面と、機器組立体23側との間に介挿されて設けられたものである。この横揺れ振動吸収部材26は、機器設置基台21側からの横揺れ振動成分が機器組立体23側へ伝わらないように振動吸収作用をなすものである。   The four roll vibration absorbing members 26 are made of laminated rubber, for example, in which a plurality of rigid discs are embedded in the rubber layer so as to overlap each other at a predetermined interval in the longitudinal direction. As shown in FIG. 1, the roll vibration absorbing member 26 is provided between the upper surface of the equipment installation base 21 and the equipment assembly 23 side. The roll vibration absorbing member 26 functions to absorb vibration so that the roll vibration component from the equipment installation base 21 side is not transmitted to the equipment assembly 23 side.

4つの横揺れ振動吸収体26は、図4に示すように、機器設置基台21の4隅部の底面側へ接着固定される。この横揺れ振動吸収部材26は、所要の弾性を有するものであるが、一定以上の横揺れが生じると復元力を失い変形してしまう。例えば図5の点線で示すように、各動き規制ガイド部24の弧状凹部243に接する位置までが、復元力を失わない範囲を示している。   As shown in FIG. 4, the four rolling vibration absorbers 26 are bonded and fixed to the bottom side of the four corners of the device installation base 21. The roll vibration absorbing member 26 has a required elasticity, but if a roll of a certain level or more occurs, the roll vibration absorbing member 26 loses its restoring force and deforms. For example, as indicated by a dotted line in FIG. 5, a range where the restoring force is not lost is shown up to a position where the movement restricting guide portion 24 is in contact with the arc-shaped concave portion 243.

そこで、横揺れ振動吸収部材26が、横揺れするいずれの方向に移動したとしても復元力を失わないように、機器設置台31の4隅部の動きが規制されるように動き規制ガイド部24が設けられる。   Therefore, the movement regulation guide section 24 is configured so that the movement of the four corners of the device installation table 31 is regulated so that the restoring force is not lost even if the roll vibration absorbing member 26 moves in any direction of rolling. Is provided.

これらの動き規制ガイド部24は、この弧状凹部243の凹面と、定位置に設置される機器設置台31の周縁との間を、図5に示すように、所要の間隙Dをおいて設けられる。この間隙Dは、機器設置台31に横揺れ振動が生じた際に、この機器設置台31を下方から支持する複数の横揺れ振動吸収部材26のそれぞれが横揺れしても、弾性範囲内に収まるように調整された寸法である。   These movement restriction guide portions 24 are provided with a required gap D between the concave surface of the arc-shaped concave portion 243 and the peripheral edge of the equipment installation base 31 installed at a fixed position, as shown in FIG. . The gap D is within the elastic range even when each of the plurality of roll vibration absorbing members 26 supporting the device installation table 31 rolls when roll vibration occurs on the device installation table 31. Dimensions adjusted to fit.

従って、横揺れ振動吸収部材26は、機器設置台31が横揺れして間隙Dの示す範囲まで移動したとしても自己復帰するため、機器設置台31が所定寸法以上に横揺れ振動することはない。   Accordingly, the roll vibration absorbing member 26 self-recovers even if the device installation base 31 rolls and moves to the range indicated by the gap D, so that the device installation base 31 does not roll and vibrate beyond a predetermined dimension. .

また、これらの動き規制ガイド部24は、後述する複数の縦揺れ振動吸収部材34により機器設置台31の縦揺れ振動を抑制させるために、振動吸収部材34の上端と接触した状態に保持させている。   In addition, these movement restriction guide portions 24 are held in contact with the upper end of the vibration absorbing member 34 in order to suppress the vertical vibration of the device installation table 31 by a plurality of vertical vibration absorbing members 34 described later. Yes.

具体的には図1および図4に示すように、機器設置台31の4隅を、4つの機器設置台側縦揺れ振動吸収部材34により挟み込んだ状態に保持される構成になっている。   Specifically, as shown in FIGS. 1 and 4, the four corners of the device installation table 31 are held in a state of being sandwiched by four device installation table side longitudinal vibration absorbing members 34.

この構成によれば、機器設置基台21側から縦揺れ振動が発生した際に、機器設置台31が上方に飛び上がるのが抑止され、機器設置台31および各動き規制ガイド部24の相互が衝突したり離脱するのを防止することができる。   According to this configuration, when longitudinal vibration is generated from the equipment installation base 21 side, the equipment installation base 31 is prevented from jumping upward, and the equipment installation base 31 and each movement restriction guide portion 24 collide with each other. Can be prevented from leaving or leaving.

従って、複数の横揺れ振動吸収部材26,機器設置台31および各動き規制ガイド部24の各部品のいずれもが損傷したり破壊されたりするのを防止できるようになっている。   Accordingly, it is possible to prevent the parts of the plurality of roll vibration absorbing members 26, the device installation table 31, and the movement restricting guide portions 24 from being damaged or destroyed.

振動吸収組立体22は、図1に示すように、機器設置基台21と、機器組立体23側との間にあって、方形状の中間枠体28と、この中間枠体28の周囲部の相対向する一側に設けられる2組の枠体側振動吸収手段29と、中間枠体28の周囲部にあって、機器組立体23を直接支持するように対向配置した2組の枠体側保持具30とを備えている。振動吸収組立体22の中間枠体28には、方形状の孔281が形成されている。   As shown in FIG. 1, the vibration absorbing assembly 22 is located between the equipment installation base 21 and the equipment assembly 23 side, and has a rectangular intermediate frame 28 and a relative portion of the periphery of the intermediate frame 28. Two sets of frame body side vibration absorbing means 29 provided on one side facing each other, and two sets of frame body side holding tools 30 which are disposed around the intermediate frame body 28 so as to directly support the device assembly 23.

機器組立体23は、方形状の機器設置台31と、この機器設置台31上に設置される各種制御機器等の機器32と、機器設置台31の周囲部にあって、振動吸収組立体22の複数の枠体側保持具30に保持されるように、この複数の枠体側保持具30に対向配置して設けられた機器設置台側振動吸収手段33と、複数の縦揺れ振動吸収部材34とを備えている。   The equipment assembly 23 is a square equipment installation base 31, equipment 32 such as various control equipment installed on the equipment installation base 31, and a vibration absorbing assembly 22 around the equipment installation base 31. The apparatus installation base side vibration absorbing means 33 provided so as to be opposed to the plurality of frame body side holders 30 so as to be held by the plurality of frame body side holders 30, and a plurality of longitudinal vibration absorption members 34, It has.

枠体側振動吸収手段29は、図2に示すように、機器設置基台21の上面の相対向する位置に、例えば溶接B2により固定される支持片27と、この支持片27の自由端の両側にそれぞれ突出させて設けた振動吸収部材35とより構成される。   As shown in FIG. 2, the frame-side vibration absorbing means 29 includes, for example, a support piece 27 fixed by welding B <b> 2 at opposite positions on the upper surface of the equipment installation base 21, and both sides of the free end of the support piece 27. And a vibration absorbing member 35 provided so as to protrude from each other.

振動吸収部材35は、具体的には、支持片27の両側に、接着して設けているが、支持片27側に図示しない貫通孔を設けて、1本の振動吸収部材35を、その長手方向から挿通させて、支持片27に接着させた構成であってもよい。   Specifically, the vibration absorbing member 35 is bonded and provided on both sides of the support piece 27, but a through hole (not shown) is provided on the support piece 27 side, and one vibration absorbing member 35 is arranged in the longitudinal direction. It may be configured to be inserted from the direction and adhered to the support piece 27.

また、振動吸収部材35は、横揺れ振動吸収体26と同様構成のもので、図2にし示すように、横揺れ振動成分Yを吸収する作用をなす一方、縦揺れ振動成分Zについて、振動吸収作用が得られるものである。   Further, the vibration absorbing member 35 has the same configuration as the roll vibration absorber 26 and, as shown in FIG. 2, functions to absorb the roll vibration component Y, while the vibration absorption component Z absorbs vibration. An effect is obtained.

枠体側保持具30は、図3に示すように、機器設置器台21側の機器設置台側振動吸収手段33を保持固定するものである。   As shown in FIG. 3, the frame-side holder 30 holds and fixes the device installation table side vibration absorbing means 33 on the device installation device table 21 side.

この枠体側保持具30は、所定の間隔をとって起立して設けた2つの凸起体を1組として構成されたもので、中間枠体28の周縁部の相対向位置に2つ設けられる。これらの枠体側保持具30は、例えば溶接B4により中間枠体28側に固設される。これらの枠体側保持具30には、機器設置台31側に設けられた機器設置台側振動吸収手段33の振動吸収部材37の端部が接合される。   This frame-side holder 30 is configured as a set of two protruding bodies provided upright at predetermined intervals, and two are provided at opposite positions on the peripheral edge of the intermediate frame 28. .

The end portions of the vibration absorbing member 37 of the device installation table side vibration absorbing means 33 provided on the device installation table 31 side are joined to the frame body side holding tools 30.

機器設置台31は、図4および図5に示すように、4隅部が円弧状に形成され、上面には、各種制御機器等の機器32が設置される。また、中間枠体28の周囲4隅部には、その上面に複数、例えば4つの縦揺れ振動吸収部材34が接着固定される。   As shown in FIGS. 4 and 5, the device installation base 31 has four corners formed in an arc shape, and devices 32 such as various control devices are installed on the upper surface. A plurality of, for example, four longitudinal vibration absorbing members 34 are bonded and fixed to the upper surface of the four corners around the intermediate frame 28.

機器設置台側振動吸収手段33は、図3に示すように、機器設置台31の周縁部の相対向する位置に、例えば溶接B3により固定される支持片38と、この支持片38の自由端の両側にそれぞれ突出させて設けた振動吸収部材37とより構成される。この機器設置台側振動吸収手段33は、枠体側振動吸収手段29と同様構成のものを採用している。   As shown in FIG. 3, the device installation table side vibration absorbing means 33 includes, for example, a support piece 38 fixed by welding B <b> 3 at opposite positions on the peripheral edge of the device installation table 31, and a free end of the support piece 38. And a vibration absorbing member 37 provided so as to protrude from both sides. This equipment installation base side vibration absorbing means 33 employs the same configuration as the frame side vibration absorbing means 29.

また、振動吸収部材37は、図3にし示すように、横揺れ振動成分Xを吸収する作用をなす一方で、縦揺れ振動成分Zについて振動吸収作用が得られるものである。   Further, as shown in FIG. 3, the vibration absorbing member 37 functions to absorb the rolling vibration component X, while obtaining the vibration absorbing action with respect to the longitudinal vibration component Z.

4つの縦揺れ振動吸収部材34は、動き規制ガイド部24の天井面部242側に接合して縦揺れ方向の振動成分を主として抑制し得るように設けられたものであるが、機器設置台31の一定の横揺れ振動成分(X、Y)を吸収する作用が得られる。   The four pitch vibration absorbing members 34 are provided so as to be able to mainly suppress vibration components in the pitch direction by being joined to the ceiling surface portion 242 side of the movement restricting guide portion 24, An action of absorbing a certain roll vibration component (X, Y) is obtained.

動き規制ガイド部24について、具体的に説明する。   The movement restriction guide part 24 will be specifically described.

動き規制ガイド部24は、図1および図4に示すように、機器組立体23側を機器設置基台21側へ保持させるために設けられるもので、床面部241、天井面部242および弧状凹部243が設けられる。   As shown in FIGS. 1 and 4, the movement regulation guide portion 24 is provided to hold the device assembly 23 side to the device installation base 21 side, and includes a floor surface portion 241, a ceiling surface portion 242, and an arcuate recess 243. Is provided.

動き規制ガイド部24の床面部241は、機器設置基台21の上面に固定される。また、この床面部241には、4つの動き規制ガイド部24が設置された状態で、図1,図4および図5に示すように、それぞれが内方へ向かうように切欠部2411が設けられる。これらの切欠部2411は、機器設置基台21の上面に設置される横揺れ振動吸収部材26の設置位置を避けて設けられる。   The floor surface portion 241 of the movement restriction guide portion 24 is fixed to the upper surface of the device installation base 21. Further, the floor surface portion 241 is provided with notches 2411 so as to be directed inward as shown in FIGS. 1, 4, and 5 in a state where the four movement restriction guide portions 24 are installed. . These notches 2411 are provided avoiding the installation position of the roll vibration absorbing member 26 installed on the upper surface of the equipment installation base 21.

動き規制ガイド部24の天井面部242は、機器設置台31を縦揺れ振動吸収部材34を介して機器設置基台21側に一定の押圧力が加えられるものである。この動き規制ガイド部24の天井面部242による押圧力により、機器設置台31が上方へ飛び上がるのを抑制する働きが得られる。   The ceiling surface portion 242 of the movement restricting guide portion 24 is configured to apply a constant pressing force to the device installation base 21 side through the longitudinal vibration absorbing member 34 of the device installation table 31. Due to the pressing force of the ceiling surface portion 242 of the movement restriction guide portion 24, a function of suppressing the device installation base 31 from jumping upward is obtained.

次に、防振装置20Aの作用を図1〜図5を参照して説明する。   Next, the operation of the vibration isolator 20A will be described with reference to FIGS.

車両等の移動体の機器設置基台21側からの横揺れ振動により、振動吸収組立体22側および機器組立体23側に対して、図1および図2に示すように、一方向の横揺れ振動成分X(図1の紙面左右方向および図2〜図4の左右斜め方向)が伝わった場合について説明する。   As shown in FIG. 1 and FIG. 2, rolling in one direction is caused with respect to the vibration absorbing assembly 22 side and the equipment assembly 23 side by rolling vibration from the equipment installation base 21 side of a moving body such as a vehicle. A case where the vibration component X (the horizontal direction in FIG. 1 and the diagonal direction in FIGS. 2 to 4) is transmitted will be described.

機器設置基台21側からの横揺れ振動成分Xは、直接に4つの横揺れ振動吸収部材26を介して機器組立体23側に伝わる。横揺れ振動成分Xを受けた横揺れ振動吸収部材26には、この横揺れ振動吸収部材26の中心軸と直交する方向に曲げの力が作用する。   The roll vibration component X from the device installation base 21 side is directly transmitted to the device assembly 23 side via the four roll vibration absorbing members 26. A bending force acts on the roll vibration absorbing member 26 that has received the roll vibration component X in a direction perpendicular to the central axis of the roll vibration absorbing member 26.

横揺れ振動吸収部材26は、受けた曲げの力を、この振動吸収部材26の特性により横揺れ振動成分Xを吸収する。   The rolling vibration absorbing member 26 absorbs the rolling vibration component X from the received bending force due to the characteristics of the vibration absorbing member 26.

従って、横揺れ振動成分Xは、機器組立体23側へは伝わらず、機器組立体23は横揺れ振動が抑制される。   Therefore, the roll vibration component X is not transmitted to the equipment assembly 23 side, and the roll vibration of the equipment assembly 23 is suppressed.

ここで、比較強い横揺れ振動を受けた場合を想定する。   Here, the case where comparatively strong roll vibration is received is assumed.

比較的強い横揺れ振動を受けた場合には、図2に示すように、機器設置基台21側から伝わる一部の横揺れ振動成分Xは、基台側保持具25を介して枠体側振動吸収手段29側に伝わる。この伝わった一部の横揺れ振動成分Xを受けた枠体側振動吸収手段29は、その振動吸収部材35の中心軸方向の横揺れ振動成分Xを受ける。この横揺れ振動成分Xを受けた振動吸収部材35は、受けた横揺れ振動成分Xの方向から振動吸収がなされない。   When subjected to relatively strong roll vibration, as shown in FIG. 2, a part of the roll vibration component X transmitted from the equipment installation base 21 side is subjected to frame side vibration via the base side holder 25. It is transmitted to the absorption means 29 side. The frame-side vibration absorbing means 29 that has received the transmitted part of the rolling vibration component X receives the rolling vibration component X in the central axis direction of the vibration absorbing member 35. The vibration absorbing member 35 that has received the rolling vibration component X does not absorb vibration from the direction of the received rolling vibration component X.

一方、振動吸収組立体22側においては、図3に示すように、中間枠体28が横揺れ振動成分Xを受けることにより、枠体側保持具30を介して機器組立体23の機器設置台側振動吸収手段33側へ作用力として伝わる。機器設置台側振動吸収手段33側に伝わった横揺れ振動成分Xは、振動吸収部材37の中心軸と直交する方向に曲げの力が作用する。この曲げの力が振動吸収部材37の特性により横揺れ振動成分Xを吸収する。   On the other hand, on the vibration absorption assembly 22 side, as shown in FIG. 3, the intermediate frame 28 receives the roll vibration component X, so that the device assembly 23 side of the device assembly 23 via the frame body side holding tool 30. It is transmitted to the vibration absorbing means 33 as an acting force. The rolling vibration component X transmitted to the device installation base side vibration absorbing means 33 side is subjected to a bending force in a direction orthogonal to the central axis of the vibration absorbing member 37. This bending force absorbs the rolling vibration component X due to the characteristics of the vibration absorbing member 37.

従って、横揺れ振動成分Xは、機器組立体23側へは伝わらず、機器組立体23は振動が抑制される。   Therefore, the roll vibration component X is not transmitted to the device assembly 23 side, and the device assembly 23 is suppressed from vibrating.

一方、機器設置基台21側から、振動吸収組立体22側および機器組立体23側に対して、横揺れ信号成分Xの方向とほぼ直交する方向の横揺れ振動成分Y(図1の奥行き機方向および図2〜図4の左右斜め方向)が伝わった場合について説明する。   On the other hand, from the equipment installation base 21 side to the vibration absorbing assembly 22 side and the equipment assembly 23 side, the roll vibration component Y (in the depth machine of FIG. 1) in a direction substantially perpendicular to the direction of the roll signal component X. The direction and the right and left diagonal directions of FIGS. 2 to 4 are transmitted.

機器設置基台21側からの振動成分XおよびYは、図1および図2に示すように、基台側保持具25を介して振動吸収組立体22の枠体側振動吸収手段29側に伝わる。この枠体側振動吸収手段29側に伝わった横揺れ振動成分Yは、振動吸収部材35の中心軸と直交する方向に曲げの力が作用する。振動吸収部材35側へ曲げの力が作用することにより、この振動吸収部材35の特性により横揺れ振動成分Yを吸収する。   As shown in FIGS. 1 and 2, the vibration components X and Y from the device installation base 21 side are transmitted to the frame-side vibration absorbing means 29 side of the vibration absorbing assembly 22 through the base-side holder 25. The rolling vibration component Y transmitted to the frame side vibration absorbing means 29 side is subjected to a bending force in a direction perpendicular to the central axis of the vibration absorbing member 35. When a bending force acts on the vibration absorbing member 35 side, the rolling vibration component Y is absorbed by the characteristics of the vibration absorbing member 35.

従って、この横揺れ振動成分Yは、振動吸収組立体22および機器組立体23側へは伝わらず、機器組立体23は振動が抑制される。   Therefore, the roll vibration component Y is not transmitted to the vibration absorbing assembly 22 and the device assembly 23 side, and the device assembly 23 is suppressed from vibrating.

なお、機器設置基台21側から伝わってくる横揺れ振動成分を、一方向の振動成分Xと、他方向の振動成分Yを想定して説明したが、両方の振動成分X,Yを同時に受けた場合にでも対応可能である。   The rolling vibration component transmitted from the equipment installation base 21 side has been described on the assumption of the vibration component X in one direction and the vibration component Y in the other direction, but both vibration components X and Y are received simultaneously. It is possible to cope with the case.

このように、機器設置基台21側から伝わってくる横揺れ振動X,Yに対して、横揺れ振動吸収部材26や、振動吸収組立体22および機器組立体23側にて枠体側振動吸収手段29および機器設置台側振動吸収手段33を設けたことにより、機器組立体23における横揺れ振動を防ぐことができる。   In this way, with respect to the rolling vibrations X and Y transmitted from the equipment installation base 21 side, the lateral vibration absorbing member 26, the frame body side vibration absorbing means on the vibration absorbing assembly 22 and the equipment assembly 23 side. 29 and the equipment installation table side vibration absorbing means 33 are provided, the rolling vibration in the equipment assembly 23 can be prevented.

次に、機器組立体23側が機器設置基台21側から縦揺れ振動成分Z(図1および図4の上下方向)を受けた場合について説明する。   Next, a case where the device assembly 23 side receives the longitudinal vibration component Z (vertical direction in FIGS. 1 and 4) from the device installation base 21 side will be described.

機器設置基台21側から機器組立体23側へ、図1に示すように、縦揺れ振動成分Zを受けると、4つの横揺れ振動吸収部材26は、縦方向に振動する。4つの横揺れ振動吸収部材26が縦方向に振動すると、振動抑制効果が少ないために機器組立体23の機器設置台31が、下方向から振動を受ける。この受けた振動成分は、動き規制ガイド部24により、4つの縦揺れ振動吸収部材34側を上方から押圧状態に保持していることから、機器組立体23の機器設置台31の跳ね上げが抑止される。   As shown in FIG. 1, when the vertical vibration component Z is received from the device installation base 21 side to the device assembly 23 side, the four roll vibration absorbing members 26 vibrate in the vertical direction. When the four roll vibration absorbing members 26 vibrate in the vertical direction, the device installation base 31 of the device assembly 23 receives vibration from below because the vibration suppressing effect is small. Since the received vibration component holds the four longitudinal vibration absorbing members 34 in a pressed state from above by the motion regulation guide portion 24, the apparatus assembly table 31 of the apparatus assembly 23 is prevented from jumping up. Is done.

従って、4つの横揺れ振動吸収部材26,機器設置台31および動き規制ガイド部24の相互が衝突したり離脱するのが防がれ、延いてはこれらの部品が損傷したり破壊されたりしない。   Accordingly, the four roll vibration absorbing members 26, the device installation base 31, and the movement regulating guide portion 24 are prevented from colliding with each other and separated from each other, so that these components are not damaged or destroyed.

なお、枠体側振動吸収手段29および機器設置台側振動吸収手段33側の各振動吸収部材35,37については、振動吸収作用を有するが、動き規制ガイド部24による機器組立体23の機器設置基台21側への保持作用により、振動吸収作用が働かない状態になっている。   Note that each of the vibration absorbing members 35 and 37 on the frame body side vibration absorbing means 29 and the equipment installation base side vibration absorbing means 33 has a vibration absorbing action, but the equipment installation base of the equipment assembly 23 by the movement regulation guide portion 24 is not limited. The vibration absorbing action does not work due to the holding action on the table 21 side.

なお、防振装置20Aによれば、機器設置基台21側からの縦揺れ振動に対して、機器組立体23側が飛び跳ねるようなことがないように、動き規制ガイド部24を設けた構成にしたが、防振装置20Aが、特に縦揺れ振動の惧れのない設備や手段に用いられる場合には、この動き規制ガイド部24は必ずしも必要ではない。   In addition, according to the vibration isolator 20A, the motion restriction guide portion 24 is provided so that the device assembly 23 side does not jump against the longitudinal vibration from the device installation base 21 side. However, in the case where the vibration isolator 20A is used for equipment or means that is not particularly susceptible to longitudinal vibration, the movement restriction guide portion 24 is not necessarily required.

また、縦揺れ振動を防ぐために設けられた動き規制ガイド部24の天井壁面部242と機器設置台31との間に設けた縦揺れ振動吸収部材34は、必ずしも機器設置台31の下面側に位置する横揺れ振動吸収部材26の設置位置に対応させて設ける必要はなく、任意の位置に複数個設ければよい。   Further, the longitudinal vibration absorbing member 34 provided between the ceiling wall surface portion 242 of the movement restriction guide portion 24 provided to prevent longitudinal vibration and the device installation base 31 is not necessarily positioned on the lower surface side of the device installation base 31. It is not necessary to provide the roll vibration absorbing member 26 corresponding to the installation position of the roll vibration absorbing member 26, and a plurality of them may be provided at arbitrary positions.

更に、縦揺れ振動を防ぐために設けられた動き規制ガイド部24の天井壁面部242と機器設置台31との間に設けた縦揺れ振動吸収部材34は、必ずしも必要ではなく、動き規制ガイド部24の天井面部242側を振動吸収性を有するゴム状のものを介在させてもよい。   Further, the vertical vibration absorbing member 34 provided between the ceiling wall surface portion 242 of the movement restriction guide portion 24 provided to prevent the vertical vibration and the device installation base 31 is not necessarily required, and the movement restriction guide portion 24 is not necessarily required. A rubber-like material having vibration absorption may be interposed on the ceiling surface portion 242 side of the.

次に、機器32が、その機械的作動により横揺れ振動を起こした場合について説明する。   Next, the case where the apparatus 32 causes roll vibration due to its mechanical operation will be described.

機器32が、横揺れ振動により、特に複雑な横揺れ振動成分XおよびYを発生して横揺れ振動を起こすと、機器32が、平面方向へ回動しようとする回動作用力が働く。この回動作用力は、機器設置台31側の機器設置台側振動吸収手段33および中間枠体28側の枠体側振動吸収手段29に伝わろうとするが、これらのそれぞれの振動吸収手段33および29は、横揺れ方向の振動を抑制するように働く。   When the device 32 generates a roll vibration by generating a particularly complicated roll vibration component X and Y due to the roll vibration, a turning action force that the device 32 tries to turn in a plane direction works. This rotational force is transmitted to the device installation table side vibration absorbing means 33 on the device setting table 31 side and the frame side vibration absorbing means 29 on the intermediate frame body 28 side. It works to suppress vibration in the rolling direction.

従って、機器32の作動により生じる作用力は、機器設置台側振動吸収手段33および中間枠体28側の枠体側振動吸収手段29による回動抑止作用により抑制される結果、機器32の作動に影響を及ぼさない。   Therefore, the acting force generated by the operation of the device 32 is suppressed by the rotation suppressing action by the device installation base side vibration absorbing means 33 and the frame side vibration absorbing means 29 on the intermediate frame body 28 side. As a result, the operation of the device 32 is affected. Does not affect.

このように、防振装置20Aによれば、機器設置台31と、この機器設置台31の下面側に円形状を有する端面が接合された横揺れ振動吸収部材26と、この振動吸収部材26の下面側に接合された機器設置基台21とを備え、横揺れ振動吸収部材26は、機器設置基台21側からの振動が吸収可能に設けられたものであって、機器設置基台21の上面に設けられ、機器設置台21側を直接保持する基台側保持具25と、機器設置基台21と機器設置台31との間に設けられる振動吸収組立体22と、機器設置台31側に設けられる機器設置台側振動吸収手段33とを備え、振動吸収組立体22は、中間枠体28と、この中間枠体28の周囲部にあって、基台側保持具25に保持されるように複数の枠体側振動吸収手段29と、中間枠体28の周囲部にあって、機器設置台側振動吸収手段33を保持する基台側保持具25を備え、機器設置基台21側の振動を枠体側振動吸収手段29および機器設置台側振動吸収手段33により振動吸収し得るように構成したから、機器設置基台21側が比較的強い横揺れ振動や微小な横揺れ振動をしても、複数の板体側振動吸収手段29および機器設置台側振動吸収手段33により振動が吸収され、機器設置台31側における振動が抑制されるので、機器設置台31に設置される機器32は振動による性能劣化を効率的に防止することができる。   Thus, according to the vibration isolator 20A, the device installation table 31, the roll vibration absorbing member 26 having a circular end face joined to the lower surface side of the device installation table 31, and the vibration absorbing member 26 The roll vibration absorbing member 26 is provided so as to be able to absorb vibration from the device installation base 21 side, and the device installation base 21 joined to the lower surface side. A base-side holder 25 that is provided on the upper surface and directly holds the equipment installation base 21 side, a vibration absorbing assembly 22 provided between the equipment installation base 21 and the equipment installation base 31, and the equipment installation base 31 side The vibration absorbing assembly 22 is held by the base side holder 25 at the periphery of the intermediate frame body 28 and the intermediate frame body 28. A plurality of frame side vibration absorbing means 29 and the intermediate frame 28 There is a base side holding tool 25 that is in the surrounding area and holds the equipment installation base side vibration absorbing means 33, and the vibration on the equipment installation base 21 side transmits the vibration on the frame side vibration absorbing means 29 and the equipment installation base side vibration absorbing means 33. Therefore, even if the equipment installation base 21 side is subjected to relatively strong roll vibration or minute roll vibration, the plurality of plate body side vibration absorption means 29 and the equipment installation base side vibration absorption means are provided. Since the vibration is absorbed by the device 33 and the vibration on the device installation table 31 side is suppressed, the device 32 installed on the device installation table 31 can efficiently prevent performance deterioration due to vibration.

[第2の実施形態(図6)]
次に、本発明の第2の実施形態を示す防振装置20Bを説明する。
[Second Embodiment (FIG. 6)]
Next, the vibration isolator 20B which shows the 2nd Embodiment of this invention is demonstrated.

この防振装置20Bについて、図1〜図5に示す防振装置20Aと同一部分に同一符号を附した図6を参照して説明する。   The vibration isolator 20B will be described with reference to FIG. 6 in which the same parts as those in the vibration isolator 20A shown in FIGS.

図6に示す防振装置20Bは、車両等の移動体側に搭載され、制御機器等の機器を設置する機器設置基台21と、この機器設置基台21上において、この機器設置基台21の横揺れ振動成分を吸収するように設けられる振動吸収組立体22と、機器組立体23とから構成される。   An anti-vibration device 20B shown in FIG. 6 is mounted on the side of a moving body such as a vehicle, and an equipment installation base 21 on which equipment such as control equipment is installed, and on the equipment installation base 21, the equipment installation base 21 The vibration absorbing assembly 22 is provided so as to absorb the rolling vibration component, and the device assembly 23 is configured.

機器設置基台21は、この上面の相対向する2箇所に、上方に位置する振動吸収組立体22を直接保持する基台側保持具25と、機器組立体23を直接支持する横揺れ振動吸収部材26を設けている。横揺れ振動吸収部材26は、機器設置基台21側の上面の4箇所(2箇所のみ図示)に、例えば溶接B5により接合された吸収部材保持台40と、機器設置台31側の下面に設けられる4箇所(2箇所のみ図示)の吸収部材保持台41との間に跨るように接合される。   The equipment installation base 21 has a base-side holder 25 that directly holds the vibration absorption assembly 22 positioned above and two roll vibration absorptions that directly support the equipment assembly 23 at two opposite positions on the upper surface. A member 26 is provided. The rolling vibration absorbing member 26 is provided on the upper surface on the equipment installation base 21 side (only two places are shown) on the lower surface on the equipment installation base 31 and the absorbing member holding base 40 joined by welding B5, for example. It joins so that it may straddle between the absorption member holding base 41 of four places (only two places are shown in figure).

4箇所の吸収部材保持台40は、この各吸収部材保持台40の上面がそれぞれ所望の角度に傾斜した傾斜面401を有している。これらの各吸収部材保持台40の傾斜面401に垂直に交わる方向(一点鎖線図示)の延長線上にコンプライアンスセンタPが得られるようになっている。   The four absorbing member holding bases 40 have inclined surfaces 401 in which the upper surface of each absorbing member holding base 40 is inclined at a desired angle. The compliance center P is obtained on an extension line in a direction (shown by an alternate long and short dash line) perpendicular to the inclined surface 401 of each absorbing member holding base 40.

このように、各横揺れ振動吸収部材26を、機器設置基台21上に設置するにあたり、各横揺れ振動吸収部材26の長手方向の中心軸をコンプライアンスセンタPに一致させた構成としたことにより、機器設置基台21側の複雑な横揺れ振動の動きを抑制することができる作用が得られる。   Thus, when each roll vibration absorbing member 26 is installed on the equipment installation base 21, the longitudinal center axis of each roll vibration absorbing member 26 is made to coincide with the compliance center P. Thus, an action capable of suppressing the movement of complicated roll vibration on the equipment installation base 21 side is obtained.

また、4箇所の吸収部材保持台41は、この各吸収部材保持台41の下面がそれぞれ、各吸収部材保持台40の傾斜面401とほぼ並行になるように傾斜面411を有している。   Further, the four absorbent member holding bases 41 have inclined surfaces 411 such that the lower surfaces of the respective absorbent member holding bases 41 are substantially parallel to the inclined surfaces 401 of the respective absorbent member holding bases 40.

このように、コンプライアンスセンタPを設けた構成としたことにより、横揺れ振動成分Yの方向を中心軸として、軸回りの横揺れ振動成分X、Yが加わった場合に、機器組立体23の機器設置台31の横揺れの際には、この機器設置台31がほぼ水平のままの状態に保持される。   As described above, by providing the compliance center P, when the roll vibration components X and Y around the axis are added with the direction of the roll vibration component Y as the central axis, the device of the device assembly 23 is provided. When the installation table 31 rolls, the device installation table 31 is held in a substantially horizontal state.

従って、制御機器等の機器が、特に水平状態に設置されるのが望ましい場合には、コンプライアンスセンタPを採用した防振装置に好適する。   Therefore, when it is desirable to install a device such as a control device in a horizontal state, the device is suitable for a vibration isolator using the compliance center P.

その他の構成については、防振装置20Aと同様であるので説明を省略する。   Since other configurations are the same as those of the vibration isolator 20A, description thereof is omitted.

次に、防振装置20Bの作用について、図6を参照して説明する。   Next, the operation of the vibration isolator 20B will be described with reference to FIG.

車両等の移動体の機器設置基台21側からの横揺れ振動により、振動吸収組立体22側および機器組立体23側に対して、一方向の横揺れ振動成分Xが伝わった場合について説明する。   A case will be described in which a rolling vibration component X in one direction is transmitted to the vibration absorbing assembly 22 side and the device assembly 23 side due to the rolling vibration from the device installation base 21 side of a moving body such as a vehicle. .

機器設置基台21側からの横揺れ振動成分Xは、直接に4つの横揺れ振動吸収部材26を介して機器組立体23側に伝わる。横揺れ振動成分Xを受けた基台側横揺れ振動吸収部材26は、この振動吸収部材26の中心軸と直交する方向に曲げの力が作用する。横揺れ振動吸収部材26は、受けた曲げの力を、この振動吸収部材26の特性により横揺れ振動成分Xを吸収する。   The roll vibration component X from the device installation base 21 side is directly transmitted to the device assembly 23 side via the four roll vibration absorbing members 26. The base side roll vibration absorbing member 26 that has received the roll vibration component X is subjected to a bending force in a direction perpendicular to the central axis of the vibration absorbing member 26. The rolling vibration absorbing member 26 absorbs the rolling vibration component X from the received bending force due to the characteristics of the vibration absorbing member 26.

従って、この振動成分Xは、機器組立体23側へは伝わらず、機器組立体23は横揺れ振動が抑制される。   Therefore, the vibration component X is not transmitted to the device assembly 23 side, and the device assembly 23 is suppressed from rolling vibration.

ここで、比較強い横揺れ振動を受けた場合を想定する。   Here, the case where comparatively strong roll vibration is received is assumed.

図3に示すように、機器設置基台21側から伝わろうと一部の横揺れ振動成分Xは、基台側保持具25を介して枠体側振動吸収手段29側に伝わる。この一部の横揺れ振動成分Xを受けた枠体側振動吸収手段29は、その振動吸収部材35の中心軸方向の横揺れ振動成分Xを受ける。この振動成分Xを受けた振動吸収部材35は、受けた横揺れ振動成分Xの方向から振動吸収がなされず、振動抑制作用がなされる。   As shown in FIG. 3, a part of the rolling vibration component X is transmitted to the frame-side vibration absorbing means 29 side via the base-side holder 25 even if it is transmitted from the device installation base 21 side. The frame-side vibration absorbing means 29 that has received this part of the rolling vibration component X receives the rolling vibration component X in the central axis direction of the vibration absorbing member 35. The vibration absorbing member 35 that has received the vibration component X does not absorb vibration from the direction of the received rolling vibration component X, and has a vibration suppressing action.

一方、振動吸収組立体22側においては、図3に示すように、その中間枠体28が横揺れ振動成分Xを受けることにより、枠体側保持具30を介して機器組立体23の機器設置台側振動吸収手段33側へ作用力として伝わる。機器設置台側振動吸収手段33側に伝わった横揺れ振動成分Xは、振動吸収部材37の中心軸と直交する方向に曲げの力が作用する。この振動吸収部材37側へ、曲げの力が作用することにより、この振動吸収部材37の特性により横揺れ振動成分Xを吸収する。   On the other hand, on the vibration absorbing assembly 22 side, as shown in FIG. 3, when the intermediate frame 28 receives the rolling vibration component X, the device installation base of the device assembly 23 via the frame-side holder 30. It is transmitted as an acting force to the side vibration absorbing means 33 side. The rolling vibration component X transmitted to the device installation base side vibration absorbing means 33 side is subjected to a bending force in a direction orthogonal to the central axis of the vibration absorbing member 37. When a bending force acts on the vibration absorbing member 37 side, the rolling vibration component X is absorbed by the characteristics of the vibration absorbing member 37.

従って、横揺れ振動成分Xは、機器組立体23側へは伝わらず、機器組立体23は振動が抑制される。   Therefore, the roll vibration component X is not transmitted to the device assembly 23 side, and the device assembly 23 is suppressed from vibrating.

一方、機器設置基台21側から、振動吸収組立体22側および機器組立体23側に対して、図1および図2に示すように、横揺れ振動成分Xの方向とほぼ直交する方向の振動成分(図示せず)が伝わった場合について説明する。   On the other hand, as shown in FIGS. 1 and 2, vibrations in a direction substantially perpendicular to the direction of the rolling vibration component X from the equipment installation base 21 side to the vibration absorbing assembly 22 side and the equipment assembly 23 side. A case where components (not shown) are transmitted will be described.

機器設置基台21側からの振動成分は、基台側保持部25を介して振動吸収組立体22の枠体側振動吸収手段29側に伝わる。この枠体側振動吸収手段29側に伝わった振動成分は、振動吸収部材35の中心軸と直交する方向に曲げの力が作用する。振動吸収部材35側へ曲げの力が作用することにより、この振動吸収部材35の特性により振動成分を吸収する。   The vibration component from the device installation base 21 side is transmitted to the frame side vibration absorbing means 29 side of the vibration absorption assembly 22 through the base side holding portion 25. The vibration component transmitted to the frame side vibration absorbing means 29 side is subjected to a bending force in a direction perpendicular to the central axis of the vibration absorbing member 35. When a bending force acts on the vibration absorbing member 35 side, the vibration component is absorbed by the characteristics of the vibration absorbing member 35.

従って、この振動成分は、振動吸収組立体22および機器組立体23側へは伝わらず、機器組立体23は振動が抑制される。   Therefore, the vibration component is not transmitted to the vibration absorbing assembly 22 and the device assembly 23 side, and the device assembly 23 is suppressed from vibrating.

なお、機器設置基台21側から伝わってくる横揺れ振動成分を一方向の横揺れ振動成分Xと、他方向の横揺れ振動成分Yを想定して説明したが、両方の振動成分X,Yを同時に受けた場合にでも対応可能である。   The rolling vibration component transmitted from the equipment installation base 21 side has been described assuming the rolling vibration component X in one direction and the rolling vibration component Y in the other direction. It is possible to respond even if you receive at the same time.

このように、機器設置基台21側から伝わってくる横揺れ振動成分X,Yに対して、横揺れ振動吸収部材26や、振動吸収組立体22および機器組立体23側にて振動吸収手段を設けたことにより、機器組立体23における横揺れ振動を防ぐことができる。   As described above, the vibration absorbing means 26 and the vibration absorbing assembly 22 and the device assembly 23 side are provided with vibration absorbing means for the rolling vibration components X and Y transmitted from the device installation base 21 side. By providing, the rolling vibration in the apparatus assembly 23 can be prevented.

次に、機器組立体23側が機器設置基台21側から縦揺れ振動成分Zを受けた場合について説明する。   Next, the case where the device assembly 23 side receives the longitudinal vibration component Z from the device installation base 21 side will be described.

機器設置基台21側から機器組立体23側へ、図6に示すように、縦揺れ振動成分Zを受けると、4つの横揺れ振動吸収部材26、枠体側振動吸収手段29および機器設置台側振動吸収手段33側の各振動吸収部材35,37共に十分な振動吸収作用が得られない。   As shown in FIG. 6, when receiving the longitudinal vibration component Z from the equipment installation base 21 side to the equipment assembly 23 side, the four lateral vibration absorbing members 26, the frame side vibration absorbing means 29, and the equipment installation base side The vibration absorbing members 35 and 37 on the vibration absorbing means 33 side cannot obtain a sufficient vibration absorbing action.

各横揺れ振動吸収部材26については、共通のコンプライアンスセンタP位置に対応した所定の傾斜角度をもって設けられたことにより、一定の縦揺れ振動成分Zが得られる。   Each roll vibration absorbing member 26 is provided with a predetermined inclination angle corresponding to a common compliance center P position, whereby a constant pitch vibration component Z is obtained.

従って、4つの横揺れ振動吸収部材26が、縦揺れ振動成分Zを受けると、その振動により加わる縦方向の力の横方向分力成分(図示せず)については、4つの横揺れ振動吸収部材26にて一定の吸収作用が得られる。   Therefore, when the four roll vibration absorbing members 26 receive the pitch vibration component Z, the four horizontal vibration component members (not shown) of the vertical force component (not shown) applied by the vibration are four. A constant absorption action is obtained at 26.

次に、機器32が、その機械的作動により横揺れ振動を起こした場合についての機器32への回動抑止作用については、防振装置20Aの場合と同様であるので説明を省略する。   Next, since the rotation suppression action to the apparatus 32 when the apparatus 32 causes roll vibration due to its mechanical operation is the same as that of the vibration isolator 20A, the description thereof is omitted.

防振装置20Bによれば、状機器設置台31と、この機器設置台31の下面側に円形状を有する端面が接合された横揺れ振動吸収部材26と、この振動吸収部材26の下面側に接合された機器設置基台21とを備え、横揺れ振動吸収部材26は、機器設置基台21側からの振動が吸収可能に設けられ、機器設置基台21上のほぼ中心線上に設定されるコンプライアンスセンタP位置に、機器設置基台21上面に設けられる横揺れ振動吸収部材26のコンプライアンスセンタPが一致するように横揺れ振動吸収部材26が設置された構成にしたから、機器設置基台21側からの比較的強い振動やあらゆる方向の振動成分に対して効率的に振動吸収する一方、横揺れ振動吸収部材26自体の耐振動強度も一層向上させることができる。   According to the vibration isolator 20 </ b> B, the equipment installation base 31, the roll vibration absorbing member 26 having a circular end face joined to the lower surface side of the equipment installation base 31, and the lower surface side of the vibration absorbing member 26 are provided. The roll vibration absorbing member 26 is provided so as to be able to absorb vibration from the device installation base 21 side, and is set substantially on the center line on the device installation base 21. Since the roll vibration absorbing member 26 is installed at the compliance center P position so that the compliance center P of the roll vibration absorbing member 26 provided on the upper surface of the device installation base 21 coincides, the device installation base 21 is provided. While effectively absorbing vibration from relatively strong vibration from the side and vibration components in all directions, the vibration resistance strength of the roll vibration absorbing member 26 itself can be further improved.

[第3の実施形態(図7)]
次に、本発明の第3の実施形態を示す防振装置20Cを説明する。
[Third Embodiment (FIG. 7)]
Next, a vibration isolator 20C showing a third embodiment of the present invention will be described.

この防振装置20Cについて、図1〜図5に示す防振装置20Aと同一部分に同一符号を附した図7を参照して説明する。   The vibration isolator 20C will be described with reference to FIG. 7 in which the same reference numerals are given to the same parts as those of the vibration isolator 20A shown in FIGS.

図7に示す防振装置20Cは、車両等の移動体側に搭載され、制御機器等の機器を設置する機器設置基台21と、この機器設置基台21上に設けられる複数の放射状の***部、例えば4方へ***する***部を備えた中間板体50と、この中間板体50が、横揺れ振動を受けた場合に、この横揺れ振動成分を吸収するように設けられる機器組立体23とから構成される。   An anti-vibration device 20C shown in FIG. 7 is mounted on a moving body side such as a vehicle, and a device installation base 21 on which devices such as control devices are installed, and a plurality of radial ridges provided on the device installation base 21 For example, an intermediate plate 50 having a raised portion that protrudes in four directions, and a device assembly 23 provided so as to absorb this roll vibration component when the intermediate plate 50 is subjected to roll vibration. It consists of.

機器設置基台21上に、この上面の相対向する2箇所に、上方に位置する中間板体50を直接保持する一対の基台側振動吸収手段51と、機器組立体23を直接支持する複数、例えば4つの横揺れ振動吸収部材26とが設けられる。   On the equipment installation base 21, a pair of base-side vibration absorbing means 51 that directly holds the upper intermediate plate 50 at two opposing positions on the upper surface, and a plurality of equipment assemblies 23 that directly support the equipment assembly 23 For example, four roll vibration absorbing members 26 are provided.

一対の基台側振動吸収手段51は、機器設置基台21側から所定の間隔をとって起立して設けた2つの凸起部511と、この凸起部511の相対向する側に設けた振動吸収部材512とを備えている。1対の基台側振動吸収手段51の各凸起部511は、例えば溶接B6により機器設置基台21側に固設される。   The pair of base-side vibration absorbing means 51 is provided on two protruding portions 511 provided upright from the device installation base 21 side at a predetermined interval, and on opposite sides of the protruding portions 511. And a vibration absorbing member 512. Each protruding portion 511 of the pair of base side vibration absorbing means 51 is fixed to the equipment installation base 21 side by welding B6, for example.

4つの横揺れ振動吸収部材26は、例えばゴム層内に剛性の円板を埋設した積層ゴム製のもので、機器設置基台21と機器組立体23側との間にあって、機器設置基台21上面に垂直状態に配置し、機器設置基台21側からの横揺れ振動成分Xが機器組立体23側へ伝わらないように振動吸収する作用をなすものである。   The four rolling vibration absorbing members 26 are made of, for example, laminated rubber in which a rigid disk is embedded in a rubber layer, and are between the equipment installation base 21 and the equipment assembly 23 side. It is arranged in a vertical state on the upper surface, and acts to absorb vibration so that the rolling vibration component X from the equipment installation base 21 side is not transmitted to the equipment assembly 23 side.

この4つの横揺れ振動吸収体26は、機器設置基台21の4隅部の底面側へ接着固定される。   The four rolling vibration absorbers 26 are bonded and fixed to the bottom side of the four corners of the device installation base 21.

中間板体50は、周囲部の相対向する側に設けられる***部501と、これらの***部501の突出方向とほぼ直交する方向に突出して設けられる溝付***部502を備える。この溝付***部502は、先端部にそれぞれ溝部5021が設けられる。また、このそれぞれの溝部5021には、機器組立体23側の機器設置台側振動吸収手段33の振動吸収部材37が結合保持される。   The intermediate plate 50 includes a raised portion 501 provided on opposite sides of the peripheral portion, and a grooved raised portion 502 provided so as to protrude in a direction substantially orthogonal to the protruding direction of these raised portions 501. Each grooved raised portion 502 is provided with a groove portion 5021 at the tip. Further, the vibration absorbing member 37 of the device installation base side vibration absorbing means 33 on the device assembly 23 side is coupled and held in each of the groove portions 5021.

また、中間板体50の各***部501は、各基台側振動吸収手段51の振動吸収部材512間に跨って結合保持される。   Further, each raised portion 501 of the intermediate plate 50 is coupled and held across the vibration absorbing members 512 of the base side vibration absorbing means 51.

機器組立体23は、機器設置台31と、この機器設置台31上に設置される各種制御機器等の機器32と、機器設置台31の周囲部にあって、対向配置した2組の機器設置台側振動吸収手段33とを備えている。   The device assembly 23 includes a device installation table 31, devices 32 such as various control devices installed on the device installation table 31, and two sets of device installations that are disposed around the device installation table 31 and face each other. Table-side vibration absorbing means 33 is provided.

その他の構成は、防振装置20Aの構成と同様であるので説明を省略する。   The other configuration is the same as the configuration of the vibration isolator 20A, and a description thereof will be omitted.

次に、防振装置20Cの作用について、図7を参照して説明する。   Next, the operation of the vibration isolator 20C will be described with reference to FIG.

車両等の移動体の機器設置基台21側からの横揺れ振動により、機器設置基台21側に対して、一方向の横揺れ振動成分Xが伝わった場合について説明する。   A case will be described in which a rolling vibration component X in one direction is transmitted to the equipment installation base 21 side due to roll vibration from the equipment installation base 21 side of a moving body such as a vehicle.

機器設置基台21側からの横揺れ振動成分Xは、直接に4つの横揺れ振動吸収部材26を介して機器組立体23側に伝わる。横揺れ振動成分Xを受けた横揺れ振動吸収部材26には、この振動吸収部材26の中心軸と直交する方向に曲げの力が作用する。横揺れ振動吸収部材26は、受けた曲げの力を、この振動吸収部材26の特性により横揺れ振動成分Xを吸収する。   The roll vibration component X from the device installation base 21 side is directly transmitted to the device assembly 23 side via the four roll vibration absorbing members 26. A bending force acts on the roll vibration absorbing member 26 that has received the roll vibration component X in a direction orthogonal to the central axis of the vibration absorbing member 26. The rolling vibration absorbing member 26 absorbs the rolling vibration component X from the received bending force due to the characteristics of the vibration absorbing member 26.

従って、この振動成分Xは、機器組立体23側へは伝わらず、機器組立体23は横揺れ振動が抑制される。   Therefore, the vibration component X is not transmitted to the device assembly 23 side, and the device assembly 23 is suppressed from rolling vibration.

ここで、比較強い横揺れ振動を受けた場合を想定する。   Here, the case where comparatively strong roll vibration is received is assumed.

比較強い横揺れ振動を受けた場合には、機器設置基台21側から伝わる一部の横揺れ振動成分Yは、基台側振動吸収手段51を介して中間板体50側に伝わる。基台側振動吸収手段51の振動吸収部材512は、この伝わった横揺れ振動成分Yを吸収する。   When subjected to comparatively strong roll vibration, a part of the roll vibration component Y transmitted from the equipment installation base 21 side is transmitted to the intermediate plate 50 side via the base side vibration absorbing means 51. The vibration absorbing member 512 of the base side vibration absorbing means 51 absorbs the transmitted rolling vibration component Y.

従って、横揺れ振動成分Yは、中間板体50側に伝わらなく、機器組立体23は振動が抑制される。   Therefore, the roll vibration component Y is not transmitted to the intermediate plate 50 side, and the vibration of the device assembly 23 is suppressed.

一方、機器設置基台21側から、中間板体50側および機器組立体23側に対して、横揺れ信号成分Yの方向とほぼ直交する方向の横揺れ振動成分Xが伝わった場合について説明する。   On the other hand, the case where the rolling vibration component X in the direction substantially orthogonal to the direction of the rolling signal component Y is transmitted from the device installation base 21 side to the intermediate plate 50 side and the device assembly 23 side will be described. .

機器設置基台21側からの横揺れ振動成分Xは、この機器設置基台21の基台側振動吸収手段51を介して中間板体50側へ伝わる。   The rolling vibration component X from the equipment installation base 21 side is transmitted to the intermediate plate 50 side through the base side vibration absorbing means 51 of the equipment installation base 21.

この中間板体50側へ伝わった横揺れ振動成分Xは、振動吸収部材37の中心軸と直交する方向に曲げの力が作用する。振動吸収部材37側へ曲げの力が作用することにより、この振動吸収部材37の特性により横揺れ振動成分Xを吸収する。   The rolling vibration component X transmitted to the intermediate plate 50 side is subjected to a bending force in a direction orthogonal to the central axis of the vibration absorbing member 37. When a bending force acts on the vibration absorbing member 37 side, the rolling vibration component X is absorbed by the characteristics of the vibration absorbing member 37.

従って、この横揺れ振動成分Xは、機器組立体23側へは伝わらず、機器組立体23は振動が抑制される。   Therefore, the roll vibration component X is not transmitted to the device assembly 23 side, and the device assembly 23 is suppressed from vibrating.

なお、機器設置基台21側から伝わってくる横揺れ振動成分を、一方向の横揺れ振動成分Xと、他方向の横揺れ振動成分Yを想定して説明したが、両方の横揺れ振動成分X,Yを同時に受けた場合にでも対応可能である。   Note that the roll vibration component transmitted from the equipment installation base 21 side has been described assuming that the roll vibration component X in one direction and the roll vibration component Y in the other direction are both. Even when X and Y are received at the same time, it can be handled.

このように、機器設置基台21側から伝わってくる横揺れ振動X,Yに対して、横揺れ振動吸収部材26や、中間板体50側および機器組立体23側にて振動吸収手段を設けたことにより、機器組立体23における横揺れ振動を防ぐことができる。   In this way, with respect to the roll vibrations X and Y transmitted from the equipment installation base 21 side, vibration absorption means are provided on the roll vibration absorbing member 26, the intermediate plate 50 side, and the equipment assembly 23 side. As a result, it is possible to prevent the rolling vibration in the device assembly 23.

次に、機器32が、その機械的作動により横揺れ振動を起こした場合についての機器32への回動抑止作用については、防振装置20Aの場合と同様であるので説明を省略する。   Next, since the rotation suppression action to the apparatus 32 when the apparatus 32 causes roll vibration due to its mechanical operation is the same as that of the vibration isolator 20A, the description thereof is omitted.

なお、防振装置20Cの横揺れ振動吸収部材26は、機器設置基台21上面に垂直状態に配置した構成であるが、第2の実施形態で採用したように、機器設置基台21上のほぼ中心線上に設定されるコンプライアンスセンタP(図示せず)位置に、機器設置基台21上面に設けられる複数の横揺れ振動吸収部材26のコンプライアンスセンタP(図示せず)が一致するように配置させることができる。   Note that the roll vibration absorbing member 26 of the vibration isolator 20C is arranged in a vertical state on the upper surface of the equipment installation base 21, but as employed in the second embodiment, the roll vibration absorption member 26 on the equipment installation base 21 is provided. Arranged so that the compliance centers P (not shown) of the plurality of roll vibration absorbing members 26 provided on the upper surface of the equipment installation base 21 coincide with the compliance center P (not shown) set substantially on the center line. Can be made.

このように、防振装置20Cによれば、機器設置台31と、この機器設置台31の下面側に一端面側が接合された複数の円柱状の横揺れ振動吸収部材26と、この複数の振動吸収部材26の下面側に他端面側が接合された機器設置基台21とを備え、複数の円柱状の横揺れ振動吸収部材26は、機器設置基台21側からの振動が吸収可能に設けられたものであって、機器設置基台21と機器設置台31との間に設けられる中間板体50と、機器設置基台21上面に設けられる基台側振動吸収手段51と、機器設置台31の周縁部に設けられる機器設置台側振動吸収手段33と、中間板体50の***部501を基台側振動吸収手段51により保持すると共に、中間板体50の溝付***部502により機器設置台側振動吸収手段33側を保持させた構成としたから、中間板体50は、単に平板状のものを加工すればよく、中間板体50の製作が容易となる一方で、防振装置20Cの組立性にも優れたものになる。   Thus, according to the vibration isolator 20C, the device installation table 31, the plurality of cylindrical roll vibration absorbing members 26 whose one end surface is joined to the lower surface side of the device installation table 31, and the plurality of vibrations The apparatus installation base 21 having the other end side joined to the lower surface side of the absorption member 26 is provided, and the plurality of columnar roll vibration absorption members 26 are provided so as to be able to absorb vibration from the apparatus installation base 21 side. An intermediate plate 50 provided between the equipment installation base 21 and the equipment installation base 31, a base-side vibration absorbing means 51 provided on the upper surface of the equipment installation base 21, and the equipment installation base 31. The device installation stand side vibration absorbing means 33 provided on the peripheral edge of the intermediate plate body 50 and the raised portion 501 of the intermediate plate body 50 are held by the base side vibration absorbing means 51, and the device is installed by the grooved raised portion 502 of the intermediate plate body 50. Hold the side vibration absorbing means 33 side. Because has a configuration, the intermediate plate member 50 may simply be processed to those of the flat, while the manufacture of the intermediate plate member 50 is facilitated, it becomes excellent in assembly property of the vibration damping device 20C.

また、中間板体50に設けた溝付***部502の溝5021は、必ずしも必要ではなく、機器組立体23側の機器設置台側振動吸収手段33の保持を可能にする構成であればよい。   Further, the groove 5021 of the grooved raised portion 502 provided in the intermediate plate 50 is not necessarily required as long as the device installation table side vibration absorbing means 33 on the device assembly 23 side can be held.

[第4の実施形態(図8,図9)]
次に、本発明の第4の実施形態を示す防振装置20Dを説明する。
[Fourth Embodiment (FIGS. 8 and 9)]
Next, a description will be given of a vibration isolator 20D according to a fourth embodiment of the present invention.

この防振装置20Dについて、図1〜図5に示す防振装置20Aと同一部分に同一符号を附した図8,図9を参照して説明する。   The vibration isolator 20D will be described with reference to FIGS. 8 and 9 in which the same parts as those in the vibration isolator 20A shown in FIGS.

図8,図9に示す防振装置20Dは、車両等の移動体側に搭載され、制御機器等の機器を設置するリング状の機器設置台70と、この機器設置台70の下面側に接合された断面が円形状で所要の厚さのリング状振動吸収部材71と、このリング振動吸収部材71の下面側に接合されたリング状の機器設置基台72とを備えている。   An anti-vibration device 20D shown in FIGS. 8 and 9 is mounted on a movable body side such as a vehicle, and is joined to a ring-shaped device installation table 70 on which devices such as control devices are installed, and a lower surface side of the device installation table 70. A ring-shaped vibration absorbing member 71 having a circular cross section and a required thickness, and a ring-shaped device installation base 72 joined to the lower surface side of the ring vibration absorbing member 71 are provided.

この機器設置台70は、上部に設置される機器32の形状に対応してリング状に形成されたものである。リング状振動吸収部材71は、リング状の機器設置基台72側からの縦横方向の振動の吸収が可能なように所要の厚さを有すると共に機器32の外形状に合致したリング状のもので、特に振動吸収性のよい材質、例えばゴムや積層ゴムが用いられる。   The device installation base 70 is formed in a ring shape corresponding to the shape of the device 32 installed in the upper part. The ring-shaped vibration absorbing member 71 is a ring-shaped member having a required thickness so as to be able to absorb vibrations in the vertical and horizontal directions from the ring-shaped device installation base 72 side and matching the outer shape of the device 32. In particular, a material having good vibration absorption, such as rubber or laminated rubber is used.

リング状振動吸収部材71は、あらゆる方向からの振動を吸収し得る形状であることから、リング状の機器設置基台72側からの振動に対して吸収作用を有する。   Since the ring-shaped vibration absorbing member 71 has a shape capable of absorbing vibrations from all directions, it has an absorbing action for vibrations from the ring-shaped device installation base 72 side.

また、リング状振動吸収部材71は、型成型やウォータージッェット工法により形成され易く、厚さについても振動の強さや振動数に応じた適宜の厚さ寸法や材料選定が可能であって、優れた振動吸収作用を発揮させることができる。   Further, the ring-shaped vibration absorbing member 71 is easily formed by molding or a water jet method, and the thickness can be appropriately selected in terms of thickness and material according to the strength and frequency of vibration. The vibration absorbing action can be exhibited.

次に、防振装置20Dの作用について、図8,図9を参照して説明する。   Next, the operation of the vibration isolator 20D will be described with reference to FIGS.

機器設置基台72が、例えば車両等の移動体に搭載され、振動源から種々の振動、すなわち一方向の横揺れ振動成分X,Yおよび縦揺れ振動成分Zが伝わった場合について説明する。   The case where the equipment installation base 72 is mounted on a moving body such as a vehicle and various vibrations, that is, the unidirectional roll vibration components X and Y and the vertical vibration component Z are transmitted from the vibration source will be described.

機器設置基台72側からの横揺れ振動成分XおよびYは、リング状振動吸収部材71を介して機器設置台70側に伝わる。横揺れ振動成分Xを受けた機器設置台70は、この機器設置台70の中心軸と直交する方向にせん断力が作用する。するとリング状振動吸収部材71は、受けたせん断力を、このリング状振動吸収部材71の特性により横揺れ振動成分XおよびYを吸収する。   The rolling vibration components X and Y from the device installation base 72 side are transmitted to the device installation table 70 side via the ring-shaped vibration absorbing member 71. The device installation table 70 that has received the rolling vibration component X is subjected to a shearing force in a direction perpendicular to the central axis of the device installation table 70. Then, the ring-shaped vibration absorbing member 71 absorbs the shear vibration component X and Y due to the received shear force due to the characteristics of the ring-shaped vibration absorbing member 71.

従って、この振動成分XおよびYは、機器32側へ伝わらず、機器32は横揺れ振動が抑制される。   Therefore, the vibration components X and Y are not transmitted to the device 32 side, and the device 32 is suppressed from rolling vibration.

また、リング状機器設置基台72側からの縦揺れ振動成分Zは、リング状振動吸収部材71の特性により縦揺れ振動成分Zを吸収する。   Further, the pitch vibration component Z from the ring-shaped equipment installation base 72 side absorbs the pitch vibration component Z due to the characteristics of the ring-shaped vibration absorbing member 71.

従って、この縦揺れ振動の振動成分Zは、機器32側へ伝わらず、機器32は縦揺れ振動が抑制される。   Therefore, the vibration component Z of the pitch vibration is not transmitted to the device 32 side, and the device 32 is suppressed from pitch vibration.

このように、防振装置20Dによれば、機器設置台31と、この機器設置台31の下面側に一端面側が接合された円筒状の振動吸収部材71と、この振動吸収部材71の下面側に他端面側が接合された機器設置基台72とを備え、振動吸収部材71は、機器設置基台72側からの振動が吸収可能に設けられたことを特徴とする構成であるから、機器設置基台72側から比較的強い横揺れ振動XおよびYを受けた場合にでも、機器32側に相応の振動が伝わる前に振動吸収作用を得ることができるので、機器32が比較的強い横揺れ振動や微小な縦揺れ振動を受けても相応の振動吸収作用が得られ、機器性能の劣化を防ぐことができる防振装置を提供することができる。   Thus, according to the vibration isolator 20D, the equipment installation base 31, the cylindrical vibration absorbing member 71 whose one end face is joined to the lower face side of the equipment installation base 31, and the lower face side of the vibration absorbing member 71 And the vibration absorbing member 71 is configured to be able to absorb vibration from the device installation base 72 side, so that the device installation base 72 is connected to the other end surface side. Even when relatively strong roll vibrations X and Y are received from the base 72 side, a vibration absorbing action can be obtained before the corresponding vibration is transmitted to the device 32 side, so that the device 32 has a relatively strong roll. It is possible to provide a vibration isolator capable of obtaining a corresponding vibration absorbing action even when subjected to vibration or minute pitch vibration, and preventing deterioration of device performance.

[第5の実施形態(図10,図11)]
次に、本発明の第5の実施形態を示す防振装置20Eを説明する。
[Fifth Embodiment (FIGS. 10 and 11)]
Next, the vibration isolator 20E which shows the 5th Embodiment of this invention is demonstrated.

この防振装置20Eについて、図8,図9に示す防振装置20Dと同一部分に同一符号を附した図10,図11を参照して説明する。   The vibration isolator 20E will be described with reference to FIGS. 10 and 11 in which the same parts as those in the vibration isolator 20D shown in FIGS.

図10,図11に示す防振装置20Eは、車両等の移動体側に搭載され、制御機器等の機器を設置するリング状の機器設置台80と、この機器設置台80の下面側に接合されたリング状の振動吸収部材81と、この振動吸収部材81の下面側に接合されたリング状の機器設置基台82とを備えている。   The vibration isolator 20E shown in FIGS. 10 and 11 is mounted on a movable body side such as a vehicle, and is joined to a ring-shaped device installation base 80 on which devices such as control devices are installed, and a lower surface side of the device installation base 80. A ring-shaped vibration absorbing member 81, and a ring-shaped device installation base 82 joined to the lower surface side of the vibration absorbing member 81.

リング状の機器設置基台82は、図11に示すようにすり鉢状の傾斜面821が設けられている。このすり鉢状の傾斜面821は、当該すり鉢状の傾斜面821に垂直に交わる方向(一点鎖線図示)の延長線上にコンプライアンスセンタPが得られるようになっている。   The ring-shaped device installation base 82 is provided with a mortar-shaped inclined surface 821 as shown in FIG. The mortar-shaped inclined surface 821 is configured such that the compliance center P is obtained on an extension line in a direction perpendicular to the mortar-shaped inclined surface 821 (shown by a one-dot chain line).

振動吸収部材81は、図11に示すように、リング状の機器設置基台82の傾斜面821に接合する逆すり鉢状の傾斜面811が設けられる。   As shown in FIG. 11, the vibration absorbing member 81 is provided with an inverted mortar-shaped inclined surface 811 that is joined to the inclined surface 821 of the ring-shaped device installation base 82.

リング状振動吸収部材81は、あらゆる方向からの振動を吸収し得る形状であることから、リング状の機器設置基台82側からの振動に対して吸収作用を有する。   Since the ring-shaped vibration absorbing member 81 has a shape capable of absorbing vibrations from all directions, it has an absorbing action for vibrations from the ring-shaped device installation base 82 side.

また、リング状振動吸収部材81は、コンプライアンスセンタPに適合するように、すり鉢状に形成されたものが用いられることから、縦,横方向からの振動成分に対しても効果的な振動吸収作用を発揮させられる。特に傾斜面811,821をコンプライアンスセンタPが適切な位置になるように設定することによって、横揺れ振動成分X,Yが伝わった際に、機器32は倒れるように振動することなく、水平な姿勢を保つことができる。   In addition, since the ring-shaped vibration absorbing member 81 is formed in a mortar shape so as to conform to the compliance center P, an effective vibration absorbing action against vibration components from the vertical and horizontal directions is used. Can be demonstrated. In particular, by setting the inclined surfaces 811 and 821 so that the compliance center P is at an appropriate position, when the roll vibration components X and Y are transmitted, the device 32 does not vibrate so as to fall down, and is in a horizontal posture. Can keep.

更に、リング状の振動吸収部材81は、型整形やウォータージッェット工法により形成され易く、厚さについても振動の強さや振動数に応じた適宜の厚さ寸法や材料選定が可能であって、優れた振動吸収作用を発揮させることができる。   Furthermore, the ring-shaped vibration absorbing member 81 can be easily formed by shaping or a water jet method, and the thickness can be appropriately selected according to the strength and frequency of vibration and material selection. An excellent vibration absorbing action can be exhibited.

リング状の振動吸収部材81は、図11に示すように、その一方の傾斜面811がリング状の機器設置基台82の傾斜面821接合される。また、リング状の振動吸収部材81の他方の傾斜面812に機器設置台80の一方の傾斜面801が接合される。   As shown in FIG. 11, one of the inclined surfaces 811 of the ring-shaped vibration absorbing member 81 is joined to the inclined surface 821 of the ring-shaped device installation base 82. In addition, one inclined surface 801 of the device installation table 80 is joined to the other inclined surface 812 of the ring-shaped vibration absorbing member 81.

その結果、機器設置台80の他方の面は、ほぼフラット面802が得られるようになっている。   As a result, a substantially flat surface 802 is obtained on the other surface of the device installation table 80.

次に、防振装置20Eの作用について、図10,図11を参照して説明する。   Next, the effect | action of the vibration isolator 20E is demonstrated with reference to FIG. 10, FIG.

車両等の移動体の機器設置基台82側から一方向の横揺れ振動成分X,Yおよび縦揺れ振動成分Zが伝わった場合について説明する。   A case will be described in which the rolling vibration components X and Y and the pitching vibration component Z in one direction are transmitted from the device installation base 82 side of a moving body such as a vehicle.

機器設置基台82側からの横揺れ振動成分XおよびYは、振動吸収部材81を介してリング状の機器設置台80側に伝わる。横揺れ振動成分Xを受けたリング状の機器設置台80は、リング状の振動吸収部材81による横揺れ方向の振動吸収特性により効率的な振動吸収作用が得られる。   The rolling vibration components X and Y from the device installation base 82 side are transmitted to the ring-shaped device installation table 80 side through the vibration absorbing member 81. The ring-shaped device installation base 80 that has received the rolling vibration component X can obtain an efficient vibration absorbing action due to the vibration absorbing characteristics in the rolling direction by the ring-shaped vibration absorbing member 81.

従って、機器32は、リング状の振動吸収部材81による横揺れ振動成分XおよびYの振動抑制作用により振動を受けない。   Therefore, the device 32 does not receive vibration due to the vibration suppressing action of the rolling vibration components X and Y by the ring-shaped vibration absorbing member 81.

また、リング状の機器設置基台82側からの縦揺れ振動成分Zは、振動吸収部材81の所要の厚さに基づく振動吸収特性により縦揺れ振動成分Zを吸収する。   Further, the longitudinal vibration component Z from the ring-shaped device installation base 82 side absorbs the longitudinal vibration component Z by the vibration absorption characteristic based on the required thickness of the vibration absorbing member 81.

従って、この縦揺れ振動の振動成分Zは、機器32側へ伝わらず、機器32は縦揺れ振動が抑制される。   Therefore, the vibration component Z of the pitch vibration is not transmitted to the device 32 side, and the device 32 is suppressed from pitch vibration.

このように、防振装置20Eによれば、機器設置台80と、この機器設置台80の下面側に一端面側が接合された円筒状の振動吸収部材81と、この振動吸収部材81の下面側に他端面側が接合された機器設置基台82とを備え、振動吸収部材81は、機器設置基台82側からの振動が吸収可能に設けられたものであって、機器設置基台82上のほぼ中心線上に設定されるコンプライアンスセンタp位置に、機器設置基台82上面に設けられる振動吸収部材のコンプライアンスセンタpが一致するように振動吸収部材81が設置された構成にしたから、機器設置基台82側からの比較的強い振動やあらゆる方向の振動成分に対して効率的に振動吸収する一方、振動吸収部材81自体の耐振動強度も一層向上させることができる。   Thus, according to the vibration isolator 20E, the device installation table 80, the cylindrical vibration absorbing member 81 whose one end surface is joined to the lower surface side of the device installation table 80, and the lower surface side of the vibration absorption member 81 The vibration absorbing member 81 is provided so as to be able to absorb vibrations from the device installation base 82 side, and is provided on the device installation base 82. Since the vibration absorbing member 81 is installed so that the compliance center p of the vibration absorbing member provided on the upper surface of the equipment installation base 82 coincides with the compliance center p set substantially on the center line, the equipment installation base is provided. While effectively absorbing vibration with respect to relatively strong vibration from the stand 82 and vibration components in all directions, the vibration resistance strength of the vibration absorbing member 81 itself can be further improved.

[第6の実施形態(図12,図13)]
次に、本発明の第6の実施形態を示す防振装置20Fを説明する。
[Sixth Embodiment (FIGS. 12 and 13)]
Next, a description will be given of a vibration isolator 20F showing a sixth embodiment of the present invention.

この防振装置20Fについて、図12,図13に示す防振装置20Dと同一部分に同一符号を附した図12,図13を参照して説明する。   The vibration isolator 20F will be described with reference to FIGS. 12 and 13 in which the same parts as those in the vibration isolator 20D shown in FIGS.

図12,図13に示す防振装置20Fは、車両等の移動体側に搭載され、制御機器等の機器を設置する機器設置台70と、この機器設置台70の上面に複数、例えば3つの円柱状の縦揺れ振動吸収部材90が等間隔に配置される。また、機器設置台70の下面側には、所要厚さを有し、主として縦揺れ振動成分を吸収するリング状振動吸収部材71が設けられる。   The vibration isolator 20F shown in FIGS. 12 and 13 is mounted on the side of a moving body such as a vehicle, and a plurality of, for example, three circles are provided on a device installation table 70 on which devices such as control devices are installed. Columnar longitudinal vibration absorbing members 90 are arranged at equal intervals. In addition, a ring-shaped vibration absorbing member 71 having a required thickness and mainly absorbing a longitudinal vibration component is provided on the lower surface side of the device installation base 70.

そして、リング状振動吸収部材71の下面側には、同じくリング状の基部910を備えた機器設置基台91が接合状態に設けられる。   Then, on the lower surface side of the ring-shaped vibration absorbing member 71, a device installation base 91 having a ring-shaped base portion 910 is provided in a joined state.

この機器設置基台91は、図12に示すように、機器設置基台91の基部911の周縁部から放射状に複数、例えば3つに等分された方向へ延出させた腕部912が設けられる。   As shown in FIG. 12, this equipment installation base 91 is provided with arm portions 912 that extend radially from the peripheral edge of the base 911 of the equipment installation base 91 in a direction equally divided into, for example, three. It is done.

この腕部912には、それぞれの延出方向とは逆の方向に折り曲げられた振動吸収部材押さえ部913がそれぞれ設けられ、3つの円柱状の縦揺れ振動吸収部材90を端面を機器設置台70上面に押圧保持するように設けられる。   The arm portion 912 is provided with a vibration absorbing member pressing portion 913 that is bent in a direction opposite to the extending direction thereof, and the three columnar longitudinal vibration absorbing members 90 are arranged on the end faces of the device installation base 70. It is provided so as to be pressed and held on the upper surface.

次に、防振装置20Fの作用について、図12,図13を参照して説明する。   Next, the effect | action of the vibration isolator 20F is demonstrated with reference to FIG. 12, FIG.

車両等の移動体の機器設置基台91側から横揺れ振動成分X,Yおよび縦揺れ振動成分Zが伝わった場合について説明する。   A case where the roll vibration components X and Y and the pitch vibration component Z are transmitted from the equipment installation base 91 side of a moving body such as a vehicle will be described.

機器設置基台91側からの横揺れ振動成分XおよびYは、リング状振動吸収部材81に伝わる。横揺れ振動成分XおよびYを受けたリング状振動吸収部材81は、横揺れ振動成分の吸収特性により横揺れ振動吸収作用が得られる。   The rolling vibration components X and Y from the equipment installation base 91 side are transmitted to the ring-shaped vibration absorbing member 81. The ring-shaped vibration absorbing member 81 that has received the rolling vibration components X and Y has a rolling vibration absorbing action due to the absorption characteristics of the rolling vibration component.

従って、横揺れ振動成分XおよびYは、機器32側へ伝わらず、機器32は横揺れ振動が抑制される。   Therefore, the rolling vibration components X and Y are not transmitted to the device 32 side, and the device 32 is suppressed from rolling vibration.

また、機器設置基台91側からの縦揺れ振動成分Zは、主として3つの円柱状の縦揺れ振動吸収部材90により吸収される。   Further, the pitch vibration component Z from the device installation base 91 side is mainly absorbed by the three columnar pitch vibration absorbing members 90.

従って、この縦揺れ振動の振動成分Zは、機器32側へ伝わらず、機器32は縦揺れ振動が抑制される。   Therefore, the vibration component Z of the pitch vibration is not transmitted to the device 32 side, and the device 32 is suppressed from pitch vibration.

このように、防振装置20Fによれば、機器設置台70と、この機器設置台70の下面側に一端面側が接合された円筒状の振動吸収部材71と、この振動吸収部材71の下面側に他端面側が接合された機器設置基台91とを備え、振動吸収部材71が機器設置台70の下面側に接触状態に保持されるように、機器設置台70の縦方向の動きを規制する縦方向動き規制ガイド部913を備え、また、機器設置台の横方向の動きを規制する横方向動き規制ガイド部912を備えた構成にしたから、機器設置基台91側が比較的強い横揺れ振動XおよびYを受けた場合にでも、機器32側に相応の振動が伝わる前に振動吸収作用を得ることができるので、機器32が比較的強い横揺れ振動や微小な横揺れ振動を受けても相応の振動吸収作用が得られ、機器性能の劣化を防ぐことができる。   Thus, according to the vibration isolator 20F, the device installation table 70, the cylindrical vibration absorbing member 71 whose one end surface is joined to the lower surface side of the device installation table 70, and the lower surface side of the vibration absorption member 71 And the device installation base 91 having the other end surface joined thereto, and the vertical movement of the device installation table 70 is regulated so that the vibration absorbing member 71 is held in contact with the lower surface side of the device installation table 70. Since the apparatus is provided with the longitudinal movement restriction guide part 913 and the transverse movement restriction guide part 912 that restricts the lateral movement of the equipment installation base, the equipment installation base 91 side has relatively strong roll vibration. Even when X and Y are received, the vibration absorbing action can be obtained before the corresponding vibration is transmitted to the device 32 side. Therefore, even if the device 32 receives relatively strong roll vibration or minute roll vibration. Proper vibration absorption is obtained It is possible to prevent the deterioration of the device performance.

また、機器設置基台91には、機器設置基台91が想定以上の大きな力で振動した場合にでも、この機器設置基台91に設けた動き規制ガイド部912および913の動き規制作用により、振動吸収部材71が破壊したり破損したりすることを防止できる。   In addition, even when the equipment installation base 91 vibrates with a greater force than expected, the equipment installation base 91 has a movement regulation action of the movement regulation guide portions 912 and 913 provided on the equipment installation base 91. It is possible to prevent the vibration absorbing member 71 from being broken or damaged.

更には、規制ガイド部912および913は、機器設置基台91の基部910の周縁部から一体的に突出させて設けられた構成であるから、折り曲げ加工等による加工が容易であると共に、寸法の調整も容易に行うことができる。   Furthermore, since the regulation guide portions 912 and 913 are provided so as to be integrally protruded from the peripheral edge portion of the base portion 910 of the equipment installation base 91, the processing by the bending processing or the like is easy, and the dimensions Adjustment can also be performed easily.

[第7の実施形態(図14,図15)]
次に、本発明の第7実施形態を示す防振装置20Gを説明する。
[Seventh Embodiment (FIGS. 14 and 15)]
Next, a description will be given of a vibration isolator 20G according to a seventh embodiment of the present invention.

この防振装置20Gについて、図12,図13に示す防振装置20Fと同一部分に同一符号を附した図14,図15を参照して説明する。   The vibration isolator 20G will be described with reference to FIGS. 14 and 15 in which the same parts as those in the vibration isolator 20F shown in FIGS.

図14,図15に示す防振装置20Gは、車両等の移動体側に搭載され、制御機器等の機器を設置する機器設置台100と、この機器設置台100の上面周辺部に複数、例えば4つの円柱状の振動吸収部材101(図15には3つのみ示す)が等間隔に配置される。   14 and 15 is mounted on the side of a moving body such as a vehicle, and a plurality of, for example, four, for example, four devices are installed in the device installation table 100 on which devices such as control devices are installed and the upper surface of the device installation table 100. Two columnar vibration absorbing members 101 (only three are shown in FIG. 15) are arranged at equal intervals.

また、機器設置台100の下面側には、リング状振動吸収部材71が設けられる。   Further, a ring-shaped vibration absorbing member 71 is provided on the lower surface side of the device installation table 100.

そして、リング状振動吸収部材71の下面側には、機器設置基台102が接合状態に設けられる。   And the apparatus installation base 102 is provided in the joining state on the lower surface side of the ring-shaped vibration absorbing member 71.

機器設置基台102は、図15に示すように、機器設置基台102の基部1020の周縁部から筒状に起立して設けた横方向動き規制ガイド部1021およびこの横方向動き規制ガイド部1021から内方側へ延出させて設けた縦方向動き規制ガイド部1022が設けられ、機器設置基台102が全体として断面コ字状に形成されたものである。   As shown in FIG. 15, the device installation base 102 includes a lateral movement restriction guide portion 1021 provided in a cylindrical shape from the peripheral edge of the base portion 1020 of the device installation base 102 and the lateral movement restriction guide portion 1021. A vertical movement restriction guide portion 1022 provided so as to extend inward from the inside is provided, and the device installation base 102 is formed in a U-shaped cross section as a whole.

この横方向動き規制ガイド部1021は、機器設置台100の横方向の動きを規制するために設けられたもので、機器設置台100の周縁部に所望の寸法まで近接させている。   The lateral movement restriction guide portion 1021 is provided to restrict the lateral movement of the device installation table 100 and is brought close to the peripheral edge of the device installation table 100 to a desired dimension.

また、縦方向動き規制ガイド部1022は、4つの円柱状の振動吸収部材101を端面を機器設置台100上面に保持するように接触状態に設けられる。   Further, the vertical direction movement restricting guide portion 1022 is provided in contact with the four columnar vibration absorbing members 101 so that the end surfaces thereof are held on the upper surface of the device installation table 100.

次に、防振装置20Fの作用について、図14,図15を参照して説明する。   Next, the effect | action of the vibration isolator 20F is demonstrated with reference to FIG. 14, FIG.

車両等の移動体の機器設置基台102側から横揺れ振動成分X,Yおよび縦揺れ振動成分Zが伝わった場合について説明する。   A case where the roll vibration components X and Y and the pitch vibration component Z are transmitted from the device installation base 102 side of a moving body such as a vehicle will be described.

機器設置基台102側からの横揺れ振動成分XおよびYは、振動吸収部材71に伝わる。横揺れ振動成分XおよびYを受けた状振動吸収部材71は、横揺れ振動成分の吸収特性により横揺れ振動吸収作用が得られる。   The rolling vibration components X and Y from the device installation base 102 side are transmitted to the vibration absorbing member 71. The vibration absorbing member 71 that has received the rolling vibration components X and Y has a rolling vibration absorbing action due to the absorption characteristics of the rolling vibration component.

従って、横揺れ振動成分XおよびYは、機器32側へ伝わらず、機器32は横揺れ振動が抑制される。   Therefore, the rolling vibration components X and Y are not transmitted to the device 32 side, and the device 32 is suppressed from rolling vibration.

また、機器設置基台102側からの縦揺れ振動成分Zは、主として4つの円柱状の振動吸収部材101により吸収される。   Further, the longitudinal vibration component Z from the device installation base 102 side is mainly absorbed by the four columnar vibration absorbing members 101.

従って、この縦揺れ振動の振動成分Zは、機器32側へ伝わらず、機器32は縦揺れ振動が抑制される。   Therefore, the vibration component Z of the pitch vibration is not transmitted to the device 32 side, and the device 32 is suppressed from pitch vibration.

このように、防振装置20gによれば、機器設置台100と、この機器設置台100の下面側に一端面側が接合された円筒状の振動吸収部材71と、この振動吸収部材71の下面側を下方より支えるように設けられる機器設置基台102と、機器設置基台102側の強い振動により、機器設置台100が振動吸収部材71側から離れないように機器設置基台102に、機器設置台100の縦方向の動きを規制する縦方向動き規制ガイド部1022を備え、また、機器設置台100の横方向の動きを規制する横方向動き規制ガイド部1021を備えた構成にしたから、機器設置基台102側が比較的強い横揺れ振動XおよびYを受けた場合にでも、機器32側に相応の振動が伝わる前に振動吸収作用を得ることができるので、機器32が比較的強い横揺れ振動や微小な横揺れ振動を受けても相応の振動吸収作用が得られ、機器性能の劣化を防ぐことができる。   Thus, according to the vibration isolator 20g, the device installation table 100, the cylindrical vibration absorbing member 71 whose one end surface is joined to the lower surface side of the device installation table 100, and the lower surface side of the vibration absorption member 71 Is installed on the equipment installation base 102 so that the equipment installation base 100 is not separated from the vibration absorbing member 71 side due to strong vibration on the equipment installation base 102 side. Since the apparatus includes the vertical movement restriction guide portion 1022 that restricts the vertical movement of the table 100 and the horizontal movement restriction guide portion 1021 that restricts the movement of the device installation table 100 in the horizontal direction. Even when the installation base 102 is subjected to relatively strong roll vibrations X and Y, a vibration absorbing action can be obtained before the corresponding vibration is transmitted to the device 32, so that the device 32 is relatively Vibration absorbing effect of correspondingly be subjected to rolling vibration or slight rocking vibration There are obtained, it is possible to prevent deterioration of the device performance.

なお、機器設置基台102には、機器設置基台102が想定以上の大きな力で振動した場合にでも、この機器設置基台102に設けた動き規制ガイド部1021および1022の動き規制作用により、振動吸収部材71が破壊したり破損したりすることを防止できる。   In addition, even when the equipment installation base 102 vibrates with a greater force than expected, the equipment installation base 102 has a motion regulation action of the motion regulation guide portions 1021 and 1022 provided on the equipment installation base 102. It is possible to prevent the vibration absorbing member 71 from being broken or damaged.

更には、規制ガイド部1021および1022は、機器設置基台102の基部1020の周縁部から一体的に突出させて設けられた構成であるから、例えば断面コの字形に形成された長尺のものを円形状に折り曲げ加工して用いる等、加工が容易であると共に寸法の調整も容易に行うことができる。   Furthermore, since the restriction guide portions 1021 and 1022 are provided so as to integrally protrude from the peripheral edge portion of the base portion 1020 of the equipment installation base 102, for example, a long one formed in a U-shaped cross section. For example, it is easy to process and be used to adjust the dimensions.

Side guard Ingredients 25, the absorbing member holder 40, 41 in the vibration isolator 20b, further may be respectively integrally to form the device installation base 21 of the protrusion portion 511 of the vibration isolator 20c.

また、機器設置基台102が、想定以上の大きな力で振動した場合にでも動き規制ガイド部1021および1022の動き規制作用により、振動吸収部材71が破壊したり破損したりすることを防止できる。   Further, even when the device installation base 102 vibrates with a force larger than expected, the vibration absorbing member 71 can be prevented from being broken or damaged by the movement restricting action of the movement restricting guide portions 1021 and 1022.

なお、本発明の防振装置20A〜20Gの構成によれば、機器設置基台21(72,82,91,102)側からの横揺れ振動を吸収する手段として、ゴムまたは積層ゴムを主体とした材質のものからなる振動吸収部材26(35,37,71,81,101)や、振動吸収手段29(33,51)を用いたが、図16(A)に示すように、機器設置基台21(72,82,91,102)に対するあらゆる方向の振動を抑制することができる振動を吸収するコイルバネ60を設けた構成とすることができる。   In addition, according to the structure of the vibration isolator 20A-20G of this invention, rubber | gum or laminated rubber is mainly used as a means to absorb the rolling vibration from the apparatus installation base 21 (72, 82, 91, 102) side. The vibration absorbing member 26 (35, 37, 71, 81, 101) and the vibration absorbing means 29 (33, 51) made of the selected material are used. As shown in FIG. It can be set as the structure which provided the coil spring 60 which absorbs the vibration which can suppress the vibration of all directions with respect to the stand 21 (72, 82, 91, 102).

このコイルバネ60は、防振装置20A〜20Cの中央軸Eを中心として、この機器設置基台21の上面側と機器設置台31の底面側との間に設置された比較的径大な吸振性を有する強靭なものである。また、このコイルバネ60は、機器設置基台21側の固有振動数や振動強度に応じた弾力係数や強度を適宜に選択することにより、1本のコイルバネ60により、横揺れ振動成分(X,Y)のみならず、縦揺れ振動成分(Z)にも対応可能にすることができる。   The coil spring 60 has a relatively large vibration absorbing property that is installed between the upper surface side of the device installation base 21 and the lower surface side of the device installation table 31 around the central axis E of the vibration isolation devices 20A to 20C. Is tough. In addition, the coil spring 60 is appropriately selected from the elastic coefficient and strength according to the natural frequency and vibration strength on the equipment installation base 21 side, so that the single coil spring 60 causes the rolling vibration component (X, Y). ) As well as the longitudinal vibration component (Z).

また、図16(B)に示すように、横揺れ振動吸収部材26に加えて、横向きに配置される振動を吸収する引張りまたは圧縮状態のコイルバネ61を設けた構成とすることができる。   Further, as shown in FIG. 16B, in addition to the roll vibration absorbing member 26, a coil spring 61 in a tension or compression state that absorbs vibrations arranged in the lateral direction can be provided.

このコイルバネ61を用いた場合には、防振装置20A〜20eの中央軸Eを中心として点対称の放射方向位置に複数、例えば3つのコイルバネ61(1つのみ図示)を設けた構成にするのが機器設置基台21にかかるバネ応力の関係からも望ましい。   When this coil spring 61 is used, a plurality of, for example, three coil springs 61 (only one is shown) are provided at point-symmetric radial positions about the central axis E of the vibration isolators 20A to 20e. Is desirable from the relationship of the spring stress applied to the equipment installation base 21.

コイルバネ61は、機器設置基台21の所定箇所と、機器設置台31の底面側周辺部にバネホルダ211および311をそれぞれ設け、この両ホルダ211,311間にコイルバネ61を懸架させた構成である。このコイルバネ61は、複数を用いることにより、機器設置基台21側の固有振動数や振動強度に応じた弾力係数や強度を適宜に選択して、横揺れ振動成分(X,Y)のみならず、縦揺れ振動成分(Z)にも十分対応可能にすることができる。   The coil spring 61 has a configuration in which spring holders 211 and 311 are respectively provided at predetermined locations of the device installation base 21 and at the bottom side peripheral portion of the device installation base 31, and the coil spring 61 is suspended between the holders 211 and 311. By using a plurality of coil springs 61, an elastic coefficient and strength corresponding to the natural frequency and vibration strength on the equipment installation base 21 side are appropriately selected, and not only the rolling vibration component (X, Y). Further, it is possible to sufficiently cope with the longitudinal vibration component (Z).
