【発明の詳細な説明】
本発明は、精密機器を防振支持する空気ばね装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air spring device for supporting precision instruments with vibration isolation.
従来、空気ばれ装置は第１図に示すように構成されてい

置される空気ばね６絋空気ばね本体４と上下方向の固有
−動数調整用の付加タンク５とから構成されている。Conventionally, an air baffle device has been constructed as shown in FIG. Fixed I in the 111th! The air spring 6 is disposed between the air spring 1 and the lower base 2, the air spring main body 4, and an additional tank 5 for adjusting the natural movement in the vertical direction.

ている。The air spring main body 4 has a diaphragm 6 slackly disposed between the upper part of the additional tank 5 and the support base 4a supporting the surface plate 1t to form an air chamber 7. The inside is connected through an orifice 8.
図中、９は付加タンク５内への空気供給孔で６９、図示

で心る。In the figure, reference numeral 9 denotes an air supply hole 69 into the additional tank 5, and although not shown, it is assumed that an air supply pipe is connected between it and the air source.
上記した従来の空気ばね装置には次のような欠点があり
た。The conventional air spring device described above has the following drawbacks.
■ ４１に空気ばね本体４の構造が複雑で′ｈ９、ダイ
ヤフラム６の堆付けが煩雑であるため、全体として鳥価
である。(4) The structure of the air spring main body 4 is complicated, and the mounting of the diaphragm 6 is complicated, so the overall price is low.

のばれ定数を小さくすることはできない。ばね定数を小
さくする手段として付加タンク５を高くして空気ばね全
体の高さＨを高くする方法があるが、安定性が悪くなシ
実用上好筐しくない。■Due to the structure of the diaphragm, it is not possible to make the deflection constant in the horizontal direction smaller than in the vertical direction. As a means of reducing the spring constant, there is a method of increasing the height H of the entire air spring by increasing the height of the additional tank 5, but this method is not suitable for practical use because the stability is poor.
■ 空気ばねの大部分は金属製であるため、重量が大き
く、取扱い上不便をきたす。■ Most air springs are made of metal, so they are heavy and difficult to handle.
本発明は、上記欠点を解消すべくなされ丸もので、構造

特徴とする鬼のである。The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide an air spring device 1 which is round, has a simple structure, and has a small spring constant in the vertical and horizontal plane directions. This is characterized by the fact that one tire t1 is arranged between the tire t1 so that its side surface becomes a load-receiving surface, and air is sealed inside the tire.
以下、本発明ｔＥＫ示した実施例につき説明する。第２
１１は本発明の一実施例を示すものである。Examples illustrating the present invention will be described below. Second
11 shows one embodiment of the present invention.
第２図において、１０はタイヤでＴｏシ、ゴムチ、−プ
１１と、その上に設けられたゴム外皮１２とから構成さ
れている。In FIG. 2, a tire 10 is composed of a toe, a rubber tip, a tip 11, and a rubber outer skin 12 provided thereon.

うＫされている。A stopper A is installed between the tire 10 surface plate 16 and the lower pace 14.
15 and an auxiliary stand 16 so that its side surface serves as a load receiving surface. The stopper 15 is a surface plate 16
On the lower surface, the auxiliary stand 16 is fixed to the upper surface of the lower base 14, and the stopper 15 is formed in a nine-circle shape with a surface 15a in contact with the tire 10 being an inclined surface. The rubber outer skin of the tire 10 at the contact portion (beat portion) with the stopper 15 is peeled off so that the rubber tube 11 inside the tire directly contacts the inclined surface 158 of the stopper 15.

うにされている。An air supply valve 17 provided on the inner periphery of the tire 10 is connected to an air supply pipe 18tii installed through the lower part of the auxiliary stand 16. A cylindrical body 19 having a diameter is fixedly installed, and this cylindrical body 19
The inner peripheral surface of the rubber tube 11 of the tire 10 is pressed down by the rubber tube 11 of the tire 10.

れる。When using the air spring device with the above configuration, a plurality of tires are mounted on one surface plate 16 at appropriate intervals, and an air supply pipe is connected to each tire to maintain the required pressure. Air is enclosed. Equipment to be vibration-proofed is placed on the surface plate 16.

度を適宜変化させることによシばね定数を調整すること
ができる。According to the above embodiment, since tires used as automobile wheels can be used, the structure can be easily and inexpensively constructed. 1+ Since the tire that acts as an air spring is made of rubber, the spring constant not only in the vertical direction but also in the horizontal direction is small, and the spring stiffness is soft. In particular, peel off the bead part of the rubber outer skin of the tire 10, and
5 is in direct contact with the rubber tube 11, which is softer than the outer skin 12, so that a softer spring stiffness can be obtained. Furthermore, the spring constant can be adjusted by appropriately changing the angle of inclination of the inclined surface 15a of the stopper 15.
第３図は本発明の他の実施例を示す図で６９、第２図と
共通する部分には同一符号を付している。FIG. 3 is a diagram 69 showing another embodiment of the present invention, and parts common to those in FIG. 2 are given the same reference numerals.
この実施例が前記第２図の実施例と相違するとζろは、
止金具１５に対するタイヤ１０の接触部の構造と、タイ
ヤのゴムチューブ１１内周面を押える円筒体１９の固定
位置である。If this embodiment is different from the embodiment shown in FIG.
These are the structure of the contact portion of the tire 10 with the stopper 15 and the fixed position of the cylindrical body 19 that presses the inner peripheral surface of the rubber tube 11 of the tire.
即ち、タイヤのゴム外皮のビート部１２ａｔ−剥離せず

てばね定数が若干大きくなるが、構成が簡略化されかつ
竪固である。また、ばね定数が大きくなる分だ１、定盤
１６上に大きな荷重を加えることができる。That is, the structure is such that the stopper 15 comes into contact with the bead part 158 of the rubber outer skin of the tire without peeling off at the bead part 12at. If this is done, the spring constant will be slightly larger than that of the embodiment shown in FIG. 2, but the structure will be simplified and more rigid. Furthermore, since the spring constant is increased, a large load can be applied to the surface plate 16.
また円筒体１９は止金具１５に固定されているが、これ
は補助台１５に固定したものと作用効果上の差異ｔｉｆ
’ｔとんどない。Further, the cylindrical body 19 is fixed to the stopper 15, but this is different from the one fixed to the auxiliary stand 15 in terms of operation and effect.
'It's ridiculous.

る。In addition, in the present invention, the auxiliary stand 16 is provided for arranging the air supply pipe 18, and may be omitted depending on the case.
4, which can be omitted if the surface plate 16t is placed directly on the tire 10. In short, one invention line, tire 10,
It is arranged so that its side surface becomes a load receiving surface.

。As described above, the air spring device according to the present invention is constructed by arranging a tire between a surface plate and a lower base so that its side surface becomes a load receiving surface, and completely filling the tire with air. It has the advantage that it has a simple structure, can be manufactured at low cost, and has soft spring stiffness in the vertical, downward and horizontal directions. Further, according to the present invention, since a tire is used as the air spring, the weight is lighter than the air spring of the conventional structure shown in FIG. Therefore, if the weight of the vibration isolation system is restricted, the weight of the surface plate can be increased accordingly, so the vibration amplitude of the surface plate can be reduced by Fig. 9 It is possible to obtain the effect of increasing the
