本発明は、圧縮機から地面に伝わる振動を小さくし得る
ようにした圧縮機の支持装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a support device for a compressor that can reduce vibrations transmitted from the compressor to the ground.
圧縮機の運転中に発生する振動には、低周波振動と高周
波振動があるが、この振動を吸収する機構としての圧縮

ばねコを介してケース３に吊下スるとともに、このケー

ことができても、圧縮機本体ｌとケース３の間に相対運
動が生じ、このため圧縮機本体／とケース３を結ぶパイ
プが折れてしまうことがあり、設計上問題である。The vibrations that occur during compressor operation include low-frequency vibrations and high-frequency vibrations.The compressor support device, which serves as a mechanism for absorbing these vibrations, is designed to support the compressor body l, as shown in Figure 1. It is suspended from the case 3 via a spring, and the case 3 is supported by a fixed side via a spring S, and this support device is capable of damping vibrations of the compressor main body l. Even if this is possible, a relative movement occurs between the compressor main body 1 and the case 3, which may cause the pipe connecting the compressor main body/and the case 3 to break, which is a design problem.
そこで第一図に示すように、圧縮機本体／とケース３を
連結杆６で固定し、これを固定側グにばねＳを介して支
持するようにした支持装置も提案されたが、この場合に

機本体ｌとケース３を結ぶバイブの折れる事故が生じる

のばねＫよって支持されるので、圧縮機本体ｌの振動を
減衰させる効果も少なく、圧縮機から出る振動を規定値
に抑えることがむづかしい。Therefore, as shown in Figure 1, a support device was proposed in which the compressor main body/case 3 is fixed with a connecting rod 6, and this is supported on the fixed side via a spring S. Since the compressor main body L and case 3 move together, there is no chance of the vibrator connecting the compressor main body L and case 3 breaking. Therefore, since it is supported, the effect of damping the vibrations of the compressor main body l is small, and it is difficult to suppress the vibrations emitted from the compressor to a specified value.
本発明は上記した点に鑑みてなされたもので、圧縮機本

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-mentioned points, and the integral structure of the compressor body and case is supported by a spring via an intermediate support, thereby damping vibrations transmitted from the compressor body to the ground, thereby reducing noise. An object of the present invention is to provide a support device for a compressor that prevents the occurrence of.
本発明の目的は、支持体を固定側にばね支持すの式を満

うにした圧縮機の支持装置によって達成される。The object of the present invention is achieved by a compressor support device in which vibrations of the compressor main body are damped by setting the support body to a value that satisfies the equation of spring support on the fixed side.
以下本発明の一実施例を図面につき説明する。 An embodiment of the present invention will be described below with reference to the drawings.
なお第３図において第一図と同一部材については同一符
号を付す。In FIG. 3, the same members as in FIG. 1 are given the same reference numerals.

上記支持板１０は、ばね／１． ／ｊを介して固定側ｌ
にばね支持されている。In FIG. 3, reference numeral 10 denotes a support plate for the compressor, and a case 3 is supported by springs on this support plate IO via springs //, //. A compressor main body is fixed inside the case 3 via a connecting rod. Further, the support plate 10 has a spring/1. Fixed side l via /j
Spring supported.
すなわち圧縮機本体／は、支持板１０にばね支持される
とともに固定側ダにもばね支持されており、一段にばね
支持されて防振効果を上げるようにしている。That is, the compressor main body is supported by a spring on the support plate 10 and also supported by a spring on the stationary side, so that the compressor body is further supported by a spring to improve the vibration-proofing effect.
一方上記形式の支持装置を用いて実験した結果、ばね／

合に、圧縮機から支持板への振動伝達率が周波いて最大
値忙なることが判った。It has been found that when the mass of the support plate 10 is Ml and the mass of the compressor is M, the vibration transmission rate from the compressor to the support plate varies in frequency and reaches its maximum value.
そして一つの固有振動数／、 、 ｆ、の５ち支持板に

, must be at a value far from to.
すなわち電源周波数をｆとした場合に

する必要がある。That is, when the power supply frequency is f, it is necessary to avoid 0, k < f/f, and < F.
上式より

値にｆ、を設定する必要がある。From the above equation, it is necessary to set f to a value that satisfies the following.
上式より ｆ、＜３左 ｌコｏ ＜ ｆ。From the above formula f, <3 left l ko < f.

、静かな運転状態を保ち得るという効果を奏する。As described above, according to the present invention, by specifying the spring constant of the spring for spring supporting the support body on the fixed side with respect to the mass of the support plate, the natural frequency can be kept low. By reducing the vibrations transmitted from the ground to the ground, noise caused by high-frequency vibrations such as metallic sounds, and noise caused by low-frequency vibrations such as whining noise, do not leak out of the case, allowing quiet operation to be maintained. This effect is achieved.
