振動の減衰及びバネ自体のサージング周波数のコントロ
ールをバネに装着した細いコイルバネによって行ない、
圧縮機の運転音を減減少せしめるものである。[Detailed description of the invention] This invention uses a spring to attenuate vibrations from an electric compression element transmitted by an open support spring to a support device for the compressor, particularly the electric compression element body, and to control the surging frequency of the spring itself. It is carried out by a thin coil spring attached,
This reduces the operating noise of the compressor.
従来の圧縮機における電動圧縮要素本体の支持装置の代
表例を第３図に示すと、圧縮要素、電動要素、（図示し
せず）を保持する枠体４にネジ穴、突起などの枠体側係
止部６を設け、また、ケース１にも同様の機能をもった
ケース側係止部７を設け、これらの両係上部を介して、
バネにより電動圧縮要素本体がケースに弾性支持されて
いる。FIG. 3 shows a typical example of a support device for an electric compression element body in a conventional compressor. A frame body 4 that holds a compression element, an electric element, (not shown) has screw holes, protrusions, etc. on the frame side. A locking portion 6 is provided, and a case-side locking portion 7 having a similar function is also provided on the case 1, and through both of these locking portions,
The electric compression element main body is elastically supported by the case by the spring.
このような支持装置においては電動圧縮要素本体で生じ
た振動がバネを介してケース１に伝わり、ケース１から
放射される騒音が大きくなってしまうという欠点があっ
た。Such a support device has a disadvantage in that vibrations generated in the electric compression element main body are transmitted to the case 1 via the spring, and the noise radiated from the case 1 becomes large.
また、バネの設計時に電動部の回転周波数及びその高次
周波数とバネ自体のサージング周波数を一致させないた
め、いちいちそれなりの配慮をしなければならなかった
。Furthermore, when designing the spring, certain considerations had to be made to ensure that the rotational frequency of the motorized part and its higher-order frequency did not match the surging frequency of the spring itself.
この考案はこのような欠点を除去することを目的とする
ものである。This invention aims to eliminate such drawbacks.
第１図において、密閉ケース１内部には、圧縮部２と、
電動部３と、こ、れらを一体的に固定する枠体４とを有
した電動圧縮要素本体５が収納され、この電動圧縮要素
本体５は、上記枠体４に設けられた係止部６と、上記ケ
ース１内壁面にこれと対をなすようにして設けられたも
う一方の係止部７と、これら両係止部６，７間に装着さ
れたコイルバネ８とにより弾性的に支持されている。In FIG. 1, inside the sealed case 1, there is a compression section 2,
An electric compression element main body 5 having an electric part 3 and a frame body 4 that integrally fixes them is housed, and this electric compression element body 5 is connected to a locking part provided on the frame body 4. 6, another locking part 7 provided on the inner wall surface of the case 1 to form a pair with this, and a coil spring 8 installed between both these locking parts 6 and 7. has been done.
そして上記コイルバネ８は第２図に示すとおり、細径の
コイルバネ９が密に螺装されており、その細径コイルバ
ネ９の巻径は上記コイルバネ８の線径より僅かに大きく
なっている。As shown in FIG. 2, the coil spring 8 is tightly threaded with a thin coil spring 9, and the winding diameter of the thin coil spring 9 is slightly larger than the wire diameter of the coil spring 8.
そして、圧縮機を運転すると電動圧縮要素本体５で生じ
た振動は、枠体の係止部６からコイルバネ８に伝達され
るが、コイルバネ８と細径コイルバネ９との摩擦によそ
の振動エネルギは一部摩擦エネルギに変換され、然も、
細径のコイルバネ９により共振周波数を変えることがで
きる。When the compressor is operated, the vibration generated in the electric compression element body 5 is transmitted from the locking part 6 of the frame to the coil spring 8, but the vibration energy is due to the friction between the coil spring 8 and the small diameter coil spring 9. Some of it is converted into frictional energy, but
The resonance frequency can be changed by the small diameter coil spring 9.
したがって、ケース１に伝達される振動エネルギは減衰
効果ならびに共振点のずれにより減少され騒音を低下さ
せる。Therefore, the vibration energy transmitted to the case 1 is reduced by the damping effect and the shift of the resonance point, thereby reducing noise.
特に一般の圧縮機においてはＩＫＨｚ以上の騒音に対し
て効果がある。It is particularly effective against noise of IKHz or higher in general compressors.
この考案は以上のように、電動圧縮要素本体を弾性支持
するコイルバネに細径のコイルバネを密に螺装させたの
で騒音の低下を計ることができるとともに、細径のコイ
ルバネの線径あるいは螺装長さを変えることにより支持
体であるコイルバネのサージング周波数を簡単に変える
ことができ、電動部の回転周波数およびその高次周波数
とずらして共振など容易に防止することができる。As described above, this invention has a small diameter coil spring tightly threaded onto the coil spring that elastically supports the electric compression element main body, so it is possible to reduce noise. By changing the length, the surging frequency of the coil spring that is the support body can be easily changed, and resonance can be easily prevented by shifting the rotational frequency of the motorized part and its higher-order frequencies.
なお、第２図に示す本考案のバネ組立は、本図のような
円筒状コイルバネのみならず、円錐状コイルバネその他
一般に使用されているバネには全て適用できる。The spring assembly of the present invention shown in FIG. 2 can be applied not only to cylindrical coil springs as shown in this figure, but also to conical coil springs and all other commonly used springs.
またこのバネの係止装置も上記実施例のような係止部６
，７に限らず全て一般に使用される係止装置においても
適用可能であり、前記と同じ効果を得ることができる。Further, this spring locking device is also similar to the locking portion 6 in the above embodiment.
, 7, but can also be applied to any commonly used locking device, and the same effect as described above can be obtained.
