本発明は、冷凍サイクルに用いられる回転式圧
縮機に関し、特にその振動低減装置に係わる。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rotary compressor used in a refrigeration cycle, and particularly to a vibration reduction device thereof.
従来例の構成とその問題点
従来のこの種回転式圧縮機は、第３図に示すよ

かつた。フライホイールを設置して振動の転減を
行なう構成も考えられていた。Configuration of conventional example and its problems As shown in Fig. 3, in a conventional rotary compressor of this type, the rotor a, crankshaft b, and piston c, which are rotating system parts, are located within the radius of rotor b. Therefore, it is not easy to increase the moment of inertia of the rotating system, and the effect of reducing vibration cannot be obtained. A configuration in which a flywheel was installed to reduce vibrations was also considered.

大するなどの欠点があつた。 Further, in order to balance the eccentricity of the crankshaft b of the rotating system, balance weights are attached above and below the rotor a of the rotating system, but as the eccentricity of the crankshaft b increases, the rotation The upper balance weight A 1 and lower balance weight A 2 attached to the rotor also become larger, and in some cases, the design becomes unable to achieve perfect balance due to the limited distance between the rotor end face and the upper bearing d. It had In particular, when a flywheel is attached, a space in the height direction corresponding to the thickness of the lower balance weight and the flywheel is required, resulting in disadvantages such as an increase in the height of the compressor.

る。Structure of the Invention In order to achieve this object, the present invention installs a flat flywheel in a rotating system to increase the moment of inertia. Furthermore, a notch corresponding to the lower balance weight is provided in the flywheel to provide a compact balance weight structure.
実施例の説明
以下本発明の一実施例を添付図面の第１図、第
２図により説明する。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.
第１図において、１は密閉容器、２は前記密閉
容器１内に固定された電動機固定子、３は回転
子、４は前記回転子３により回転されるクランク

すように前記平板６に設けられている切欠き６ａ
は、前記クランク軸４の偏心部４ａの偏心方向と
同一方向の外周にある。 In FIG. 1, 1 is a sealed container, 2 is a motor stator fixed in the sealed container 1, 3 is a rotor, 4 is a crankshaft rotated by the rotor 3, and 5 is a crankshaft of the crankshaft 4. A piston that compresses refrigerant using axial force. 6 is a flat plate fixed to the rotor 3 with bolts 7. Further, as shown in FIG. 2, a notch 6a provided in the flat plate 6
is located on the outer periphery in the same direction as the eccentric direction of the eccentric portion 4a of the crankshaft 4.

転系を構成している回転子３、クランク軸４、ピ
ストン５、平板６による慣性モーメントが、従来
の回転子３、クランク軸４よりなる回転系よりも
平板６による慣性モーメント分が増加するため、
圧縮機の振動を低減する効果が得られる。 In the above configuration, when the compressor is operated, the moment of inertia due to the rotor 3, crankshaft 4, piston 5, and flat plate 6 that constitute the rotating system is different from that of the conventional rotating system consisting of the rotor 3 and crankshaft 4. Since the moment of inertia due to the flat plate 6 increases,
The effect of reducing compressor vibration can be obtained.
またクランク軸偏心部４ａに相当する下バラン
スウエイト分を、平板の外側の切欠き６ａにより
代用しているため、スペース的にも内周に設ける
より小さなものとなり、従来のように下バランス
ウエイトを設ける必要がないため、高さ方向のス
ペースも縮小しコンパクトな圧縮機の設計が可能
となる利点が得られる。 In addition, since the lower balance weight corresponding to the eccentric part 4a of the crankshaft is replaced by the notch 6a on the outside of the flat plate, the space is smaller than that provided on the inner periphery, and the lower balance weight can be replaced as in the conventional case. Since there is no need to provide a compressor, the space in the height direction can be reduced and a compact compressor can be designed.

効果を奏する。Effects of the Invention As is clear from the above explanation, the present invention can reduce the vibration of the compressor by newly installing a flat plate in the rotation system of the rotary compressor and increasing the moment of inertia. In addition, since the outer periphery of the flat plate has a notch in the same direction as the eccentric direction of the crankshaft, there is no need to install a new balance weight, resulting in a compact structure in terms of space, especially in the height direction. It has the effect of
