Summary: | PROBLEM TO BE SOLVED: To provide a reciprocating hermetic refrigerant compressor which can reduce both of the vibration and the size.SOLUTION: A hermetic refrigerant compressor 10A includes an electric element 20A and a compression element 30 stored in a hermetic container 11, and the compression element 30 has a cylinder 32 and a piston 33 reciprocating in the cylinder 32. The electric element 20A includes a stator 21A, and a rotor 22A arranged in such a manner that a lower surface thereof faces an oil surface of lubricating oil 13. A diameter of the rotor 22A is larger than its length in a rotation axis direction. Further, at least one balance hole for adjusting load balance in rotation, for example, a balance through hole 24A, is formed in an iron core of the rotor 22A.SELECTED DRAWING: Figure 1
【課題】 低振動化および小型化の双方を実現することが可能な、レシプロ式の密閉型冷媒圧縮機を提供する。【解決手段】 密閉型冷媒圧縮機10Aは、密閉容器11内に収容される電動要素20Aおよび圧縮要素30を備え、圧縮要素30は、シリンダ32とシリンダ32内で往復運動するピストン33とを備える。電動要素20Aは、固定子21Aとその下面が潤滑油13の油面に対向するように設けられる回転子22Aとを備える。当該回転子22Aは、その直径が回転軸方向の長さよりも大きく構成されている。さらに、回転子22Aの鉄心には、回転時の荷重バランスを調整する少なくとも1つのバランス穴、例えばバランス貫通孔24Aが設けられている。【選択図】 図1 |
