HERMETIC ROTARY COMPRESSOR

To provide a hermetic rotary compressor and a refrigerator, in which an appropriate amount of lubrication oil is supplied to rolling bearing portions and increase in friction loss due to uneven contact with respective sliding portions is reduced.SOLUTION: A hermetic rotary compressor 100 of the present invention comprises: a closed container 1; a compression mechanism section 4 comprising a roller 9 that rotates eccentrically in a cylinder 8, a crankshaft 3 that has an eccentric portion 3a for rocking the roller 9, an upper shaft 3b and a lower shaft 3c, and upper and lower radial bearings 5, 6 for supporting the crankshaft 3; a suction flow passage; and a discharge flow passage. The hermetic rotary compressor has a thrust rolling bearing 21 above the upper radial bearing 5. The upper shaft 3b has, on its side surface, a communication hole 3g for connecting the inside and outside of the crankshaft 3. The upper shaft 3b has, below the center position of the communication hole 3g, a recess 3i having a shape recessed from the outer peripheral surface of the upper shaft 3b, and a bearing sliding portion 3b1 forming the outer peripheral surface of the upper shaft 3b.SELECTED DRAWING: Figure 1 【課題】転がり軸受部に適切な量の潤滑油を供給すると共に，各摺動部への片当たりによる摩擦損失増大を低減する密閉型ロータリ圧縮機および冷蔵庫を提供する。【解決手段】本発明の密閉型ロータリ圧縮機１００は、密閉容器１と、シリンダ８内で偏心回転するローラ９と、ローラ９を揺動させる偏心部３ａおよび上軸３ｂおよび下軸３ｃを有するクランク軸３と、クランク軸３を支持する上・下ラジアル軸受５，６を備える圧縮機構部４と、吸入流路と、吐出流路とを備え、上ラジアル軸受５上方にスラスト転がり軸受２１を有し，上軸３ｂにはクランク軸３内外をつなぐ連通穴３ｇを側面に有し，上軸３ｂは，連通穴３ｇの中心位置よりも下方に，上軸３ｂの外周面から凹んだ形状の凹部３ｉと上軸３ｂの外周面を形成する軸受摺動部３ｂ１とを有している。【選択図】図１
