Abstract | To provide a hermetic type compressor capable of restraining increase of a sliding loss.SOLUTION: A compression element 106 of a hermetic type compressor 100 has:a crank shaft 134 having a main shaft part 155 and an eccentric shaft part 156; a block 123 having a cylindrical cylinder bore 124; and a piston 125 coupled with the eccentric shaft part via a connection rod 158, and provided movably forward and backward in the cylinder bore. A first frame 136 having a first bearing hole 141, and journaling a first portion 152 of the main shaft part inserted in the first bearing hole on an inner periphery, a second frame 138 having a second bearing hole 150, journaling a second portion 154 provided on a side opposite to the eccentric shaft part across the first portion at the main shaft part and inserted in the second bearing hole on an inner periphery, and arranged to sandwich an electric element 104 between it and the second frame, and a first connection part 137 and a second connection part 139 connected to the first frame and the second frame are integrally formed on the block.SELECTED DRAWING: Figure 1
【課題】摺動損失の増加を抑制できる密閉型圧縮機を提供する。【解決手段】密閉型圧縮機100の圧縮要素106は、主軸部155及び偏心軸部156を有するクランクシャフト134と、筒形状のシリンダボア124を有するブロック123と、偏心軸部にコンロッド158を介して連結され、且つ、シリンダボア内に往復自在に設けられたピストン125とを有し、ブロックには、第1軸受孔141を有し、且つ、第1軸受孔に挿通された主軸部の第1部分152を内周面で軸支する第1フレーム136と、第2軸受孔150を有し、主軸部において第1部分を挟んで偏心軸部側と反対側に設けられていると共に第2軸受孔に挿通された第2部分154を内周面で軸支し、且つ、第1フレームとの間に電動要素104を挟むように配置された第2フレーム138と、第1フレーム及び第2フレームに接続された第1接続部137及び第2接続部139とが一体的に形成されている。【選択図】図1 |
