Summary: | PROBLEM TO BE SOLVED: To provide a scroll type fluid machine for solving the problem that the temperature rises in the individual portions of a turning scroll part due to the compression heat accompanying a rotation compression operation and the exothermic heat of a bearing, so that the lubrication deteriorates due to the deterioration of grease filled in the bearing part.SOLUTION: A grease reservoir for reserving grease for a turning bearing 29 is disposed to protrude over a back plate 12 of a turning scroll 8 and over a passage of a cooling fluid for cooling the turning scroll 8. As a result, the reliably of the turning bearing 29 can be improved by suppressing the thermal deterioration of the grease in the grease reservoir.
【課題】スクロール式流体機械において、旋回スクロール部は回転圧縮動作に伴う圧縮熱および軸受の発熱により各部の温度上昇が起こり、軸受部に封入されたグリースの劣化による潤滑性の低下する。これらの問題点を解決するスクロール式流体機械を提供する。【解決手段】旋回軸受29のためのグリースを貯留するグリース溜りを、軸受29と連通し、旋回スクロール8の背面プレート12上であって、旋回スクロール8を冷却する冷却流体の流路上に突出して設けた。これにより、グリース溜り内のグリースの熱劣化を抑制し、旋回軸受29の信頼性を向上できる。【選択図】図1 |
