目前渦卷式壓縮機大量應用在冷氣空調中，因具有震動小、低噪音等優點，但在壓縮機內部渦卷進行偏心旋轉運動時，軸承表面油膜如承載力不夠時，會使軸承平面因摩擦而受損。過度磨耗會造成壓縮機的消耗功升高，影響效率之外，最終也將使壓縮機損壞。

本研究根據 Sunil S. Kulkarni設定潤滑型態以及尺寸建立幾何網格模型，再使用ANSYS FLUENT進行油膜的CFD模擬，利用Reynolds equation以及有限容積法來計算油膜的壓力分佈。為了探討軸承在不同斜率的傾斜程度以及不同倒角中所造成的影響。本研究建立了不同傾斜角度的模型。以及分別建立外圓上有5mm以及有7mm的倒角之模型。發現傾斜角度越大油膜壓力越大，表示抵抗傾覆力的能力越佳。而倒角越大則油膜壓力越小，底面所受之最大剪力也大幅下降。由結果探討軸承油膜的傾角度以及外圓倒角對於負載壓力、承載力及底面剪力的關係。

lots of scroll compressors are used in air-conditioning because of the advantages small vibration and low noise, but when the scroll compressors working and there will some damage on thrust bearing if the lubrication was not really well.These damage will make scroll compressors need more work and effectiveness lower.

In this study, the geometric grid model and CFD model is established according to Sunil S. Kulkarni to set the dimension and boundary conditions. Use ANSYS FLUENT to simulate the situations.

In the end, we will use this model to investigate the relationship between the inclined plane and the pressure profile of the thrust bearing.
