圓弧齒型與X齒型參數自動化

本研究探討螺桿式壓縮機之圓弧齒型與X齒型之型線參數建立，自訂公轉子齒型後由包洛線法於EES人機介面軟體及Matlab輸入產生2D齒型及其共軛齒型，接著以AutoCAD做2D驗證，接著討論理論齒型之干涉問題，由曲線擬合程式說明干涉縮小方式，然後以處理干涉後之2D齒型計算其面積利用係數值，確保設計之齒型能為工業所用，接著，擬合後之2D型線以Creo繪圖軟體繪製為3D齒型，其中運用其參數設計介面，並計算其齒間容積、轉角及壓縮比之關係，且藉由上述結果繪製P-V曲線以便後續計算其功率，本論文中的型線變數皆參數化，未來可依馬達規格功率來設計不同組合之齒型，經由此自動化參數設計流程來符合所需。

This research focuses on the parameter foundation of screw compressor against circular-gear and X gear profile. After the given male rotor is geared, we applied Envelop Method to EES Human-Computer Interface software, input Matlab to generate 2D-gear and Conjugate-gear, and used Autocad to do 2D-test followed by discussion about gear-related questions. We illustrated the interference minimization method with Curve Fitting Program. The deprived 2D-gear after interference was used to calculate the area against parameters. To insure the gear design can be used in industrial world, we transformed 2D into 3D gear, calculated in-between gear volume, corner degree and relationships of compression ratios. Based on the result mentioned above, we drew P-V curve to calculate the power rate for convenience sake. Gear variables were parameterized in this thesis. In the future, gear adjustment based on motor standard power is available through automated parameter design process to meet various demands.
