這項課題。齒頂導角方 降低齒輪振動噪音，
並且對於螺旋齒輪對之整體效能並無明顯的影響。
5.2 未來展望
本研究之齒輪動態分析，得到了組合誤差、隆齒量、齒頂修整與過切對於螺 旋齒輪對動態特性的影響。但數值結果之驗證則仍需進一步之研究或實驗量測來 確認之。另外對於加工誤差包含齒形誤差、導程誤差、節距誤差及偏心誤差等，
組合誤差則分為軸中心距誤差、軸平行度誤差、軸偏心誤差，以及受外力造成之 動態彈性變形誤差等，上述各種誤差對於螺旋齒輪對動態特性的影響，或經由更 明確的主動齒輪與被動齒輪之定義，來獲得更佳的傳動誤差值等，則仍是後續值 得研究的課題。
而以 FEM 之近似連體模式齒輪動態分析，為提高建模準確度，其網格模式 越精细越準確，但是網格數目會增加，也會造成運算時間成級數延長。如何细化 網格模式以提高準確度而又不會增加運算時間，為提高齒輪動態分析的研究成效 之關鍵；另外，動態模擬分析之建模元素皆為直邊元素，對於非直邊曲線是用细 化網
法可以避免齒頂與齒腹產生干涉以及
格來提高分析準確率；因此，建立非直邊網格元素之齒輪動態分析，以提高 數值分析效率，都是未來值得探討的方向。
