摘要

雙蝸桿傳動多以交錯軸的方式進行，目前鮮少有相關文獻探討。本文依據蝸桿之幾何外形與切削方式，先利用座標轉換的方法分別建立蝸桿之齒面數學方程式。?探討交錯軸雙蝸桿之間的齒面接觸，依據上述建立之齒面數學模式，利用等高線法來研究雙蝸桿齒面之接觸情形，並探討交錯軸蝸桿搭配時之齒面接觸情形。最後並以有限元素分析研究其接觸應力，其結果亦可用於驗證等高線法之正確與否。本文亦針對交錯軸雙蝸桿傳動之傳動效率進行探討。

The transmission of twin-worms can be set in crossed axes. Now there are few studies in literature. In this thesis, the mathematical models of different types of worm are set up using the coordinate transformation method. The contour method is applied to investigate the contact pattern of the twin-worms in crossed axes. The effects of different design parameters on the contact pattern are then studied. The finite element method is then used to study the contact stress and strain between the two worms. The results can also be used to verify the contact condition predicted by the contour method. The efficiency of the twin-worms drive set in crossed axes is also studied.
