本文提出擺線減速機之擺線輪斜角齒形設計，其目的在於解決減速機振動的問題，以及提昇減速機工作效率，本文主要是以動態模擬分析與結構分析，比較新型斜角設計的擺線輪齒廓與傳統的擺線輪優劣。利用Solid Works來建立擺線輪齒形，以驗證本文數學模式所建立之曲線無誤。先以COSMOSMotion與COSMOSWorks對三個減速增矩的主要零件做動態模擬分析與結構分析，求出擺線輪與偏心軸的角加速度與動量變化曲線，以及結構應力變化情形，接著根據主要減速增矩零件所分析的結果，進行擺線減速機整體動態模擬分析與結構分析，瞭解擺線輪在齒形上的改變，對減速機運轉的振動情形、結構應力變化以及工作效率有何影響。結果發現斜角齒形α3.5°能夠改善擺線減速機的震動情況，提高輸出扭矩平均值。透過本文對於擺線減速機在齒形設計上之研究，有助於提供學術界與產業界之參考。

This paper presented is design of the cycloid drives gear tooth profile. This goal is in to solve the question of the speed reduce with the vibration and make the work effectively. The discussion about Dynamic simulation analysis and structure analysis using the design of the cycloid drives gear tooth profile. From the analysis compare their differences: new gear tooth profile and skew angle design of the traditional cycloid gear. Using the Solid Works to build a new project of gear tooth profile and prove the curve of mathematic model is correct. At first, using the COSMOSMotion and the COSMOSWorks corresponding three major parts of the manufactured component speed reduce increase moment with dynamic simulation analysis and structure analysis, obtained angular velocity with movement variation curve and structure stress variation. And then, run an integral whole analysis. Then observes the vibration of the gear tooth during the operations and analyzes the influence of the structure stress variation. The gear tooth profile α3.5° is able to improve the vibration of cycloid drives gear tooth profile and the moment average value.The results found in the current study will shed some lights on the research of cycloid drives gear tooth profile for the academia and industry.
