一般傳動機械如:汽車、機車...等,主要動力來源都是以齒輪傳動為主,本文是探討機車傳動的齒輪,齒輪傳動會因為齒型設計不當、裝配誤差、結構共振、加工精度...等,都可能產生傳動元件的噪音,除了以上的因素齒輪的齒形參數也扮演著極重要的角色,不一樣的參數變化也會影響到齒輪的傳動。
本論文研究內容是齒形幾何參數改變對於傳動穩定度及接觸應力的影響,藉著CAD(Computer Aided Design)電腦輔助設計軟體 Solidworks 建立齒輪模型,在將其模型匯入CAE(Computer Aided Engineering)電腦輔助分析軟體 ANSYS進行暫態分析(transient dynamic analysis),分析完的結果在匯出經由Matlab來做後端訊號處理,並且利用以傅立葉轉換(Fourier Transform)為基礎的快速傅立葉轉換(Fast Fourier Transform) 做為分析方法,然後針對暫態分析中的作用力來進行時域(time domain) 、頻域(frequency domain) 來做分析及比較,再來判別不同的齒形幾何參數,對於齒輪的齒根應力、傳動穩定上有甚麼影響。最後可以歸納出齒形參數改變的影響,提供一個齒形設計上的分析檢驗流程。
For general transmission machinery such as cars, motorcycles etc., the main power sources are all generated through transmission of gears. In this paper, the gear of the transmission of a motorcycle is explored. Due to several reasons, for example: improper tooth type design, error of assembly, structural resonance, and machining in accuracy, the transmission gears may produce noise. Also, the gear parameters play important roles of the gear transmission.

The focus of this research is the effects of gear geometric parameter on transmission stability and contact stress. By using the CAD (Computer Aided Design) software called Solidworks, gears are modeled. Then the models are imported into CAE (Computer Aided Engineering) software ANSYS to analyze transient dynamic analysis. The results of the analysis are exported to Matlab to do the digital signal process. Finally, the responses of the system are frequency analyzed and also are analyzed in time domain. It is found out that the influence of contact stress and transmission stability is strongly influenced by the gear parameter. It is concluded that a gear design analysis process has been developed by changing the gear design parameter.
