擺線齒輪減速器力量分析與有限元素模擬

Abstract

擺線齒輪減速器使用在精密機械的傳動上已有一段很長的時間。近年來，擺線齒輪減速器已朝向高扭力密度之方向發展，故對於擺線齒輪減速器元件之受力分析，需要有更深的了解與探討。本文首先針對文獻中擺線齒輪減速器力量分析的方法做一介紹，接著使用材料力學提出一簡單支撐梁之力量假設，求解一內擺線齒輪減速器之受力，並與軟體模擬的結果以及文獻所使用方法之結果做一比較，便於後續分析者能夠選取力量求解方法做分析。本文亦藉由CAD與有限元素模擬軟體，建立模擬的流程，提供模擬時須注意之模擬細節，以得到較佳之收斂模擬結果。

Cycloidal reducers have been applied for the transmission mechanism in precision machine for a long time. Recently, the development of cycloid gear reducers has been focused on the high torque density design. In light of this trend, it is necessary to understand and explore the gear reducer in the force/torque aspect. This thesis first reviewed the methods of force analysis for cycloid gear reducers. Then, a method based upon the superposition method is proposed for the analysis of the contact force between cycloid lobe and pin. The results are compared with the results of FEM analysis as well as traditional force analysis method. This paper also presents the detail simulation process using the FEM software. The process shows that convergent results can be achieved by using the parameters selected in the thesis.
