摘要

本研究之目的在於進行凸輪控制式行星齒輪系之系統化設計與分析，包括構造合成、運動與幾何設計、動力分析、及機械效率實驗等。首先，研究變轉速機構之特性，訂定構造與運動上之設計需求及限制，然後，依據創意性設計方法，以產生新型機構目錄，並以ADAMS軟體進行運動模擬，驗證新型機構之可行性。接著，提出一套運動設計流程，以進行輸出轉速設計。然後，進行運動靜力分析，探討各機件間之作用力、摩擦力、及摩擦功率，以建立力量分析與機械功率分析之數學模式。最後，並建立一套測量機械效率之實驗系統，以做為理論對照之依據。由結果顯示，新型可產生較複雜之變轉速輸出，且所提出之運動設計流程為正確可行。除此之外，應用動力分析所推導之公式，可計算出各機件之作用力、摩擦功率、及機械效率等。

This paper aims to perform the design and analysis of cam-controlled planetary gear trains, including structural synthesis, motion and geometrical design, dynamic analysis, design example, and mechanical efficiency testing. Firstly, the design requirements and design constraints are summarized according to the kinematics characteristics of cam-controlled planetary gear trains. Then, the graphs are specialized, and the atlas of feasible specialized graphs is generated. Following by some particularization process, atlas of new designs could be obtained. An example illustrated by the feasibility of new designs is also simulated and verified by performing ADAMS. Next, the output RPM of CCPGT is designed by proposing an motional-design process, and verified by performing ADAMS. Then the applied forces, friction forces, and friction efficiencies between each part are discussed, to induce the mathematical model of CCPGT dynamic analysis and mechanical efficiency. Finally, an experimental system is built that could validate CCPGT efficiency with theoretical model. The result shows that new designs can effectively produce a more wide range of non-uniform motion. In addition, the motion and geometrical design process is correct and feasible. Furthermore, the friction forces between each part, mechanical efficiency of CCPGT, and location and mass of equivalent block, can be estimated by the equation deduced from dynamical analysis.
