摘要

本研究之目的在於提出凸輪控制式行星齒輪系機械效率之最佳化方法，以提升其機械效率。首先，進行CCPGT之運動靜力分析，以建立各機件間之作用力、搖撼力、凸輪壓力角、摩擦力矩、摩擦損失功率以及機械效率之數學模式。接著，以機械效率為目標函數，進行最佳化的設計，並以三實例進行最佳化設計，以求得最佳之尺寸參數與輸入轉速曲線，達到提升機械效率之目的。由結果顯示，所提出之最佳化方法，可有效提高機構之機械效率。

This study aims to propose an optimal approach for the mechanical efficiency of cam-controlled planetary gear trains such that the efficiency can be increased. First, the kinetostatic analysis is performed to establish equations of the force between parts, the shaking force, the pressure angle, the friction torque, the friction power, and as well as the mechanical efficiency. Then, kinematic sizes and variable input speed curves are specified as the design variables, and the mechanical efficiency is set as the objective function for optimization. Furthermore, three design examples are given for illustrating the process of the optimization. The results show that the proposed optimal approach can significantly improve the mechanical efficiency of the trains.
