Summary: | 碩士 === 大葉大學 === 機械工程研究所 === 87 === The object of this study is to analyze and design the transmission mechanism of two-wheel vehicles. This study chooses a planetary gear train with two degrees of freedom as the transmission mechanism. And its design method is the creative design of mechanical devices.
First, by designing the transmission mechanisms of six and seven members planetary gear trains, this study finds out and witnesses to the enacting reasons of design requirements and constraints of the creative design of mechanical devices.
Then, this study is going to bring out a systematic design method for planetary gear trains──Creative and synthetic design of planetary gear trains. From the design process of the transmission mechanism of eight members planetary gear train, this study accounts for the compactness and correctness of this design method.
In addition, this study establishes the complete atlas of mechanism sketches of the transmission mechanisms of six, seven and eight members planetary gear trains. And it also researches and analyzes a SACHS’ transmission mechanism with five speeds for bicycles.
Last, to establish foundations of posterior studies, this study brings out some ideas about doing concrete designs of new transmission mechanisms.
