碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 96 === The gear is an important part for mechanical transmitting and gear shifting It has been widely applied in the machines. The Bevel gear which produced by die forging is not only helping to save raw material, down the cost, but also having high-effect work and good quality of mechanical property. Therefore, the method and technics to make forging gear are becoming a valuable research thema. We are adopting “Deform” software to analyze the cold closed-die forging numerical simulation of Bevel gear.To simulate the Strain-effective and the loading influence with the different modules, teeth and pitch angle of the bevel gear, we also do the cold closed-die forging experiments .To compare experiment result with the Numerical simulation analysis data. Then we can approve the numerical simulation model is correct. In our study, we find that the of the bigger modules and teeth the greater forging and pressing load is, The distribution of the pitch angle influence strain effective , The more small stress effective of the module contain the trend of the increase
