Summary:	齒輪是機械傳動與變速的重要零件，在各類機械中的運用相當廣泛。以鍛造技術生產傘形齒輪具有節省材料、低成本、高效率、機械性質佳等優點，故傘齒輪鍛壓方法與技術的發展已越來越受重視。本論文採用DEFORM軟體對傘型齒輪進行冷精密鍛造數值模擬分析。以探討不同齒輪模數、齒數、與齒圓錐角分別對工件等效應變、等效應力與成形負荷的影響並進行傘齒輪冷精鍛試驗，以驗證數值模擬分析的準確性。研究結果發現齒數與模數越大則鍛壓負荷越大，節圓錐角影響等效應變最大值的分佈，而模數越小等效應力有增大的趨勢。 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
