摘要

齒輪減速機於現今應用廣泛，齒輪減速機主要用途為透過齒輪傳動將馬達的轉速降低至所需之轉速，並在儘可能減少功率損失的情況下得到較大輸出扭矩，而傳統重工業界的齒輪減速機多半較為大型，且傳遞功率及負載較大，並有不易更換零件、停機檢修及負載量測等缺點。故本文應用商用機械零件設計軟體KISSsoft及其機械系統設計模組KISSsys建立一組軋鋼四級齒輪減速機的分析模型及程序，以快速地獲得各齒輪危險截面安全係數、齒輪對之齒面接觸及齒根彎曲強度安全係數、及各軸承之使用壽命；此外，為了取得較佳之齒面接觸安全係數、齒根彎曲安全係數、傳動誤差與齒面負載分佈係數之值，將齒輪對設計參數透過均勻實驗建立目標函數之RBF代理模型，接著利用RBF代理模型進行齒輪對設計參數最佳化設計，最後，將齒輪對最佳化之設計參數代入KISSsoft齒輪減速機模型分析並與齒輪對設計參數最佳化前進行比較。針對齒輪強度不足之處給予設計改良及建議方案，以供業界作為齒輪減速機開發後用以評估及檢視設計強度及傳動性能之參考依據。

Nowadays, gear reducers have already been widely applied to all kinds of industries. The main purpose gear reducer is to reduce the rotational speed of motor to the speed gear reducers need and to raise the output torque with as low a loss of power as possible. Transferring high power and enduring large loading, the gear reducers used in traditional heavy industry are usually huge, for which replacing parts, overhauling, and measure loading data are difficult. The research subject of this thesis is a four-stage gear reducer applied in steel rolling. For the gear reducer, in the paper build a set of analytic model and procedure that can calculate the gear fatique safety factor, the flank safety factor and root safety factor of gear pairs, and the life time of bearing, by KISSsys a mechanical system designing model of KISSsoft a mechanical-component-designing business software. Furthermore, in order to obtain better values of flank safety factor, root safety factor, transmission error and face load coefficient, in the paper build the RBF surrogate models of target functions based on the data of uniform experiments. Then, optimization technique is applied to search optimal solutions to design parameters of the gear reducer. At last, in the paper put the optimal solutions of design parameters to the analytic model of gear reducer and propose an improved version of gear reducer. The improved design of gear reducer can be reference to industry in evaluating and examining strength and transmission characteristics of four stage gear reducer designing applied in steel rolling in the future.
