摘要

齒輪為最常用的機械元件之一，其中又以蝸線傘齒輪和戟齒輪具有高效率、高強度及低噪音的特性，而被廣泛的應用在汽車產業的傳動系統和工業用減速機上。本文中介紹一傘齒輪製程優化技術，包含「壓淬熱處理」、「齒輪智慧製造閉迴路」及「齒輪切削優化」，能有效提升加工精度及效率。其中「齒輪智慧製造閉迴路」為先建立出一理想齒面，加工後量測齒輪並與理想齒面比較誤差，再經由演算法對加工機之機械設定進行補正，進而提升齒面的加工精度；「齒輪切削優化」則是透過調整切削時的進給、切削速率，來平均切削時的切削力變化，達到提升加工效率及減少刀具磨耗的效果。

In mechanical industry, gear is one of the most commonly mechanical components. Among them, because of the characteristics of high efficiency, high strength and low noise, spiral bevel and hypoid gears are widely used in the transmission system of the automobile industry and gear reducers. This article introduces the process optimization of spiral bevel gear manufacturing, which include ＂Pressure quenching＂, ＂Closed-loop manufacturing technology of spiral bevel gear＂ and ＂Spiral bevel gear cutting force and cutting parameter optimizations＂ systems, can effectively improve machining accuracy and efficiency. In ＂Closed-loop manufacturing technology of spiral bevel gear＂, whose usually proceeds as follows: first, construct a theoretical flank coordinates, and then measure the gear flank after machining and calculate the deviation based on the theoretical flank; second, the machine setting corrections to minimize real surface deviations are calculated using linear regression; In ＂Spiral bevel gear cutting force and cutting parameter optimizations＂, which can achieve the effect of improving efficiency and reducing tool wear by adjusting the feed and cutting rate during machining to average the cutting force.
