摘要


本文是根據齒輪嚙合原理以及微分幾何探討在切削加工戟齒輪時之共軛條件。一般來說,小輪與大輪由於壓力角、螺旋角、齒面形狀不同,會分別選用不同的刀具,這也讓戟齒輪大小輪的加工需要多道步驟以及加工機台,這會讓加工時間及成本大幅增加,因此本文除了介紹一般大小輪的加工設計方法外,藉由改變小輪切齒計算方式達到不使用等距共軛面原理即可改變小輪刀具壓力角,並探討大輪與小輪共用刀具之小輪機械設定與共用刀盤時小輪需修正的項目,最後由曲率修正來改善大小輪齒面嚙合接觸區不良的問題。

Based on the theory of gearing and differential, this thesis introduces a new method of hypoid gear manufacturing process. In the past, the point radius difference between the inside blade and outside blade of the pinion cutter may not be fit in the same head cutter. Therefore, both side of pinion tooth have to cut in different CNC hypoid generator with different head cutter. By using pinion curvature and cutter pressure angle adjustment, the point radius of the inside blade and outside blade can be fit in the same cutter head.
