本刊1962年10第期“铣制离合器齿形的几种方法”一文(以下简称原文)和1963年第3期对该文的补充(以下简称周文),给读者带来不少帮助。但两文对铣制离合器齿形时,没有区别离合器的工作角度γ_工和铣刀的工作角度γ_刀。如:加工齿高递减的正梯形和尖齿离合器时,原文导出分度头的倾斜角公式:cos α=tg(90°/z)ctg(γ/2),我们觉得应用它来加工工作角度要求高的离合器是有困难的,因为按原文的推导过程可知,公式中的γ应该是γ_刀,而铣制时已知的是γ_工。
This issue of 1962 tenth period “several methods of milling clutch tooth profile ” (hereinafter referred to as the original) and the third of 1963 to supplement the article (hereinafter referred to as Zhou Wen), to bring readers a lot of help . However, two pairs of milling the clutch tooth shape, there is no difference between the working angle of the clutch γ_ workers and milling cutter angle γ_ knife. Such as: the processing of decreasing tooth trapezoidal and tine clutches, the original derived taper angle formula: cos α = tg (90 ° / z) ctg (γ / 2), we feel that it is used to machine working angle High requirements of the clutch is difficult, because the original deduction process shows that the formula γ should be γ_ knife, and milling is known when γ_ workers.
