本刊1962年第10期“铣制离合器齿形的几种方法”一文中,介绍了加工直齿、梯形齿、尖齿和锯齿离合器齿形的方法,以及计算分度头仰角的公式和表格,给读者带来了很大的帮助和方便。但对实际操作者来说,这些资料还是不够的,现作补充如下。一、铣刀宽度的选择(1)加工直齿离合器时:铣刀若选择得太宽(用立铣刀时为铣刀的直径),则会切到相邻的一个齿;若选择得太窄,则会切剩一小部分金属,必须把分度头和工件进行调整后再将它切去,以致影响生产效率。因此,铣刀宽度B应按下面方法进行选择:从图1可知,铣刀宽度应小于或等于b,并应尽可能大于
In this article, “The Several Methods of Clutch Tooth Profile Milling”, 1962, introduced the method of machining tooth profiles of straight, trapezoidal, serrated and serrated clutches, as well as the formulas and tables for calculating the elevation of the indexing head , To the reader has brought great help and convenience. However, for the actual operator, the information is still not sufficient. The following is added below. First, the choice of cutter width (1) processing straight-tooth clutch: If the cutter is too wide selection (with the cutter when the milling cutter diameter), it will cut to an adjacent tooth; if too Narrow, it will cut a small part of the metal, you must adjust the indexing head and the workpiece and then cut it, which affects the production efficiency. Therefore, the cutter width B should be selected as follows: As can be seen from Figure 1, the cutter width should be less than or equal to b, and should be as large as possible
