当加工精度要求不高的直齿锥齿轮时,其盘铣刀的齿形可用如下的作图法求得。此法作图简单,而且铣刀齿形样板的制造也较方便,尤其对缺乏曲线磨床的中、小型工厂更为适用。一、作图法的依据盘铣刀的齿形是锥齿轮大端当量齿轮的齿形,宽窄是按小端当量齿轮齿间的宽窄来制造的。如图1所示,用盘铣刀加工齿轮毛坯时,铣刀只能铣出齿坯上 When the machining accuracy is not demanding straight bevel gear, the disc cutter tooth profile can be obtained using the following mapping method. This method is easy to draw, and the manufacture of cutter tooth profile is more convenient, especially for medium and small factories which lack curve grinding machine. First, the method of drawing method According to the milling cutter tooth profile bevel gear large tooth equivalent gear, width is based on the width of the small end equivalent gear teeth to create. As shown in Fig. 1, when milling the gear blank with the disk cutter, the cutter can only mill the gear blank
