我厂常遇到键槽与齿形间有各种相位要求的齿轮件，显然，在一般插床上若仅按传统的划线加工方法是难以保证的。为此，我厂摸索出了一套行之有效的加工方法。一、找正方法通过找正，使所要加工的键槽处于与齿形间有正确相位的位置。为此，除了正常划线初定位置外，还设计了如图? I often encounter plant with a key slot and tooth profile between the various phase requirements of the gear, it is clear that if only in the general slot machine according to the traditional scribing method is difficult to guarantee. To this end, I plant worked out a set of effective processing methods. First, find ways to correct, so that the keyway to be processed in the correct phase with the tooth position between the positions. To this end, in addition to the initial location of the normal crossed, but also designed as shown?
