用滚刀滚切齿轮是最常见的且效率较高的加工方法,因此加工后的精度必然受到多方面的关注。例如滚刀是否要对中这个问题,至今仍颇多争论。文献[1]等资料认为,如果滚刀的一个刀齿或刀槽的对称线不通过齿坯中心的话,将会造成被加工齿轮齿形的倾斜、不对称。迄今为止,仍有许多厂家在滚齿过程中进行对中操作,甚至为此设计专用的对刀架。 Hob cut gear hobbing is the most common and efficient processing methods, so the accuracy of the processing is bound to be multi-faceted. For example, whether hobbing should be centered on this issue is still a lot of controversy. Literature [1] and other data that, if a cutter hob or knife groove symmetry line does not pass through the center of the gear, it will cause the gear tooth profile is tilted, asymmetric. So far, there are still many manufacturers in the hobbing process centering operation, and even designed for this purpose dedicated turret.
