在齿轮精加工方法中,由于剃齿效率高、成本低,且对齿形、齿向、径向跳动有一定的改善效果,因而被广泛采用。但剃齿工艺也存在致命的缺点:如果用目前市场上供应的标准剃齿刀,剃出的齿形在分度圆附近产生不同程度的中凹现象。随着齿数的减少,中凹现象越趋严重,影响齿轮的精度,见表1.这个问题是级套级贯彻齿 In the gear finishing method, it is widely used because of its high efficiency, low cost, and some improvement on tooth profile, tooth direction and radial runout. However, the shaving process also has a fatal disadvantage: if the shaving cutter is used on the market today, the shaved tooth forms a different degree of concavity near the pitch circle. With the reduction of the number of teeth, the more serious depression phenomenon, affecting the accuracy of the gear, see Table 1. This issue is the level of implementation of gear teeth
