用插齿刀加工规定参数的齿轮时,首先应校验已有的旧插齿刀是否能够加工,如能加工,就可省去新插齿刀的设计和制造.插齿刀除了模数、分度圆压力角、齿高系数应和被加工齿轮的参数一致外,还应校验加工齿轮时是否发生根切和顶切以及校验被加工齿轮和相配齿轮啮合转动时是否发生过渡曲线干涉.只有经过以上校验后,方能确定该旧插齿刀是否合乎加工要求,以上的具体校验计算都涉及到旧插齿刀的变位系数.只有测出使用的旧插齿刀前端面上变位系数x_0 ,才有可能对旧插齿刀进行以上的校验计算,因此,测量旧插齿刀的变位系数十分重要.由于插齿刀是有前、后角的齿轮,因此其变位系数的测量与齿轮的变位系数测量是有区别的.如按变位齿轮的测量方法测量插齿刀就会出现较大的误差,影响插齿刀的
When using the gear cutter to process the gear with the specified parameters, it is first necessary to verify whether the existing gear shaper cutter can be processed, and if it is machined, the design and manufacture of a new gear shaper cutter can be omitted. The indexing circle pressure angle and the tooth height coefficient should be consistent with the parameters of the gear to be machined. It should also check whether the undercutting and topcutting occur when machining the gear, and whether the transitional curve interference occurs when the gear to be machined and the matched gear rotate. Only after the above verification can we determine whether the old gear shaper meets the machining requirements and the above specific calculation involves the displacement factor of the old gear shaper.Only the used gear shaper front face The upper displacement coefficient x_0, it is possible to carry out the above calculation of the old gear shaper cutter, so it is very important to measure the displacement factor of the old gear shaper cutter, because the gear shaper cutter is a front and rear angle gear, so its Displacement coefficient measurement and gear displacement coefficient measurement is different.As measured by the displacement gear measuring gear shaper will appear larger errors affect the gear shaper
