用于高速切削的机械滑台,在一些厂家生产后,遇到的一个突出问题,就是双联齿轮的上下联有一个齿必须严格对齐的问题。双联齿轮(图1)的主要参数如下: m=1.75,a=20°,z_1=20,z_2=17,精度等级8-7-7DC,L_1=13.406_(-0.115)~(-0.075),L_2=8.166_(-0.115)~(-0.075) 技术条件要求双联齿轮的上下联有一个齿必须严格对齐,允差为0.05mm,在Y54插齿机上加工。现在经过我们在操作方法上作了改进后,已经满 For high-speed cutting machine slide, produced in some manufacturers, one of the outstanding problems encountered is that the double gear has a tooth on the upper and lower teeth must be strictly aligned. The main parameters of the double gear (Figure 1) are as follows: m = 1.75, a = 20 °, z_1 = 20, z_2 = 17, accuracy level 8-7-7DC, L_1 = 13.406 _ (-0.1150) , L_2 = 8.166 _ (- 0.115) ~ (-0.075) Technical Requirements Double teeth of the upper and lower teeth of a gear must be strictly aligned with a tolerance of 0.05mm, machined on a Y54 gear shaper. Now after we made improvements in the operation method, it is full
