我们利用微型电子计算机,根据已知的传动比。及理论误差D_i等数据,按照一定程序输入计算机后,可直接打印或显示出四个挂轮的齿数z_1、z_2、z_3和z_4。与其他方法相比,用微机选配机床挂轮具有计算速度快、精度高等特点,现介绍如下。一、计算方法 (1)将i化成一些近似分数,并选取满足精度的那些近似分数。设i<1,i=A/B(式中A、B为自然数)。一般情况下,齿数z的值为20～127,且z_1、z_2、z_3和z_4是互不相等的自然数。由此可知:B的最大值B_atax=127×126=16002:A的最小值A_min=420(=20×
We use miniature computers, based on known gear ratios. And theoretical error D_i and other data, according to a certain program input into the computer, you can directly print or display the number of teeth of the four hangers z_1, z_2, z_3 and z_4. Compared with other methods, with a computer-based machine with the calculation of the wheel speed, high precision, are described below. First, the calculation method (1) i into some approximate scores, and select those that meet the accuracy of those approximate scores. Let i <1, i = A / B (where A and B are natural numbers). In general, the number of teeth z is 20 to 127, and z_1, z_2, z_3, and z_4 are natural numbers that are not equal to each other. It can be seen: B maximum B_atax = 127 × 126 = 16002: A minimum A_min = 420 (= 20 ×
