一、问题的提起据根有关文献介绍车、铣床主轴的最大扭矩计算公式 M=974N/(n_i)η(kg-m)[N:主电机功率(KW);n_i:主轴计算转速(r/min),等公比传动通常为主轴从最低转速算起第一个三分之一转速范围内的最高一级转速,混合公比或无级调速 n_i=n_(min)((n_(max))/(n_(min)))~(0.3),n_(min)为主轴最低转速,n_(max)为主轴最高转速;η:传动效率。],对单速主电机的机床可以很方便地进行计算。 First, the problem filed According to the root of the literature about the literature, the maximum torque of the spindle milling machine formula M = 974N / (n_i) η (kg-m) [N: main motor power (KW); n_i: spindle calculated speed (r / min), etc. Equal drive is usually the highest speed of the spindle in the first one-third speed range from the lowest speed, mixed common or stepless speed regulation n_i = n_ (min) ((n_ (max )) / (n_ (min))) ~ (0.3), n_ (min) is the minimum spindle speed, n_ (max) is the maximum spindle speed; η is the transmission efficiency. ], The single-speed main motor machine can be easily calculated.
