伞齿轮在近似铣削时,总是先用公式求出Z’_x,确定铣刀号数后,再选用一定的操作方法铣齿。Z’_x的求法如下:Z’_x=(Z_x)/(cosα)式中 Z_x——被铣削的伞齿轮齿数。α——节锥角,或叫节锥顶角。Z’_x——铣齿时的换算齿数。可是当我厂在制造一批1″/2胸摇钻 Bevel gear in the approximate milling, always use the formula to find Z’_x, determine the number of milling cutter, and then use a certain method of operation milling. Z’_x is obtained as follows: Z’_x = (Z_x) / (cosα) where Z_x is the bevel gear tooth number to be milled. α - section taper angle, or section cone angle. Z’_x - converted teeth milling teeth.
