Y33滚齿机加工斜齿轮时,要进行差动挂轮计算,计算公式为: (m_R——法向模数;K——滚刀头数;刀——斜齿轮螺旋角) 其中定数7.95775是无理数25/π的近似值,故上述公式最后得数必须是近似值,运算过程也容易出错。最后还要把计算所得的小数化成精确到第五位小数的近似分数,并要把这个近似分数搭配成实用的挂轮,在机床开动之前有必要将运算结果验算一下,来判断其精度。
Y33 gear hobbing helical gear, to be carried out on the differential wheel, calculated as: (m_R - normal modulus; K - hob head; knife - helical gear helix angle) where the fixed number 7.95775 is an irrational number 25 / π approximation, so the final formula must be an approximate number, the calculation process is also prone to error. Finally, the calculated decimals should be rounded to the nearest fraction of the fifth decimal place, and the approximate score should be matched with a practical hanging wheel. It is necessary to check the calculation result before the machine starts, to judge its accuracy.
