渐开线直齿插齿刀最佳齿形角的求法

The Solution of the Optimum Tooth Profile Angle of Involute Straight Tooth Pinion Cutters

插齿刀的齿形角一般按齿形角修正公式来求,但此时的齿形设计误差不是最小。本文在推导出齿形误差计算公式的基础上,给出一种使齿形设计误差最小的最佳齿形角的求法。

Calculates the tooth profile angle of pinion cutters with the corrected formula of tooth profile angle. However, under this condition, the tooth profile designing error is not smallest. On the basis of deriving the calculating formula of tooth profile error, generates a solution of the optimurn tooth profile angle, which can keep the tooth profile errors smallest.
