插齿刀经过一段时间刃磨或采用较大的前后角,都会使齿形误差增大甚至超差。本文用最佳一致逼近理论,对理论齿形误差进行优化处理,给出了最佳修正参数的计算式及齿形误差的计算式。齿形表面按照最佳修正参数进行磨削,可使齿形误差减到最小。 Gear shaper sharpening after a period of time or the use of a larger angle before and after, will make the tooth shape error increases or even worse. In this paper, the best consistent approximation theory, the theoretical optimization of tooth profile error, given the best correction parameters and tooth-shaped error calculation formula. Toothed surfaces are ground with the best correction parameters, minimizing the tooth profile error.
