我们对圆弧齿轮轴向齿距及其偏差的测量问题作了些探讨。现将所用的方法介绍于下,供读者参考。一、测量原理圆弧齿轮虽然也是斜齿,但它的轴向齿距测量并不能照搬渐开线斜齿轮的方法。后者轴向齿距的测量,要求在大约分度圆柱齿面上进行,而圆弧齿轮却不能这样做。因为一般圆弧齿轮传动,小齿轮的齿廓 We have made some discussion on the measurement of arc tooth pitch and its deviation. The method used now is introduced below, for readers reference. First, the measuring principle Although arc gear is also a helical gear, but its axial pitch measurement and can not be copied involute helical gear method. The latter axial pitch measurement, requiring about the graduation cylinder tooth surface, while the arc gear can not do so. Because of the general arc gear drive, pinion tooth profile
