轴人字齿轮的精度主要是齿分度的精度。在加工轴人字齿轮时,可以在轴人字铣床主轴上安装STI圆感应同步器数显表,直接检测加工中的齿分度误差。我们选用720对极的圆感应同步器,精度可高达±1角秒,重复精度达±0.5角秒。但是其安装工作的好坏,将直接影响测量精度的高低。因为如果定子转子的轴心与回转中心不同心的话,它们的对称绕组所产生的感应电动势大小、相位就不相同,从而有电动势输出(电势值的大小与偏心量的大小存在近似正弦
The accuracy of shaft herringbone gear is mainly the accuracy of the tooth indexing. When processing the shaft herringbone gear, the STI circular induction synchronizer digital display can be installed on the shaft of the axis herringbone milling machine to directly detect the tooth indexing error during machining. We use a 720-pole circular induction synchronizer with an accuracy of ± 1 arcsecond and repeat accuracy of ± 0.5 arcsec. However, the quality of the installation work will directly affect the level of measurement accuracy. Because if the stator rotor axis and the center of rotation is not the case, their symmetrical winding induced by the size of the induced electromotive force, the phase is not the same, so there is electromotive force output (magnitude of the potential value and eccentricity approximate sinusoidal
