在滚齿机上加工齿轮时,由于有几何偏心和运动偏心,就会引入被加工齿轮的齿距误差和齿距累积误差,影响齿轮传动的准确性和平稳性。 齿轮在加工时,几何偏心和运动偏心是同时存在的,引起的齿距误差均是以齿轮一转为周期,按正弦规律变化的,其综合影响结果,可按矢量相加合成。这样,就可设法使其相互补偿,消减齿距误差和齿距累积误差。 Gear hobbing machine processing, due to geometric eccentricity and eccentricity, it will be the introduction of the gear tooth pitch error and pitch error, affecting the accuracy and smoothness of gear transmission. Gear machining, geometric eccentricity and eccentricity exist at the same time, the resulting pitch error is a gear cycle, according to the law of sine changes, the combined effect of the results, can be synthesized by vector addition. In this way, you can try to make them compensate each other, reducing pitch error and pitch error.
