水文介绍一种实用的圆弧逼近渐开线的花键轴高效磨齿方法及其砂轮修整器,利用计算机寻查最优调整参数,使圆弧与渐开线的拟合误差达微米级,从而保证花键轴磨齿精度稳定在1级。生产实践证明,本磨齿法比国内现在使用的磨齿法,效率要高10倍左右。目前国内工厂磨削渐开线花键轴及渐开线花键拉刀齿形时,通常采用渐开线砂轮修整器修整成型砂 Hydrology This paper introduces a practical method of circular arc approximation involute spline shaft high efficiency gear grinding and the wheel dresser, uses the computer to search the optimum adjustment parameter, makes the fitting error between circular arc and involute reaching micrometer, In order to ensure the accuracy of the spline shaft grinding teeth in a stable. Production practice has proved that the grinding method is currently used than the domestic grinding method, the efficiency is about 10 times higher. At present, the domestic factory grinding involute spline shaft and involute spline broach tooth shape, usually using involute grinding wheel trimmer sand molding
