渐开线花键拉刀或渐开线花键轴在磨齿形时,通常是用渐开线砂轮修正器将砂轮修正成渐开线截形。拉刀的模数、齿数或压力角不同,就得换用不同的基圆盘,这就使得基圆盘的备用量大大增加。我厂现在采用圆弧来代替渐开线齿形,使渐开线花键拉刀的加工大大简化。要用圆弧来代替渐开线花键拉刀的齿形,首先就要计算出代圆参数,本文介绍我厂采用最小二乘法计算代圆参数的方法。
Involute spline broach or involute spline shaft grinding tooth shape, usually with involute grinding wheel corrector will be amended to an involute wheel truncation. Broach modulus, number of teeth or pressure angle, you have to use a different base disc, which makes the base disc greatly increased the amount of spare. I now use the arc instead of involute involute, so involute spline broaching process greatly simplified. To use arc instead of involute spline broach tooth profile, we must first calculate the generation of round parameters, this article describes my factory using least squares method to calculate the generation of round parameters.
