2  渐开线生成点--》生成样条曲线方案

参考  7.2渐开线齿廓直齿圆柱齿轮（1）_哔哩哔哩_bilibili

xd=`基圆半径rb `*sin(t*PI*1rad)-`基圆半径rb `*t*PI*cos(t*PI*1rad)

yd=`基圆半径rb `*cos(t*PI*1rad)+`基圆半径rb `*t*PI*sin(t*PI*1rad)

 

 

 

 

3 直接生成渐开线曲线

参考  CATIA渐开线直齿轮参数化建模_哔哩哔哩_bilibili

Xx=`基圆直径db`/2*cos(PI *t/2)+`基圆直径db`/2*PI*t/2*sin(1/2*PI *t)

y=`基圆直径db`/2*sin(PI *t/2)-`基圆直径db`/2*PI*t/2*cos(1/2*PI *t)

 

 

 

4 渐开线直齿斜齿轮

参考  catia练习47—斜齿圆柱齿轮参数化建模_哔哩哔哩_bilibili

x=`基圆半径rb`*(cos(PI*t*1rad/2) +sin(t*PI*1rad/2)*t*PI/2)

y=`基圆半径rb`*(sin(PI*t*1rad/2)-cos(t*PI*1rad/2)*t*PI/2)
