齿轮参数求解！！急！！

yz790110

接了个做齿轮的活，给了一些参数，作图时好多参数不明白，希望高手指点！谢谢

1 模数m=22
2 齿数z=14
3 压力角 20
4 精度等级9-9-8-dc
5 刀具移动量 x=14.52
6 齿顶高系数fo=1
7 齿全高h=44.235

只有这些系数，不明白刀具移动量时什么意思！网上也查不到。希望哪位高人给算一下，翻译成国语！（cad画图时用的数据）谢谢了！

你 把图纸发上来窥窥……

JINLIANG

移位量=模数X变位系数

yz790110

变位系数怎么算啊？我只有上面这几种数据！谢谢了！
图纸太模糊，而且给的是整体图，不是齿轮的单件图。扫到网上也看不到。谢谢了！

wangzy6010

变位系数=变位量/模数

yz790110

高手们！谢谢了！我只有上诉的7种参数，请大家根据上面的参数给个答案！谢谢了！变位量什么的都没有啊！
