英制齿轮

各位大大.
4 P9 }5 u' g, W1 |$ \, X# H$ L" j我这有对齿轮.经过实际测量,得到的数据在PROE里画的齿形总是觉的不想,请大家帮忙一下.

- r' U; s; U6 t1 A& k7 o' hZ1=96
8 f* i8 Y# u; b3 fZ2=384
- k+ h, C  ]+ Wa=20(取标准)
ha=1(取标准)
c=0.25(取标准)
8 R, ~* s$ X+ E中心距=381

I am so sorry to make a mistake.

- u. ~; _4 n! K. v: I' m* ^$ Q你有齿顶圆直径数据吗
通过齿顶圆直径可以判断是否是高变位齿轮
5 t' G; B+ E7 }% ?7 c' A+ _我可以给你算出全部数据
