Sorry for my poor English. Thank you, let me use "equation" instead.
From the link you show me, and the equation I read from book, both get the same result. But the book and some other books do not show me how this equation comes. but for other equations, like over pin meassurement for spur gear, span meassurement, I can understand them.
I just don't like the way - the equation I use, but I don't understand it.
For spur gear, I can give the equation from two pins with different diameters, just because I understand.
