My formulas are like the following:
betaM is helical angle at pin center, it can be caculated this way: tan(betaM)=2xpixrM/T where T is the lead.
find out the psi and then put into the following equation,
This is for external helical gears, the result is smaller a little bit then the classice formula.
Two pins are not in the same transvers section of gear, but they sit in gear channels steadily.
