Thanks for the link but I'm confused... How do I use these formulas to figure out what I need?
I'm guessing the one I want is OD (outside diameter) which requires you to know N (number of teeth) and Diametric Pitch (P). Number of teeth is no problem we know that. But we don't know Diametric Pitch. So lets take a look at the formula on how to figure out P (Diametric Pitch).
There are 3 different ones.
One requires you to know the OD, which is what we are trying to figure out so thats obviously out.
Another one requires you to know the Pitch Diameter, so I take a look at how to figure out Pitch Diameter.... You need to know the Diametric Pitch!!! So that one is out.
That leaves the middle one, where you can figure out the Diametric Pitch by dividing pi by the Circular Pitch. We don't know the Circular Pitch so lets look up the formula for that...
Circular Pitch only has one formula... CP = pi/DP!!!! You divide pi by the Diametric Pitch to get the Circular Pitch! But we are trying to figure out the Diametric Pitch!
I'm confused, these formulas just go around in circles... Its like trying to figure out what X is in the formula X = Y * Z, not knowing what Y is, looking up the formula for Y and being told that Y = X / Z... !!!!
