Excerpt from Spur Gearing: Rules and Formulas Internal Spur Gears Design of Spur Gears
If the outside diameter equals the number of teeth 2 divided by the pitch, which we have already proved, than the number of teeth plus 2 must equal the outside diameter multiplied by the pitch, and subtracting 2 from this result we have the number of teeth in the gear.
Example - Given a gear 3 inches outside diameter and 12 pitch, to find the number of teeth. Multiply 3 (outside diameter) by 12 (the pitch) and we have 38, and subtracting 2 from this result we have 36, the number of teeth in the gear.
