hi, I need to sketch a gear tooth profile in Pro/E in order to have a mold made. I have the tooth thickness and a pressure angle of 20. I don't know where to go from here as I don't have enough geometry information. I think I need to know the top land thickness, but can't seem to find a formula. The gears I am modeling are 1: external, 64 DP, .5 Pd, 20' p ang, and 2: internal, 64DP, 1.5Pd, 20' p ang. ANY help would be greatly appreciated.
