40° Pressure Angle, 36 Teeth 4.285 Pressure Angle, Please help
I need to create data for special gear for my customer, this manufacturer no longer make. I am trying to make a model with formulas to accomplish this. The only information that I know is the Pitch Dia, Number of teeth and the pressure angle. I think the pressure angle of 40° is what might be causing the problem. Is this because many machine formulas are based on approximations and this pressure angle is so far from normal the formulas do not work? My Base Circle seems way too small. If you cannot help me I understand.
Thanks in Advance
