Name Variable Units Equations/How to Get It
No. of Teeth [ N ] teeth You choose this to get right gear or speed ratio
Pitch (diametral) [ p ] 1 / in N/PD (mating gears must have same pitch!!)
Pressure Angle [ f ] deg. Usually Standard (14.5, 20, 25, 30)
Addendum Diameter [ AD ] in PD + 2*a
Dedendum Diameter [ DD ] in PD - 2*d
Pitch Diameter [ PD ] in You Choose (use this diameter to calculate Torque)
