Calculate Diametral Pitch (P)• P = N/D = Number of Teeth/Pitch Diameter• Chosen N & D = 26/95 = 0.273Calculate Pitch Diameter (D, d)• D = n/P• D = 22/0.273 = 95Calculate Pitch Angle• Lp = tan -1 (Np/Ng) • Lp = tan -1 (22/22) = 63.43Calculate Addendum (a)• a = 1/P = 1/0.273= 3.66Calculate Whole Depth (ht)• ht = (2.188/P) + 0.002 • ht = (2.188/0.273) + 0.002 = 8.016Calculate Dedendum (b)• b = ht – a• b = 8.016– 3.66 = 11.67
