Gear Ratio Calculation

Example:
Drive gear
Driven gear
i = Z 2 : Z 1 (Z 1 = number of teeth drive gear, Z 2 = number of teeth
driven gear)
i G = gear ratio = ZG 2 : ZG 1 = 31 : 47 = 0.660
i A = axle ratio= ZA 2 : ZA 1 = 61 : 18= 3.389
i total = total ratio = i G x i A = 0.660 x 3.389 = 2.237
6th Gear Final Drive
ZG 1 = 47 ZA 1 = 18
ZG 2 = 31 ZA 2 = 61
