Calculation of gear ratios

Example:
Drive gear
Driven gear
i = ZG 2 : ZG 1
1)
i G = Gear ratio = ZG 2 : ZG 1 = 33 : 46 = 0,717
i A = Ratio of the final drive = ZA 2 : ZA 1 = 70 : 24 = 2,917
i total = Total ratio = i G × i A = 0.717 × 2.917 = 2.091
1) Z 1 = No. of teeth on driving gear, Z 2 = No. of teeth on driven gear
