Calculating overall gear ratio „i“
Example:
   
 5th gearFinal drive
Drive gearZG1 = 39ZA1 = 18
Driven gearZG2 = 29ZA2 = 61

i = Z2 : Z1 → Remark
iG = Gear ratio = ZG2 : ZG1= 29 : 39 = 0.744
iA = Final drive ratio = ZA2 : ZA1 = 61 : 18= 3.389
Overall ratio = total ratio = iG x iA = 0.744 x 3.389 = 2.521
1)  Z1 = No. of teeth on driving gear, Z2 = No. of teeth on driven gear
