Calculating overall gear ratio „i“
Example:
   
 6. gearFinal group
Input gearZG1 = 42ZA1 = 22
Driven pinionZG2 = 31ZA2 = 69

i = Z2 : Z1 → Remark
iG = Gear ratio = ZG 2 : ZG 1 = 31 : 42 = 0,738
iA = Final group gear ratio = ZA2 : ZA1 = 69 : 22 = 3,136
i tot. = total ratio = i G x i A = 0.738 x 3.6 = 2.315
1)  Z1 = Number of teeth of drive pinion, Z2 = number of teeth of driven pinion
