Transmission Ratio “i”, Calculating

Example

 

6th Gear

Final Drive

Drive gear

ZG1 = 43

ZA1 = 25

Driven gear

ZG2 = 35

ZA2 = 69

i = ZG2 : ZG1 

1)

iG = gear ratio = ZG2 : ZG1 = 35 : 43 = 0.814
iA = Axle ratio = ZG2 : ZG1 = 69 : 25 = 2,760
itotal = total ratio = iG x iA = 0.814 x 2.760 = 2.247

1) Z1 = Number of teeth on the drive gear, Z2 = Number of teeth on the driven

gear
