3 Calculating overall gear ratio “i”
Example:
5th gear Final drive
Drive gear ZG1 = 39 ZA1 = 18
Driven gear ZG2 = 29 ZA2 = 61
i = Z2 : Z1 1)
iG = Gear ratio = ZG2 : ZG1= 29 : 39 = 0.744
iA = Final drive ratio = ZA2 : ZA1 = 61 : 18 = 3.389
itotal = Overall 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
