Gear Ratio Calculation
Example:
| 6th Gear | Final Drive | |
|---|---|---|
| Drive gear | ZG1 = 45 | ZA1 = 21 |
| Driven gear | ZG2 = 28 | ZA2 = 70 |
i = Z2 : Z1 (Z1 = number of teeth on the drive gear, Z2 = number of teeth on the driven gear)
iG = gear ratio = ZG2 : ZG1 = 28 : 45 = 0.622
iA = axle ratio = ZA2 : ZA1 = 70 : 21 = 3.333
itotal = total ratio = iG x iA = 0.622 x 3.333 = 2.073
