Calculating Transmission Ratio "i"

Calculating Transmission Ratio "i"

Example:






i = ZG2 : ZG1 *

iG = gear ratio = ZG2 : ZG1 = 29: 36 = 0.806

iA = axle ratio = ZA2 : ZA1 = 68: 26 = 2.615

itotal = total ratio = iG x iA = 0.806 x 2.615 = 2.108

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