Overall Transmission Ratio i, Calculating

Overall Transmission Ratio i, Calculating

Example:






i = Z2 : Z1 (Z1 = Number of teeth on the drive gear, Z2 = number of teeth on the driven gear)

iG = gear ratio = ZG2 : ZG1 = 31 : 42 = 0,738

iA = axle ratio = ZA2 : ZA1 = 69 : 22 = 3,136

itotal = total ratio= iG x iA = 0.738 x 3,6 = 2.315
