Calculating Transmission Ratios

Calculating Transmission Ratios

Example





i = ZG2 : ZG1*

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

* Z1 = no. of teeth drive gear, Z 2 = no. of teeth driven gear
