Overall Transmission Ratio i, Calculating

Overall Transmission Ratio i, Calculating

Example:






i = ZG2 : ZG1*

iG = gear ratio = ZG2 : ZG1 = 31 : 34 = 0.912

iA = axle ratio = ZA2 : ZA1 = 72 : 22 = 3.273

itotal = total ratio = iG x iA = 0.912 x 3.273 = 2.985

* Z1 = No. of teeth drive gear, Z2 = No. of teeth driven gear
