Base Diameter of Gear
BASE DIAMETER D b is the diameter of the base cylinder from which the involute portion of a tooth profile is generated. In other words to make the output driven gear turn faster than the input driving gear we need a GR less than 1 and must choose an output driven gear with diameter d 2 that is smaller than the input driving gear with diameter d 1To make the output driven gear turn slower than the input.
