4 Easy Ways to Determine Gear Ratio (with Pictures)

4 Easy Ways to Determine Gear Ratio (with Pictures)

Oct 16, 2019 · In mechanical engineering, a gear ratio is a direct measure of the ratio of the rotational speeds of two or more interlocking gears. As a general rule, when dealing with two gears, if the drive gear (the one directly receiving rotational force from the engine, motor, etc.) is bigger than the driven gear, the latter will turn more quickly, and vice versa.
