    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.
