How to Determine Gear Ratio
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. We can express this basic concept with the formula '''Gear ratio = T2/T1''', where T1 is the number of teeth on the first gear and T2 is the number of teeth on the second.<ref>http://bowlesphysics.com/images/Robotics_-_Gears_and_Gear_Ratios.pdf</ref> [[Category:Car Maintenance and Repair]] [[Category:Cars & Other Vehicles]] == Steps == === Finding the Gear Ratio of a Gear Train === ==== Two Gears ==== #Start with a two-gear train. To be able to determine a gear ratio, you must have at least two gears engaged with each other — this is called a "gear train." Usually, the...
