To determine gear ratio of a gear train with 2 gears, start by identifying your gears. The gear attached to the motor shaft is considered the first gear, or the “drive gear”, and the other gear, whose teeth are meshed with the drive gear, is considered the second gear, or “driven gear.”
The gear ratio gives us an idea of how much an output gear is sped up or slowed down or how much torque is lost or gained in a system. We equipped this calculator with the gear ratio equation and the gear reduction equation so you can quickly determine the gear ratio of your gears.
The gear ratio is the ratio of the number of turns the output shaft makes when the input shaft turns once. In other words, the Gear ratio is the ratio between the number of teeth on two gears that are meshed together, or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt.
Calculate gear ratios effortlessly with our Gear Ratio Calculator. Understand the relationship between gear teeth and rotational speeds for mechanical engineering and automotive design.
Q: How do I calculate gear ratio? A: The calculation for gear ratio is simple: divide the number of teeth on the driven gear (or output gear) by the number of teeth on the driving gear (or input gear). This can be represented by the gear ratio formula: Gear Ratio (GR) = Number of Teeth on Driven Gear (T2) / Number of Teeth on Driving Gear (T1).

Keep reading our article to find out: What is a gear? What is the gear ratio? How to find the gear ratio of a gear train; How to use the gear ratio to calculate the speed of the output ...
In the simplest formula for calculating gear ratios, divide the number of teeth on the driving gear (T2) by the number of teeth on the driving gear (T1). This gives you a basic gear ratio (GR) for a direct drive mechanism.
To calculate the gearbox ratio, we can use the formula: Gearbox Ratio = Number of Teeth on Driven Gear / Number of Teeth on Driving Gear = 80 / 20 = 4. In this example, the calculated gearbox ratio is 4. This means that for every revolution of the driving gear, the driven gear will rotate four times. The gearbox provides a speed reduction of 4:1.
Use the formula: Gear Ratio = Number of Teeth on Driven Gear / Number of Teeth on Driving Gear. What’s the difference between high and low gear ratios? High gear ratios provide more speed, while low gear ratios offer greater torque. Why are gear ratios important in vehicles?
The Gear Ratio Calculator determines the gear ratio of the circumference and the vehicle's speed in any gear and any engine RPM for the best performance. This enables you to know the relationship between the speed and torque in a mechanical system.
