How to Calculate Gear Ratio in a Gearbox
Gear ratio is a fundamental parameter in a gearbox that represents the ratio of the number of teeth between two gears. It determines how much the output gear rotates in relation to the input gear. The formula to calculate gear ratio is:
Gear Ratio (GR) = Number of Teeth on Output Gear / Number of Teeth on Input Gear
Here’s a step-by-step guide on how to calculate gear ratio:
- Identify the input and output gears in the gearbox.
- Count the number of teeth on the output gear (the gear connected to the output shaft).
- Count the number of teeth on the input gear (the gear connected to the input shaft).
- Plug the values into the gear ratio formula: GR = Number of Teeth on Output Gear / Number of Teeth on Input Gear.
- Calculate the gear ratio by performing the division.
The gear ratio provides insight into how much the input gear needs to rotate to achieve a certain rotation of the output gear. It influences torque, speed, and direction of rotation in the gearbox.

What is a Gearbox and How Does It Work?
A gearbox is a mechanical device that transmits power and changes the speed or torque of a rotating input shaft to a different output shaft. It is commonly used in various machines and equipment to control the speed and direction of motion.
Here’s how a gearbox works:
- Input Shaft: The gearbox receives rotational energy from an input shaft connected to a power source, such as an electric motor or an engine.
- Gears: Inside the gearbox are a set of gears with different sizes. These gears mesh with each other, and their arrangement determines the gear ratio, which defines how many revolutions the output shaft will make for a given rotation of the input shaft.
- Output Shaft: The output shaft is connected to the machinery or equipment that needs to be powered. As the gears rotate, the motion and power are transmitted from the input shaft to the output shaft.
- Gear Ratio: By selecting different gear combinations, the gearbox can change the speed and torque of the output shaft. A higher gear ratio results in higher torque and lower speed, while a lower gear ratio provides higher speed and lower torque.
Gearboxes play a crucial role in various applications, including automobiles, industrial machinery, robotics, and more, enabling efficient power transmission and speed control.
