Gear Ratios
Gear Ratio Calculator: A gear ratio is a measure of the relationship between the number of teeth on two gears that are meshed together. This ratio determines how much the output gear rotates in relation to the input gear. Understanding gear ratios is crucial for optimizing performance in mechanical systems, such as vehicles and machinery. This calculator helps you determine the gear ratio, output rotational speed, and output torque based on the number of teeth on the input and output gears.
How to Use the Gear Ratio Calculator
To use the Gear Ratio Calculator, input the number of teeth on the input and output gears. Enter the input rotational speed and select the appropriate unit from the dropdown menu. Input the torque value and choose its unit as well. Click the "Calculate" button to view the results, which will display the gear ratio, output rotational speed, and output torque in a table format. Use the "Clear" button to reset the inputs and results.

Frequently Asked Questions (FAQs)
What is a gear ratio?
A gear ratio is the ratio of the number of teeth on two meshed gears. It determines how the input speed and torque are altered in relation to the output speed and torque in a mechanical system.
How do I calculate a gear ratio?
The gear ratio can be calculated by dividing the number of teeth on the output gear by the number of teeth on the input gear. For example, if the input gear has 20 teeth and the output gear has 40 teeth, the gear ratio is 40/20 = 2.
Why is gear ratio important?
Gear ratio is important as it affects the performance of machinery. It determines how torque and speed are modified, impacting efficiency and capability in various applications, including vehicles and industrial equipment.
Can I use this calculator for any type of gear system?
This calculator is designed for basic gear systems. While it provides quick calculations, it may not account for all real-world variables such as friction or load, which could influence results in complex systems.
What units can I use in the calculator?
You can input values in various units for both rotational speed (rpm, rad/s, Hz) and torque (Nm, kgf.cm, J/rad, Ibf-ft, Ibf-in). Ensure that the units you select correspond with your calculations.
What does output torque depend on?
Output torque depends on the input torque and the gear ratio. The formula to calculate output torque is: Output Torque = Input Torque × (Input Teeth / Output Teeth).
Is the calculator accurate?
The calculator is accurate based on the inputs provided. However, inaccuracies in user input or overlooking real-world factors can lead to erroneous results. Always validate results with practical testing.
