Torque And Speed Calculator For Gears

Gears are one of the most important mechanical elements that are used in nearly all types of machinery. Proper design and calculations of gears are very important, and this needs an engineering-level approach. When you are designing your gear systems for machinery, you need to know the required gear ratio to obtain the required torque and speed. This article will be a very good reference to calculate your required gear ratio for input and output torques and speeds, for gear pairs.

What Is Gear Ratio Calculator?

Gear Ratio Calculator For Gear Systems

As you see above, you need to enter the required values to obtain output torque and speed from a gear system.

Gear systems are used for generally torque or speed reduction. There is a main shaft that gives input speed and torque to the gear system. This output shaft is assembled to a gear which is called ‘driving gear’. Other gear which is assembled to other shafts, is called ‘driven gear’.

For this calculator, you need to know the input speed and input torque values of the driving gear and shaft system. Then you need to enter the number of teeth of driving gear(n1) and driven gear(n2).

Click on the ‘Calculate!’ button to see the output torque and output speed of the second shaft and driven gear.

Conclusion For Gear Ratio Calculator

Mechanicalland does not accept any responsibility for calculations done inside its calculators. As a good engineer, check your calculations by hand.

Units are very important. Units are not important for this calculator. You will see the ratio of what you entered. But if you need to convert your units into another set of units, you can use the MB-Unit Converter tool.

  1. Gear reduction calc interesting but as a backyard maker using trial and error more than thoughtful foresight as my natural process it seemed too complicated for me to use. I probably didn’t devote enough effort to understanding it!
