Torque And Speed Calculator For Gears


Gears are one of the most important mechanical elements that are used nearly all the machineries. Proper design and calculations of gears are very important, and this needs an engineering level approach. When you are designing your gear systems for a machinery, you need to know the required gear ratio to obtain required torque and speed. This article will be 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 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 which gives input speed and torque to gear system. This output shaft is assembled to a gear which is called as ‘driving gear’. Other gear which is assembled to other shaft, is called as ‘driven gear’.

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

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

If you want to do another calculation, click on ‘Reset’ button and enter new values.

Conclusion For Gear Ratio Calculator

Mechanical Base do not accept any responsibility of calculations done inside its calculators. As a good engineer, check your calculations with hand.

Units are very important. Actually, 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 sets of units, you can use MB-Unit Converter tool.
