Gear Ratio Calculation


This function can be used to calculate the gear ratio with gears. The result is the gear ratio and the advantage. The advantage is the reciprocal of the translation.

Optionally, the transformed speed and the force or torque can also be calculated. A unit of measurement is not given here. It comes out what is entered, so with rotation per minute the result is also rotation per minute. The same applies to the torque.

To calculate, enter the number of teeth for the input and output gears. Then click the 'Calculate' button.
