## Gear Output Torque Formula

The following formula is used to calculate the Gear Output Torque.

To = Ti * GR

- Where To is the Gear Output Torque (N-m)
- TI is the input torque (N-m)
- GR is the gear ratio (Do/Di)
- = Output diameter divided by input diameter

To calculate gear output torque, multiply the input torque by the gear ratio.

## How to Calculate Gear Output Torque?

The following two example problems outline how to calculate the Gear Output Torque.

**Example Problem #1:**

- First, determine the input torque (N-m). In this example, the input torque (N-m) is measured to be 500.
- Next, determine the gear ratio (Do/Di). For this problem, the gear ratio (Do/Di) is calculated to be 3.
- Finally, calculate the Gear Output Torque using the formula above:

To = Ti * GR

Inserting the values from above and solving the equation with the imputed values gives:

To = 500 * 3 = 1500 ((N-m))

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

input torque (N-m) = 150

gear ratio (Do/Di) = 2

Entering these values into the formula or calculator above gives us::

To = 150* 2 = 300 ((N-m))
