## Gear Torque Calculator (Formula)

The Gear Torque Calculator is used to calculate the gear output torque (To) based on the input torque (Ti) and the gear ratio (GR or Do/Di). The formula for calculating the gear output torque is as follows:

To=Ti∗GR

Where:

- To represents the gear output torque, which is the torque delivered by the output gear.
- Ti represents the input torque, which is the torque applied to the input gear.
- GR represents the gear ratio, which is the ratio of the diameter of the output gear (Do) to the diameter of the input gear (Di). In the formula, it is represented as Do/Di.

This formula is straightforward: the gear output torque is equal to the input torque multiplied by the gear ratio. It is used in mechanical engineering and design to determine the resulting torque in a gear system, where the gear ratio represents the mechanical advantage gained or lost in the system.
