Enter the torque, RPM, and gear ratio into the calculator to determine the toque and RPM output after gear reduction.

## Gear Reduction Formula

The following equation is used to calculate the output values of a gear reduction.

OT = IT * GR

ORPM = IRPM * GR

- Where OT is the output torque
- IT is the input torque
- GR is the gear reduction ratio
- ORPM is the output RPM
- IRPM is the input RPM

## Gear Reduction Definition

A gear reduction is defined as the change in torque with respect to a set of interlocking gears.

## Gear Reduction Example

How to calculate gear reduction?

**First, determine the input torque.**Measure the input torque.

**Next, determine the gear reduction ratio.**Calculate the gear reduction ratio.

**Finally, calculate the output torque.**Calculate the output torque using the equation above.

## FAQ

**What is a gear reduction?**

A gear reduction is the change in RPM or Torque of a rotating object due to two or more interlocking gears. These gears will cause corresponding objects to rotate slower or fast depending on the size of the gears.

**What is a gear?**

A gear is a circular device that when paired together with another gear, produces a change in rotation speed due to different diameters.
