Enter the torque, RPM, and gear ratio into the calculator to determine the torque 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?

1. First, determine the input torque.

Measure the input torque.

2. Next, determine the gear reduction ratio.

## FAQ

What is a gear reduction?

A gear reduction is a 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.
