Enter the input velocity and gear ratio into the calculator to determine the output gear ratio velocity.

Gear Velocity Formula

The following equation is used to calculate the .

GV = IV * GR

  • Where GV is the gear velocity (output velocity, m/s)
  • IV is the input velocity (m/s)
  • GR is the gear ratio

What is a Gear Velocity?


A gear velocity describes the output velocity of a gear system given an input speed and velocity ratio.

How to Calculate Gear Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Gear Velocity.

First, determine the input velocity. In this example, the input velocity is found to be 30 m/s.

Next, determine the gear ratio . For this problem, the gear ratio is found to be 4/1 = 4.

Finally, calculate the Gear Velocity using the formula above:

GV = IV * GR

GV = 30 * 4

GV = 120 m/s
