How to Use the Calculator

Step-by-Step Guide

  1. Enter the Motor RPM (Input Speed) into the first field.
  2. Enter the Gearbox Output RPM (Output Speed) into the second field.
  3. Click the "Calculate" button to get the gear ratio.
  4. The result will display the calculated gear ratio.

Gearbox Ratio Fundamentals

What is Gear Ratio?

The gear ratio is a measure of the relationship between the rotational speeds of two or more gears. It indicates how many turns the input gear must make for the output gear to complete one turn.

Importance

  • Determines speed reduction or increase.
  • Affects torque multiplication.
  • Crucial for matching motor speed to application requirements.

Key Formula:

Gear Ratio = Motor RPM / Gearbox Output RPM

Calculation Formula

Gear Ratio:
Gear Ratio = Motor RPM / Gearbox Output RPM

Example Calculation

Consider a motor with 1800 RPM connected to a gearbox that outputs 300 RPM:

Motor RPM: 1800

Gearbox Output RPM: 300

Gear Ratio = 1800 / 300 = 6

Result: Gear Ratio = 6.00
