Sprocket Speed Calculator

This calculator helps you determine the speed of a sprocket in RPM (Revolutions Per Minute) based on wheel RPM and gear ratio.

Input Parameters

Calculation Results

Calculation Formula

Sprocket Speed (RPM) = Wheel RPM × Gear Ratio

Where:
Wheel RPM: The speed of the driving wheel
Gear Ratio: The ratio of the number of teeth on the driven sprocket to the number of teeth on the driving sprocket

Calculation Result

Sprocket Speed (RPM): 0

Sprocket Speed Calculator Calculator Usage Guide

Learn how to use the Sprocket Speed Calculator and understand its working principles

How to Use the Calculator

  1. Enter the Wheel RPM (Revolutions Per Minute) in the first input field. This is the speed at which your wheel is rotating.
  2. Enter the Gear Ratio in the second input field. This is the ratio of the number of teeth on the driven sprocket to the number of teeth on the driving sprocket.
  3. Click the "Calculate" button to compute the Sprocket Speed.
  4. The result will be displayed in the Calculation Result section.

Understanding the Formula

The calculator uses the following formula to calculate the sprocket speed:

Sprocket Speed (RPM) = Wheel RPM × Gear Ratio

This means that if you know the wheel speed and the gear ratio between the wheel and the sprocket, you can determine how fast the sprocket will rotate.

Example

For example, if your wheel is rotating at 100 RPM and the gear ratio is 2:1 (meaning the wheel has twice as many teeth as the sprocket), the sprocket speed would be:

100 RPM × 2 = 200 RPM

This means the sprocket is rotating at 200 RPM.

Applications

This calculator is useful for various applications including:

  • Designing and analyzing bicycle or motorcycle drivetrains
  • Engineering applications involving gear systems
  • Automotive applications where understanding gear ratios is important
  • Any situation where you need to determine rotational speed in a gear system
