Sprocket Gear Ratio Speed Calculator


Calculating gear ratios is crucial in various mechanical applications, especially when dealing with sprockets. The Sprocket Gear Ratio Speed Calculator is a valuable tool that simplifies this process, allowing users to determine the relationship between the sizes of different gears and the resulting speed.

How to Use:

To utilize the Sprocket Gear Ratio Speed Calculator, follow these simple steps:

  1. Input the number of teeth for the driving sprocket in the designated field.
  2. Enter the number of teeth for the driven sprocket.
  3. Specify the speed of the driving sprocket in revolutions per minute (RPM).

Click the “Calculate” button, and the calculator will provide you with the accurate gear ratio and the corresponding speed of the driven sprocket.


The formula for calculating gear ratio is as follows:

Additionally, the speed of the driven sprocket can be determined using the formula:

Speed of Driven Sprocket=Speed of Driving Sprocket√óGear RatioSpeed of Driven Sprocket=Speed of Driving Sprocket√óGear Ratio


Let’s consider an example where the driving sprocket has 20 teeth, the driven sprocket has 40 teeth, and the speed of the driving sprocket is 100 RPM.
