In this article, we’ll guide you through the usage of such a calculator, the underlying formula, provide an example solve, address common FAQs, and conclude with the significance of this tool.

How to Use

Using the worm gear torque calculator is straightforward. Simply input the required parameters into the designated fields, click the “Calculate” button, and the tool will provide you with the torque value. Ensure accuracy by double-checking your inputs before calculation.


The formula for calculating torque in a worm gear system is:


  • T = Torque
  • F = Force applied
  • r = Radius of the gear
  • α = Helix angle of the worm gear

Example Solve

Let’s consider an example where a force of 50 Newtons is applied to a worm gear with a radius of 0.1 meters and a helix angle of 30 degrees:

T≈8.65 Nm

Thus, the torque in this scenario would be approximately 8.65 Newton-meters.
