Worm Gears Explained, Calculated & Modeled

In this video we first hand draw a basic worm gear meshed with a worm wheel. Then we take a look at the function of a worm gear assembly and how to find the gear ratio of a worm gear assembly. Then we take a look at a 3d rendering a worm gear and worm wheel animated in Autodesk Inventor.

The subject of Worm Gears often come up in both high school and college physics and engineering classes. They are found in Project Lead the Way (PLTW), Principles of Engineering (POE), and AP Physics.
