Tutorial: How to Model a Planetary Gear Mechanism in Blender

In this tutorial, you will learn how to model a planetary gear drive with Blender 3D, and test it with Blender’s Rigid Body Physics engine. The gears feature involute tooth profiles and herringbone shapes. We recommend watching our Involute Gear tutorial at first. The end result of this tutorial, a .blend file containing the working simulation of a planetary mechanism, can be downloaded from For more free tutorials and 3D models, and to make a donation, please visit .
