3D Tutorial 10: Instantly Modeling Straight & Helical Gears in Blender


In this tutorial, you will learn how to model involute gears instantly using our brand-new online calculator. With the help of this instant gear calculator, a pair of perfectly meshing straight, helical or herringbone gears with involute teeth and profile shifts can be created in under 90 seconds, as demonstrated in the tutorial.

Helical gears are stronger than straight gears due to a greater load bearing surface area, but due to the curved shape of their teeth, they are subject to an axial load. This problem can be solved with the help of herringbone gears. A herringbone gear is essentially two helical gears with opposite hands, stacked on top of each other.



The end result of this tutorial, a .blend file containing a meshing herringbone gear pair, can be downloaded via the link below.
