Tutorial: How to Model a Hypocycloid Drive in Blender

In a hypocycloid (or simply cycloid) speed reducer, a flower-shaped gear called cycloid disk moves around a stationary ring of round pins in a cycloidal motion, driven by an eccentric bearing or cam connected to the input shaft. Radial holes on the face of the cycloid disk in turn drive the pins of the output shaft. Hypocycloid drives are widely used in the industry due to their excellent characteristics, such as wide range of gear ratios, compact size, smooth transmission, high efficiency, high overload capacity, low noise, long service life, and compact design.

With the help of our tutorial, you can design your own hypocycloid drive in Blender in a matter of minutes.
