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 • Tutorial: How to Model Geometrically ... first.

The end result of this tutorial, a .blend file containing the working simulation of a planetary mechanism, can be downloaded from www.otvinta.com/tutorial04.html.

I usually click away from AI narration but I am glad I watched; this is exactly what I was looking for.

12:45 The loop cut Z rotation angle (for tability purpose) is said to be inversely proportionnal to the number of teeths, which i translate as Zrot=1/(Number of teeths)...1/60=0.0116 for the ring (You said 0.6°) 1/24=0.04166 for the planet (You said 1.5°) and -1/12 for the sun gear (you said -3°). I cant figure out how you end up with this rotation angles. Please explain

is it true that the formula for gear ratio = 1+R/S can be used in any circumstance, no matter which one gear out of three is stationary.
@legoman91 6 years ago

followed it exactly word for word, have even compared mine to your downloadable version and somehow mine still doesnt work correctly sun gear drops down before the gears start spinning, have tripple checked everything and nothing is fixing it/getting it to work
@tobiaskarl4939 6 years ago

The rigid body version didn't work for me. Everyting I tried the gears exploded away or they jittered but ditn't spinning around in my version created from this video instructions. The downloaded version works and I don't find out why. So I decided to use drivers and this works perfectly. I want to describe or illustrate mechanical behaviour not to simulate and test a physical model.
