Tutorial: How to Model a Planetary Gear Mechanism in Blender

Code Canyon


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 https://youtu.be/DqBOva04lcE first.

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

    After the voice said "tutorial" very sadly … I would like to comfort the poor robot …

    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.

    5:50 It is importent to connect the right point otherwise the bridge tool produces trash … 🙂

    how do you select the top, the bottom and the middle of the gear by one click. please answer fast

    For all the dudes, that arent able to replicate the model – you most likely dont center the 3d cursor at center of the planetary gear (at 12:27), while doing a loop cut and rotating it on Z with 1.5 degrees.
    Thank me later. :)))

    every single time I do this, going over the steps many times, my animation still jumped and glitches all over the place, what do I do?

    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

    Unfortunately, this type of software is highly susceptible to mode errors where the user, following the tutorial, enters the command, but receives errors because the user is in the wrong mode for that command. This is made worse by some commands being written (mouse icon with letter) while others are not (e.g. at 5:15 the mouse is shown with an R for rotate, but the next two commands are skipped: Z and Ctrl+V). In other places, assumption are made about the user's knowledge of the interface. In my case, I can't select the endpoints to connect them. I am certainly in the wrong mode to select points, but the select menu includes scores of options, none of which allow for point selection. With only part of the screen in view, determining if the mode is different and how to get in the correct mode is very difficult.

    …hmm i have some problems creating gears with teeth counts around 200.
    The teeth overlap at their base on regular gears.

    can you give a more concrete way of determining teeth counts with different input and output gears because other wise the calculator is flawed.

    I cant zero my median point. For example in x value I set 0 and then I press enter and i see that the value is 0.0000007. Then i repeat again and value changeing on 0.0000034. WTF is this?!!! ;[ Please masters of Blender help me. By the way how did u marked accurate 1/3 of the bottom vertecies in 14:40?

    Velice krásný tutorial – postupoval jsem podle návodu. Prosím o zaslání blend.souboru – při přehrávání mám trhavé pohyby a ozubená kola se nepohybují plynule.Pomozte moc děkuji

    I followed this tutorial to the letter, but when I play back the simulation, the gears just sort of jiggle in place rather than rotate. What gives?
