I show how to model a ring gear, how to set up planets, carrier and sun, joints and motion links, and making helical/herringbone sets. I'm using Fusion360, though it should work fine in other CAD software, and I 3D print the set to show you that it works.

  • Another amazing video on gear design. This is the most detailed and easy to understand video on planetary gear design i have come across so far. Great work Antalz !
  • Watched the whole series at once! Great material and I hope you continue to post these very informative and clear material. Greetings from Brazil!
  • Been looking forward to this video for a while, I've saved it to my list of videos I need to watch when I've got a bit of free time from school. I've had several projects in mind that would make use of a Planetary Gearbox.

    Whoa..it's amazing how professional your materials are and how well You can cover given topic. I really appreciate your work, thank you and keep it going!
  • @omaraissani6255
    This is the second time that i watch this video & not missing a second ! the content in this channel is outstanding i hope that the community gets bigger
  • @deeeeeds
    Your tutorials are really some of the best out there. They're so much more practical than most other ones. I swear every tutorial says, "this is the gear tool, thanks for watching" but you actually show meshing gears together, joints, pitfalls, etc. It's amazing.
  • I really appreciate your teaching style, all of my questions are answered! Take this sub :)
  • Thank you for the way you clarify these complex issues. I'm a designer not an engineer. Your explanation of the principles and the step-by-step walkthrough in F360 allows me to do do more modeling before sending it off to the engineers for their review.
  • @one.darkstar
    I was making the model while watching, and at almost 5 mins in, my power got cut. I'm grateful you said we're gonna start from scratch again haha
  • @grandpa9595
    Great Job!! It does not seem that long when you are watching it. Thanks!!
  • @rohansharma991
    Thank you for a better teacher than my professors in the various Machine Design classes I took. Some of the best videos I've found on practically designing gears.
  • @puneitsingh
    Awesome content. Thank you for taking the time,& energy to make such informative videos.
  • @abhinavsixfaces
    Wow. Amazing tutorial. You have such a great way of explaining things. Thank you so much!!!
  • Thank you for the video. I have learned a lot about gears. Best regards from Germany!
  • @johnkeelan
    Thank you for creating such a great video! Even a fusion novice like me can follow along and create this amazing model.
  • @rawn9911
    Thank you for sharing a top notch tutorial!
  • @AmsSma
    Great video, l learned a lot. Thanks for sharing your knowledge. Waiting for more videos.
