The planetary gear set, also known as the epicyclic gear train, is one of the most important and interesting inventions in engineering. They are great speed variation mechanisms, and are often used in automobiles as a vital part of automatic transmissions. We will explore the secrets of the planetary gear set in this video.

3 f***ing weeks to understand this concept at uni and in a 4.52 minutes video you explained more clearly than my teacher. :D

1:23 "that is an impossible condition" It is very much possible, very well documented and often fun to watch from a distance. you may carry on.

Teachers have spent hours trying to explain this simple concept whilst an animation does it in 2 minutes. Thank you.

I need to hold this in my hands to see work.

You guys are doing very great job All animation videos are very good. I am assistant professor in mechanical engineering . I used to show my students. I hope you guys will make such knowledgeable videos related to mechanical engineering. Thanks you

Whoever invented this deserves a cake. Genius.

Best video about this mechanism, not only for the images but for the detailed verbalization in order to understand the logic.

Amazing! When I finally undestand it, Eletric Motors comes and render it completelly useless!

THE EXPLANATION OF THIS SYSTEM WAS OVERENGINEERED...

These robot voices are getting really good!

Nice touch getting Robert Forster to narrate this!👌🏻

after differential this is the best engineering marvel i have ever seen

Great vid! I wish you had one specifically for the Borg warner overdrive, that used the same setup to simply add a gear to a manual transmission and at the same time make it automatic!

Why I'm watching this at 4 AM instead of sleeping? I'm not even into engineering.

Surely, all those views are very good for learning process and also thanks goes to all production-teams! It's me, Sule Shangodoyin.
