Understanding PLANETARY GEAR set !

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.

Whoever invented this deserves a cake. Genius.

[safffff]

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

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

[iAkariQuietly]

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

[matiasmov]

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

I have assembled planetary gear unit set in transit mixer however this video clearly explains a lot thank you 🙏

THE EXPLANATION OF THIS SYSTEM WAS OVERENGINEERED...

These robot voices are getting really good!

I have zero practical need for this channel. I cant stop clicking their videos though.

I’m only 12 but managed to make an entire transmission with this video

Thanks for sharing engineering with a wide audience!

I learned this more easily when I was 12 years old by reading a series of carefully written car books, produced in 1957 and offered for free by GM. Specifically - "Power Goes To Work (In the Automobile)" and revised in 1969. And it does help to be in a calm state of mind. Ha ha.

hi i am kundu . this gear system is a wow wow. i am understanding not before, but after, now i am knowing.many many thanks and bolo jai zuban kesari

[marcdecock]

Also an interesting application: the hybrid drive from Toyota...

[buttonman]

Nice touch getting Robert Forster to narrate this!👌🏻
