What is an Epicyclic Gearbox? | Skill-Lync

In our previous videos, we have discussed the types of manually operated gearboxes. But, the gearboxes that we have seen so far had gears that rotate on fixed axes. In this video, we will be discussing a gearbox that has gears that rotate both on its axis and on some other axis.
We have explained what epicyclic gearbox is, its construction and how it is helpful in achieving different speeds and in changing the direction of motion.
An epicyclic gearbox or a planetary gearset consists of a sun gear, a number of planet gears connected together with a carrier and a ring gear. Of these three members, one is held fixed. One is used as input and the other as the output. By changing these three, different speeds and different directional drive can be achieved.
Automatic transmission systems use a compound planetary gearset and we will discuss that in a separate video. Stay tuned!

2:26 Sun gear is turning the wrong way. The planet gears do not rotate in the popsite direction, but in the same direction, only slower.
To reverse, you need to use the planetary gears as the reaction member.

At 2:28, the animation in wrong, sun's teeth go through the planets' teeth

You should take down this video with wrong info and re-upload the correct one.

Great job, keep it up!

Thank you for your feedback. You made our day! We look forward to continuing to serve you well :)

What is it called when you have multiple layers of planetary gears? For example, if your first inner ring gear also had spurs on the outside too (not sure what that gear is called) connect to more planetary gears and a second internal ring gear?
