Answers for Abharshit: "To which gear shaft is engine shaft connected?" This planetary gear is only for explanation. Any of three basic elements (sun gear or ring gear or carrier) can be connected to engine. "As which gear is driver and how driven shafts are connected to main shaft?" Shaft is conected to sun gear. It hase multiple kinematic states, as you can see on my video. Which element is driver and which is driven depends on kinematic state and direction of power flow. (Example: Ring gear is held stationary, sun gear is driver and carrier is driven element) In this model, there are not any bearings, input/output shafts, houses or anything else. It is not a gearbox. It is only explanation of planetary gear kinematics.
.Thnx man. for the vid.my current course(mechanics of machinaries) is a very hard one if you physically dont see how the system works.my proffessor just gave a tons of math problem without explaining anything.you saved my life to tell the truth.
Excellent animation. Maybe throw a timing mark (e.g., a dot) on the input and output gear/shafts to 'see' the reduction (skip the planet gears, just the carrier if it is rotation).
very beautiful animation, questions below. assuming that you can change the gear size and teeth numbers. but limit the ring gear diameter ~ 3.5 inches if i set the planetary gear shafts fixed (as shown at 2:48) and i "manually" spin the outside ring gear as hard as i can, would it be possible to make the sun gear to spin the same speed as typical electric screw driver (~2500 RPM).
Pleace for give me if hart you feelings. I have lukihäiriö i do not know what is in engish. This video is the best planetary gear video what i ever seen. Peace out and rock on.
Hi Karol Thanks for sharing this video. I have a question about self locking advantage in gears combination. I want to build rotary head for my CNC, and I want to use a good combination of gear which have a self locking advantage, does planetary gear have this advantage? (something like in worm gear) Thank you so much Regards
HI, wats the software did you used to make this animation? Did you recorded the movie in original designing software and merging the video or you have done full animation in any animation software ?
Hello, I created animation in original software (Autodesk Inventor 2013, 5-6 parts) and then i merged it in the Windows movie maker. I couldn't render full animation, because there is a problem with creating a long videos. But the animation in the original software is continuous scene, only camera moves.
***** Hi, thank you for good question. Here is answer. "Efficiency of helical gear is less because helical gear trains have sliding contacts between the teeth which in turns produce axial thrust of gear shafts and generate more heat. So, more power loss and less efficiency." "Advantages of the helical gearSilent operation: In a helical gear train, the teeth engage a little at a time rather than the entire face at once. This causes less noisy power transfer in case of helical gears.Non-parallel shaft: Helical gears can be used for transferring power between non parallel shafts. Though you have to compromise on efficiency in this case.Strength: For same tooth size (module) and equivalent width, helical gears can handle more load than spur gears because the helical gear tooth is effectively larger since it is diagonally positioned."

+10babiscar Hi, automatic transmision system use clutch for each gear set to control ratio. You can find better answer for your question here th-cam.com/video/u_y1S8C0Hmc/w-d-xo.html.
Hi, The first case (Stationary ring gear) is confusing, sometimes the ring and and planets seem to turn in same direction sometimes in opposite o.O Nice vid anyway
+Larry Panozzo It was moving the right way when rotational speed was slow but then as rotational speed increased, the ring gear and planetary looked like they were moving in opposite directions. I guess we both caught it-JJ
+Larry Panozzo look up wagon wheel effect. Basically, the gear is spinning at just the right speed where the teeth look like they're moving backward rather than forward.
Hi, driver gear varies trough animation (1.ring gear , 2.sun gear, 3. sun gear, 4. sun and ring gears ). I cannot drop music because TH-cam wont let me. Maybe I will make new (proper) video.
Justin Williams Thanks for good question. Answer: It cannot function properly without carrier ("arms"). Carrier (frame witch connecting all planets) is one of three basic elements of planetary gear.You need to control rotation speed of two elements to obtain required parameters of third element. In simple planetary gear one element is held stationary (at zero speed). In differential gear you need to control speeds of two elements. Music is "Marilyn Manson - Resident Evil Main Theme"

Ariel Lezen Planetary gear has many advantages compared to simple gear. Some of them: 1.Ring gear, Carrier and sun gear have same axis, 2. Higher efficiency 3. Higher transmission ratio than simple gear with same size., etc. Simple explanation: Planetary gear has 3. basic elements ( sun gear, ring gear and carrier with planets) and 4 basic states you can see in my video. First three states are with grounded one of the three basic elements. Fourth state is when all elements are free to rotate (differential). "I meant, if one gear is spun nothing happens to the others" - For example in time 1:33 you can see that sun gear is grounded. Now, if we rotate ring gear, carrier will rotate too in same direction. In time 2:14 ring gear is grounded. If we rotate sun gear, carrier will rotate in same direction again, but there is different ratio between them. In time 2:45 Carrier is grounded, now if we rotate sun gear, ring gear will rotate in some ratio in opposite direction. In time 3:18 all basic elements are free. There you can see on the start that, when ring gear and sun gear rotating in same direction with same speed, carrier will rotate in same direction with same speed . If we decrease sun gear speed (In time 3:36) you can see, it will automatically decrease speed of carrier too. In this state I can control speed of carrier (change of speed ratio between ring gear and carrier, this can not be done on simple gear)
So when you say grounded, do you mean locked? If so why don't car or CNC router drill boxes get stuck under any load? By the way thanks for explaining all this to me
Ariel Lezen Yes, you can say 'locked'. They won't stuck under load. For example: in automatic transmission there are three or more planetary gears and few clutches. Clutches (something similar to clutches in car with manual transmission) are used to stop one of the basic component on each set of planetary gears by connecting selected component to the frame. They should not stuck by themselves (only in some cases when we need it - self-locking differential). In simple gearbox, ring gear is usually part of the frame/box.

Instructions were unclear.
Accidentally built a flux-capacitor.
looks like umbrella corp also doing some experiments with planetary gear
Pretty intense film about epicyclic gears.
This demonstration was excellent. Thank you.
thanks for the animation! it was really useful for understanding how gearboxes work!

Very good animation to understand the dynamics of planetary gear train.
A nice post. Thanks
Ok what is this
Awesome designing and animation work man !!

Great animation, and I like the music, thank you.
I love planetary gears and used them every change I get.
really helpful - no way to not like this - beautifully done!
Came here to learn! Now I just want to watch Resident Evil!
Used to have this tune setup as the loading screen for my old DayZ mod server.
Nicely done. Great music.
This and a C.V.T. video gave me a great idea.

really good thanks , you are helping a lot! keep on going....please
Very well done, I have a question about the simulation in inventor: did you managed to obatin the moment of the link in the Output Grapher?
nice resident evil theme

Amazing
Planetary gear is used in wind turbine and many other place where difference between input and out rpm is more.
Very cool, what program was this done in?
beautifully explained.
ahhhhh resident evil! love it!😃

Cool!
Very very Helpful .. Thanxx a lot Sir ,,
Song from 1:00 and onward is from the resident evil movie
thats fcking Biohazzard !
any tutorial on how to build this amazing thing?
pretty awesome
Thank you
The video is helpful
excellent .... thanks bro
nice, genius
Come for circumference ratios, stay for the animation. It should be titled "Hypno-Gears!!". I Watched it twice.
Amazingg..!!

Can the ring gear rotate ? Is it a rotatable part?
qual programa uzaram para fazer isso ???
portugal
Can you make the Sun Gear oblong shaped? So that the axis will wobble.
THANKS GREATE
sound like horror movie
I had that in my engineering exam in Germany. I understand why you are feeling that way.
you're actually right, its the theme for the first resident evil movie
it is a horror movie
That's stolen from Metriod Prime lol
What exactly is the input shaft connected too? Is it the connected to the sun gear itself? Or the planet carrier?
Input shaft is connected to sun gear.
What is the purpose of the angled gear teeth? Wouldn't strait teeth be just as effective?

what's the title of the background music?
The mechanic's fidget spinner.
so does the system use brakes or locks to control which ratio is active?

Simplified Planetary Gears
Hi,
The first case (Stationary ring gear) is confusing, sometimes the ring and and planets seem to turn in same direction sometimes in opposite o.O
Nice vid anyway
It's an optical illusion. They always turn together.
Sir...can you share catia parts file of this plzz?
Very nice, but your animation isn't right from 1:38 to 1:45 - the ring gear was going the wrong way.
+Larry Panozzo It was moving the right way when rotational speed was slow but then as rotational speed increased, the ring gear and planetary looked like they were moving in opposite directions. I guess we both caught it-JJ
+Larry Panozzo look up wagon wheel effect. Basically, the gear is spinning at just the right speed where the teeth look like they're moving backward rather than forward.
Mhm I know that effect. That might be the case here...I can't tell for sure.
I just realized this music was in one of the Resident Evil movies lol
Music is beat fam
what is the driver planet carrier or sun gear. Drop or delete the music and an instructor and ID all the parts.
Hi, driver gear varies trough animation (1.ring gear , 2.sun gear, 3. sun gear, 4. sun and ring gears ). I cannot drop music because TH-cam wont let me. Maybe I will make new (proper) video.
Could you share the number of teeth in each gear? 😅
What happens if the arm is taken away? Also, this music sounds like the song oxycotton.

So what is the point of the gearbox if moving either one or the other side doesn't affect anything on the other side?
Hi, I don't understand your question. It's not a gearbox. This is only a "planetary gear" animation.
