Good luck putting that one back together.
Judas!
thats what i was going to say
This might help.

Piece of cake. Just throw away the parts left over. It works every time.
Roland Anderson no problem
So I am helping my granddaughter take some pictures of her science fair project. shes eight by the way, I move the camera in for a close up and the camera won't focus, so I say out loud Focus you Fuck!!!. I try to cover that up with her as best as I can. A while later she is with her mom and my granddaughter is taking some pictures, I hear her say "focus you fuck" it sounded so cute coming from her,but her mom was mad as a hornet,
Thank you AVE for all of your input in English skills!! My granddaughter and I thank you,
Greetings from New Mexico
Hilleary Brown hello fellow New Mexican!
Does she have a Dolly? Yes? Best gather all your Cockfords and put them in a safe place.
At least she didn't start going on about releasing Schmo you would be in a whole different type of trouble then.
This is a thing...I've used it several times on the jobsite, and everyone just looks at me like I've lost my mind
little girls always reminds me of munchkins from the wizard of Oz.
I mean the voice.

"these things are really expensive. I don't want to destroy this" [hard cut to hammering it apart] :^)
lol, yeah he was beating that like a red headed stepchild.
I luv this guy lol
Ate lunch at a sumitomo factory once. Glad the gearbox is better than the lunch.
Your descriptive prose approaches that of the great Charles Dickinavise.
you win the internet today sir, indeed you do
Brilliant! This might cum-i-late in Wads-worth though...
đ well played and well worded
Why do the Japanese have the best company names? They always sound straight out of the future. Here I am with POWER FIST...
Oh, they have Power Fist, but you can't see it on account of the pixelation.
AvE ..........bro.........fucking perfect
Maybe Japanese genitals are just naturally pixelated? Will confirm tonight at my local izakya.

iza-kyaaaaaa is what you say when you get punched in the balls.
Brand naming has made me go makita 18v, hilti is also talked all around as the best tools but the name also it half close to hilfe, not to mention how expensive they are. Brands like milwaukee I just think it's some rubbish american quality.
Maybe if you took your shoes and pants off you could count to 20 and a half.

"Long story short I don't want to destroy this...." WHAM - WHAM - WHAM - WHAM!!!! His timing is either comic genius or oblivious irony.
Since he manages it on almost every video he does, coincidental Irony theory is impossible...
dude, if you 3d print in ABS, you can vapor polish with a wee bit of acetone. to hell with 'a few hours of clean up' on a print.
Blake D also going slower with a finer tip
MyLonewolf25 - too much information. Sick!
In PLA it works with DCM.
Two words of advice:
1. Very low backlash, agreed. But nobody will tell you the input is not linear to the output! If you plot a chart with the angles measured at the input and at the output, instead of a nice diagonal straight line, you'll get a wobbly diagonal, like a a sinusoidal turned loose on that line! Of course, the effect is tiny, but it's there, inherent in the math of the thing. And if you get the dual stage model, where you have a 1 : 10 coupled to a 1 : 9, for instance, you get the ripple of two asynchronous sinusoidal waves violating that diagonal line...
2. Even using two discs, you never completely mitigate the vibratory effect: you just lower it, by offsetting the direction of the vibration from a perpendicular to the rotational axis to a direction at an angle from it...
Eros Nicolau what if 3 are used to offset each other like a 3 rotor in a 20B rotary engine?
Yee Sen Chai I would imagine it would just divide the vibration points (nodes?) Into thirds. Basically you can always cut something in half but you can never get rid of if.
Yee Sen Chai Oh I know what happens with that one, you get all the teeth sheared off your gears and your rear end will never be quite the same.
Eros Nicolau the winding were of the standard lotuseldeltoid type with two sperbing bearings to effectively reduce side fumbling...
All cycloidal transmission devices have a torque ripple. This is caused by the near zero speed motion when the tooth of the rotor is in the pocket of the stator. The angluar motion switches from about the center of the rotor orbit to the center of the lobe. If you've ever used a spirograph you have felt this (it is uncomfortable when the rolling radius nears zero)
Yet another thing I had no idea existed 13 minutes ago, and now I have to have one. Not for any REAL reason, just to have one in a box what for showing off to the ladies and such.
I'm sure you could find a use for it. Get your lug nuts 43 times tighter than normal. Adjust the hot/cold water setting in your shower 43 times more precisely than ever before! You'll surely think of something.
Get it in your next robot wars crusher weapon?
For real huh. I know what you mean.
Some weird ladies you've got hanging around.
Plus, they're shiny!
anybody else see other peoples videos and find yourself saying "FOCUS YOU FUCK!"?
Chris Moore yes i have i almost post that on a video i was watching but, I caught it before I post it
I used to work at Sumitomo in Chesapeake,VA building these exact same units. Our biggest units were almost 2 tons in weight.This is a very old model but love the vid
Too Shmart That is a place I wouldn't mind seeing. Cyclos are lovely inside.
We have replaced cyclos that I remembered weighing a little less that 4 tons. 6000 series 2 stage 600ish to 1 reduction with 15HP motor.
I would have to check the nameplate, but that location sounds familiar.
You have the strongest banter game on the internet.
Seriously. I have never seen better, especially if it's really all ad-lib, which I suspect it is.
Eggzactly!
A lifetime of experience and too much time talking to yourself should do it.
+lordvore
Yep...I'm betting he turns the camera on, gets into it and forgets it's even there most of the time.
"... sex wax also known as vienerschlieden" lmao!, This guy's got the gift!
My dad was a mechanic. He used to toys with machines like you do. He passed away two years ago and now i watch your channel imagining dad still around. Thans for a great channel
Have used these for nearly 40 years. They are dependable and virtually maintenance free. In fact I cannot ever remember any one of them going out. Which was aggravating because I have always wanted to tear one down. You did it for me. Thanks!
the output shaft with pins in a new direction to counteract the sister shaft - sounds good but wouldn't fit well on a DVD cover
That's indeed an impressive piece of decently engineered mechanics. So compact !
I use these everyday as part of a bigger gear train assembly. Taken apart they are pretty mesmerizing to watch. Think of ones the size you can't even put your arms around, yea they are a pain to put back together. Unless you know to flip it upside down so output shaft is pointing up then pins go in last. Noway you are putting the pins in before the discs.
You are an absolute LEGEND. Thank you so much for the most entertaining and informative videos on the internet.
Keep up the good work - SIR.
Clockwork Orange reference? Did not expect that. As usual, fascinating video.
At the risk of sounding like an ignoramus, what was the Clockwork Orange reference?
He used the slang like Viddy and ultra violence, which are from the book.
To be fair, half the people who use 'ultra-violence' these days have never even seen the movie, let alone read the book.
and there's a lot more to 'singing in the rain' that meets the eye! :-)
what a glorious day!
Glad I wasn't the only one who caught that!
Want to learn engineering AND watch the best comedian out there at the same time? Just watch any random AVE video and your wish is fulfilled! :D
My only problem with uncle bumblefudge is that I've almost snapped a couple of ribs on more than a couple of occasions from laughing too hard, but then engineering isn't without dangers... Never change - always prevail/derail!
Jens Andree that should be this channel's description
Except you don't actually learn any engineering, you learn the very basics of how certain tools function. Nowhere near enough math and physics here to learn anything remotely related to engineering. It's like saying you're learning science by watching discovery documentaries. :P
Most of us here already know engineering and have 30-40 years experience so we are actually quite happy to just have the funny bits ;)
If you want that type of "education" there's school and other ways - but they lack the spirit, humour and the di*k in the vise! :P
derbigpr500 I'm fairly certain the enjunearine is self study, so please take your time and no need for you to rush back at all...... jackass
I learned more about how cycloidal gearsets work just now than I did in 10 years working in the bearing store.
Wailing on the sub-assembly with the ball-bearings pressed in place and/or hammering the ball-bearings in place causes the balls to peen the races that will eventually lead to premature failure.
This is why bearings (ball and roller) should always be pressed on, never hammered.
Tell that to the idiots who install U-joints with a hammer instead of a vise!!! đ
From an ASME welder and recovering CNC machinist, I just want to say that you and your channel are awesome! Even my wife wants to watch for the verbiage and laughs. Thank you sir.
3:45 i fell out of my chair laughing
I always feel smart watching these very interesting videos right up to the point where I realize I'm just an idiot.
7:50 it looks like a caterpillar running around.
8:42 Two contra-phase cycloidals, "minimize" (do not eliminate) vibration. The centrifuguals are neutralized, but since the cycloidals are separated along the main shaft, there is an oscillating torque applied to the angular momentum vector, which exerts a nutating pulse.
this ^^^. It'll wobble back and forth, like a 4 cylinder opposed engine. Even though two cylinders are always going the same direction, they're offset so there's a moment (rotational force) developed.
I learned today.
Have a few beers. That usually reverses that problem.
It's the process of forgetting that's the best part.
Dude, this is one of the best videos I've ever watched on CZcams! You are hilarious! I mean that in the absolute best possible way too! The information is top notch. I learned and laughed while watching. It just doesn't get much better than that. I've subscribed and want to watch all of your content now, thanks! Keep up the great work!
Ordered a hand tool rescue wrench for my Dad's Christmas present last week. Thank you so much for the publicity. It's going to be a cool gift.
I've rebuilt hundreds of those... (actually a larger version) Usually they tear up the bearing & input shaft, sometimes the output gets twisted off.... Very cool design..
The 2 rotor cyclo gearbox still has some vibration. It wants to turn with an axis perpendicular to the input and output. Because the rotors are hopping up and down 180° phase difference you get torque.
You need 4 to balance completely (unless i've missed something). Set them up as a straight 4 engine.
Likely overkill, but if you want insane high speed on that (i don't judge) you should cancel rotating oscillations aswell
You can just use three with the center one being twice the mass and offset from the outers, if we're picking at details.
i stand corrected
That design will balance the free forces of even order but not the forces of uneven order. Regarding free torque it will depend completelly on the fixation point of the gearbox.
TBH this idea came because it reminded me of an engine and as far as i know inline 4 doesn't have weighted rods to cancel torque (no engineering qualification whatsoever)
The cycloidal drive is not going to be a good way to multiply torque, but I think you came to that conclusion already. I have tried to use it a couple times in my job, but since I really am trying to multiply torque instead of reduce speed, it just doesn't work. One of the main problems is that the pins that drive the output shaft are only partially engaged. It is kind of hard to explain, but if you look closely at your 3D printed parts and the contact between the pins and the 6 holes in the gear, you'll see that 1 or 2 are at a tangential point and another 1 or 2 just aren't at a good angle to drive which leaves you with just 1 or 2 pins to do the actual driving. As a speed reducer the cycloidal is amazing, but it just isn't a good idea for high load situations.
Eric i read your hard to explained conclusion. Read more then you will understand more.... half a vessel makes damn lot of noise!
I use one in on a large shot blasting machine in a foundry. The table drive has one it, no idea the reduction, but it puts out enough torque from a 2hp motor to turn a 2000# stainless steel table with 4000lbs of castings on it. Works fantastic.
Omg when you said vienershlide-in, I instantly cracked up, I choked on my beer dammit!
Rockwell Automation actually innovated based on this, they placed the lunar wane shafts in such a way that side fumbling was completely eliminated. This was used in their highly successful Turbo Encabulator.
Just donât ask him to count to 21 ;)
AvE would need to call out the vice squad?
I searched the comments for "21"... that is your 12th thumbs-up. I hope that you get exactly 9 more ;)
A little more than socks Will have to come off. Please let him keep his pants up and not break out the vice.
I can only get to 20.5
...I've heard some guys get to 29. Jerks
He blatantly set himself up for that gag. Still funny though
I made a video series on how i 3D printed the exact model AvE shows, and in the second video I show you how I designed my own. I also make other 3D printing and mechanical engineering projects. I made it for a medical exoskeleton for a student. Feel free to take a Look at it.
I have entirely too many subscriptions, but your commentary forced my hand to click anyway. lol.
I've been watching your videos here and there for a couple years anyway, so what the hell. Good content, world class commentary. A combo for the ages.
That is absolutely engenius, and the way you explained it just clicked. Fuck I LOVE this type of stuff.
Now put it back together and see if it still works!
Why wouldn't it? There is noto much inside them to really go wrong. It should still work. Not without a slight rattle of damaged bearings of course.
Come to think about it - you can make a crappy one real fast using some laser cut steel parts and some bearings.
Jeez man, why do you hit things with bearings on them with a hammer? That fucks them right up.
VEC7ORlt He is using a brass hammer. It's softer than steel. Fucks the hammer right up not the bearing piece.
its a copper hammer vs a case hardened or at worst a mild steel shaft - the only thing getting fucked up is the copper hammer - pause vid at 7:34
And the bearings, which are not designed for axial loads.
You gotta get those bearings off there somehow and it doesn't work to well radially
Your right unless he was holding the bearing on the inner race. And not using the seperator and the rolling elements to take all the load
That may be the coolest thing I've seen in like ten years.
Bloody super cheers AvE
10:26 mmkayy
I absolutely love your "slang." I dont know if im watching for info or just to hear to talk.
Fun and educational video, thanks for this! The dual dynamic elements that are 180-degrees out of phase is the same reason the Wankel rotary engine has two rotors. They really wanted one giant rotor and a counterweight, but...
I work as a millwirgt and took one of these apart a month ago, before watching this video. Was very impressed. I thought they were like a normal gearbox but it's nothing like a normal gearbox. High torque capabilities and very reliable in terms of their operation, very rare to have one break unless the bearings break, or key strips out
Oh, the self healing mat didn't heal at all.
When did the big burn mark happen?
I need to stop following you I think. Just found a 70's metal body drill and called It sexy.
I watch a lot of your videos! I wanted to chime in on your mention about recentering an off center punch. I used to build oilfield pump packages (Skids) gear drive and belt drive. I also rebuilt Industrial Gearboxes. I routinely drilled and tapped new holes for the covers on the Gearboxes including the shaft covers with just a drill and tap. Normally they would be sent to a machine shop for that but I told them it was not necessary and I did many of them without issue. Anyway, I used to just move my punch over but I found the best way to do it is to put your punch in the off center hole you made lean it over at an angle and point it in the direction that you want to move your punch hole in and hit the punch until you think it's where you want it then stand it up at a 90° angle and hit the punch harder. If it's still off center just do it again until you get it where your want it then once you have it centered hit your punch hard enough that it makes the hole bigger than the off center one where the point of your punch is or many times I would just end up overtaking the original hole with the larger diameter of the new one. Works every time. Well, At least if you are experienced and have a good eye it does!
you are an amazing individual. Love your videos.
after u take apart something and see weak points, do u fix them or wait till they let the smoke out?? love this channel keep the knowledge pixies comin. how bout some more longer vids, like 20+ min. the longer the better for me, thanks for doin what u do
horoshow vesh to viddie today me droogies
Sort of new to your channel, cross over from Matt's The Work Shop. I would give my left nuuut to live in your shop and feed off your knowledge and humor. You and your sidekick make my days beerable...keep it up
When you say "treat especial", it really makes it actually feel more special. It feels like you made the video just for me :P
You forgot to mention these bad boys can't be back driven!
Jeff Rosburg Yep same as worms.
This is not the case. We use them in large lifters. I have personally released the motor brake to have the load go down, thus turning the motor.
the raptor guns use planetary gears not cycloidal.... ask me how i know ( hint i fix them daily)
moggys13 how do you know
They need fixing every day? wow
You have a way with word's. Love it.
This dude is funnier than most of the dudes that get up on stage and make people laugh for a living.
what would the efficiency be of this gearbox compared to a standard spur gearbox ?
Friction is most definitely higher, lots of sliding surfaces. There is also going to be a lot of pressure on the offset (Cycloidal?) bearing in the middle as it is pushing the gear around. I'm no expert but thats what it looks like to me.
Cyclops Designs it's the same or higher than spur gears
in a cheap design that i had seen a bike chain was used for the outside pins. as the lobe plates would move the roller on the bike chain would rotate reducing friction. the reducer was for a jack screw that would adjust a satalite dish. so operation was like 100 rpm for 2 minutes once a week ie low usage.
its amazing that just about everything can be balanced but my sex life.
Crystal Soulslayer perfection.
I enjoyed the humor during this demonstration.
Listening to your narration never gets old.
I've heard these called "Grinder Gears", for their characteristic crunching. Last I heard about them there was no known/non-toy purpose. I had no idea they existed as an industrial product.
This things are great! Tough as shit, until you forget that the puddle of oil they are swimming in doesn't lubricate the innards.
Sort of reminds me of the internal workings of a Wankle/rotary engine.
I work in the largest aluminum can plant in the world. We have these gear boxes everywhere, mostly on conveyance. Some of them are easily pushing 30 years old in a can plant that is pushing 60 years old. Very reliable & indestructible - but AvE is correct, run it out of oil and the clipboard are bitching about downtime.
Michael-Michael Motorcycle I have seen one go several hours without oil. Not totally dry, but the oil leaked out through a blown output seal (vertical drive). They sure let you know about it, they howl!
stop saying zoe. cool video even so
You mean cool video even zoe!
A new post just in time for my birthday!!! What a present!
This guy cracks me up with his Minnesota accent and description of all sorts of goodies and gadgets, along with a little fu-k here and there, almost reminds me of Mark Twain with a twang
Where's the Patreon squad that saw this like a week ago
*we're
I have to stop and rewind your videos at least ten times! I laugh so hard at some of your descriptions, I miss half the video! đđ
its worse when you get reminded of something from another video and have to find it now!
Super cool! Thanks for the info I didn't know.
Very cool! Thanks for taking stuff apart!
Super informational video!! thanks!!!
Love the channel1
I really love your video!!!
âI donât wanna destroy thisâ
*starts hammering the hell out of it*
That would make a good 4th axis for a cnc router. No backlash would be awesome! Man I can think of a hundred uses for that thing....one of the coolest things I've seen in a while.
Watched a lot of your videos, thanks for taking the time to edutain us, you sharp tongued grease fiend!
Thank you for such wonderful video. I learned a lot.
Loveed this! Very intelligent explanation and demonstration of how to achieve solid rotational positioning. Where was this guy when I was in engineering school? I graduated in 1968 and three more times so he probably wasn't born before my first degree. Good work and I subscribed. Looking forward to more. Reminds me of a geneva drive.
That is a super clever mechanism.....super cool to see the motion that is usually hidden in a case.
thank you. i never heard of such a thing.
Great video. Never heard of those before so this was very useful for me.
This guy's sense of humor is amazing subbing just for that lol
How can anybody disllike this video? Mind-blowing peice of kit genius engineering! Nice jobđ
Nnnnnifty! That orbitrol valve widget you covered recently suggested something like this was possible. Made me think some. Totally cool now to see it in the flesh.
Thanks for this great vidjeo, never seen one before and run into a pair of them on a job, made me look like a fookin genius knowing what it was hehe đ
That was simple but very cool great idea thanks
Ive always known these as Harmonic Drives. When I worked on laser gear we had a scanner that used one of these for sub-micron resolution at the scan end. Very nice demonstration
Your innuendo cracks me up lol.
Is there an encyclopedia of gears? Seeing gears such as this is a mesmerizing mechanical symphony. Daddy wants more!
this is a genius invention. love the design!
âshlide it onto the shaftâ ;) subbed just for that alone.
you made this fun, thanks. It's that nun on ash wednesday that got me going.
Well that was a very interesting mechanism. Thankyou for explaining! A beer for you!
The tech is interesting and well presented - but the commentary is beyond funny - I lost my lunch when you mentioned the penitent nun :)
out of all these. I like this. and the hydraulic motors and pumps and such best!!!
10:10 Ave: "I don't want to destroy this" literally 2 seconds later: hammering the frig out of that piece till it no longer chooches xD
Thanks! Thanks!Thanks!So beautiful
Started watching to see the design. Kept watching because of the delivery. I can see myself starting to reference rippems and torqueues in the future. đ
Thats very neat.. good job dude, i dig your style đ
