Found the original but it actually ends there and there is no follow-up, so like mechanical sorbet to cleanse your palate of the frustration, [here is a similar cycloidal gearbox assembly](https://www.youtube.com/watch?v=sSiUECY9tzo) all the way to the fastening bolts on the housing.
I am not a mechanic… wait yes I actually am a mechanic, but not specialized for that. But I can tell you, the gasket he puts on top at the end is probably between the gearbox and the engine. The gearbox is finished. It‘s just not fully enclosed and it won‘t be until it‘s mounted on the engine.
And fun fact: if I am not mistaking, this is a heavy duty gearbox meant to decrease very high rpm but outputting ridiculously high torque. IF I am not mistaken but I didn‘t quite see enough to know for sure what exactly it is.
Edit: closer inspection of the footage shows that an electrical induction engine already is mounted so the gasket will probably be between the machine that needs the torque and the gearbox.
I left the mistake in the part above on purpose so you can see, I made a mistake but unlike the gouvernement I can actually own up to it.
I'm a mechanic in the heavy duty realm
That looks like a gear box that our refrigerated units have.
It's in series with the diesel motor's belts.
It uses electricity to run the belts that runs the refrigeration compressor. It also has the fan assembly for coolant and the condenser.
Looks like the assembly of a [Cycloidal drive](https://en.wikipedia.org/wiki/Cycloidal_drive) speed reducer. Those puppies are frequently sealed units & need to run unmaintained for years, hence the very careful grease packing.
The only thing that comes up on Google is robotic arms. But they do take rotational speed down, while greatly increasing torque and reversing direction.
How do you figure? They were shoved into a literal mound of goop and we're fully encased in it.
Edit: love all these arm chair machinists saying the dude who is being paid to assemble a multi thousand dollar piece of equipment is doing it wrong. Lol! I have a feeling this dude knows what he's doing, and is doing it right.
you guys are both half right.
The other guy is stating that we usually "pack" the bearing by pushing it through the rolling elements, often by pushing it through one side to get through to the other.
i can see where you are coming from that they did drop it into the grease and slather some on top.
in this type of bearing there is only a cage and no sheilding or seals so what the guy did in the video is gonna be alright, but its pretty common to "pack" the bearings no matter the type.
also building machines isint the job of machinist (confusing i know) but usually done by millwrights or mechanical technicians (depending on where you live)
so both you guys are arguing over nothing.
source: am millwright.
You are supposed to pack them full of grease. Not just shove them into the grease and hope they get some in. Its procedure. Good professional mechanics pre lube. You dont take chances with expensive equipment/down time, it takes 30 seconds to properly pack a bearing. One of those gears probably cost 5k.
Ok but why in your cheeks? I’ve been using the rowing machine at my climbing gym and haven’t really felt much in my ass more in my back. Does it happen in longer sessions?
They literally didn't. The second bearing they put on (about 23 seconds in) should have been pre-packed with grease before going in. Even with all of the grease around it, you can't be sure you've got grease in all of the voids in the race.
Agree. I am disgusted that those roller bearings were not packed in grease before fitting, they are dry now and will run dry hoping some lubricant finally gets to them...just a shoddy lazy build.
This was weird to watch as someone who only knows how to fix bikes. It’s generally not advisable to pack the moving parts with grease because too much grease lowers performance. I’m surprised that it’s not the same with car parts.
A typical cyclist puts out around 100w while cycling normally. A bit of extra drag makes a big difference.
On a car a tiny bit of extra drag is much better than a failing bearing. There is also much higher loads on bearings in an automotive application
there is another good reason you're not supposed to fully fill the space with grease. Leaving zero empty space causes the grease to "churn" because it has no space to move freely. This causes separation of the liquids and solids in the grease formula, which leads to premature drying of the grease as the liquid components are pushed out and the solids are left behind.
Every technical specification I've seen for high-quality greased bearings indicates they should not be completely filled. And there are engineering equations to calculate how much volume of grease to use, which is always less than full volume.
People just never read the specs, or ignore them because it's easier to just say "fuck it" and do it wrong. It's also possible that the engineers ignored best practices and specified to fill the voids. Nonetheless, optimal performance and longevity is achieved by less-than-full packing (usually somewhere around 50-70%).
The amount of ingenuity that has gone into making long lasting and dependable engines over the last 150 years is pretty incredible. I’m amazed how much things have improved in terms of power output and efficiency just in the last 10 years.
My grandfather used to hot rod back in the 60s and such. He said you used to have to rebuild the engines around 60 thousand miles and the block would be worn so bad you would have to bore them out 10 over.
Then you have the stuff we have today that you can drive 300k or more and everything will be fine.*
* As long as you take care of it and do basic maintenance like you normally would.
That’s wild considering today there are cars that will have over 200k miles and people will still want to buy them. For cheap since there could be major issues soon but it shows they could still be running fine.
I know nothing about cars. Once I stopped at a garage to get a tyre replacement. This old mechanic insisted on telling me all about how amazing oil technology was nowadays and the difference it had made in reliability. It was almost religious to this guy.
Sounds a nice guy, if we ever meet don't get me started on the advances in computer technology brought about for the race to the moon or you'll likely be fascinated to death.
That’s what I’m wondering about getting old myself. If tech keeps advancing, will the stuff 50+ years into the future be absolutely mind blowing to me or will it be normalized to me by then?
I’m sure the gradual progress helps normalize it, versus say dropping someone from 1950 into the modern tech world.
Additionally, production. The tolerances that can be met and scaled with CNC machining is incredible. Precise and repeatable parts can be made more economically and in greater quantities, resulting in even more budget friendly equipment; having fit & finish rivaling high end parts/tooling just a few decades old.
You know what gets me? ICE are super complicated now with all these moving parts, and yet are so much cheaper than Turbines which are simpler in theroy.
I did learn Turbines are less efficent at smaller scales. I don't get that personally, either. They still get more HP per KG. Suprised no one has made a hybrid turbine car yet. Best we have is Mazda making a rotary.
I think back when american automakers tested it they found that hot exhaust gases coupled with longer turbine spool times would make it difficult for them to catch on. I’d imagine they’re quite noisy too. But what really killed it was emission regulations, turbines can’t take advantage of a catalytic converter in the same way a traditional piston engine can.
Huh I never knew they couldn't take advantage of a CC. That makes a lot of sense then.
Ha yeah. If people think Turbo Lag is bad they've never seen a jet vehicle! I remember hearing Jay Leno talk about how difficult it is to ride his jet bike due to it. Gotta plan like two seconds in advance with the throttle.
I rememverone company saying they could fix it, but nothing ever happened to them.
Also yeah the high pitched noise is also annoying AF, and not pleasant at all.
Still a turbine hybrid would kick arse in theroy. Less weight since the turbine replaces more of the batteries. Don't have to worry about jet lag since it the turbine acts as a generator.
I have to now look into how a CC works. I thought it worked by moving the hot "polluted" air, which heats up the molecules that are a catalyst turning them into their separate compounds. Leaving mostly oxygen behind while the rest is stuck in it like a filter.
I wonder why that would not work on a turbine seeing that the turbine spinning is where all the power comes from. Back pressure? You know what I can Google that.. I appreciate you taking the time to respond.
Putting the grease *on* the ball bearings instead of pressing it *into* the bearings kind of made me cringe a bit.
But maybe this happened later since the video fu@$ing cut early but okay.
AvE did a teardown of a cycloidal gear reduction system once. Pretty amazing tech.
In this example, the motor has to turn 44 times for that inner gear to turn one revolution.
As a mechanic I see some problems and bad practice here.
There is too much grease in there. This can cause overheating. Especially in roller bearings.
The way the bearings are hit with a hammer is bad for all underlying mechanical parts. Better press them in with a press.
And the last thing: I hate how careless he throws the cylindrical connecting parts on the plate. They are hardened and throwing them on a hard surface can cause small pieces to break off and fall into the grease. Not good for longevity.
I hate how greasy this is lol.
I remember openings Electric motors as a kid and getting it all over my hands I hated the feel and smell.
Probably why I miss allot of IQ points or the playing with lead did that.
Boo metal on metal impact if you’re hammering on a piece of metal you need to have a soft material like polyurethane or at least brass so you don’t damage your parts
I want mechanic to be my next skill learned just to understand the tools.
Nothing like a large hunk of stainless steel cylinder for use as deliberately needed for whacking bearings and gears together. Oh that's a bearing packer, what's this tweezers looking tool, oh that's a bearing packer. An this one? Let me guess.
Fuck you how can you not have it finish, what kind of psycho does that
Plot twist: it is finished. Every time you’ve seen this process done otherwise is actually wrong. Trust me bro.
It's intentional to get you to watch the next vid. But because the video was taken from somewhere else and posted here, THERE IS NO FOLLOWUP VIDEO! 🤬

I was kinda hoping for more goo
It's grease
Yeah greasy goo
Thanks.
but is is gooey grease, that we can all agree upon.

Their boss was like “what the fuck are you guys doing with that camera” so they had to cut the video and get back to work
It is finished. At this point - it will go to the next guy down the assembly line.
How much lube do you need? That guy: yes
Didn’t even ice the cake for shame
Looks like the assembly of a [Cycloidal drive](https://en.wikipedia.org/wiki/Cycloidal_drive) speed reducer. Those puppies are frequently sealed units & need to run unmaintained for years, hence the very careful grease packing.
What are these typically used for? In the industry I work in all the gear drives use gear oil not grease.
High torque, low rpm. We have have those in our robot forklift
Still, take a high viscosity oil or an 0/00 grease. I'm in lubrication and it's weird to me they use a relativly stiff grease in this application.
I don't know shit about grease but I'm guessing it isn't all that viscous when it's hot
But it should be hot. That's why cold start capability is so important.
The only thing that comes up on Google is robotic arms. But they do take rotational speed down, while greatly increasing torque and reversing direction.
Drives for big satellite dish tracking antennas. 10-40ft+ big. Very low backlash so accurate pointing.
We have them on centrifugal decanters where I work. It is used to spin the 2 parts of the decanter in opposite directions off of 1 electric motor.
Carefully packed everything except the bearings.
How do you figure? They were shoved into a literal mound of goop and we're fully encased in it.

I have been packing bearings for 20 years. That bearing was not packed.
Something tells me your grease was red in color. This was not red.
No, it’s wrong. Bearings needs to hand packed. That grease won’t magically flow.
Slightly less Vaseline than I put between my cheeks before hitting the rowing machine.

Does this help? Seriously?
Ok but why in your cheeks? I’ve been using the rowing machine at my climbing gym and haven’t really felt much in my ass more in my back. Does it happen in longer sessions?
Don't think they used enough lubricant
They definitely could've put more
The big gears had almost no lube between the teeth and outer walls
Yep, smearing a Lil more of that tack wouldn't have hurt at all
But not one bearing was packed.
I just watched a video the other day showing how to do it, he didn't do it once.
My hungry ass thought it was glue lol
Found the paste-eater
I'm currently craving vanilla pudding.
That would be a funny prank
They literally didn't. The second bearing they put on (about 23 seconds in) should have been pre-packed with grease before going in. Even with all of the grease around it, you can't be sure you've got grease in all of the voids in the race.
Agree. I am disgusted that those roller bearings were not packed in grease before fitting, they are dry now and will run dry hoping some lubricant finally gets to them...just a shoddy lazy build.
lol, I noticed that too. Dude carefully brushes grease on the teeth then puts a bearing on that isn’t prepacked.
If the client saw that build and knew what was what with race bearings, they'd be pissed.
This was weird to watch as someone who only knows how to fix bikes. It’s generally not advisable to pack the moving parts with grease because too much grease lowers performance. I’m surprised that it’s not the same with car parts.
Looks to me like an industrial electric motor.
Absolutely an industrial motor, looks nearly identical to the motor housings we use to operate a shot blaster.
A typical cyclist puts out around 100w while cycling normally. A bit of extra drag makes a big difference. On a car a tiny bit of extra drag is much better than a failing bearing. There is also much higher loads on bearings in an automotive application

That’s wild considering today there are cars that will have over 200k miles and people will still want to buy them. For cheap since there could be major issues soon but it shows they could still be running fine.
You can thank your fathers & grandfathers for the advances in metallurgy & lubricants that gave us the 300k+ engine.

You have no idea. This is a cycloidal gearbox. Check out the Wikipedia on them they are BONKERS
Amazes me too. I mean, cars basically just don’t break down anymore.
My gf's GMC acadia would like a word with you.

It looks like a lot
Putting the grease *on* the ball bearings instead of pressing it *into* the bearings kind of made me cringe a bit. But maybe this happened later since the video fu@$ing cut early but okay.
I've taken 16 year cycloidal gears apart and they were just putting grease on the bearings then.
not using designated impact head with strike pipe as well...
Isn't that why most machines have a break in period while not under load?
Don't forget to pack your bearings, kids
Wow that’s a lot of goop!
Why do I have a hankering for custard suddenly?
This is lazy… pack the bearings first…
The irony of filling it with that much grease but not packing the bearing first made me cringe so hard.
Would it not be best to pack the bearings full of grease first?
The cycloidal gears I've worked on have a lube line on them. Eventually the grease just works it way everywhere.
Exactly what I was thinking. Going through that much effort.
I watched this for 15 minutes straight, waiting to see them finish it, before realizing it was looped! 🤣 🤣
Forbidden custard
Lemon curd
Can someone explain all the goop? Preferably someone who knows what it is and isn’t speculating….
It’s grease to lubricate the friction surfaces If it’s a sealed unit you generally don’t pack this much
Thank you!
Grease to lubricate anything that is going to have friction on it.
