BOLTR: Helac Rotary Actuator

[@hydrogen18]

This must be what those guys at quick lube shops use for tightening oil filters.

[@WhatUpTKHere]

+hydrogen18 lost it at this. XD

[@AreThereNoMoreNames]

+hydrogen18 Most of that is just not lubing the o-ring. I'd tighten the hell out of them, but I'd lube the o-ring, which resulted in me being the only one who could get them off, and after getting called into the pits whenever we had one of my cars come back to get the filter off, I ended up just staying down there forever. One of the tough-guy managers even chewed me out because a filter I put on was "stuck", but I could get it off by hand, but he wouldn't lube his.

[@SchrottiJr]

Well drill two holes and stick your Chineseum-mild Steel facewrench in it.

[@rich1051414]

Meh, these days I just throw a strip of sandpaper inside the strap wrench if I am unfortunate enough to have to use one of those things. I will go out of my way to get a proper socket for the filter if I can though.

[@SchrottiJr]

As we idotic Germans are, we started putting fucking extra boxes for oilfilters, that can be opened with fucking normal wrenches or nuts and are tightened to spec with a torque wrench but not with the fucking note on the cap to oil the seal before putting it back together.

[@NickiRusin]

[@GunFunZS]

Nick Nirus * people who make their own. This guy ain't necessarily an engineer, and lots of engineers don't really think that way. People who think that way do, whatever their trade.

[@NickiRusin]

GunFun ZS Fair enough.

[@GunFunZS]

Nick Nirus I know engineers who work out of catalogues an CAD libraries. i.e. Aerospace guys for instance. They have to be able to document the failure rate of anything they work on, so "I made it work" will never fly. They buy something proven or don't make a move. You'll find lots of welders, fabricators, mechanics, handymen, etc. Who make the tools they need. Actually a lot of people get burned out as enginers because they like to create, go to school and never get to create. Their day job is to "draw out the thing we have been making for 100 years, but this time, do the math to see if we can get away with substituting this cheaper bolt..." or "put in all the locations for fasteners on this thing your boss got to create" Small business owners are really the guys who tend to be in the magic Venn overlap of "identify need" "design it" "build it", "improve it". If they are good at that, they tend to suck at letting other people have autonomy though, and they usually also suck at running the office. The rare guy who is good at inventing a thing, making it, and marketing it, but lets someone else be good at ordering supplies and accounting, / customer support is the guy who has a good live.

[@jzytaruk]

GunFun ZS exactly.. lots of engineers will "Design" a tool to work but lack any fabrication skills.. I fab the "odd" tools i need for work.. easier than sourcing them and quicker for the most part...

[@betabenja]

most useful thing about your videos: comments about what not to do and how to tell if you're in the middle of doing it: spitting out fluid? stop; find out where the pressure is. does not free up when unscrewing? stop; might be pre loaded. think how many fingers you have saved your viewers

[@brandonb9452]

betabenja Precisely. Thanks to uncle bumblefuck I still have both mine left

[@gr1nder07]

Yupp! Almost made the mistake of trying to open an relief valve for a 3in high pressure line. Half way through unscrewing a plate that surely had a beefy preloaded spring behind I remembered hearing "if it doesn't loosen up when unscrewing it might be preloaded" and realized my stupidity. En la basura!

[@garth849]

Spot on. Captured large springs scare me more than high voltage, and as a maintenance machinist I encounter both regularly. You can put a meter on a line and check for voltage, you don't have a meter to tell you how much tension or compression is on a captured spring!

[@joshuajohnson5193]

"if youre handed a wrench, that doesn't mean your qualified" Starts bashing it with said wrench while under 1500psi of pressure. Thats my guy

[@uglybob0072]

I liked it when the wrench slipped off and he then said it had reached the correct torque. Lol. I call adjustable wrenches 'nut f*^kers' for a reason!

[@brettwalkom948]

You my friend have no idea

[@orppranator5230]

To be fair, he was smacking the 1 1/2" thick plate on the end that bolts to something. Not the thinnest part that holds pressure, like the walls.

[@baronoflivonia.3512]

Air and any fluid can kill. We had 3 Contractor Plumbers killed in mid 90s, while putting in a 16" water meter. They did not bleed air slowly. It was a 16" 150 psi water main, but it was coming off a 72" transmission main. And they were in vault because north of Detroit it gets cold. Pay attention to his safety advice.

[@joshm3484]

Stephen Paraski I do find it a bit odd that most people seem to think that static hydraulic pressure is somehow more dangerous than air though. I've probably burst over a hundred tubes and cylinders between 1500 and 12000psi and its more of a cumshot than an explosion due to incompressability. 3000psi air or even 300 though can easily kill.

[@baronoflivonia.3512]

They were 9' underground with 2-36" manholes as acess to a 10'x18' vault. When the hammer broke that 16" line the volume of water negated any chance of escaping. They did not have any "Retreval Device", after which became mandatory for entrance but are useless as line becomes entangled in enviroment.

Like looking at an old friend. Used wrenches with their own hydraulic motors to bring large (300+mm) bolts or nuts up to their proper torque specs. Mainly on Wartsila marine engines, the kind where you open an access hatch to enter the crankcase. It took twice as long to position and anchor the tool as to torque the fastener!

Geeez

[@johntate4638]

I was thinking about that when he got the oil on his hands.

[@peteydoesit]

Hydraulic injection! For me that's the most frightening part of hydraulic systems. A friend of my father's ran his finger down a backhoe line that was leaking, pinhole shot it down his middle finger into the palm. Had to have half the hand cut out because of necrotic tissue.

[@joejimmy3273]

I am a diesel and hydraulic mechanic and we work on JLG man lifts and the basket rotator is damn near identical to the one your working on. They are a pain to rebuild and they usually start leaking around the seams from all the dirt and trash around it.its cool to see some one else with one doing the same.

[@awldune]

For anyone who has worked on camera lenses, those helicals are bringing up some bad memories!

[@MikeBaerman]

It didn't occur to me until today. I work with a smaller version of this on a fairly regular basis depending on the truck I'm driving. The regular piston type hydraulics used to do the same job as this one break a lot more frequently and are more sensitive to abuse. These rotary types are damn near bulletproof. Nice to see how they work turning linear motion into rotation. Sweet.

[@thedevilinthecircuit1414]

These are bombproof because all moving parts are contained inside the cylinder. Linear rams extend and retract, and that is what makes them less robust.

[@Rick_Dunaway]

The Best / Easiest to use, thread sealant i've found! LOCTITE 545 (High Temp) LOCTITE 565 (Fast Cure) I like it because it allows you to clock your fittings however you want/need cause its sets up where you leave it.

Man, i am a contractor and a half ass home shop maker.

I stumbled on a few of these vids 3 months ago and have become completely addicted. This guy knows the real deal on everything, and though the occasional relevant tool review & teardown got me subscribed, the brilliant lessons in real world mechanics, equipment manufacturing & design has literally turned this into my houses most watched form of media, bar nothing. My 10 yr old son and i have actually found words like skoocom in our father son vocab, as well as now using the occasional thickly accented Canadian slang phrase when we run into generally preventable fuckery in something that should be better done, Thanks for what is obviously a huge effort put into actual dynamite content!

These are pretty sweet actuators because they integrate both rotary actuation and a pivot shaft (as it runs on two tapered roller bearings) unlike most motors which are only good for powering another piece (thick of a motor and a slewing bearing.

[@SetMyLife]

Fuking hell man, I cannot wrap my head around the functioning of that device. Also, "Release the schmoo!" should get it's own T-shirt.

[@Teth47]

Jaroslav Malec The larger helical gearset moves up and down inside the cylinder, engaging with the stator gearset on the outer casing, that forces it to rotate as it moves upward. Inside that, that smaller shaft's gearset engages with the inner teeth on the larger gearset, causing it to rotate. Basically, imagine a hydraulic cylinder pushing on a rack that rotates a pinion and you've got the basic idea. It's a pretty efficient and compact way to translate linear motion into rotational motion.

[@SetMyLife]

Teth47 Right, so it cannot rotate indefinitely, it has limits.

[@Teth47]

Jaroslav Malec Yes, One full rotation if I were to guess.

[@Teth47]

***** Woot! I've got the explanation of its operation right as well, correct? I didn't look it up, because I like to play it fast and loose

[@GunFunZS]

banana5616 Thanks. I was guessing something like a tool holder on the end of an arm that only needs to rotate so many degrees and then return.

[@GunFunZS]

***** "banana..." said it was used on dumpster trucks and excavators. Any idea what they used it for on excavators? the best guess I could make was to drive the thumb on a compact excavator. They have little ones that will even fit on pickup trucks, for getting into tight spaces without smashing stuff up. It could work for that kind of application.

Rebuilt quite a few of them. Aerial work platforms like JLG, Genie, Skyjack, ect... use them for platform rotators. They suck getting back together as the 3 spiral splines are all timed so it doesn't rotate too far to one side and damage the boom, cat track assembly, wiring/hoses, or platform.

Oh, man. Yes, tell me. I was set to work on a hydraulic system that had NPT 1/2" fitting in and among the assembly. The hydraulic pump had to be rebuilt. But I was putting the hammer down until I found that little nugget. Yea, nugget of el crapola. Could have sliced me clean into multiple pieces, I know you know what I mean. It was a ten thousand pound test on cast/machined fuel pump housings. Production line. I had zero drawings, nothing. Just cold death waiting for me. I should have run screaming from that place the moment I reported for duty. Long story short. That machine I fixed and brought up to "code." What nailed me down the road; a machine with no drawings, cycled on me while I had a screwdriver and my hand/fingers. Flywheel system released, shattered the screwdriver, shot metal up into my face, thru my upper lip, along my teeth and skull bones and stopped just under my left eye. Also broke my right index finger into seven pieces. Was a little story of caution for you. They were pissed that I had to go to the emergency room, but bled all over the shop before I was taken to the Doc. Some people. Heh? My wife about spewed and fainted when they brought me home.

[@jrtcomputers]

In the aerial lift equipment market, we see these actuators alot on boom lifts. They use them for rotating the man basket at the end of the boom. Have had to do many teardowns and re-seals on them over the years.

[@SeanBZA]

Gotta be a beatch to bleed that if you do not have it prefilled during fixing, getting that last bit of air out so it will not hop around if the fittings are below the piston will be a lot of cycles. Even simple linear actuators mutter about that, especially if you want to have a repeatable step with varying loading or are using feedback.. At least the bar tending robot will be able to serve a drink even if there is an inconvenient body in the way of it slewing, though said body might be somewhat inconvenienced by the motion.

[@JoshBettiol]

Their amazing pieces of work. We use them at work on our drills to replace cylinders. Ours are quite a bit bigger though

[@WAVETUBE84]

31,000 ft/lbs of torque! That's pretty massive. Yep, hydraulic actuators are only limited by the crankshaft that drives the pump and the amount of pressure that the lines can handle. They use hydraulic pressure to test air compressor tanks, scuba tanks, etc. If the tank fails/pops it only cracks open, no explosion.

[@prairiewanderer5040]

WAVETUBE84 The you're looking for (or more likely, already know), is hydro-testing. They use water not hydraulic oil.

[@WAVETUBE84]

prairie wanderer I used the word "hydraulic" : that means any fluid. Yes, they do not use petroleum oil for testing those tanks. Water is what is used and it works perfectly. Plus no need to use additional petroleum solvents to clean the tank. Just blow it dry with some warm air. And any petroleum vapor mixed with oxygen/atmosphere and pressurized in an enclosed container past 234PSI will EXPLODE!!!!!!!! Diesel engine ring a bell.

[@prairiewanderer5040]

WAVETUBE84 I was pretty certain from reading your post you knew all about it. My words were for the benefit of those less-informed. I've heard a story or two of someone lubricating the threads on an O2 cylinder before mounting the regulator. Not a happy outcome.

[@WAVETUBE84]

prairie wanderer Put a drop of oil on a tiny (.177") cotton wad. Put that into a pellet rifle, after a pellet, and see what happens. Poof, bang, crack! Nothing dangerous, but you will have a small diesel detonation. Don't know if you get any additional velocity out it though.

More of a neck shake than a twist of her hips! On a much larger scale, it's older more robustly devastating brother is mounted on the backhoe bucket of an excavator and allows the bucket to dig left or right instead of just back to front. Only the lady's should be using the back to front technique! SKOOKUM AS FRIG! We built them that way. MURICA!

NFG? No Fucking Good?

[@eiseklompstra]

Aaron16 Officially Not For Go. Or at least that's what you tell anyone who looks offended when they ask.

[@MrAndrewmcgibbon]

Thats how they write "Does Not Chooch" in Azerbaijani.

[@fogn1]

This term is used in on set film/tv production as well. Some people use the sanitized "NG" version

[@taofledermaus]

Aaron16 Very close to "FNG".

[@themadmailler]

Aaron16 "Not Found Good" ?

[@Jack_Mehoff_]

We make these at my work they are used on excavator mounts or garbage trucks that pick up wheelie bins. Can also be an advantage where space is limited for mounting a traditional cylinder

[@StephenFarthing]

Now I understand why here in England a big hammer is called an “American Screwdriver “ :-)

[@SnowleopardPearl]

AvE is all Canadian, not american xD

This is the coolest fucking channel on YT. I've learned so much in the few weeks I've just been binging this stuff on my downtime. I hope you keep at it, Sir.

[@dogbuggy32]

how did you know I had a 64oz big gulp ?.......that's scary

[@ThePostApocalypticInventor]

***** Very interesting: Here is a huge difference between our channels. Though Americans are my largest audience they only comprise 21% of the total viewership. India, Germany, The UK, Australia and Canada combined make up another 30 percent. The rest of it is very equally spread over the entire globe.

[@dogbuggy32]

lol what I think

[@dogbuggy32]

I am loving my Canadian brothers keep you stick out of the grinder

[@ThumbDr]

The Post Apocalyptic Inventor did you reply to the wrong comment bud? Or did someone delete their comment

[@danielwerger5641]

mmmm.... Very interesting. Wish I had bought those gear hobbers years ago, beautiful helix-xes . And hats off Chris for the warnings about hydraulic circuits, pressures and such. Even 3000psi is deadly.... Cheers and keep up the de-construction. Cheers, Daniel.

Wtf a Boltr I haven't watched... We must fix

[@jonathansmith359]

i worked in hydrulics for 10 years and we had one of these in which I had apart to play with and reseal but never had a clue what it was called

[@dfgdfg_]

14:00 "fruity sh**", or "pretty sh**" ?

[@waynep343]

at 16:16 look at the wear on one of the male acme threads... something got in there and wore half the flat outer surface.. probably what wedged it. and prevented easy operation.. you can just see a dull grey area that on all the others is a full shiny area.. just an observation..

[@disgruntledscientist]

Power for arm wrestling bartender? Better reinforce the bar top.

[@Moggity]

Hey AVE, We use the HKS rotary actuators on the machines we build at the place I work for. The biggest we use is about the size of half a 44gal drum.. Cheers from Australia

[@Moggity]

For sure :) I was out scrounging around the other day to see if we had an old PVG floating around that was being scrapped. I found a few 6 bank PVG32's that I'm going to keep an eye on.

[@whatbuttondoipush]

BANANA FOR SCALE! hi from imgur!!!

[@TheHuesSciTech]

I've often wondered -- when screwing in a pressure gauge like that, you do it up until it's tight, right? So doesn't it end up facing an arbitrary direction, facing the wrong way half the time? Or can you stop a revolution or two short of the point where it won't go any further and still achieve an adequate seal?

[@patrickcharette2151]

Your commentary pretty much got my subscription within 1 minute

[@mrbasher]

Reminds me of a focusing helicoid inside a camera lens. The principle is very similar. Open one up and check it out. What's more interesting is that tube of MolyKote at 16:40... Which is actually awesome for lubing said focusing helicoids. (not likely the same type as you have there though)
