I think it's just a place where they showcase different types of gear systems. It's just for showing it and teaching people instead of something real, but for a few sustems I'd really like to know the use case!
I've been in industrial maintenance and repair for over 20 years and I still can't get enough of this stuff. Something is either wrong or right with my brain.
@@jimswordsnchords1759 The word "Art" was on my mind the whole time. I would definately visit a museum having this on display. Maybe it is the Autist in me (like watching a wasmachine while it is working), but it was really relaxing for me. What the purpose was of these gears is not that important for me. I still got a ton of LEGO, maybe gonna build something myself.
This is one of my favorite videos ever, I even watch this when I'm sad lol It fascinates me how simple mechanisms can create a wide variety of movements that can be useful in so many ways.
That one and the one right after it are my favorites! I actually have come to hate the one at @2:55 because it gets the most comments and seems to catch the eye of n00bs who don't understand that it actually doesn't do anything other than look cool, but nevertheless they want to argue about it.
VertikalDesign it’s cool looking though! It was used in a fake Doctor Who intro a while back I liked, along with most mechanisms near the end like the square gears, the oval and round one where the round one moved back and forth, the spiral shaped gears, etc... P.S. I know nothing about mechanics so don’t murder me for lack of knowledge.
@@TheEmeraldMenOfficial the oval gears give a variable speed. The shaft rotation rpm changes as the teeth move farther away from the center line of the shaft.
I've always enjoyed the oddly shaped gears for variable speed operations and such. Just shows how you can make any movement starting with a circular motion from a motor.
But you still have lathe woodworking, cnc machining, high voltage switch gear and industrial shredders to view! Than there's my favorite, smoking & bbq video's, which just leads to me eating 2 pizza pops and going to bed.
The physical forms translating into rhythms in this video just blew my mind. This mechanics used are so old, yet I know nothing about them in this digital age. Absolutely amazing!
Do you mean the title is misleading? Because that's actually the name of the original video. But thanks, your comment perfectly illustrates the reason for the down votes.
+Max R I don't believe you're that gullible; it is the actual title and not misleading at all. I do believe that people will vote down for a dumb reason. But at least you made a comment about it.
Richard Gates. Hello, a title should be a representation of whatever its for or from, that's got nothing to do with gullibality. False advertising is a crime for a reason, because we all understand that a title is suppose to be close to what its for; in itself, or else its false.
I've seen some of these at work in Stephenson and Franklin Poppet valve gear for steam locomotives. Living in the digital age, it's fascinating seeing the mechanical machines of the industrial revolution.
Was this recommended to anybody 10 years later? (also, PLEASE read the rest of this comment before replying) edit 1 (6/6/2020, 2:38 PM central time, USA): As in, when this video was posted onto TH-cam, not when it was first created back in 1930
If anybody was wondering, this ( th-cam.com/video/N4WA1gcIJio/w-d-xo.html ) is the full version of "Mechanical principles" by Ralph Steiner The version of it here starts at 5:13 and ends at 9:28, about half-ish of the full version
Holy moly...that was down right hypnotic, engaging, entertaining, relaxing yet motivating, beautiful and intriguing. Now if I could just find a relationship that worked like that I would be set.
Seems as if we are going backwards in time...the obsession and creativity with gears keeps increasing as time goes by. Really happy to see this though🔥
Only the mechanical minded can appreciate what is happening here. This video is quite enlightening and reminiscent of my days in school. Could give some ideas on ways to solve a few problems for those who care to look.
I feel like this is a kind of beauty that is all but lost today. Don't get me wrong, electronics have done wonders for us, but there is a kind of mesmerizing hypnotic-ness to mechanical motion.
@@laurean5998 actually it's something used where perpendicular force driven by torque to the teeth would be too great. It's a way to increase the contact surface without making the gears triple it's width (depth)
@@supersonictumbleweed Why would the contact surface be bigger than that of a normal straight cut gear with the same diameter and tooth width? Do you have a link? Im pretty sure there is 0 torque applied to the teeth of gears, only radial and tangential (and axial in helical gears) forces resulting in or out of a torque in the shaft. Do you mean this can somehow reduce the radial force? That just makes no sense, you'd have to change your teeth to do that.
That is awesome extremely clever but also simple. Every clip I just imagined the machine around them. But some mech blew me about like the tumbling gears almost looking like ther falling over. Also the oblong gears I never thought that would work but someone thought to put a spring in. Wow. Mechano wasn't really around my childhood much but I'll be sure my kids play with it. When their not wrighting code as homework for the school to build phone apps and games for extra income. Which I do think will happen if not already I know primary school kids are already being taught it but not sure if the schools have started profiting some how from it.
Awesome design! A brief pause, followed by a brief period of high speed, follow by a long period of low speed. All achieved through ingenious piece design! I'm sure it's hard to think of initially, but it actually isn't really that confusing once you break it down :D _(The timing appears to be 25% pause, 25% fast, 50% slow - or roughly 0.425s pause, 0.425s fast, 0.85s slow over its approximate 1.7 second cycle)_
(I'm in highschool) I love the looks of mechanical engineering because of how anti intuitive these things are, and also have no idea what's happening, can't wait to study mechanics !!!!
+muffel91 Quite of few of them were used for specialty applications, like timing and counting, but very few of these would be good for power transmission. And there are several in the video that are completely impractical, other than looking damn cool.
Yeah I only saw maybe, like two or three that were just mechanical thought experiments. Most of the ones involving the Reuleaux which I think was a popular curiosity at the time

These gears are, to the best of my ability to research, are located in or around the green stairwell of the museum of science and industry in Chicago. As far as I know, they're Borg-Warner gear assemblies from the circa 1933 century of progress fair in Chicago Borg-Warner exhibit. However, I am unable to find photographs of said installation online.
The Boston Museum of Science has all those gears in the Clark Collection. They used to have an entire wall of them. Now they only display one or two at a time mixed in with other exhibits. You can find pictures if you Google it.
8 years late... sorry. 😁 I love those old mechanisms in the stair well too! I have a couple of photos on flickr... live.staticflickr.com/4250/34170157574_800affe975_b_d.jpg and live.staticflickr.com/4199/35014015475_47ebdabe39_b_d.jpg I'm not sure that they are the ones featured in this video, but certainly very similar.
Harald Hedgefond you would be correct: the first movie that had sound debuted just three years prior, and “talkies” wouldn’t have hit the mainstream until Gone With The Wind came out.
The reason this 'feels good' to watch, for many people, is because you are most likely a 'problem solver' and 'tinkerer' type. And while you dont know it, your brain in some part, is recording the geometry of these movements, in an effort to help, in the event that you would have to fashion some own version for yourself. :D
I don't know for sure, but they remind me of a swash plate in an a/c compressor. I imagine they could be used to actuate several sets of reciprocating pins in tandem.
No, they have absolutely no practical purpose other than looking cool. (as opposed to most of the other gear sets in this video which actually perform a transform function, where the input and output are not the same)
Jeremie Small quite the opposite, really. Consider the total package length the assembly requires and that it's only using like 20% of the available face, it's weaker than a gear of the full width. Additionally, this diagonal interface requires the teeth to be "in phase." Meaning you can't just put them in any orientation, the peaks must meet the peaks. Cool effect, but zero commercial application.
Bizzhatesme ??? The diagonal gears take up more space than normal straight gears of the same face width. They serve no purpose other than looking cool.
How do you thumb this down? Do you not understand it, or is it not cool enough for you? I'm a CNC Machinist, and understanding that without this we wouldn't have a lot of the things everyone holds so dear. Think about it!
Oval gears are used in flow-measurement of fluids. Oval and triangular and other shapes of gears are useful when you want a movement that starts slowly, goes at high spead for the most part and then slows down as you reach an endpoint of some sort. The other types of gears, sprockets etc you may find in for example factory automation where you want to move things in irregular patterns. And of course in clocks.
What is the reciprocating system at 3:45 called? Anyone know the mechanics and formulas behind those systems. Specifically the ratios to get the most linear movement to radial movement?
it's a mangle-rack or sometimes reciprocating rack and pinion. I could not find the awser to the other qustion so here is what i calculated hope it's not wrong if we stared whit a tooth size of 0 the angeler movment is ofcorce Pi in radiance before it grips the other side whit tooth sticking out we then have to subtract that then we would have (Pi-2*arccos(r/(r+m)) now tooth height is in the calculation to also take into a count the width (Pi-2*arccos(r/(r+m)-arctan(Sa/(r+m)) where Sa normally is between 0.25*m and 0.6*m and now that we have the angel of the wheel that can be toothed its just the angel*raduis so (Pi-2*arccos(r/(r+m)-arctan(Sa/(r+m))*r (and leve a bit of extra spare room and this is not with profile shift)
Very cool.Mechanical motion is part of how i make my $$$--see motor cycle repair and showcase videos...and it still marvels me after this many years KNOWING that as a Mechanical Engineer on Motorcycles, or cars {All cool vehicles i will fix-vid some] and it is a fact that WE ALL need a Tech! You have a car a bike or a skate board if you cant fix it you need guys like me and others here who can and should get paid for the work of their hands like it says in the good book. God Loves Mechanics!
That already exists. There are a couple manufacturers of oblong chainrings designed to take advantage of the differences in power around the pedal stroke. Rotor Rings is one type that is used by a number of professional cycling teams.

However, I am unable to find photographs of said installation online.
You're right. I have visited that museum and seen them for myself. You can actually turn them yourself with a crank or watch them move electronically

Additionally, this diagonal interface requires the teeth to be "in phase." Meaning you can't just put them in any orientation, the peaks must meet the peaks. Cool effect, but zero commercial application.
These were used in tight confinements where it was impractical for larger gears with the same "larger teeth" could not fit.
Bizzhatesme ??? The diagonal gears take up more space than normal straight gears of the same face width. They serve no purpose other than looking cool.
Wow, it has a big quality considering it was recorded on 1930
How do you thumb this down? Do you not understand it, or is it not cool enough for you? I'm a CNC Machinist, and understanding that without this we wouldn't have a lot of the things everyone holds so dear. Think about it!
Mechanisms are patriarchal.
Patriarchy is oppressive.
Oppression must stop.

Today I learned that there is more than one way of creating reciprocating translation using a rotating input shaft.
Oval gears are used in flow-measurement of fluids. Oval and triangular and other shapes of gears are useful when you want a movement that starts slowly, goes at high spead for the most part and then slows down as you reach an endpoint of some sort. The other types of gears, sprockets etc you may find in for example factory automation where you want to move things in irregular patterns. And of course in clocks.
I don't know why, this just had some kind of dreamy feel to it. Maybe it was the music.
2:02 i'm thinking about mazda
Why?
What is the reciprocating system at 3:45 called? Anyone know the mechanics and formulas behind those systems. Specifically the ratios to get the most linear movement to radial movement?
it's a mangle-rack or sometimes reciprocating rack and pinion. I could not find the awser to the other qustion so here is what i calculated hope it's not wrong if we stared whit a tooth size of 0 the angeler movment is ofcorce Pi in radiance before it grips the other side whit tooth sticking out we then have to subtract that then we would have (Pi-2*arccos(r/(r+m)) now tooth height is in the calculation to also take into a count the width (Pi-2*arccos(r/(r+m)-arctan(Sa/(r+m)) where Sa normally is between 0.25*m and 0.6*m and now that we have the angel of the wheel that can be toothed its just the angel*raduis so (Pi-2*arccos(r/(r+m)-arctan(Sa/(r+m))*r (and leve a bit of extra spare room and this is not with profile shift)
ups it 2*arctan((1/2)*Sa/(r+m)) not arctan(Sa/(r+m))
Bruh, the music is incredible!

I GOT THIS RECOMMENDED TODAY😅.. AND SO DID YOU..
I didn't. Good guess though!
Anyone in october 2020??
Btw..why youtube recommended me this after 11 years!!!???
No

Dante hollow A.K.A the kid in school who everybody replaced it for the most popular and beloved LS engine
Carlo Jaime lizzeni I'm not putting this shit in my engine bay...
Dorito power ftw
Very cool.Mechanical motion is part of how i make my $$$--see motor cycle repair and showcase videos...and it still marvels me after this many years KNOWING that as a Mechanical Engineer on Motorcycles, or cars {All cool vehicles i will fix-vid some] and it is a fact that WE ALL need a Tech! You have a car a bike or a skate board if you cant fix it you need guys like me and others here who can and should get paid for the work of their hands like it says in the good book. God Loves Mechanics!
for some now have found out great fascination of engineering, a must watch for all small boys,this could spark a lifetime in this world.
Sine waves, cosine waves, and Reauleaux Triangles. Ahh, math.
As a licenced aircraft mechanic, we learned the truth of the saying: "You can always tell an Engineer, but you can' t tell them anything!"😉
Could be possible to rearrange the bicycle pedal to pass quickly the ineffective vertical position and focus on downstrokes?
That already exists. There are a couple manufacturers of oblong chainrings designed to take advantage of the differences in power around the pedal stroke. Rotor Rings is one type that is used by a number of professional cycling teams.
hurjaheikki en.wikipedia.org/wiki/Biopace is one of the attempts on this. Biopace resulted in better efficiency and long lasting knee pain.
hurjaheikki Oh yeah, I see what you mean... Nice
Nice to share the classics! :) Very good!
It is awesome, many thanks for sharing!
