Did anyone else notice that the gear ratio changes as those non-circular gears turn? That means if you turn one at a constant speed the other one will speed up and slow down as it goes around. That might be useful for something.
+Warren NZ Shimano BioPace(and others) bicycle sprockets have been made like that for years. It allows for different torque to the back wheel depending on your leg/crank position.
Exactly my thoughts. Example #2 demonstration. Could it somehow be used in an internally geared rear hub for a bicycle drive to magnify the "osymetric" effect/affect? Or, perhaps, even in the crank as the original osymetric is? I would think so. Have not the energy or patients to design develop patent this, but could be worth millions.
Meh, they know calculus and can figure it out, or they can simulate or experimentally determine the result to whatever degree of precision they need for a given task.
The only problem with these gears is the potential for wear due to the abruptness of some of the changes. At slower speeds the impacts aren't too bad, as long as they aren't carrying a big load, but higher speeds and higher loads could cause them to wear faster
If you mean, do these things have a practical application? You're right, probably not. But I think they would make good problem solving toys for children. Just give them the box of pieces and let them figure them out.
As a mechanical engineering student, I need to note: as long as the teeth match and the distance from rotating point to the tooth of one gear and the other add up to the distance between the pivots it works. The bits without teeth need to meet about the same criteria (matching shape and distance) and at a constant rpm those are used for timing.
This is epic! You should have your work 3d modeled so you can then sell it as digital download for 3d printers. Would make for some epic dynamic home decor!
I like how this shows off how simple and yet complex engineering can be. Simple in you just need a consistent contact point, and complex in establishing that contact point.
All you folks are missing the point. While it is true that some of these gear trains are just novelties, take a look at the motion of many of the output gears, relative to the motion of the input gears. See that? They represent a mathematical function, depending on the form of the gears. As an example the Norden Bombsight, which was one of the great secrets of WW II, had many such eccentric gears within it, which performed all sorts of math operations
What an eye opener! Your creations should be in a book for money. They show the generality of how gears need interlock, like I could totally see mechanical engineers learning from this in class.
I like these gears. Up until 4:00 it seems that most of them are either "perfect" geometric figures or figures where one was cut as the complement of the other -- if you decide on a given distance between the two gear axes then, given one gear, the other needs to be made into the complementary radial function of the first. Adding more gears seems like an interesting problem too, as well as letting certain portions slip, like with the fish gear. The inner gears at 4:00 are all the same diameter for this reason -- I imagine they can be placed anywhere in the interior space and it would still work out. Cool!
I like all the gears, This video got my attention... I have a great respect for the person who made this gears... Hope the students get some knowledge from the video. God bless...

Q: What's the gear ratio?
A: It's complicated
especially on the last ine
no its not That is called a planetary gear its in every automatic transmission
Or torsen differential...

You can still calculate ratios with teeth.

No professer would say it’s speed is proportional to its size...
Actually you mix up the meaning of rack-wheel with gear. Here it's not a wheel, that's all.
Ok imagine using these funky gears specifically to tick off normal engineers just trying to figure out the gear ratio.
Juste count the teeth
Non constant speed can be a problem tho

NWViewer1 The one at 1:43 (or very similar gears) are actually used a lot in things like mechanical calculators and clocks.
Great youtube comment.
Some of these gears also make a push and pull that could be used for a piston
The one at about 1:40 is actually used by old scool movie projectors.
The one at 4:10 is used somewhat simular in automatic gearboxes.
