GEARLESS POWER TRANSMISSION

[ettorediblasio]

The title is "GEARLESS TRANSMISSION" not "FRICTIONLESS" nor "HIGHTORQUE TRANSMISSION".
Obviously this is a student project.
Stop the criticism.

Use linear bearings in the sleeves. It'll improve frictional losses. And make perfect 90 deg bends in the couplers so that relative motion is point to point traceable.

What is really cool about this, these guys used their imagination and made it into a reality. Weather this device is functionally useful or not is not the point. They, achieved their goal. Super cool.

I must admit it did not look like it would work until he cranked it!

[LazerBee]

I’m impressed! I wonder what would happen if you added more rods, precisely bent, fitted to the bushings and lubricated. Seems like it would smooth out the rotation and make it stronger.

I dont know if they knew this technology existed, there were tasked with making this without "extravagant" tools, time restraints (on the fly ideas), or any other certain restrictions or lack of resources. The fact they were able to make this in general is impressive at minimum. If someone seriously had no idea there was a thing called the combustion engine or electricity, and by themselves made such device under their own knowledge and understanding, or able to ligitimately harness the power of electricity by lightening or making an improvised liquid eletrolyte type battery, who cares if its inefficient or it already exists? THESE are the people that move ideas forward into practice, through know-how. I personally had no idea this type of device was already invented.

Guys they are just students don't judge them too much with your big knowledge

This is a nice solution for the home gamer who doesn’t have a 9, 000 dollar bevel gear cutting mill.
This can be made with a drill and some beer.
Really cool thank you.

All the negative comments here are quite rediculous... this has a lot of applications, currently bevel gears are used for this, which is a very difficult process to make & fit. With your design, you can literally take a couple of rods and bend it and throw in the bearings and it will work. Kudos to you, this is great!

Very intelligent way to transmit power without the use of gears. Well done boys! 👍

I literally watched your video 6 hrs ago and randomly came across a very similar mechanism (that I have no idea how or where I came to possess) while cleaning out my garage this morning. I would never have known what I was looking at here (and i wish I could send u a pic lol ) if it weren't for your very informative and interesting video. Many thanks gentlemen from Detroit.

This is how engineering begins...well done

[reysamson]

If i was your professor i would give you an "A" for creativity and teamwork. Not to mention the team effort you all showed for uniformingly wearing sandals.😀😀

[arnokilianski]

Very cool. The limitations are pretty obvious, but it's still cool.

[SCIENCE-dlgf]

add more L bent straps for getting efficient transmission. well done.

[andrewwilson]

In 50 years of engineering, I have never seen this system in use. I think that it is inefficient and weak, but the principle is good. The design could be improved with better bearings and stronger rods. Interesting project, well done!

[ravip]

Good to see students showing interest in all this because this is the future.

[creativerecycling]

I want to make one! Not for any particular purpose... but, for proof of concept. Stuff like this helps young people think outside the box. Too many schools are only textbook oriented. I learned machine tool technology, not from a textbook, but from apprenticing under an older German master machinist. We had books too, but for reference. I worked under him for 4 years... dirty hands every day... you can’t buy that kind of education!
