The Ferris Wheel

After over a years worth of work (on and off) I have just completed a scale model of George Ferris Ferris Wheel.Reverse engineered from photographs and books describing how the Wheel was built, it was designed completley in SketchUp and printed on a Prusa i3 MK3S+.It stands 90cm high by 87cm wide and consists of over a 1000 3D printed parts. I had intended for it to move using a motor and you can see the teath on the outer rim of the wheel just like the real one; it rotates freely and the cars all self level but it was just two difficult to motorize it.

Great work! This reminds me a little of our "Riesenrad" in Vienna (Austria).

Impressive.

What is the issue with motorisation?  Perhaps we can help...

Cheerio,

That's because the Viennese Ferris Wheel is, to my knowlede, the 19th century Ferris Wheel which is still around.

Hi, so the issue with turning the wheel was not so much the motor itself... I made a gearbox and motor assembly that turned the wheel but as the two outer rims are slightley out of alignment (not visable to the eye) it wouldnt turn the whole 360 degrees so I had to make a decision to make the wheel again or stick to a static wheel... I stuck to the later decision.

First thought:

You might try a sprung follower on the opposite side to oppose the pressure and keep the drive train in contact. If just the follower isn't enough to maintain the contact, mount the drive train on a pivot and use another spring to push it in place.

Cheerio,

Wow, that is seriously impressive! Amazing attention to detail and faithful to the original ‘Ferris Wheel’ from the 1897 World’s Columbian Exposition (World’s Fair) in Chicago.

Well done!
