My wheel I'm working on

I built a wheel and am testing some of my own ideas. I put a video up Gravity wheel experiment - YouTube , its more less a project in the works.

I'm not really building exactly what you guys are doing. I'm going to try a ramp, then maybe try some magnet repulsion.

I'm using 6 mm one-way bearings. I used 6mm precision drill rod I purchased from Fastenal. The rod is inexpensive. I drilled a hole in the end of my mounting bolts and pressed the rod into the bolt. I drilled out the center of a nut and pressed the one-way bearings into that. I welded nuts onto the bigger nut to accept threaded rod. It was all real easy to build.

You have to be careful not to rotate your one-way bearing assembly too far as the will jam up into the other ones.

Great to see you around

Dusty
IMO,You are one of the great unsung heros of the gravity builds.
Thanks for posting your build.

This one here is a very interesting one indeed..........

When you get a chance if you could give an opinion on this Crazy simple idea over here Perpetual motion?

mostly the floatation aspect? {also do you know anything on Burt Rutans Water wheel?]

You don't have to comment on that forum,maybe a PM or Email

Thank you for the £20 contribution from John received in the post today



Dusty , it's great to have another replicating member onboard, especially since Replicator 1 had to pack everything away because of space and quite a few bent axles.

You have revealed yet another method of moving the weights.


I feel that I have made an important discovery today that no one has talked about.


I made this discovery because I used 1 weight and extended it out using threaded rod as far as I could without hitting the main shaft.

Apart from making a bigger wheel, or using bigger weights, this what I consider to be the greatest improvement I have seen by far.

I am very interested to see one of the existing replicators try this experiment.

Don't be surprised if you find something interesting happen!

As the weight hits the very bottom of its descent it violently kicks the wheel clockwise.

In my case, the kick is enough to make the one way bearings slip because they cannot handle the torque.

What I am suggesting is that a deflection is not needed.

I'm predicting that this device can self sustain rotation using just 1 weight.

The reason why I believe this can happen is because if the variables of weight, arm length, wheel diameter, wheel mass, bearing quality are over a certain threshold, the weight gets into the position centrifugal force does its job and then it continues.

Of course, no useable torque is available because the FREQUENCY is only 1.

I beginning to believe that 32 elements are not needed for "self oscillation mode".

BUT

I believe they were needed for the prototype 10 to work, but not for prototype 11.

I don't think Mikhail is ready to reveal his hand just yet....

I have no reason to think he won't though.

Best regards to all!

Paul

nice

@ Dusty
Enjoyed the video,
You definitley get credit for 32 swing arms! That has been one of the main things slowing me down on my project, and I am still playing from 1 to 4, with nothing spectacular to report. Just getting the feel of different weights and lengths. I like the bike wheel, becuase I have played with them alot in my projects. Unfortunely, if you subject them to too much imbalance, the axles deform quickly and noticeably.
I think maybe I may look for a dirtbike rim or motor cycle rim/ hub assembly for some of my next projects. I liked the bycycle wheel becuase it was easy to aqquire for cheap (10$ US for whole bike at a yard sale). If this device does work, scaling to that tire size would make it easy for many to replicate, even if you had to build several for higher power requirements.
Also don't be afraid to try some of the ideas you think won't work, try everything you can think of.
I like'd your magnet placement ideas also.
@ everyone else,
Good thread and I see alot of good stuff coming up!

Hi everyone!

I do apologise for the delay regarding the group replication build.

There is a lot of good happening in the background, despite the multitude of my failing computer peripherals.



GravInert Research Trust is now live.

The old address still works but I am going to be pushing the new address from now on.

Lots more changes in the pipeline!

Thank you for your patience.

Update 26th January 2013

Hi everyone!


This month has been quite a trial for me. I've had computer hardware and software problems galore, but slowly I'm resolving them.


Whilst experimenting with the longest arms possible I damaged two of the one way bearings because of the torque at the peak of descent.

You can see the effects of this in the video.

Within the next week I'm going to show the same test with the last two working bearings and show the violent centrifugal force at the peak of descent.



I decided to paint the room white to improve the quality of the pictures and videos.

This isn't the best I can do by a very long way, but I appreciate that you good guys have been waiting to see something and it's been over a month.

So here is what I have managed to quickly scramble together.

Conclusion:

The one way bearings cannot not handle the torque.

The are not wide enough to handle the weights and stresses involved.

The one way bearings need upgrading to larger ones.

The knock on effect is so do the axles and shaft collars.

The aluminium weight hangers can be drilled out a few mm.

So the largest upgrade is to 6mm bearings.

Batgold's 6mm bearings look pretty smooth to me in his video.



Great quality one way bearings are key to a design working without motors directly driving the weights.


I think Charlie's design is superior and more tunable than using one way bearings.


I also want to manufacture ONE very heavy duty weight to observe the rotation, gravity, inertia, centrifugal force and torque.

I will prepare some designs to show the new ideas.

My thoughts are that if one weight can overcome the main bearing friction then it looks to me like it will continue to swing.


I also need to post the costs of everything so far.


Thank you all for your patience

Warmest regards,

Paul

Here is the size of the new stainless steel axle for the very heavy 1 weight experiment.




I plan to use a 40mm bar for the hanger, 2x 16mm studs to hang the weight.

3" diameter stainless steel round bar (unless I can find mild steel)

2 x Branded HFL2026 Needle Roller Clutch Type One Way Bearing 20x26x26mm Simply Bearings Ltd


The hole will be drilled out in the wheel to 10mm and a titanium bolt hold the axle.


This means potentially 4 elements with full size swing arms could fit on each side of the wheel with a frequency of 8.


As many wheels as possible could be added if the shaft was extended all at different degree fixings to increase the frequency.


However I still believe that 32 was only crucial to Mikhail's prototype 10.

I believe this experiment is the best way of proving my theory.


I'm working on trying to capture some slow motion of the video I posted. Hopefully it works out.

I was using an iphone 4S to film so it is never going to be brilliant.


I'm going to have a chat with The Slo Mo Guys and see if we can find a way forward.

The video is great!
Well, congratulations!

2 bad the bearings couldn't handle the stress. Can't wait to see the new improvements!

Also i have one suggestion.

The rotation due to deflection of weights_2. Gravity wheel. - YouTube

In this video we can see the small motor pushing the weights. It seems a conventional motor, nothing special.

But what if!!!
Instead of that you would use a magnipulsion engine?
The energy required to push the weights would be highly decreased and the gain from the system would be even higher.

Hi Paul,
I have been to GravInert, registered & received confirmation by my E mail. But when I try to log on, a invalid comes up so I can't post. I also did not see a place for donations. Not to long ago you posted a link to (I think) paypal where I could donate with a visa debit card, I acquired one of these just for this project. I can't find the post with the link. I will look some more.
I hope the larger bearings work out.

Regards, Gene

Hi TheVisitorV,

Thank you for the suggeestion, I will study the link you provided.

You may have missed it earlier in the thread.

This is the video Mikhail never posted to youtube:

https://www.dropbox.com/s/6l1cojripb...deflects.mp4?m

The amount of weight used 32 x 6kg = 192kg plus the rest of the wheel, TOTAL 250kg

Once a certain speed was reached, the wheel ran with no external input apart from inertia, centrifugal force and gravity.

This is why Mikhail changed direction from Gravitational Engine to GravInert.

He wasn't expecting this phenomena to happen without the deflecting wheel.

Prototype 11 was built very well using quality one way bearings.

You may have read earlier in the thread that after the video was stopped the chain from the generator snapped and the wheel accelerated further. Mikhail mildly injured his hand whilst stopping the wheel.


I am aiming for using the three invisible forces and one way bearings or just the three forces, normal bearings and a guiding track. If that can be done.

It is an amazing project.

Thanks for your input.

All the best,

Paul

Hi Gene, to help pin point the problem are you trying to log in at

GravInert Research Trust

or

GravInert Research Trust ?



I am paying particular attention to the maximum torque the one way bearings can handle from now on.


I will sort out a button for donating to the group build hopefully tomorrow.

Thank you for your support!

Best regards,

Paul

I thought it would be good for everone to see a comparison of the bearing size, torque and cost.

Update 26th January 2013

I think Charlie's design is superior and more tunable than using one way bearings.

I also want to manufacture ONE very heavy duty weight to observe the rotation, gravity, inertia, centrifugal force and torque.

Aw shucks .....stop it Paul your embarrassing me!

Actually there is one additional force that we may have overlooked and that is the concept of velocity and momentum.

Think about throwing a ball to someone using an 'underhand' throw. If your arm was simply hung straight down and you threw the ball it would only go so far. But when you bring your arm back and down through a full swing, it would go much further.

If we relate this to what's happening here, it would follow that there would be a distinct advantage to propelling the weight at the top of the rotation as opposed to simply waiting for the centripetal force to move the weight out.

That is what I will be testing with my setup. My original thought was to move the weight fully in (180 degrees) at the bottom of the rotation to take advantage of the maximum over-balance, but now I'm thinking that 90 degrees might actually work better. This would leave the weight arm perpendicular to the main arm and allow for the maximum velocity and momentum when propelled at the top of the rotation.

Regards,
Charlie

[soundiceuk]

Fantastic observation Charlie, hey you might be onto something there!

I hadn't even considered these forces.....

This really is many invisible forces combined!!!



Hey, does anyone know where Charlie could obtain any tasty motors like used in these:

Check out the specifications! Dribble, dribble

CT6850, 18V Cordless Impact Wrench (U.S.)

I used to own one of these 18v impact wrenches.

I snapped a wheel nut with it. It was very powerful.

They also run off rechargable lithium ion batteries as well as nickel cadmium.

Cheers,

Paul
