a wheel model using 2 full curve
http://youtu.be/y2EhDPqiEi0




yap, that design does give mi problem, so revert back to traditional design.

  helloha, this is something that some of us have wondered about. If the balls
could roll from the inner curve of the wheel to the other side on it's outer curve.
 Then after rotating the wheel, it rolls back to the other side of the wheel and up
it's inner curve again. It might take a ramp next to the wheel for the bearing to
roll on, but the lift and drop would be close, and the ball on the outer curve
would have more leverage.
 
edited to add; helloha, do you think you could have the parts where the arrows pointed roated
a little bit in those directions ? Basically, just showing the curved part touching the outer wheel and the
weight and it's lever dropping a little.

Isn't the idea the sjack abeling wheel? Jim, u bad bad, i visualize myself getting into trouble, NOOOO..... :(

anyway, about the ball rolling onto the ramp, u can take reference from past cg i done here
http://youtu.be/1VIYHqRD-Wg
http://youtu.be/Jm8yPyUq7CE
timing is the issue, the ball either will roll to ramp early or late, but never what i expect, and landing on the other side.......sign  :'(

but i will be implementing the ramp idea to the rollback wheel, just need to think alot, and trial and error alotttt, but lets take a break first.

The CG in the photos in post 31 seems like it would be below the axle. Great mechanics but bad CG so it probably bottom heavy.

  I swear you are a magician helloha. I have done a lot of trial and error myself. Half the fun is trying something.
@Norman, the idea is to pump water with these mechanics. When the weighted lever closes the bottom of the curved pump, water is moved upwards. While helloha shows the pump closed, depending on the placement of the short lever, that could be how it works. And that is a detail that might take some trial and error to learn the proper placement of the short levers.

   helloha,
 What might be a thought is something close to what you have been trying.
 If 4 weights are on the over balanced side and 3 are in the inner under balanced side, there might be a way to get it to work (or almost).
 The 4 weights on the over balanced side would be on a round cylinder like what you have been trying, They can be spaced going deeper into the wheel and as the wheel rotates, they move towards the front and a ramp.
 When they roll into the inner circle or wheel, there are grooves like the threads on a  bolt that push them up a ramp going deeper into the wheel.
 This would allow for more weights working than being lifted, in theory anyway.

  helloha,
if you want to try something that might interest you, try over lapping
2 circles and have them rotate in opposite directions.
 If you have them over lap at 45 degrees from bottom center, that point would move straight up if there was a slide between the 2 points.
 This would mean that the opposite point of either circle should have more potential when moving from 45 degrees from top center to 45 degrees before bottom center.

                                                                                                                            Jim

at first thought inserting just a ramp should be fast and easy, but no, end up have to adjust almost all the internal structure of the wheel, then have to trial and error to get the timing for the ball rolling off the ramp right....  :'( .... need to rest

the idea on opposite direction is a very good one, try first test but got problem (think its a software bug, anyway its complex, alot of headache), give up

  I'll post a drawing tomorrow helloha. not sure how doable it will be but should give everyone the idea.

  helloha,
 in this example, the distance from center line or axle to center of mass for the weight on the left is a distance of 1 (1 meter, 100%)
and is lettered A. With B, the distance is .7 (70 cm's or 70%) of A. The difficult part would be to transfer the force of the weight from
1 wheel to both wheels and then back to one wheel.
 The line B would have half of the weight's mass on each wheel while it is being lifted straight up. Not sure how it could be put into
a working concept if it is possible. i have bought wood to make a routing table so I can start work on the 4 weighted wheel you modeled for me.
I'll be making it with 8 weights and will be building 2 different wheels. The wheels will use the same basic principle but one will have more detail allowing it to work faster (hopefully). Not sure how long those will take to make.

                                                                                                                                      Jim
p.s. what might be an idea is to have the weight move from one wheel to the other and do a figure 8. but 2 weights should suffice.

edited to add; may consider a 4 weighted wheel trying to replicate the model you posted a few posts back. think it would be kind of cool to
show that your modeling does help that much and to see how close they actually look when compared to each other.

extend a longer path for the descending weight, but due to poor design (or maybe just impossible), simulation failed, obviously.
will hold on the remodel of the wheel till next year, then maybe redo.

  helloha,
 Once again, a cool design. Not a poor design, just a difficult challenge.

extending an even longer ramp length.

althought the simulation is an unsuccess one (maybe because i'm too lazy to go through the phase of trial & error, tweaking & tuning  ;D ), but still it's a good presentation on the drawback of using ramp.

To all, merry christmas and a happy new year  ;D

...


first try on magnet idea on wheel

http://youtu.be/6XUFDV5nWng

this cg is presented only on wireframe view, as i used an older model of wheel, below the link

http://youtu.be/UOLPuvsXe9I

trying to simulate the action of magnet repel force on the weights by using wind force (as the simulation program do not have magnet feature, so have to make do with wind).

but the wind option does have its cons. although it can set its range, but all the area within the range will be affected by the wind. also both the weights and the wheel are influenced by the wind (only the weights should be, in the case,for magnet).

no change on wheel, focus on the interior structure of  the weight (ball or sphere). The weight is made up of an inner core and outer core, where the inner core is heavier than the outer by 2:1 ratio (depend on individual setting)

the modified weight seem to have a faster reaction speed, but overall for the wheel, don't seem to have much improvement.

the link for the wheel model http://youtu.be/FLxQDlD9Gzw

and interesting reference for the wheel/weight http://www.youtube.com/watch?v=yAWLLo5cyfE  (prefer this conceptual physics because of minimum math involved, as i almost totally don't understand math equation)
