Thanks a lot Murillo .

Hello everybody.

First of all, I wished Ken had applied a friendlier, forget and forgive attitude towards all our forum mambers and stayed among us.

Coming back to my gravity wheel design which Path_Finder has so gracefully animated on this forum for our viewing, I am humbly optimistic that there is someting good about the design.

The only thing left to be done to come to a final conclusuon is to build a working model.

I was hoping to hear from Ralph and A.B. Hammer if they have attempted a build yet or not.

I am trying hard to build myself. But I am having problems at the very start.

No conclusive build and testing of the concept can be done before having a proper 2:1 rpm ratio two wheels built. I have the 2:1wheels model, but they lack proper alignment and precisionsn due to no precision engineering facilities.

In order to bypass this problematic 2:1 rpm ratio wheels on one and the same axle but on seperate hubs as Path_finders animation, I am bringing some changes in the design of the wheels.

See Drawing below:

This time the larger (cylindrical) wheel has a diameter of sixteen units with inner rims of two units diameter.
The smaller wheel has a diameter of eight units with an axle of one unit diameter.

The axle of the smaller whhel rests and rolls on inside inner rims of the larger wheel.

Because the diameter ratio of the inner rims of the larger wheel and the axle of the smaller wheel is 2 to 1, that makes the smaller wheel rotates at twice the speed of the larger wheel when in motion.

The length of the arms pivoting on the outer rim of the larger wheel is eight and a half units and the length of the arms pivoting on the rim of the smaller wheel is four and a half units.

The rest of the design is just like in the original design.

The reason for this new redesigning is to make a built easier, avoiding the need of the very complicated 2:1 wheels gearing system on one axle, to get a 2:1 rpm ratio of the two wheels.

I would be so grateful to Path_Finder, if he could do me a great favour in making a animation of this new design below.

Dear Raj,
I'm ready to make a new animation, but I did not understand well how this new design works. Please give us more explanations. Thanks in advance.

I cannot imagine why nobody though on this before, including myself? It is so simple!...

Dear Path_Finder,
It's so nice to hear from you.

This new design is expected to work in the same way as the original design.

The small inside wheel will be rotating at twice the speed of the larger wheel, except now, the axle of the smaller wheel, resting/rotating on the inside rims of the larger wheel, is vertically half a unit length lower than the axle of the larger wheel.

The movements of the weights are expected to follow roughly the same paths as in your original animation.

Just change the relative dimensions of the wheels' diameter and the length of the long and short arms and positions of the two axles, the smaller wheel below the larger, as explained above.

Dear Raj,

[raj]

Dear Ralph,
I am sorry to be a pest.
I know you are doing your best. It's just that I am a bit impatient by nature.

Here's for you and Path_Finder, my attempt to explain how my new gravity wheel design is expected to work:

1. Assume we have two circles, one of one unit diameter and the other of two units diameter.
The smaller circle rests and rolls inside the larger circle.
See drawing below.
Now the smaller circle represents the AXLE of the smaller wheel and the larger circle represents the INNER RIMS of the larger wheel in my new design.

4. Finally the lateral view of my new gravity wheel design showing how the weights will be positioned inside the drum wheel.
You will notice that there are two vertical compartments, right and left. there will be four weights in each compartment, to allow their easy rotational movements.

I hope my explanations are explicit enough.

I await to hear from you of what you think of this new design.
The only reason for this new design is to alleviate the complicated 2:1 gearing of the two wheels in the original design.

I expect the movements of the weights in this new design will follow roughly the same path as in the original design.

Only an animation of this new design by Path_Finder will prove or disprove my theory.

I await to hear from you both and from other forum members.

Thanks.

Raj

You will appreciate from the drawing above showing the two circles, the amaller one is resting/rolling inside the larger circle.

Because of the larger circle and the smaller circle diameter ratio is 2 to 1, one revolution of the larger circle will make two revolutions of the smaler circle.

This is how this new wheels design is expected to achieve the 2:1 rpm ratio.

Is this explation plausible?

Raj

[path_finder]

Dear raj,
Now your suggestion is clear, and I will build very soon the new animation.
I don't know what will be the new motion after changing the axis position: I'm afraid we will loose the benefit of the balanced geometry and therefore (maybe) reach a keeling position.
Be patient.

[raj]

My dear Path_Finder,
I have a feeling that this new design will work better.
But your animation will surely prove me wrong.

Raj

[path_finder]

Dear raj,
I deeply regret but your latest suggestion is impossible to build, just for basic geometrical reasons, like explained hereafter (see the drawing below).
As required the smaller wheel (in orange) has its axle (in orange) rolling inside a drum (in black/red) with a size twice this axle. This assumes the rotation speed of the smaller wheel (in orange) to be two times quicker than the main wheel (in black/red).
In the showed position (artificially chosen as start position) the attachment pins are A and B for the main wheel, and C and D for the smaller wheel.
The circles in green and red are the requested length for the two rods, the intersection points being where the weight shall be attached to the both rods.
As you can see there is two solutions for the top part of the drawing: one position has been drawn (in light and dark blue).
But unfortunately in the lower part there is no connection point available because the change in the center position of the smaller wheel does not allow any more such as intersection point.
The circles X and Y don't have any common point, as shown in the drawing.
