Mayday! Mayday!!!

Dear raj,
As I suspected, this building does NOT work. I will try to display a video.
I found that earlier with the four cells model using the crankshaft.

your drawing number three above is wrong and in consequence all other drawings: you have inverted the elbow angle, when in the reality it keeps the bad angle once obtained.

The reason is coming from the bad behavior of the elbow at about 5:00, which must be reversed in view to be preset in the right position for the lift-up in the left side of the wheel.
Only a doubler can oblige this elbow to invert its position.

Nevertheless there is perhaps a solution for an eventual correction: some springs?
For sure, for me, a doubler is the only solution.

Dear Friends,

I have the pleasure to let you all know, that I shall be presenting you all, in the next few days, the BEST of all my gravity wheel designs.

I, unusually, woke up at 4 o'clock this morning, from deep sleep,and hey, presto, out of the blue, came a new idea of my gravity wheel. Something similar to my original gravity wheel, presented here and simulated by Path_Finder.

This new design looks WOW!!!

I can't wait to present it to you all.

I am finding hard to work on my design, during my visit in UK.

Hi everybody!

It is sooner posting than I expected.

So, here it is: The BEST of all my gravity wheel designs.

The drawings below must say it all.

But just for those who can't follow the drawings, I am pleased to explain how the gravity wheel is designed to work.

1. A drum wheel(1) on axle(2), with 8 swinging levers(4)(length of radius) from pivots(3) on outer rim at 45 degrees intervals, starting from the 12 o'clock position of the drum wheel.
2. Eight separate levers (5), (length from pivot to centre of Wheel(1)connected to common fixed horizontal pivot(6) vertically below wheel centre.
3. Eight identical weights(7), each one connected on its axle to one lever(4) and one lever(5), moving in four separate adjoining vertical plains, (as in Path_finder's simulations shown so many times on this thread).
5. In the drawings, the weights are in their starting position, and the the wheel is expected to turn clockwise.

So there you have it.

I, now, await plenty of comments.

Best regards.

Raj

For a start, Assuming CW rotation, look at the difference between the bottom two drawings, and what has to happen in that 45 degrees.

[raj]

Thanks Tarsier79!

That's exactly where the beauty (if any) of this design is.

The wheel is design to rotate clockwise, because the net positive torque in clockwise in the drawings:

The four weights in the four drawings on the left, are spot on the centre of the wheel. Therefore they provide zero torque.

The lowest weight on the lowest drawing on the right cannot move any more downwards and has reached a dead end. It can only move upwards towards the centre of the wheel. The geometry of the wheel design will make sure of this.

The top three weights on the top three drawings on the right, together provide positive clockwise torque, enough to help move the lowest weight on the right, towards the centre of the wheel.

Does the above explanation make sense?

Something for me to savour!

Over four hundred views since my last set of drawings posted in here on 2 Nov.

Plenty of Highly Regarded Members.

Zero comments.

Could there be something good about?

It is sooner than expected, probably to soon!

Raj, if the lower weight cannot fall then your machine is "tube-locked" and will not turn. For it to raise, first it must be prevented from falling and the angle of pull will create more back torque than gained from its fall.

This post is specially for all our Highly Regarded Forum Members!

This is my humble request to you all.
Kindly look at the drawing and my explanation below, and give me your sincere comments.

My explanation:
The drawing below, represents as ONE, the eight drawings I posted on the 2 Nov.

We have a wheel, with eight weights connected/hanging/swinging on eight radius-length length levers at 45 degrees intervals, starting from the 12 o'clock position on the inner rim of the wheel AND on eight levers on fixed pivot as per scaled drawing.

From them, you will appreciate that, on the static drawings, there are five weights, occupying the centre of the wheel. And as such, these five weights do no contribute to any torque producing effects.

The three remaining weights on the right can provide torques to the wheel.
The top two weights hang on pairs of levers that are swinging clockwise, therefore they should provide clockwise torque .
The lowest weight on the right would provide counter torque, as its radius lever tries to move towards the 6 o'clock position.

I, hereby, humbly sollicit your help to work calculate the torque/s by the different weights on this gravity wheel design.

Many thanks.

Raj,
since you asked, I can TRY to understand you, although I guess that you say about '10' and your thinking is '100'.

This last draw shows now to 2 concentric wheels, while other only one.

That previous draw shows that you use a grounded point, so as grounded is the axle. The idea of 'ground' a weight phase looks great to me!

The main weight is added to the wheel's perimeter.

As I could see, in practice and absolutely real, the weight of that elbow itself.

I hope someone else will also comment.

TC!

Raj, the amount of force a weight applies to the wheel is determined purely on how far it falls, or in this case how far you try to lift it. This is common between all wheels, but is not understood by the masses. Lifting the weight like you describe will put a great deal of strain on the levers, and IMO will bring your design to a grinding halt.

You have to decide if your input is greater than your output, then build either your device, or a cut down version of it testing the main parts.

Good luck

Hello everybody!

My apologies if this thread seems to be getting longer.
But everything I have presented here for the past eleven months, are all related, in some way, to my original gravity wheel concept posted on 24 march 2012. See drawing below.

The main problem, with this, my original concept, is the difficulty of achieving the 'Speed Doubler' mechanism for building a proper concept testing model.
All my thanks go to Path_Finder, who is trying his best to find a solution.

[raj]

See below, a similar drawing.

But this time, I have added some levers to the rim of the drum wheel and seesaw like levers, fixed to a horizontal fix pivot, only slightly below the 6 o'clock position of the drum wheel.

These levers are self-explanatory, from the drawing.

The lever at the 9 o'clock position on the wheel, gets hooked on the end of the seesaw lever on the ascending side of the wheel.

Since the drawings show a net clockwise positive torque, by the three weights on the descending side, the hooked levers on the ascending side, will LIFT the lowest weight from its position in drawing 2 right up its new position in drawing 3, thereby forcing the inner smaller wheel to turn 90 degrees clockwise, while the drum wheel turn 45 degrees.
This action, by the hooked levers, does the job of a 'Speed Doubler' mechanism.

My search for a simple 'Speed Doubler' mechanism for my original gravity wheel design, finally COMPLETED.

The drawing below says it all.

Hello everybody!
Please help me resolve the forces acting on the following drawing.

The above are the exact words I started this thread with, in January this year.

As this year is coming to an end, I am bringing this thread to a close, with a happy announcement, that I have, today, formally applied for a patent for my original gravity wheel concept, that has been presented and diversely discussed here throughout the year.

I am, finally, able to work out the forces acting on my drawing! It needed several changes in the drawings to come up with one where the forces can be easily worked out.

Raj

This is specially for Path_Finder, for his dedication for this 'Speed Doubler' concept.

I am reading every one of your posts with utmost interest. I sincerely hope your dedicated effort will pay off one of these days.

Below are two drawings of my new speed doubler mechanism:

See if you can make sense of them!
