Hi raj, could you show an end elevation view please.

[raj]

Hello OldNick.

I don't quite undersstand what you mean by 'an end elevation view'.

If you mean the highest vertical point a weight passes, it is just above the lower (inner) wheel hub when this weight hangs/swings on the rigid lever (in red ink) from the 12 o'clock position on rim of the lower inner wheel ( in red ink) and the flexible cord at the 6 o'clock position upper ( inner rim) wheel ( in black ink) which is, by now, completely slack.

I WISH I could do a 3D drawing and better still, if I could do a full compter simulation.

A concept testing prototpye WILL BE attempted in due course.

Hi raj, end elevation is a view looking from the left of your drawing, we would see the edge of your wheels and the positions of your axles.

[raj]

Hello OldNick,

The drawing below is the best I could do.

It shows how my Gravity Wheel concept testing prototype will look like, using two bicycle rear wheel hubs and axles, (in black and red ink) fixed on opposite fix stands (in brown ink) on one ends and geared in 1:1 ratio by belt (in green ink), making sure that larger outer wheel with broken radius(arms) representing its inner rim on black hub and inner lower wheel, represented by diametrical arms on red hub, rotate at the same speed/rpm.

Two weights (in blue ink) swing/hang
(a) one close/below the lower wheel hub on rigid arm pivoting on rim of lower wheel at the 6 o'clock position and on stretched flexible cord connected to broken radius arm/inner rim at the 12 o'clock position.
(b) one close above the lower wheel hub on rigid arm pivoting on rim of lower wheel at the 12 o'clock position and on slack flexible cord connected to broken radius arm/inner rim at the 6 o'clock position.

I hope this answers your querry.

I hope you will all appreciate that my gravity wheel concept testing prototype will be a bi-directional wheel attempt.

Moreover, My gravity wheel concept testing prototype does not need to have ANY RIM

In fact, my expected gravity wheel prototype WILL NOT be a WHEEL in the sense of the word we all know, 1.e a continous circular figure, that can roll on a flat surface.

Hopefully I shall be attempting to build my gravity wheel concept testing prototype next month.

In the meantime, I am continuing to present drawings and explanations of the expected workings of my concept.

Only for those who care to know and appreciate my concept:

Four pairs of weights, representing eight weights expected motion/positions, connected to inner rim of outer larger wheel and inner wheel.

Torques calculations become so much easier.

Raj, I like you a lot as you literally don't stop thinking, and it is that ability to conceptualise that separates us out from lower mammals.

Dear Chris,

I learnt something from you this week, something I have been striving to achieve but I never mentioned it on this forum.

Your '' Fluidity of weights motion'' advice on your own thread, is the FIRST requirement of a successful working wheel.

That should NEGATE friction to minimum.

The other vital requirement, according to my logics, is that the complete wheel system with every parts inside should be lightest as pssible, because the whole lots rest and rotate on the axle/s, where the friction should be minimised.

Only the mass of the weights should be maximal, because the weights that provide torque.

In my own concept design, I see fluidity in my weights motion, as and when wheels would rotate.

The weights hang/swing on the rims of wheels on the descending side and rest (as parts of the wheels) on the ascending side, with ZERO friction.

The only friction my concept has to overcome is on the axle bearings.
I am planning to build my concept testing prototype wheel lightest as possible, WITHOUT Rims.

I am expecting the net positive torque by the motion of the weights would be sufficient to counter the friction on the axles and turn the wheels.

The motion of 070715-001 reminds me of an ancient animation:

[Triplock Jnr]

Raj,
I'm glad that you picked up on my comment about fluid motion of any internal weights as it is my contention that there are several methods or principles that can induce self sustaining rotation to a 'wheel'.

In the high rpm versions , to avoid lag, the method requires the continuous, effortless movement of attached weights , such that they never come to rest or impact stops etc. there must be no begining or end travel such is the case when a lever falls or resets upon inversion.

I will show my take on a gravity equalised motion wheel on my other thread.

However Raj your interconnected flailing weighted 'sticks' do have merit and some advantages of you prefer the OB route.

Chris

[raj]

Thanks a lot Me!

If the weight, in the animation, on the ascending side of the wheel would take a path closer to the axle between 6 o'clock and 9 oclock positions, this could be a better design, assuring continuous net positive torque for continuous rotation.

It will be then identical, in workings, to my own concept.

Raj

[ME]

Yeah well, that 10 year old blast-from-the-past thing in my animation doesn't work.. Going left or right does not help.

I hope you have a better solution - you have two radii up/down for instance (I'm not sure what to make of it yet)

[raj]

TIMIDLY attempting concept testing:

Here is the smaller INNER wheel with one pair of the four pairs of diametrical spokes of the wheel (without any rim).
