Two arms...
« on: October 19, 2010, 04:08:50 PM »

  .....or a first degree lever,in my opinion ,can be the least configuration ,of a possible gravity motor ,IF  we play :

      -two masses

      -a fixed arm

      -a variable arm (so to realize,alternately,a greater/smaller torque than the opposite/fixed arm ).

        All the best ! / Alex

.....first line design,is an attempt, so that everything can be made as simple as possible,on paper firstly,and in reality chiefly...

     As a fact of matter,the problem is reduced from "two arms" to that of a "single (variable) arm".

     All that we need, is to imagine and test,a continuous unbalance (greater torque due to gravity), on the same side of the fulcrum.

     Now,the small step remains to get the self-unbalancing...self-acting.

        All the best! / Alex

That motion is from the popular science 1910 fair in chicago. Mikhail Dmitriev made 2kw devices from a wheel like that, 8 feet high with a bunch of Shifting weights pushed by a bike wheel, not difficult. Self looped.

But you must input the power following this concept if you want to drive something, not just having it move around forever, even tho that is pretty cool.

here is another unrelated  video, he simply locks in the gear, what happens to a machine that  tries to synchronise to a gear at high speeds ? Not sure, needs to controlled by microcontroller the  entry drive must be good. Nevertheless, good concept.

Here is a variation of this concept I have in mind, more elements is always better, but you get the idea.

see this sketch .

Interesting,
very interesting.
Can you please elaborate more?

Research the teachings of Mikhail Dimitriev.

For your curiosity, Chalkalis has a self rotating design (undriven) as per the 1910 shape, very particular since his arms are ammovible.

There are many ingenious, and sometimes efficient ways to get energy from this concept.

But be warned, Peter Lindemann says not to get involved with him, and your hard built machine will be confiscated if you dont shut up. ;D

I forgot to mention, the brown wheel in my drawing should be a freerunning clutch system so that the drag is avoided.

Can you please explain how exactly your system works - I have difficulties visualizing it.

I think I more or less understand what Dimitriev talks about:
a very small torque can create a significant moment of inertia of the wheel
since the input torque is constant, but the MoI is proportional to the square of the rpm and the mass.
At certain point the energy expenditure of the input may get smaller than the output due to above
dependencies (with the emphasys on may)

The idea I put forward, relies on moving the motor, along with its freerunning contact wheel attached the motors shaft . This motor drives itself intelligently along a circular metal loop wich is attached to the main frame. You can also do it the other way around, outside drive and friction wheel inside rollercoster like.

The more of these elements the better, inverted weight distribution and pair number alongside the main frame.

Connections, electrical and mechanical, are omitted.

So it transmits the impulse to main wheel it is attached to at the point when it flips from left to right?
Have I understood this correctly or you envisioned it differently?

...let's say a continuous variable/oscillatory leverage , with two masses ( stabile+mobile...) , playing gravity and inertia , at :  www.youtube.com/watch?v=N6G5aC9BtSc
You can take it as a suggestion , so to replace the circus performer with the most simple " thing "...and obtain self-running motion.

If you had, this motor, mechanically coupled to the output.

You would be making a positive feedback loop.

Eventually it would break if left like this , that is a certainty.

You can also reflect back the weight inwards, but that sytem would geat a beating.
