Easy Gravity wheel

[JEJEHO]

@Guruji,

That last one I couldn't figure out... but the first design you posted got me wondering... probably won't be a self runner, but I'll have to find some time and play with it, just to see how it behaves, so to speak.

Made a sketch of what I was thinking about... Man, it looks so close...

Thanks for sharing

In Picture 33389627.jpg the hanging weights cant' hang like the picture. Becasue in the L shape hanging weight , the large weight's moment is zero (becasue of the distance from the centre of axis is zero). the small weight has a moment. so it wont hang like shown in the picture. It can hang like ^ this

have you thought of incorporating your idea with the Milosevic principle of dual oscillation?  maybe with a little spring help, you could get it to throw some weight around!

Good morning
I am unfamiliar with that principle can you elaborate?
Thanks

here is a thought.
you need to have a component in your wheel that picks up the weight creating an eccentric load, or else it is not off-balance.  the blue lines I added represent a shelf/platform to take-on/engage the weight during a phase of the rotation.  the radius of this blue line will have to be slightly less than the length of the arm. there will certainly be a horizontal vector from the load back to the pin when the weight engages the blue platform, but it should be small.  some derivative of this idea might create the off-balance condition you seek.

Agreed. For these types of wheels to work negative feedback (ensured by some kind of a ramp) is a must. Finding a way to ensure that with the least friction the biggest drag in this whole research.
