General stuff / Re: worm-drive

this is designed to use bearings for the teeth so that the resistance created on the face is very very small.
I also did this using 2 slightly offset grooves and 2 bearings per so that one bearing was in contact with one face and the other bearing was in contact with the face on the other side, I did that so that I could make it a zero back-lash setup.

This one also works well both ways, that is turn the larger gear and it turns the smaller one or turn the smaller one and it turns the larger one, even at some steep angles

Having a small issue with not being able to upload a 35m file that is a .mov of the thing working to spin the upper half one way and the lower half the other way.

a single one sided groove so the path can be seen

This is a little petty maybe but I want my test-part to use a different storage potential than the test-bed.  The test-bed uses CP as the storage medium for work transfer and it looks like I can do something similar with the test-part but I want it to do things differently.

If I look at the "how" that may work and then look at what I thought the test-bed was doing,, well I might of over-thought the "how" for the test-bed.

I can add any number of sources to the slack side so long as the added force into the belt\chain is in the same direction, it would not be a source if it were not in the same direction.

To make or impart any FORCE there must be a force of opposition, an output if you will, or a sink.  This point of opposition then determines the tension side and slack side and if the system were closed upon itself, like a belt or chain usually is, then I can instantly change where the slack and tension sides are, source and sink.

I can also have any number of outputs ,and as it should be the output(s) must equal the input(s).  Any force potential that is not used by one of the outputs is passed through to another output that may be at any point along the path of the belt\chain.

Since force does not have a velocity or a distance then the modality of how the force is manifested does not matter.  In the real world you just can not have your sources run through, physically, any other part.

So the belt\chain then, in a sense, becomes a storage medium for potential similar to momentum  and how that potential is depleted is how the work is performed.

another note; a belt and pulley or a chain and sprocket are one-way force transfer devices.  You can not transfer any force on the slack side of the belt\chain.  You can MAKE and external constraint system to allow you to transfer a push for either but by themselves they can only transfer a pull.

just as a note; I am using gravity as a source, BUT, I have to supply both the motive force and the force of opposition, both of these are courtesy of gravity.
