That's pretty much how it does work, although each "step" of the transport protein requires ATP to bind and lose an inorganic phosphate. This is how all vesicles are moved within cells; literally hundreds of millions every minute.

The "feet" of the transport protein are electrochemically attracted to the cytoskeleton protein it is walking on, somewhat like a magnetic attraction.

Rapid ATP loss caused by methamphetamine in the mouse striatum: relationship between energy impairment and dopaminergic neurotoxicity.
Chan P1, Di Monte DA, Luo JJ, DeLanney LE, Irwin I, Langston JW.
Author information
Abstract

To study the relationship between energy impairment and the effects of d-methamphetamine (METH) on dopaminergic neurons, ATP and dopamine levels were measured in the brain of C57BL/6 mice treated with either a single or four injections of METH (10 mg/kg, i.p.) at 2-h intervals. Neither striatal ATP nor dopamine concentrations changed after a single injection of METH, but both were significantly decreased 1.5 h after the multiple-dose regimen. The effects of METH on ATP levels appear to be selective for the striatum, as ATP concentrations were not affected in the cerebellar cortex and hippocampus after either a single or multiple injections of METH. In a second set of experiments, an intraperitoneal injection of 2-deoxyglucose (2-DG; 1 g/kg), an inhibitor of glucose uptake and utilization, was given 30 min before the third and fourth injections of METH. 2-DG significantly potentiated METH-induced striatal ATP loss at 1.5 h and dopamine depletions at 1.5 h and 1 week. These results indicate that a toxic regimen of METH selectively causes striatal energy impairment and raise the possibility that perturbations of energy metabolism play a role in METH-induced dopaminergic neurotoxicity.

It's a chemical reaction that's favored to proceed along the chain below. It's like a domino effect, it's encouraged to proceed along the path of least resistance.

It would push itself apart.

I was thinking of creating a circular T slot in the face of the gear so it can be held up by poles or something and allow it spinning and support any other moments.

Or making an insert that holds up the neighbouring gears.

I would go with the insert, easier lubrication and its simple to construct.
The T-slot needs to be solid and big enough to withstand the torque and it would make the ears bigger. Also it would be harder to assemble

While your not wrong, I think what the other anon was getting at was that the heat is being generated by the metal's molecules/ions. Sure, the current is transferring energy to the ions, making them vibrate and "rub" against each other (kind of like friction), so you could view it as the current causing heat. But you could also look at it as the current transferring energy to the metal, and due to the metals properties the heat is generated.
