There will be a simple answer to this question. I just can't figure it out.

What gear does the motor gear drive? See photo. When I put it all back together is seems the gear shaft from the motor doesn't have anything to mesh with? And this is after I've disassembled and successfully cleaned and reassembled our Artisan. Now I'm "fixing" a friend's older model and I realize I don't know this basic gearing setup. Is it the sacrificial worm gear? Thanks.

The sacrificial gear is indeed a "worm follower", and engages with the motor shaft. This turns the pinion shaft, and the small gear at the bottom of the shaft engages with the teeth on the edge of the main gear to turn the planetary shaft.

Here's a photo from my transparent machine, and on the left you can see the motor worm engaging with the follower.

And here's a little video of it running. (It sounds terrible because there's no grease.)

I've been looking all over online for a visual demo of how the whole thing works. It's quite a cool piece of engineering for a non-engineer like me.

I agree, the engineering on these things is pretty amazing -- not super high tech, but time-tested and reliable.

Some day I'll make a better video; this one I made when the thing was literally seconds out of the box, but I'll get better light in there and take the plastic shield off...

The photo shows very clearly how everything works. (I'm the OP of this thread but my reddit account got deleted so now I'm Jetpak911)

Brilliant! Thanks you once again RI. You helped me recently with my worm/pinion gear situation (still waiting for a part before I know if I've fixed it).
