So apparently for a certain gear characteristics, there is a (or number of teeth you can have on a gear (or minimum gear size) that you can have before it no longer meshes properly becomes too much like a star or cross shape and deviates too far from that of a circle (in layman's terms).
A bunch of the papers I've been reading say that the minimum gear teeth is 12-13 (For the gears they were looking at) and that seems to hold up for the most part at the pinion gears for RC vehicles...except you sometimes find 10T, 9T...all the way down to 6T pinion gears.
Are these pinions sacrificing proper meshing for higher gear reductions? Because gear tooth profiles are pretty standardized and since these pinions must work with existing gears, nothing can be done to either driven or driving gear to get them to mesh better.
Like look at this:
**broken link removed**
it barely looks like it would mesh with anything, being star-shaped and all. A whopping 60 degrees between each tooth! I might be able to barely visualize 45 degrees like on an 8-tooth pinion, but 60?!
