I started questioning what I put up afterwards. I was ignoring too much about what forces the torque creates in the gear tooth. I dug out an old text book and this is how it says to analyze forces in gears. The gears have these forces F and the Reactions R. The angle F is at depends on the pressure angle of the gears. That makes our gear drive look like this. Breaking out the idler gear. It looks like the two reactions R would add together to a vector pointing to the right and up. But that amount depends a lot on the pressure angle. If you had enough pressure angle, the two forces and reactions could completely cancel each other out.
