Quoted for truth: It may not be obvious unless you have studied gears, but the teeth if an involute gear don't just push on each other, they actually ROLL across each other. The sliding action (which leads to wear and wants a lubricant) is almost zero. That's one of the reasons center-to-center distances are so very important for gearboxes.
