What makes something have dog engagement box is how the purple gear above engages with the blue gears. The straight cut, or helical part of the gear box is how the blue gears engage with the red gears.

EDIT: Hah, I didn't realize Scott posted the same link too. We were just talking about it like 5 minutes ago too
