Those aren't bevel gears, but rather a 4 start worm gear that is pretty high efficiency.
that design was first run by a student on 1425 in the 2007 season and I was very impressed by it. He argued that the efficiency of a single 4-start worm gear is comparable to the 2-4 stages of reduction of lower quality gears most teams use. It was likely still more efficient than many teams.
A worm gear of that style is also easily backdrivable.
