Any discussion of Bevel Gear Boxes must first clarify the definition of Beveled Gears.
A bevel gear is made in the shape of a cone. Deployed in pairs, they are used to connect intersecting shafts. Normally they are mounted on shafts that are at 90º to each other (hence the term "right angle" bevel gears). However, they are not restricted to 90º mounting.
