Bevel gears:
space saving and highly efficient
Like the worm gear, the bevel gear also produces a 90° redirection of power. This type of gear does, however, have the distinct advantage that it produces a much higher effectiveness due to the high gear ratio. As these gears produce hardly any inherent heat, bevel gears can also be designed much smaller. Apart from in general industrial applications these gears are often used in differential gears.
