Also known as miter gears, use bevel gears to rotate shafts that are set at an angle to each other. Most often used with shafts that are set at a 90° angle, they can also be used on shafts situated at other angles. Bevel gears have angled teeth and generate both radial and thrust loads on the shafts.
Gears have teeth that mesh as they move against other gears or gear racks to transmit power and motion without slipping. They can be used to change the speed and direction of rotation in a drive system.
