Bevel gear pairs
Bevel gears are widely used type of gears that you can find in many -or better to say- all applications you can think of (e.g. automobiles, locomotives, marine applications, priniting devices, power plants, differential drives, robots, and so on and on). As many application bevel gears are used in, as many variations of these gears you can find.
