Bevel Gear Advantages

• Bevel gears are found in a number of different machines, including watches, drills and even some forms of can openers. These gears take the force from one direction and change it to another direction, often creating additional, beneficial changes to the force as it's transferred along.

Direction

• Bevel gears can take force from one direction and change it to another direction. For instance, force from a drill that comes in horizontally can be changed to a vertical force with the use of a bevel gear. This can be quite useful for the chuck in a hand dril, because it allows the force generated by the motor to push the drill bit at a convenient direction. Bevel gears are also what lets the chuck open up on a hand drill so that bits can be exchanged.

Force

• Bevel gears not only transfer force from one direction to another, but they can also increase the force generated after the transfer. According to Technology Student, when the initial gear moves, turning the bevel gears, the force goes up after the transfer process. This can allow a relatively weak power source to generate a much stronger output of energy through the proper use of bevel gears in the power assembly.

Materials

• Bevel gears can be made out of a variety of different materials. Metal bevel gears are common in clocks as well as in hand tools such as the handheld drill drivers already mentioned. However, bevel gears can also be made out of plastic or nylon, and these types of gears are more common in electronic machines like toys as well as other components. The lack of metal means that the bevel gears can function properly without conducting electricity and damaging the machine.
