Bevel gear is one important type of gears. It can take the 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. It is shaped like a right circular cone with most of its tip cut off. They are largely used in the hafts from the main shaft to the back shaft.
With their flexible angles of operation and adjustable force levels, bevel gears are the driving force of many of most commonly used machines. They can be found in a number of different machines such as watches, drills and even some forms of can openers. Besides, we would be unable to drive our cars, fly in helicopters, operate printing presses or do many other mechanical tasks without them.
This type of gear has many advantages which make it so popular in industries. First of all, they have good flexibility. Unlike standard ones, bevel gears have an adjustable angle of operation. It’s easy to tweak their force output by simply changing the number of teeth.
Secondly, they can be made out of a variety of different materials. Metal ones are common in clocks as well as in hand tools such as the handheld drill drivers. However, they can also be made out of plastic or nylon, and they are more common in electronic machines like toys as well as other components.
Thirdly, they not only transfer force from one direction to another, but also increase the force generated after the transfer. 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.
The last one is that they have practical uses. For example, in hand drills, a vertical bevel gear in the handle spins the horizontal bevel gear attached to the chuck. In automobiles, they make it possible for the wheels of the vehicle to spin at different speeds, essential for turning corners.
