One of the most vital parts of any machines is the gear. Basically, they are wheels with specialized teeth that move one shaft to also move the other. One of the common types of gear used in mechanical products is the spur gears. They are cylindrical in shape that have spindles and runs parallel to the axis of its rotation. These gears are usually the first choice when choosing gears. In fact, they can be found in most objects of any kind, ranging from wind up alarm clocks to electric screwdrivers. They ensure that the tools and equipment you use every day operate smoothly.
Technically, spur gears are ideal to either reduce or increase speed, improve accuracy for positioning systems, and magnify torque. When the teeth of these gears collide, a loud noise is created. In terms of design, the gears are compact and are very easy to install while providing a constant velocity ratio. This feature is important in preventing erratic torque distribution. In effect, therefore, spur gears are highly reliable in performance and delivery. Moreover, they require less maintenance and cleaning would be enough to avoid issues such as teeth becoming brittle. Additionally, the fact that the specific construction of a spur gear allows it to be an efficient conduit of power.
Spur gears can be made using a wide variety of materials depending on their application. Some of the common materials used to manufacture them are cast iron, alloy steel, cast steel, aluminum, carbon steel, brass, copper, and plastic. The major drawback when using spur gear is that the pieces have to mesh together at all times since they have to be in contact with one another to deliver their task. This results in friction that creates heat and sound, generating high ambient noise. The friction also causes the splines to go through great stress when it comes to heat generation and weight over time. Yet, overall, the long-term reliability and consistency of spur gears make it stand out from other kinds of gear design available.
