What You Need to Know about Spur Gears
Gears are a very important part of any machine. Industries using machines definitely sues gears. When we think of gears, we think of the rotating part of a machine. These gears consist of cut teeth called cogs which mesh with teeth of other gears so that torque or a twisting force is transmitted.
The simplest type of gear is a spur gear and it consists of a cylinder or a disc. This type of gear has straight-edged teeth and aligned parallel to the axis of rotation. This type of gear can rotate together correctly with gears fit to parallel axles.
The designing and manufacturing of spur gears is fairly easy because of its simplicity, and this is also the reason why it is very common and the most used in many industries today. These are very efficient types of gears. When compared with helical gears, the efficiency of spur gears is higher. There is less efficiency in helical gears. It loses power and efficiency because of the sliding contact between their teeth. This motion produce axial thrust which produces more heat.
Using spur gears have many other benefits aside from its simplicity and efficiency. Because their teeth are straight and not angular, designing and constructing spur gears is very simple compared to helical gears. This makes it very easy to design and manufacture. Because of its simplicity, this kind of design does not easily fail or break. You don’t have to spend much in buying and maintaining your spur gears which is also another great advantage. Because it costs less, it gives you great savings.
Spur gears also have their downside. Noise is one thing negative about spur gears especially if they are used at high speeds which makes the entire face engage at once. And this is why spur gears are also called slow speed gears. Power transfer of these gears is only possible between parallel shafts. The transfer of power cannot be done if the shafts are non-parallel. These gears are also not as strong as other types of gears. Since they have small teeth and located parallel to the gear axis rather than situated diagonally as the helical gear teeth are, the load they can handle is not much.
Although using spur gears have their disadvantages the benefits of its simplicity, efficiency and affordability fear outweigh the disadvantages. And these benefits is precisely the reason why spur gears are the most popular gear used in industries and manufactured and sold in markets today. They perform well and meet a lot of requirements of industries today.
