What You Need to Know about Spur Gears

In any machine, there are gears. Gears are very much used in different industries. Gears are those parts of a machine that turns or rotates. We have all probably seen how gears work; these gears have teeth and when the teeth comes together it creates a twisting force or a torque which helps the machine to operate well.

The simplest type of gear is a spur gear and it consists of a cylinder or a disc. The spur gear is a type of gear where the edge of each tooth is straight and aligned parallel to the axis of rotation. The spur gear can rotate together accurately with other gears fit to parallel axles.

Spur gears are very easy to design and manufacture and this is the reason why it has become the most common type of gear that are often used in many industries. One good thing about spur gears is that they are very efficient types of gears. When compared with helical gears, the efficiency of spur gears is higher. Helical gears are less efficient. Power and efficiency is lost in helical gears because of the sliding contact between their teeth. When this happens, axial thrust is produced which produces more heat.

There are other advantages to using spur gears aside from their simplicity and efficiency. Because their teeth are straight and not angular, designing and constructing spur gears is very simple compared to helical gears. Designing and manufacturing spur gears is very easy. This design also does not break easily or fail easily. Another good thing about spur gears is that buying and maintaining them is not costly. With spur gears, you have more savings because it costs less.

There are also certain disadvantages when using spur gears. 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. When it comes to strength, spur gears are not the best. 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.

Using spur gears have many advantages like its simplicity, efficiency, and affordability and the disadvantages will be as nothing with these benefits. 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.

You can benefit much from the use of spur gears which you can buy from leading gear manufacturers in the country.
