What You Need to Know about Spur Gears

In any machine, there are gears. 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. In a spur gear, the edge of each tooth is straight 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. 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. There is less efficiency in helical gears. Power and efficiency is lost in helical gears 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. Spur gear are constructed in a very simple way than helical gears because their teeth are straight and not angular. This makes it very easy to design and manufacture. Because of its simplicity, this kind of design does not easily fail or break. They are also very cheap to purchase and to maintain. Using spur gears can give you a lot of savings because they cost less.

There are also certain disadvantages when using spur gears. At certain high speeds, the entire face engages at once and so it makes a lot of noise. This is the reason why they are 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. Spur gears are not able to handle a large load since their teeth are small and locate parallel to the gear axis and not placed diagonally like the teeth of the helical gear are.

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. With spur gears you can expect gears that perform well and whatever requirements that different industries have, they have proven to meet them perfectly.

If you are looking to purchase spur gears for your industry, you can search for spur gear manufacturers in your area and provide for the needs of your industry.
