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. 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 basic type of gear is a spur gear which is made up of a cylinder or a disc. This type of gear has straight-edged teeth and aligned parallel to the axis of rotation. Gears fit to parallel axles can rotate together correctly with this type of gear.
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. These types of gears are also very efficient. Their efficiency is higher than other types of gears especially the helical gears. Helical gears are less efficient. Since their teeth have sliding contact, it loses power and efficiency. This motion produce axial thrust which produces more heat.
Aside from the benefits mentioned above, there are other benefits to using spur gears. Spur gear are constructed in a very simple way than helical gears because their teeth are straight and not angular. It is not a complicated thing to design and manufacture spur gears. This design also does not break easily or fail easily. They are also very cheap to purchase and to maintain. 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. 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. They perform well and meet a lot of requirements of industries today.
