Understanding Spur Gears and Its Advantages
In any machine, there are gears. Almost all industries use gears in their operations of machines. Gears are those parts of a machine that turns or rotates. 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 spur gear is the simplest type of gear consisting 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. 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. 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. With spur gears, you have more savings because it costs less.
Spur gears also have their downside. At certain high speeds, the entire face engages at once and so it makes a lot of noise. And this is why spur gears are also called slow speed gears. You can only use the spur gears to transfer power between parallel shafts. They cannot transfer power to non-parallel shafts. These gears are also not as strong as other types of gears. The load that they can handle is not much since their teeth are small and located parallel to the gear axis rather than situated diagonally as the helical gear teeth are.
Using spur gears have many advantages like its simplicity, efficiency, and affordability and the disadvantages will be as nothing with these benefits. And this has made spur gears that most popular type of gear being used in the market today. They perform well and meet a lot of requirements of industries today.
