Everything You Need to Know about Spur Gear


Gear manufacturers produce different sizes and weights of gears. Their applications differ as one gear can be used in one place and not work at other places. Some of them include custom made gears, worm gears and reverse engineering gears as well as the spur and helical gears. But this editorial will focus on the spur gear because of its uniqueness. A spur gear has straight teeth and it is attached to the axis of rotation.

How Spur Gears Work

These gears can be mounted easily when placed close to each other. But the gear needs to be placed in a way that the gear wheels are on the same plane. After rotating the main gear, the teeth available on the primary gear makes the main teeth move forward. Since they are on parallel axis, they make the successive gear to turn and rotate in the opposite direction. If the connection of the teeth is not disrupted, the gear will be in motion as the wheels move.


of Spur Gears

Spur gears can be found in washing machines, clothes dryers and blenders since they can increase and decrease the rotating force. Since they can increase and reduce the speed, they are put in mechanical clocks and egg beaters. Apart from that, they can be found in aircraft engines.

Advantages of Spur Gears

They are built in an artless way because the teeth are on a straight line.More so, they easier to make and does not cause damage. The efficiency of the spur gear is more and it can be calculated by dividing the output power of its shafts by the input power of the shaft multiplied by 100.Since they are easy to construct, buyers can purchase them at an affordable rate.

Types of Spur Gears

There are two kinds of spur gears. The first one is known as the internal gear which is the same as the regular spur gears but the only difference is that their teeth face inward. These gears are also referred to as ring gears.The other kind of spur gear is the external spur gear. Unlike their counterparts, external gears have their teeth cut on the outside surface of the wheel.

Because they are procedures are simple, spur gears can found in industrial and non-industrial places. Since they are very effective and have a high performance, they are used in many industries to meet the needs of many people.
