The Merits and Demerits of Spur Gears
The Merits and Demerits of Spur Gears
October 15, 2021

When the word gear is mentioned, spur gears may come to mind. The most common and well-known type of gear, spur gears are the base for any machinery in almost all industries. Made up of multiple teeth that are cut at a 90-degree angle, these gears are great for meshing and transmission. However, they may not be suitable for all operations, for some machines require different power transmissions and efficiency.

 

To know whether spur gears are the right choice for you, it's important to know their pros and cons:

 

Advantages

 

Efficient In Transmission

One of the best features of spur gears is their high transmission efficiency. Thus, for systems that require the almost perfect transmission of power and energy, spur gears are your best bet.

 

Simplistic Design

Due to the perpendicular angle of the teeth and equal spacing between each groove, spur gears are easy to manufacture. Moreover, their design makes them compact in nature and easy to install, making them an integral part of all kinds of complicated machinery.

 

Stable Velocity Ratio

A velocity ratio of a gear is defined by the ratio of the distance moved by a gear due to external input to the distance moved by the load. In some applications where a stable velocity ratio is required, spur gears are the best choice as they have a constant velocity ratio.

 

Fairly Durable

Due to their simplistic design, there is less friction between moving parts, making them fairly durable in nature and dependable for most operations. Examples are the quality gears made by True Gear & Spline Ltd., the leaders in top-notch gear manufacturing and design.

 

Disadvantages

 

Excessive Noise

Since spur gears have to be closely meshed together, they make a significant amount of noise when in operation. This rules out spur gears for many operations where noise reduction is paramount.

 

Limited Stress Tolerance

Spur gears are great for operations where a light or moderate load is exerted. However, they are ill-suited for heavy load-bearing operations and can wear and tear pretty fast if used for such purposes.
