What is a Compression Spring?

Definition: compression springs are helically coiled, open-wound springs. These springs have pitch between each coil and, as the name says, are meant to be compressed.

Compression springs are the most common type of spring in the spring industry. They are made of round metal wire. These can be found in different shapes and sizes to fit different applications but the function is the same. Some examples of compression springs are: conical springs, magazine springs, and barrel springs.

 

What is the function of compression springs?

Compression spring functionality consists of the capacity to push back when compressed. This resistance becomes greater the more it is compressed. So, as the spring is being pushed, it becomes harder to do so and it gains more power to try and return to its original shape. However, like all things, this too has a limit. If the load or force placed upon it is greater than the capacity of the spring, it will give in to the pressure, lose its resiliency, and no longer return to its original shape.

How does a compression spring work?

As a spring is compressed, energy is stored. Once that load or force is removed, that stored energy is released thus creating a “spring-back” effect. However, if the spring is compressed past its elastic limit, it undergoes permanent deformation and will not return to its original free length. This is called permanent set. Sometimes, the spring may still work but, because we now have a shorter free length, it will compress to a shorter loaded height.

Due to the high slenderness ratios of some compression springs, they might need to be placed over a shaft or into a tube/hole. This way, it doesn't bend, buckle, or slide to the sides when it is compressed. We can find examples of these cases in different applications such as retractable pens, medical devices, and many other products. When a spring’s slenderness ratio is low, a little pre-load will be enough to keep it in place.
