Although springs have a deceptively simple appearance, they are an essential design component for various engineering applications. An extension spring is a way to go if you need to store energy or create a barrier to a force acting in one direction. Engineers in the medical, electrical, manufacturing, and farming industries will find this especially helpful for various reasons.

If you want to design a component that can reliably provide the desired outcome under specific conditions, evaluating the principal function of a tension spring is beneficial.

What are extension springs?

 

As their name implies, extension springs (tension springs) are springs that can be altered by stretching to expand their length. These springs get into tension as their length is increased. The ends of most extension springs feature a hook or an eye for easy attachment, and the spring exerts a pulling force when the parts are separated.

In contrast to compression springs, which need to be supported along their length, extension springs remain under tension the entire time. Most extension springs on the market are coiled springs made from steel wire.

How do extension springs work?

 

Coil springs used in extensions are firmly twisted, leaving no space between the coils. When you apply tension to an extension spring, the coils unwind, allowing the spring to stretch. A coil's ability to resist this force allows it to store mechanical energy. When the tension is removed, the spring returns to its original form with no space.

How are extension springs used in engineering?

 

Controlling Movement

 

One of the most obvious applications of springs is regulating lateral motion, like opening and closing a door. Tension springs are versatile enough to be employed either to initiate an opening or closing motion or to reduce the impact of such a motion when an external force induces it, which means the spring can be tailored to meet the system's overall requirement for force over a given distance with relative ease. 

Since the extension spring stores energy instead of deflecting it, the forces at play are always important to consider. This concept is also responsible for the spring's bouncing action. While this has its uses, maintaining tight control over the system's moving elements necessitates a means of counteracting it.

Circuit breakers and switches

 

Engineers can take advantage of the many properties of extension springs beyond their use in common applications. You can implement tension spring technology in circuit breakers and switches. Since springs can store energy, you can use them as vibration dampers.

Accordingly, just like locking pliers, you can employ extension springs to secure a mechanical component, which is functionally comparable to a diaphragm valve, which uses a network of tension springs to regulate an opening in proportion to the magnitude of the force applied to it, operates.

Using an extension spring for this purpose has the distinct advantage of not needing any external power, which can be scarce in times of crisis.

Farm Machinery

 

Heavy-duty extension springs are used in farm machinery because of the tremendous pulling force required. You can use extension springs on your farm to their full ability, whether tractors or combine harvesters. Moving big objects around your farm and plowing fields are all examples of hard labor on your farm that extension springs can help you with.

Although hook and loop extension springs are the most common in heavy machinery, other types exist. When problems arise with your farm equipment, like rusty springs, it's time to get a new set as soon as possible; therefore, you must visit a reliable company to find replacements.

Taking Accurate Measurements

 

The extension spring is also frequently employed by engineers in the measurement of system-wide force magnitudes. Using a tension spring, you can primarily do one of two things to measure these dynamic forces: To that end, the springs can be designed to generate a target quantity of pulling force according to a specified extension rate. You can then figure out how much force is being applied to the spring by how far it is stretched.

Take Away

 

Extension springs last for quite some time. Although they come in various materials, the most common ones are composed of hard metals like stainless steel. There is no need to worry about them breaking down on you at an inconvenient moment, as tension springs have a very long lifespan, even when subjected to a constant tension strain. It would help if you seek advice from a professional spring manufacturer before you decide which extension spring best fits your application.
