Hey readers, in this article we will read Spring and we will understand the Function, Types, Application, Advantages, and disadvantages of a spring.

Let’s dive into the article.

Spring Definition:

Spring can be defined as an elastic member, whose main function is to deflect under the action of load and recovers it’s original shape when the load is removed. It is a mechanical component.

The function of Spring:

Spring can be used for:

  • To absorb the shocks or Vibration as in-car springs, railway buffers, etc.
  • To measure the forces as in a spring balance.
  • Apply forces in brakes and clutches to stop the vehicles.
  • The function is to store the energy as in clocks, toys, etc.
  • Control the motion as in cams and followers by maintaining contact between two elements.

Different types of Spring:

Spring can be classified into these following types:

  • Helical Spring
  • Conical and volute Spring
  • Torsion Spring
  • Laminated or leaf Spring
  • Disc or Belleville Spring
  • Special Purpose Spring

Helical Spring:

A helical spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces.

Conical and Volute Spring:

Both these spring types have specialized areas of usage where springs with an adaptable rate according to the load is required. In the case of conical springs, they are wound so as to have a uniform pitch while on the other hand volute springs are wound in a slight manner of a paraboloid.

Torsion Springs:

The characteristics of such springs are that they tend to wind up by the load. They can be either helical or spiral in shape. These types of springs are used in circuit breaker mechanisms.

Leaf springs: 

These types of springs are comprised of metal plates of different lengths held together with the help of bolts and clamps. Commonly seen being used as suspensions for vehicles.

Disc Springs:

As the name suggests such types of springs are comprised of conical discs held together by a bolt or tube.

Special Purpose Springs:

These springs are altogether made of different materials such as air and water.

Spring Materials:

Springs are made of the following materials:

  • Hard drawn wire (These are general purpose spring, where we need low-temperature resistance and low stress we can use these types of spring material)
  • Stainless steel
  • Phosphor Bronze (These types of spring are used in Electrical industry due to the material have good electrical conductivity and good resistance to corrosion)
  • Chrome Silicon (This type of spring can be used in high temperature up to 250-degree celsius)
  • Chrome Vanadium (These types of spring have good thermal conductivity up to 220-degree Celsius and also has good fatigue resistance)

Applications of Spring:

Spring can be used in various field such as:

  • Automotives
  • Computer keyboards
  • Mattresses
  • Appliances (toasters)
  • Door handles
  • Compressors
  • Pens
  • Clock
  • Vehicle suspension
  • Watches
  • Mini Drill
  • Lock mechanisms: Key-recognition and for coordinating the movements of various parts of the lock.
  • Pop-open devices: CD players, Tape recorders etc.
  • Spring mattresses
  • Slinky
  • Trampoline
  • Buckling spring keyboards
  • Upholstery: Upholstery coil springs
  • Echo effect in electronic organs
  • Spring can be used for storing of energies
  • Spring can use to measure forces in the weighing machine.

Advantages of Spring:

These are the following advantages of spring:

  • Produce a good cushioning effect
  • Spring has good shock-absorbing ability
  • Latching
  • Locking 
  • Holding
  • Easy to design
  • Cheaper to Produce

Disadvantages of Spring:

Spring has these following disadvantages:

  • Day by day its loose shape and stability


So as of now, we saw the types, applications and some of the other things. These are the basic things related to spring. I hope you understand it, feel free to pitch your doubts in the comment section, and also do share your thoughts regarding my article.

And here is the short recap:

What are the different types of spring?

Spring can be classified into these following types:
1. Helical Spring
2. Conical and volute Spring
3. Torsion Spring
4. Laminated or leaf Spring
5. Disc or Belleville Spring
6. Special Purpose Spring

Why we use spring?

We use spring for:
1. To absorb the shocks or Vibration as in-car springs, railway buffers, etc.
2. To measure the forces as in a spring balance.
3. Apply forces in brakes and clutches to stop the vehicles.
