Types of Springs And Their Application

What are springs?

A spring is an element made of various materials, such as plastic, carbon steel, stainless steel or copper, which has elastic properties and has a great diversity of shapes and models depending on the function it must fulfill.

Its main characteristic is that of being able to undergo permanent deformation when various forces come into action, since it stores force and then detaches itself from it at high speed. Once this process is finished, it returns to its initial state, without receiving any apparent damage.

It is subjected to large tensile or torsional forces as appropriate. They are generally designed to offer resistance or damping a certain element in particular. They can be found from everyday objects, such as telephone cables or television controls, to vehicle parts such as shock absorbers.

This is because it uses a certain force that then transforms it into energy depending on what the situation in question demands. To determine what type of spring is necessary for machinery, formulas and accounts are used at a physical-mathematical level .

To determine what type of spring should be used in a given situation, several factors must be taken into account, such as: number of coils, winding direction, distance between coils, coil diameters, length in free state, spring load.

Springs: some classifications

They can be classified in different ways:

According to the shape of the spring:

  • Helical cylindrical: For its elaboration a large number of materials are available, the most used is steel. The coils are usually thicker than the others and are manufactured hot
  • Helical conical: These types of springs are characterized by having great rigidity, which increases  as the load increases. When it disappears, it returns to its starting point. Its use is not very frequent.
  • Coiled: These are usually torsion springs that do not require a lot of axial space. Thanks to their large amounts of spirals arranged closely together, they are used mainly in the area of watchmaking, rolling meters, mechanical toys, etc. They are made of a stainless steel sheet.
  • Laminar: It is made up of several sheets of steel or other material arranged one above the other in a curved or straight way. They are usually used in vehicles to cushion the blows produced by the imperfections that a road can have. They are located between the chassis and the wheel axle.

According to the shape of the cross section of the thread:

  • Circular
  • square
  • Rectangular

According to the type of load they support:

  • Compression: As the name implies, they are built only to withstand any pressure . There are conical, bionic, cylindrical, etc.
  • Torsion: Its function is to twist or rotate. This is because it contains very elastic properties, since it can store mechanical energy when it rotates and return it when the process ends. The force it releases is directly proportional to the number of turns that is produced.
  • Traction: They are characterized by using only traction force . At their ends they have two hooks that adjust and hold on to the element in question. Different models can be found: German, English, Catalan, rotating, open, closed, etc. The hooks on their tips allow these springs to be mounted anywhere and in any way.
  • Bending: bending spring is called a compression spring formed by another type of more elastic washers or spirals with another one mounted but that fulfill the same function. They are characterized by having a distinctive feature: if one of the washers that composes it breaks, it does not affect the operation of the spring itself , that is, it can continue marching in the same way as before the altercation.

What are the 4 types of springs?

Different types of springs: compression, extension, torsion, & constant force springs.

Where are springs used in real life?

They’re often used in everyday electronic toys, and in the batteries we use to make them come to life. Springs have been important to the toy making industry long before electronic toys. From the Jack-in-the-box to wind-up toys, many toys using springs have become iconic classics and are still popular today.

What is spring function?

A spring is an elastic object that stores mechanical energy and releases it when the opposing force is removed. If you need to apply force to create movement or hold something in place without the use of engines or other powered means, springs could be the answer.

What are springs in groundwater?

A spring is a location at the land surface where groundwater discharges from the aquifer, creating a visible flow. This discharge is caused by difference in the elevation of the hydraulic head in the aquifer and the elevation of the land surface where the discharge takes place.
