What is a Torsion Spring?

When it comes to buying springs, you will realize that there are different springs in the market with different uses. In learning about these springs, you know whether they will work for you and serve you the right way. The most sought-after spring in the market is the torsion spring. Here is everything you need to know about it and how it works.

What is a torsion spring?

Before we get started on how it works, you need to know what a torsion spring is. Torsion springs are helical in shape and exert a spiral force. The ends of the spring are extended and attached to other components. Whenever the components rotate at the center of the spring, the spring exerts a force to push them back to their original position. They help store and release angular energy and hold a mechanism in place by defecting the ends.

Torsion springs can work clockwise and anticlockwise, depending on the current application. Even though it is tightly wound, a pitch is added to help reduce friction as the spring works.

Design factors of the torsion spring

One of the things you will notice with the torsion spring is how unique the design is. Most of these design features are what make working with torsion springs easier. With the torsion spring design, designers must look at the maximum deflection, spring rate, and maximum load against the spring wind direction. For the torsion spring to work effectively, the load must be applied against the direction of the wind. It is also vital for engineers to look at the inner and outer diameter of the spring used and the total length of the spring coil.

The mechanics of the torsion springs

The design of torsion springs manufactured by spring manufacturers like GL Metal takes a lot of thought processes based on various mechanics. Here are the main things that engineers look at when making these springs:

  • Inner diameter. It is measured by looking at the width of the coil and perpendicularly to the centerline axis. The measurement is used to see if the outer diameter of a shaft can fit easily into the spring.
  • Outer diameter. The measurement is taken of the outer helix of the coil and is used to see if the space the spring is inserted into allows the spring to move freely.
  • Wire diameter looks that the diameter of the wire coiled to make the spring. It is used to calculate the spring rate.
  • Body light is the measurement of the spring in an unloaded situation. It is found by measuring the outer surfaces of the end coil.
  • Total coil looks at the number of coils in the spring. The value of the total coil needs to be a whole number.

Applications of torsion spring

Now that you know all the design factors and mechanics behind your spring coil, you next need to find out what areas your torsion springs can be used. That way, you are sure you made the right choice in buying the springs. These are the common applications of torsion springs.

  • Used in clothes pegs and clipboard pins. They apply pressure to the clothes and paper as soon as the fingers are released.
  • Spring-loaded hinges. If you need a self-closing door, you will need to get spring-loaded hinges that close as soon as they are open. The torsion springs are added to these hinges to give the self-closing effect.
  • Clock springs also use the torsion spring and are common in wind-up music boxes and the operation of watches and timers.
  • Torsion bar suspensions in cars also use torsion springs to support the trailing arms.

With all these features, it is clear that torsion spring is vital in many industries. You can make informed choices regarding buying the right springs by learning about them. At GL Metal, we have a wide collection of torsion springs in different measurements. Be sure to check them out and figure out which ones will work for you.
