The useful life of a spring is considered to be the duration expectation before it has to go through an adjustment process or breaks during its operation. When a spring reaches one of these two points it is because it is being exposed to a strong load of stress for which the spring is not made to withstand.

Below we will talk more about how to extend the life of a compression spring and what measures must be taken to ensure optimal and long-lasting operation.

One of the first reasons why the spring has a stress load is because of the proportions of its structure. This can be seen mainly in the well-known spring index, which is the correlation between the diameter of the spring and the diameter of the wire, the proportion of these two data is what determines the resistance of the spring, its induced tension and its ability.

In this sense, when a spring has a tight index it will have a low elastic limit and therefore it will remain in a state of stress, which generally happens when the diameter of the wire is larger than the outside diameter.

That a  spring  is in a state of stress is not always bad, especially when the spring has the function of absorbing the shocks of operation, but if the mission of the spring is to travel a certain amount, it is advisable to have a good balance between strength and elasticity, thus extending the life of the spring.

To ensure that your compression spring has a longer useful life it is important to calculate its limits. This can be determined considering various data such as: maximum travel of the spring and its maximum load, in both cases the solid height must be considered.

With this information, you will be able to find out if the pier is designed to support the necessary load and make the required trip without presenting any failure. In those cases where the potential travel is estimated to be higher than the maximum travel, an adjustment can be made by increasing the length of the spring so that it has more force.

Some of the characteristics between a   stressed spring and a light spring are the following:

Spring with stress

• It requires less force, for this it requires less cable diameter, more outer diameter, as well as more coils and more free length.

Light spring

• It requires more force through a larger wire diameter, smaller outer diameter, fewer coils, and shorter length.

If you require a spring that adapts to certain working conditions and that has a long useful life, at Vanel Tech we can help you manufacture the spring tailored to your needs.
