Extension Spring Failure

Posted on December 5, 2017

Most Common Reason Extension Springs Break or Fail

Extension Spring FailureExtension spring failure can cause serious problems in spring applications. When extension spring failure occurs, it is most often because the spring is overstressed, due to a flawed design. When the amount of force or stress applied exceeds what the spring design allows for, the spring may break or take set. For instance, an extension spring designed for strength will have very little elasticity. When stretched too far, it becomes overly stressed and susceptible to breakage. The failure is most likely to occur at the spring body or at the spring ends.

Extension spring ends are characteristically more fragile at the ends than within the body. During the formation of the loops or hooks, the wire is bent upward and the diameter of the ends is reduced slightly. The bend and smaller diameter creates a significant concentration of stress. When an extension spring is properly designed, this concentration is accounted for, to avoid premature failure.

Other reasons for failure, apart from a flawed spring design, are unforeseen environmental implications and improper installation.

Extension spring failure can be avoided by providing your spring supplier with accurate information about how the spring will be used. This includes details such as the required extended length and load as well as the actual measurements of an existing spring. Providing precise the details reduces the likelihood of spring overstressing. For instructions on how to properly measure an extension spring as well as a list of what information your spring supplier needs, visit our extension springs page.

The best way to assure that your springs are properly designed for your application is to work with an experienced custom spring supplier. WB Jones has been manufacturing quality extension springs for over a century. Contact us to discuss your needs!

Understanding Options in Spring Materials

Posted on September 28, 2017

There are a wide range of spring designs to accommodate an extensive array of applications, including extension springs, compression springs, torsion springs, and custom spring designs. Spring end types and shapes vary significantly depending upon the type of job they are designed to do. A not so obvious difference in springs is the type of material used in its fabrication. Different spring materials are available to suit the wide variety of jobs they do. Knowing the characteristics of the spring materials you can choose from will help you to choose the right spring for your application.

Even with the broad spectrum of spring applications, the vast variety of springs are fabricated from six basic types of materials. The chart below shows the different materials and their respective characteristics.

Material Characteristics
Music Wire Highest quality cold drawn, high carbon wire. High strength with a good surface finish.
Hard Drawn MB Cold drawn wire for average stress applications. Medium strength and low cost.
Oil Tempered Wire Wire is cold drawn and heat treated before fabrication. Good general purpose spring wire for torsion springs and springs that require a large wire diameter.
Stainless Steel 303 Cold drawn general purpose wire. Features include corrosion and heat resistance.
Phosphor Bronze Not used as commonly due to cost. Cold drawn, featuring good corrosion resistance and electrical conductivity.
Brass Not used as commonly due to cost. Tends to tarnish and change color over time. Features good corrosion and water resistance.

Torsion Spring Design

Posted on August 29, 2017

torsion spring designTorsion springs are helically engineered springs that operate by exerting torque. They work by applying rotary force to two objects, or parts of a finished product. A simple example of a torsion spring application would be a clothes pin. The torsion spring statically holds the pin closed by deflecting the spring legs across the centerline body axis. The torsion springs can also store and release angular energy.

Torsion springs are engineered to varying specifications of load, wind, deflection, spring rate, and other properties. A number of considerations go into torsion spring design. Design details are dictated by the application and are based on factors such as:

  • Dimensional constraints
  • Rod usage
  • Body length
  • Leg bend and length
  • Deflection length
  • Required torque
  • Free length angle
  • Material

Torsion spring design considerations also include whether or not a finish will be used, and if so, what type of finish will provide optimal performance for the application. When torsion springs are needed for corrosive environments, in which the spring will be exposed to harsh weather or moisture, stainless steel or another type of corrosion resistant metal will be used. If the conditions are especially demanding, however, an additional finish may be needed to provide optimal performance. A few finish options that are commonly used include black oxide, passivate, gold iridite, and zinc.

When the spring is not well-suited or designed for the application, torsion spring failure can occur. Corrosion or other steadily destructive forces can lead to serious problems. Since torsion springs are most often used in applications that involve large amounts of force, sudden and unexpected failure can put nearby property, or worse yet, people at risk. It is critical that torsion spring design be appropriate for the job. The best way to assure you get the right torsion spring design that will deliver performance, reliability, and safety is to choose a knowledgeable and experienced manufacturer.

W.B. Jones has over 100 years’ experience providing quality torsion springs, both stock and custom to meet your needs.

Spring Life Expectancy

Posted on July 31, 2017

Spring Life ExpectancySprings play an important role in the function of many products and systems. When choosing springs, spring life expectancy is an important consideration. Since springs are used in such a broad range of applications and environments, spring life expectancy can vary and can be difficult to determine.

Some of the variables that influence spring life expectancy include materials used, environmental conditions, and the amount of force involved in the application. The way a spring is designed also affects how long the spring will last. In fact, most cases of premature spring failure occur due to a flaw in the design of the spring.

Spring design flaws that influence life expectancy can involve poor materials and workmanship, but they can also be due to improper design. If a spring was not designed properly for its application, you can expect the spring life to be very short. Stress or force beyond what the design allows can lead to spring breakage or cause the spring to set. For example, an extension spring designed for strength may lack flexibility. If extended too far, it may break in the body or at the ends.

Choosing the right material for the application is also important part of the design. Hard drawn wire is most commonly used for low stress applications, while high stress applications need a stronger choice, such as music wire. If the spring will be exposed to harsh elements, consider using a grade of stainless steel or zinc plating. These options will deter rust and improve the spring’s life expectancy.

One of the most important things to keep in mind about life expectancy is that it is very difficult to determine.  There are so many different factors involved, some of which are unknown, that it’s hard to define. The environment in which the spring operates is probably the biggest unknown. Discussing these environmental factors with our team will help ensure proper design and in turn a longer lasting spring.

In order to achieve optimal spring life expectancy, trust a spring supplier that will assist you in evaluating your process and determining the best design for your job. The spring design specialists at WB Jones are here to assist! Contact us today!
