Compression Springs

Compression springs come in several options suitable for a variety of applications and can be used as pure energy accumulators, shock absorbers, vibration dampers or force generators.

Springs are among the most useful and important mechanical components. Moreover, springs are considered an important part of most assemblies and mechanisms.

Selecting the right spring materials and dimensions is crucial for the success of your project and can help you get the longest service life possible. Our spring design guide explains all this in great detail or just call 780-442-4020 for immediate access to one of our in house engineers. They will be happy to share their expertise and answer any questions you may have.

Our experienced team of in-house engineers at Victory Spring can help you find the exact compression springs for your needs and ensure you’re not overloading or overstressing them, which can lead to damage and added expenses that could have been avoided. We can also design custom solutions and inventory programs to keep you stocked.

Compression springs are of a specific design and we will take a deep look at each type. Victory Spring have one of the largest compression spring inventories in the area.  Before we go into further details, let’s define what a compression spring is and how it works.

Compression Springs – Engineering Marvels of the Modern World:

A compression spring is an open-coil helical spring that provides resistance to a compressive axial force axially. The majority of compression springs are a constant diameter and have a relatively linear spring rate.

There are some different forms of compression spring, which may include concave (barrel), convex (hourglass), or conical. These types of springs do not have a linear spring rate and need special care to ensure a successful design. .

Service Life:

Victory Spring is among the best spring manufacturers in Canada that is devoted to offering top-quality springs with long service life.

We are often asked to provide an estimate of the life span of a spring or its typical cycle life. In most cases, there are many variable factors which make an accurate prediction very difficult but as a rule, we try to ensure that the working range of the spring is within 15% to 85% of the total available deflection.

We can also look at options such as pre-setting or shot-peening which has been proven to extend cycle life by 500% in some cases.

Materials:

At Victory Spring, we are proud to offer the best quality products to our customers.

As a leading spring manufacturer, we utilize only the highest quality spring wire while fabricating our springs. Every batch of wire is identified by its heat number and is traceable back to the mill source.

Specs of a Compression Spring:

A compression spring has 4 main characteristics.

• Wire dia.
• Coil Diameter which can be measured as OD or ID
• Free Length
• Number of Coils

The spring rate is determined by the combination of wire size, coil diameter and the number of coils. So when we are creating a new design and the number of coils is unknown, we can back-solve to determine that value.

If you have a sample spring and need us to make a replacement, we will always ask you to confirm the 4 points above. Alternatively you can always send us your sample and we can do all the measuring here.

Compression Springs – Designing from scratch:

If you are designing a new spring loaded mechanism or if you are needing to make changes to your existing spring design, here are some further questions that our engineers will explore with you.

• How much space do you have?  Compression springs often have a constraint on the OD or ID, such as a bore or a shaft that the spring fits over or into. The dimensions of those constraints are important to know so that we can ensure the new design will operate without friction.
• How much travel or working stroke do you need? A compression spring will normally have 2 load points, an installed or “preload” point and then a “working” point. The difference between your preload point and your working point is called your working stroke or  working deflection. it is important to ensure that the spring has sufficient working stroke so that it will not bottom out.
• Where is the spring being used?  Factors such as operating temperature and the possibility of corrosion must be considered in order to select the correct material alloy.

It may seem like a lot of questions for something that you thought was just a simple spring, but we are passionate about creating the best solution for your application and to us there is no such thing as just a simple spring.

Helix

The helix can also be specified as right handed or left handed.
