Helical and Leaf Engineering Springs

One of your basic springs is a helical spring. In essence, a helical spring is a wire wrapped in a coil shape. It is one of the most commonly used engineering springs and can be used and designed to push, pull, or carry different loads. They can be used to store potential energy and then release it as kinetic. Helical springs are also used to absorb shock or maintain a force between two surfaces. They generally take on two forms: compression and tension. A compression spring is designed to push between two surfaces whereas a tension is formed to resist stretching.

Leaf springs are generally used in automobiles for suspension. They are one of the oldest forms of the spring, dating back to medieval times. The leaf is usually a very thin, long, and flat piece of steel that resists being bent and elongates when it's compressed. It can also be used as an anti-roll bar.

Both helical and leaf are excellent for engineering use, but if you want exact precision, continue reading this article for information about conical disc springs, and safety washers.

Advantages of Conical Disc Springs

For specific purposes, there are specific springs. Also known as belleville disc springs, conical disc springs are used for precise accuracy. They can be designed for use in extremely high loads where it would be impossible to use a coiled spring, especially when stacked in a series. When they are stacked, you can achieve much greater deflection and load bearing capabilities, making it more practical versus a coil spring in which you have a set size. For use as engineering springs, bellevilles offer a number of advantages over others including their extremely efficient use of space and their rounded edges to reduce stress. Because of their long life span, they have to be maintained and replaced much less frequently than other springs making them superior over others for most purposes.
