Compression springs are parts that use the reaction force of spring for objectives such as receiving mechanical movements or absorbing shocks or loads. They are used in many tools and products such as machine tools. Hooke’s Law states that the more you deform a spring, the more force it will take to deform it further. Using the example of a common compression spring, the more you compress the spring, the more force it will take to compress it further. Understanding how and when a wave spring can fail is important for achieving optimal performance in your application. One common reason a wave spring could fail is because of overstressing, otherwise known as over-compression of the spring.
Although a tension and compression spring are both helical coiled springs, the difference in their functionality and purpose can be significant. In essence, tension springs are designed to bring components together, whilst compression springs are made to keep components apart. They are commonly referred to as coil springs and in some instances also known as helical coil springs. Some of the most popular names are: Basic compression spring, Coil spring, Helical coil spring, compress springs, push springs, etc.
A compression spring’s dimensions are measured by Outer Diameter (OD), Inner Diameter (ID), Free Length, Wire Diameter, and Total Coil. Dial calipers are best to get an exact measurement. For outer diameter readings, the calipers are placed on the outside of the coil’s width. Compression springs are open-coil helical springs that resist compressive forces as they are applied to them. When a heavy object or force is applied to the spring, it condenses, storing the force until it is eventually released.
