Get compression, coil and conical springs at one place
A compression spring is a type of open-coil spring that store energy when a force shortens them. These springs are designed to operate with a compression load, so the spring gets shorter as the load is applied to it. The energy so stored in the spring is relinquished after the force is removed to extend the spring and push against the object that compressed it. Compression springs are generally in extended mode and they have the most of the potential energy when they are compressed and that will mean that they release the potential energy when uncompressed. these open-coil springs are widely used in automotive suspension, clock springs and spring mattresses. A compression spring has units of force divided by distance, for example lbf/in or N/m.
Configuration of Compression Springs
Although most commercially available compression springs possesses the same diameter throughout the spring there exist some rare types that are shaped like an hourglass, a cone or a barrel. Conical springs are usually only used when a low solid height and a higher resistance to surging is required in any specific operation.
Dimensions and Rate of Compression Springs
Some important features of a spring are its outer diameter, inner diameter, wire diameter, free length and solid height. Free length of a spring is the length of the spring when it is unloaded, while the term solid height refers to the length of the spring when it is loaded enough to bring all of the coils into contact. The spring rate is the amount of load required to compress the spring through an unit inch.
Ends of an Compression Spring
Normally compression springs appear to have have squared or ground ends, meaning the ends are either cut straight off at the end or are cut at an angle that tapers to a flat point. This probably because, square ends facilitate a better transfer of force in the spring, while ground ends provide more stability. The ends can be either open or closed, meaning the last coil is either equidistant from all the other coils or the last coil is pressed up against the previous coil. Closed ends offer more squareness. It is always advisable to have the both ends of the compression have parallel plates so that force can be applied evenly.
Applications of compression Springs
Probably the most common example of compression spring is the pogo stick, that children use to play with. In addition, these open-coil springs are widely employed in the automobile and aerospace industry and in manufacturing mattresses and earthquake resistant foundations.
