Spiraalijousia

Spiraalijousia, commonly known as coil springs, are mechanical devices made from a helical spring forged from an alloy. Their primary function is to store and release mechanical energy, absorb shock, and maintain a force between contacting surfaces.

There are several main types of spiraalijousia. Helical springs are the most common, further divided into compression springs, which shorten under load; extension springs, which lengthen under load; and torsion springs, which resist twisting. Other forms include conical springs, which can offer a variable spring rate, and flat springs, which are often used in clockwork mechanisms and electrical contacts.

The material used for spiraalijousia is crucial to their performance. Common materials include steel alloys like carbon steel and stainless steel, chosen for their elasticity and strength. The design of a spiraalijousi, including the wire diameter, coil diameter, number of coils, and pitch, determines its spring rate (the force required to compress or extend the spring by a certain distance) and its overall behavior.

Spiraalijousia find widespread application across numerous industries. They are essential components in vehicle suspensions, providing ride comfort and handling. In furniture, they offer support and resilience. They are also used in pens, trampolines, mattresses, and various industrial machinery. The ability of spiraalijousia to exert a restoring force makes them indispensable for countless mechanical functions.
