A convolution spring is a spring with a flat, convoluted shape that has the property of storing and releasing energy. It is fixed at one end and can be torqued at the other. When coiled by an external force, a convolution spring stores elastic potential energy, and when the external force disappears, the spring gradually releases the elastic potential energy and returns to its original shape. Its Elastiska egenskaper är relaterade till antalet spolar, tjocklek, bredd och andra dimensioner på fjädern . Till exempel, med samma material och bredd, ökar antalet spolar att öka vårens förmåga att lagra energi, samtidigt som fjäderns tjocklek ökar dess torsionsstyvhet .}}}}}}}}}}}}}}}}}}}}
In mechanical clocks and watches, the convolution spring is the central component. It stores energy as the spring is wound by the winding operation, and then slowly releases that energy to drive the clock's gear train, which in turn moves the hands. In automotive seat adjusters, the convolution spring can be used as an auxiliary power source.
