spiral spring
machine component
Quick Summary
A spiral spring is a machine component made from flat strip or wire coiled into a spiral shape, similar to the groove on a phonograph record. This type of spring is used as a compact energy source in devices like clocks, watches, typewriters, and parking meters. It functions by storing energy when deflected and returning to its original shape when the load is removed. Spiral springs can be designed to provide power, arrest moving loads, or offer a controlled force.1
