A helical spring, often referred to simply as a coil spring, is a mechanical spring that is made up of a wire wound in the shape of a helix or coil. These springs are commonly used in a wide range of applications to store and release mechanical energy. When a force is applied to compress or extend the spring, it deforms, storing potential energy. When the force is released, the spring returns to its original shape, releasing the stored energy.
Helical springs are used in various industries and applications, including automotive suspension systems, industrial machinery, toys, and more. They come in different shapes and sizes, and their characteristics, such as stiffness (spring rate) and load-carrying capacity, can be customized to suit specific requirements.
The design and specifications of a helical spring can vary significantly depending on its intended use, with factors like wire diameter, coil diameter, number of coils, and the material of the wire all influencing its performance.
