Extension Helical Spring

An extension helical spring, also known as a tension spring or a coil spring, is a type of mechanical spring that is designed to resist stretching or extension. It is made up of a tightly wound coil of wire, with the ends of the coil typically formed into loops or hooks to allow for attachment to other components.

Extension helical springs work by storing potential energy when they are stretched or extended. When a force is applied to the spring, it stretches and stores energy. Once the force is removed, the spring returns to its original shape and releases the stored energy, exerting a force in the opposite direction.

These springs are commonly used in various applications, such as automotive suspensions, industrial machinery, household appliances, and even in everyday items like pens and toys. They are designed to provide tension or pulling force, and their strength and characteristics can be customized based on the specific requirements of the application.

When selecting an extension helical spring, factors such as the material, wire diameter, coil diameter, and number of coils need to be considered to ensure that the spring can withstand the desired load and provide the required extension force.

Overall, extension helical springs are versatile and widely used components that provide tension and extension capabilities in various mechanical systems.
