Torsion Helical Spring

A torsion helical spring, also known as a torsion spring or a helical torsion spring, is a type of mechanical spring that is designed to exert torque or rotational force when twisted. It is typically made from a round wire that is formed into a helix shape, with the ends of the wire attached to some form of support or load.

Torsion helical springs are commonly used in various applications where rotational force or torque is required. They can be found in a wide range of products and systems, including automotive suspensions, door hinges, electrical switches, and even in mechanical watches.

The design of a torsion helical spring allows it to store and release energy when twisted. When a torsion force is applied to the spring, it resists the twisting motion and exerts an equal and opposite torque. This torque can be used to provide tension, compression, or a combination of both, depending on the specific design and application.

The characteristics of a torsion helical spring, such as its torque capacity, deflection angle, and stiffness, can be customized by adjusting parameters such as the wire diameter, coil diameter, number of coils, and the material used. Common materials for torsion springs include steel, stainless steel, and various alloys.

Overall, torsion helical springs are versatile mechanical components that play a crucial role in many different systems and applications, providing reliable and efficient torque or rotational force.
