Spiral Wound Torsion Spring: A Guide to Design, Function, and Applications

A spiral wound torsion spring is a type of mechanical spring that is designed to work in torsion or twisting applications. This spring is made up of a flat strip of metal that is wound in a spiral pattern around a mandrel or core. The spring is then heat-treated to ensure that it maintains its shape and properties.

Design

The design of a spiral wound torsion spring depends on the application and the specific requirements of the spring. The most important design factors include the material used, the dimensions of the spring, the number of coils, and the direction of the wind. The material used for the spring must have the necessary strength and flexibility to withstand the stress of torsion. The dimensions of the spring are determined by the space available for the spring and the amount of torque that must be applied. The number of coils in the spring affects its stiffness and the amount of torque it can generate. The direction of the wind of the spring can be either left-hand or right-hand, which determines the direction of the torque.

Function

Spiral wound torsion springs function by twisting or rotating around their axis when a torque is applied to them. The spring resists the twisting force and stores energy in the form of torque, which can be released when the torque is released or when the spring is allowed to unwind. The amount of torque that can be generated by the spring depends on its stiffness, the number of coils, and the material used.

アプリケーション

Spiral wound torsion springs are used in a variety of applications where torque or rotational force is required. They are commonly used in automotive applications like door locks and opening mechanisms, as well as in industrial machinery and equipment such as valves, clutches, and brakes. They are also used in medical devices, toys, and electronics.

Conclusion

Spiral wound torsion springs are a versatile and effective type of spring that can be used in a wide range of applications. Their design and function make them ideal for torque or rotational force applications, and their strength and durability make them a reliable choice for demanding environments. By understanding the design, function, and applications of spiral wound torsion springs, engineers and designers can choose the right spring for their specific needs and requirements.
