Torsion springs are essential mechanical components that are widely used in various industries and applications, ranging from automotive to aerospace and from machinery to household items. Despite their prevalence, the functionality of torsion springs may remain a mystery to many. In this article, we will delve into the secrets of how torsion springs work, their design considerations, and their applications.
Torsion springs are helical springs that exert torque or rotational force when twisted. They store energy by twisting or winding up, and this stored energy is released when the spring untwists or unwinds. This ability to store and release energy makes torsion springs ideal for applications where rotational force or torque is required, such as in door hinges, clothespins, and electrical switches. They provide the necessary force to open or close doors, secure objects in place, or maintain electrical contacts.
When designing torsion springs, several factors need to be taken into account to ensure their optimal functionality. These include the wire size, coil diameter, coil direction, and the number of active coils. The wire size determines the strength and flexibility of the spring, with thicker wires providing greater strength but less flexibility. The coil diameter affects the spring’s torque and deflection, with larger diameters resulting in higher torque and lower deflection. The coil direction determines whether the spring will unwind or wind up when subjected to a torque, with clockwise and counterclockwise being the two common directions. Finally, the number of active coils influences the spring’s torque output, with more active coils generating higher torque.
Torsion springs are typically made from round wire that is coiled into a helical shape. The wire is first wound around a mandrel or rod, forming the desired coil diameter, and then twisted to create the necessary torque. This twisting process imparts the stored energy into the spring and allows it to exert rotational force when released. After the desired torque is achieved, the ends of the spring are usually formed into hooks or loops to enable attachment and installation.
Torsion springs find their applications in a wide range of industries. In the automotive sector, they are used in suspension systems, throttle mechanisms, and clutch assemblies. In the aerospace industry, torsion springs are employed in landing gear systems, control surfaces, and engine components. They are also commonly found in household items like garage doors, clothespins, and spring-loaded toys. In electrical switches, torsion springs act as contacts to establish or break electrical circuits. Their versatility and ability to generate rotational force make them indispensable in countless mechanisms and devices.
Torsion springs are remarkable mechanical components that play a crucial role in various applications. Their ability to store and release energy through twisting allows them to provide the necessary torque for rotational force. By considering factors like wire size, coil diameter, coil direction, and the number of active coils, torsion springs can be designed to meet specific requirements. With their wide range of applications in different industries, torsion springs continue to be an essential part of our daily lives, even if their functionality remains unknown to many.
According to the informal statistics, the cycle life of high-quality springs can reach more than ten years or even longer under normal use. If the spring quality is not qualified, or there are some improper actions during using process, it may make the springs become premature useless. Then, let's take a look at the factors that cause the premature failure of the spring. Exceeding the specified...

The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force. However, when our goal is achieved, it can return to the starting point specified by us after displacement. Constant force spring has the characteristic of...
In order to make the fridge run efficiently, modern fridge doors can incorporate constant force springs to allow is to close automatically after you have opened the fridge for use. Nowadays it is this design that is still rare on the market, usually magnetic fridge doors. If the door is left open for a long period of time, it can...
