Micro Torsion Springs

Torsion springs are mechanical springs designed to provide torque or rotational force when they are twisted or rotated around their axis. They are widely used in various applications to store and release energy by undergoing torsional deformation. Here are some key characteristics and applications of torsion springs:

Micro torsion springs have many diverse applications, including industrial machinery, automotive components, medical devices, electronics and consumer products. Micro torsion springs can be customized to suit the specific needs of each application as needed.

To maximize performance and life span of a micro torsion spring, consider the following spring design considerations and characteristics. Torsion springs are typically made from a single wire wound into a helical or spiral shape. The wire is wound tightly to create coils that can store and release energy when the spring is twisted. Micro torsion springs have two ends or legs, and they work by exerting a torque or rotational force when one end is twisted relative to the other.

Torsion springs operate by undergoing angular deflection, meaning they twist or rotate along their axis. The amount of deflection is determined by the design parameters of the spring. The primary function of a micro torsion spring is to generate torque, which can be used for various purposes, such as closing doors, controlling valves, or providing resistance in a mechanism. Micro torsion springs are typically made from materials such as music wire, stainless steel, or various alloys, chosen based on factors like the application's environment and load requirements.

Key Micro Torsion Spring Design Parameters
Designing micro torsion springs involves considering several key parameters to ensure their proper function and reliability within a specific application. Micro torsion springs are designed to provide torque when twisted or rotated around their axis. Here are the essential design parameters for micro torsion springs:

Wire Diameter: The wire diameter is the thickness of the spring wire. It is a crucial parameter as it determines the spring's strength, flexibility, and load-carrying capacity. Selecting the appropriate wire diameter is essential to meet the desired spring force and deflection characteristics.

Outer Diameter: The outer diameter is the overall diameter of the spring coil. It is determined by the wire diameter, the number of coils, and the pitch (distance between each coil). The outer diameter affects the spring's size and fit within the application.

Inner Diameter: The inner diameter is the diameter of the space inside the coil. It can vary depending on the application's requirements. The inner diameter affects the initial tension and how the spring fits over a shaft or rod.

Free Length: The free length is the length of the spring when it is not under any load or tension. It represents the spring's relaxed or uncompressed state. The free length influences the range of motion or deflection available for the spring.

Total Coils: The total number of coils in the spring affects the spring rate and the amount of deflection it can provide. Increasing the number of coils generally results in a softer, more flexible spring.

Pitch: The pitch is the distance between successive coils of the spring. It is determined by dividing the free length by the total number of coils (P = L0 / N). The pitch affects the spring's flexibility and spring rate.

Initial Tension: Initial tension is the force or preload applied to the extension spring when it is in its free, unloaded state. It is often specified to ensure that the spring remains tight or taut when attached to the application. Initial tension is related to the spring's wire diameter and the number of coils.

Load or Force Requirements: The load or force requirements refer to the amount of force the spring needs to exert or withstand in the application. It is crucial to specify the required force accurately to select the appropriate spring rate and dimensions.

Spring Rate: The spring rate, also known as the stiffness or rate constant, represents the amount of force the spring exerts per unit of deflection (typically in pounds per inch or Newtons per millimeter). It is calculated as the change in force divided by the change in length (k = ΔF / ΔL). The spring rate affects how the spring responds to changes in load.

Maximum Deflection: The maximum deflection is the distance the spring can stretch from its free length under the application's maximum load. It is crucial to ensure that the spring's design allows for adequate deflection without exceeding its elastic limit.

Material Selection: The choice of spring material is critical and depends on factors such as the application's environment, temperature range, and corrosion resistance requirements. Common materials include music wire, stainless steel, and various alloys.

End Configurations: The design of the spring's ends, including hooks, loops, or other configurations, should be chosen based on how the spring will be attached to the components it will act upon.

Properly considering and balancing these design parameters is essential for the effective design of micro torsion springs, ensuring they meet the specific requirements of the application while maintaining their durability and performance.
