Speaking of coil springs , I wonder if we are familiar with them. This is a spring-like mechanical structure that plays an important role in the mechanical field. Special attention should be paid to coil spring design, including coil spring design principles, design processes, design structures, design standards, etc. Understanding this will further your understanding of coil springs. Now let's take a closer look. Introduction Coil springs were mechanical storage structures primarily used in other ancient ranged weapons. The coil spring is released by twisting or rotating the soft and tough elastic material using the lever principle, giving the projectile a certain amount of mechanical energy.
The design principle of coil springs utilizes the lever principle to produce great mechanical energy through the twisting or rotation of elastic materials that are soft and tough. The spring that undergoes torsional deformation, the working part is also surrounded, tightly enclosed, or separated by each wheel. The end structure of the torsion spring is a torsion arm processed into various shapes, from single torsion to double torsion, and even the deformation of various torsion rods can be formed according to the design. Coil springs are generally used in the balancing mechanism of machines and are widely used in industrial production such as automobiles, machinery, and electric power.
The design of a coil spring affects the hook shape and free length of the tension spring at both ends of the tension spring. The space determines the size and outer diameter of the tight parts. The pretension load can also determine the spring material and wire diameter, and the tightness size can adjust the pretension length. The inner diameter of the coil spring depends on the size of the central axis, but the change of the spring body after torsion must be considered, so an appropriate margin must be ensured. If the coil spring device is wearable, wearable space should be considered. Space determines the outer diameter, free length and number of revolutions of the spring.
The coil spring must have a point that determines the length and shape of the torsion bar. The angular position relative to the fulcrum when no force is applied specifies the length, form, and angle to the fulcrum of the lever exerting the force. The coil spring design structure is the ultimate deformation spring, and it needs to be shaped according to the design. A central axis or control stem for support. The bottom bracket is sized to allow approximately 10% of the listed deviations.
The greater the deviation, the smaller the size of the control stem. In order for the coil spring to function well, there must be enough space in the component. The small axis space cannot be referenced to the coil length. Coil springs should be used along the winding coil. The maximum load is lower in the direction of loosening due to residual stress.
