Speaking of coil springs , I don’t know if everyone is 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 deepen our understanding of coil springs. Now let's take a look. Coil springs are mechanical storage structures primarily used in other ancient ranged weapons. The coil spring is released by twisting or rotating the soft and high-toughness elastic material, and uses the lever principle to give the projectile a certain amount of mechanical energy.
The design principle of coil springs utilizes the lever principle, using soft and tough materials to twist or rotate elastic materials, which has huge mechanical energy. The working part of the spring subjected to torsional deformation is also surrounded, tightly enclosed or separated by each wheel. The end structure of the torsion spring is processed into torsion arms of various shapes, from single torsion to double torsion, and can even form various torsion bar deformations 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 flow of the coil spring affects the free length of the hooks at both ends and the tension spring. Determine the size and outer diameter of the confined space. The pretension load can also determine the material of the spring and the diameter of the steel wire, and the tightness 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, consider the wearable space. Determine the outer diameter, free length and number of revolutions of the space spring.
There must be a point in the coil spring that determines the length and shape of the torsion bar. The angular position relative to the fulcrum represents the length, shape, and angle of the fulcrum of the lever exerting force when no force is applied. The coil spring design structure is the core of the deformation spring, and it needs to be shaped according to the design. A central axis or control handle for support. The dimensions of the central axis allow for approximately 10% spacing between the listed deviations.
The greater the deviation, the smaller the size of the control handle. In order for the coil spring to function well, there must be enough space in the component. Small axis spacing cannot refer to 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.
