Speaking of double torsion springs , I don’t know if you are familiar with them. Everyone must have heard of spring, which is a spring-like mechanical structure that plays an important role in the mechanical field. We need to pay special attention to the design of double torsion springs, including the design principles, design process, design structure, and design standards of double torsion springs. Knowing this, we will have a deeper understanding of double torsion springs. Let’s take a look below.
Introduction to double torsion spring
The double torsion spring is a mechanical energy storage structure. The torsion spring accumulates force by twisting or rotating the soft, high-toughness elastic material, and releases it using the lever principle, so that the launched object has a certain mechanical energy.
Double torsion spring design principles
The double torsion spring uses the lever principle to twist or rotate the soft, high-toughness elastic material, giving it great mechanical energy. It is a spring subjected to torsional deformation, with its working parts tightly or individually enclosed. The end structure of the torsion spring is processed into torsion bars of various shapes, from single to double torsion, and even the deformation of various torsion bars, must be formed according to the design. Torsion spring is a commonly used balancing mechanism in machinery and is widely used in industrial production such as automobiles, machine tools, and electrical appliances.
Double torsion spring design principle
The two ends of the tension spring will affect the shape of the hook and the free length of the tension spring. This space can determine the size and outer diameter of the bonded portion. In addition, the pretension load determines the material and wire diameter of the spring, and the size of the bonded part can adjust the pretension length. The setting of the inner diameter of the double torsion spring depends on the size of the mandrel, but the change of the spring body after torsion should be considered, so an appropriate margin should be left. If the torsion spring device is built-in, the built-in space should be considered. Space determines the outer diameter, free length and number of turns of the spring body. There must be a point when the double torsion spring does work, and this point can determine the length and form of the torsion bar. The angular position of the force applied torsion bar relative to the fulcrum when not in operation can clearly define the length, form and angle of the fulcrum bar.
Double torsion spring design structure
Torsion springs are the pinnacle of deformed springs, ranging from single and double torsion springs to double and double torsion springs, special double torsion springs, and even the deformation of various torsion bars can be shaped according to the design. Used to support spindles or mandrels. The spindle is sized to allow approximately 10% of the listed deviations. If the deviation is large, the spindle size should be reduced. In order for the double torsion spring to function in good condition, there must be enough space in the assembly. The minimum axial space cannot refer to the length of the coil. Double torsion springs should be used in the winding direction. The maximum load is lower in the loosening direction due to residual stresses.
