Design principle of double torsion spring

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 double torsion spring is processed into torsion bars of various shapes, from single torsion to double torsion, and even various torsion bars, which must be shaped 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 process
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 torsion spring depends on the size of the spindle, but the change of the torsion spring body after torsion must be considered, so an appropriate margin must be left. If the torsion spring device is embedded, the embedding space should be considered. Space determines the outer diameter, free length and number of turns of the spring body. The torsion spring must have a support point when working, which can determine the length and shape of the torsion bar. The angular position of the torsion bar relative to the fulcrum when not in operation clearly defines the length, shape and angle of the pivot bar.
Double torsion spring design structure
Double torsion springs are the pinnacle of deformed springs, ranging from single torsion springs to special torsion springs for double torsion springs, and even various torsion bars can be shaped according to 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 torsion springs to function well, the space in the assembly must be sufficient. The minimum axial space cannot refer to the length of the coil. Double torsion springs should be used in the direction of winding the coil. The maximum load is lower in the loosening direction due to residual stresses.
