    When the tension spring is formed, the spring coils generate a compressive force with each other. When the tensile force acts on the spring, if the force is less than the compression force of the spring, the spring will not deform. If the force is greater than the compression force of the spring, the spring begins to deform. The tensile load corresponding to this compressive force is the initial tensile force. The initial tensile force of the tension spring depends on the type of material, the diameter of the material, the winding ratio of the spring, and the processing method.The end shape of the tension spring is mainly a hook ring. These hook rings are bent by the end spring ring or material. When designing or selecting the end structure, the installation method, installation space and load property of the spring in the mechanism are mainly considered. And other factors, as long as all conditions are met, try to choose a simple mechanism shape.Semi-circular shackle: bent by half spring at the end of the spring for space limited applicationsTorsion round shackle: It is formed by bending the spring end to the center, forming a high stress outside the bending and twisting, which is suitable for a large winding ratio and a small load environment.Eccentric round shackle: It is bent by the end coil. The shackle is located at the tangent position of the edge of the spring ring. Due to the eccentricity of the load and the 90 degree bending of the root of the shackle, the spring is subjected to a large load stress.Rotatable shackle: The relative position of the shackles at the ends can be in a straight line or at 90 degrees to each other, or at any desired angle.If you have a special need for tension springs, our experienced engineers will design (including load and service life and other characteristics) and manufacture products that meet your company's needs.
