The torsion spring (torsion spring) utilizes the principle of the lever, and has great mechanical energy by twisting or rotating the elastic material with soft material and high toughness. It is a spring that is subjected to torsional deformation. Its working part is also a circle, either closely or separately. The end structure of the torsion spring is a torsion arm processed into various shapes, from single to double twist, and even to various deformations of the torsion bar, which can be molded according to design. Torsion springs are often used in mechanical balance mechanisms and are widely used in industrial production such as automobiles, machine tools, and electrical appliances.
Compression springs (compression springs) are helical springs that withstand axial pressure. Springs are generally divided into equal-pitch springs and variable-pitch springs. Compression springs have the following shapes: cylindrical, conical, convex, and concave, and a small amount. Non-circular, etc., there is a certain gap between the ring and the ring of the compression spring. When subjected to an external load, the spring shrinks and deforms, and the deformation energy is stored.
. Variable-pitch springs are becoming more and more popular. They are not just equal-pitch springs. Variable-pitch springs can play different roles in different environments.
