PRODUCT PROPERTIES

Main Functions of the Spring:
1. Control mechanical movement. For example, valve springs in internal combustion engine, control spring in clutch, etc. 2. Absorb vibration and impact energy. For example, buffer springs under car and train carriages, vibration-absorption springs in couplings, etc. 3. Save and output energy as power. For example, clock springs, springs in machinery, etc. 4. Be used as force-measuring components. For examples, dynamometers, springs in spring scales, etc. The ratio of spring load to deformation is called spring stiffness. The greater the stiffness, the harder the spring. Spring is a kind of elastic element widely used in mechanical and electronic industries. Spring can generate large elastic deformation when it is loaded, and transform mechanical energy or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state. And transforms deformation energy into mechanical energy or motion. |
