Introduction:
Spring is an elastic element widely used in mechanical and electronic industries. When it is loaded, it can produce large elastic deformation and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original state, and the deformation energy is converted into mechanical work or kinetic energy.
Spring is actually an accumulator, which has the function of storing energy, but it can't release energy slowly. To achieve this function, it should be realized by "spring+large transmission ratio mechanism", which is more common in mechanical watches.
Ordinary cylindrical springs can be made into various types according to the load because of their simple manufacture, simple structure and wide application.
Springs were used a long time ago, and ancient bow and crossbow was two kinds of springs in a broad sense. Theoretically, the inventors of the spring water are Zheng Xuan, a scholar of the Eastern Han Dynasty in China, and robert hooke, a British scientist. Even though the helical compression spring appeared and was widely used in the17th century, Hooke's "Hooke's Law"-the elongation of the spring is proportional to the force, which accords with the physical description of the spring. According to this principle, the 1776 spring scale with spiral compression spring came out. Soon, the clockwork specially made for clocks and watches based on this principle was also invented by Hooke himself. It should be said that the spring that conforms to Hooke's law is the real spring.
