The main role of the spring What are the
(1) control the movement of machinery, such as internal combustion engine valve springs, clutch control spring.
(2) absorption of vibration and impact energy, such as cars, train carriages under the buffer spring, coupling vibration absorber spring.
(3) storage and output of energy as a driving force, such as watches and clocks, springs, firearms in the spring.
(4) as a force measuring components, such as dynamometer, spring scale spring. Spring load and deformation ratio is called spring stiffness, the greater the stiffness, the harder the spring. Spring is widely used in the mechanical and electronic industries as a kind of elastic element, the spring can produce greater elastic deformation under load, the mechanical or kinetic energy into deformation energy, and after unloading deformation of the spring disappears and restore the status quo, the Deformation can be converted into mechanical work or kinetic energy.
(5) measurement function We know that, within the elastic limit, the spring elongation (or contraction) is proportional to the external force. The spring scale is made of this property.
(6) pressing function Observation of a variety of electrical switches will find that the two contacts in the switch, there must be a head fitted with springs to ensure that the two close contact, is a good conduction. If the contact is bad, the contact resistance becomes larger, the heat generated by the current through the larger, in severe contact with the metal will melt. The two metal posts of the bayonet lamphead are fitted with springs for good contact. As for the center metal plate of the screw cap and the metal plate of the plug socket are all reeds, the function is to keep both sides in close contact With the good. In the tape cassette, there is a piece of phosphor bronze reed, the use of its bending deformation caused by the elastic head in close contact with the tape. In the stapler has a long coil spring its role on the one hand is the top tight staples, on the other hand is when the front of the nail was pushed out, you can put the back of the nail to the front for the comfort of the introduction of nails, In this way, you can automatically push a pin to the front, until all the nail so far. Many machines automatically feed, automatic rifles in the automatic loading of the bullets rely on the spring of this function. In addition, clips like clip-on clothes, ball-point pens, and pens on the pens are clamped to the clothes by the pressing function of the springs.
(7) reset function The spring under the action of external force deformation, remove the external force, the spring will be able to restore the state. Many tools and equipment are using the nature of the spring to reset. For example, many of the doors of the building are fitted with a reset spring hinge on the people out, the door will automatically reset. People also made use of this feature automatic umbrella, automatic pencil and other supplies, is very convenient. In addition, a variety of buttons and buttons are also the return spring.
(8) drive mechanical clocks, winding toys are driven by tightening the winding. When the spring is tightened when the winding bending deformation, storage of a certain elastic potential energy. After release, the elastic potential energy into kinetic energy, driven by the transmission rotation. The toy guns and starting guns and military guns also work with one of the properties of the spring.
(9) the buffer function in the locomotive between the car frame and the wheel with the spring, the use of spring elasticity to slow down the vehicle bumps. Vibration sound function When the air from the harmonica, accordion in the spring hole flow, the impact of reeds, reed vibration sound.
