Classification and basic use of springs

发布时间:2020-6-6 21:35:53    浏览:24

The spring can be divided into compression spring, extension spring, torsion spring and bending spring according to the mechanical properties; spiral spring, scroll spring, plate spring, dish spring, ring spring and special spring according to the shape; cold coil spring and hot coil spring according to the manufacturing process; According to the material, it can be divided into metal spring, plastic spring, rubber spring and other material springs.


The main functions of the spring are:


1、 Control the movement of machinery, commonly including the control spring in the clutch and the valve spring in the internal combustion engine;


2、 Absorbing vibration and impact energy, the common ones are sofa seat spring, buffer spring under train carriage and vibration absorption spring in coupling, etc;


3、 Store and output energy as power, commonly clock spring, gun spring, etc;


4、 Force measuring element, force measuring device, spring scale, etc. The spring also has measurement function, reset function, driving function, buffering function, sounding function and pressing function.


Compression spring mainly bears pressure when it works, and has the function of resisting and buffering pressure. It is widely used in machinery.


The tension spring mainly bears the tension when it works, which is used for the reset of mechanism and widely used in machinery.


The torsion spring mainly bears the torsion moment when it works and has the ability of resisting the torsion. It is often used in the clamping of mechanism.


Plate spring is mainly used to bear pressure when working, mainly for shock absorption, commonly used in the suspension mechanism of automobile and tractor.


Plane scroll spring is mainly used to store energy when it works, and is widely used in clocks, instruments and experimental equipment.


The Belleville spring mainly bears the pressure when it works, and is widely used in the heavy mechanical equipment with large impact force.
