Springs use their own deformation to generate forces

- Mar 17, 2018 -

Springs use their own deformation to generate forces or mechanical parts that store energy.

 

Its main functions are:

1. Control of mechanical movements, such as valve springs in internal combustion engines and control springs in clutches. 2. Absorb vibration and impact energy, such as cushioning springs in cars, train cars, vibration absorbing springs in couplings, etc. 3. Storage and output of energy as a power, such as clock springs, springs in firearms, etc. 4 .used as a force measuring element, such as a force measuring device, a spring in a spring balance, etc. The ratio of the load and the deformation of the spring is called the spring stiffness. The greater the stiffness, the stiffer the spring.

 

According to the nature of the force, the spring can be divided into tension spring, compression spring, torsion spring and bending spring, and the shape can be divided into a coil spring, disc spring, annular spring, plate spring, plane scroll spring, and torsion bar spring. Ordinary cylindrical coil springs are widely used due to their simplicity of manufacture, their ability to be manufactured in various types depending on the loading conditions, and their simple structure. Spring manufacturing materials generally should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, commonly used carbon spring steel, alloy spring steel, stainless steel spring steel and copper alloy, nickel alloy. Springs are produced by the cold roll method and the hot roll method. The cold coil method with a spring wire diameter of less than 8 mm and the hot coil method with a diameter of more than 8 mm. Some springs are also subjected to strong pressure or shot peening after they are made, which can increase the bearing capacity of the spring.

 

The spring is a kind of elastic component widely used in the mechanical and electronic industries. When the spring is loaded, it can produce a large elastic deformation, transform mechanical or kinetic energy into deformation energy, and after unloading, the deformation of the spring disappears and returns to its original state. Deformation can be converted into mechanical or kinetic energy.

 

The main functions of the spring are: 1. force measurement, such as spring scales. 2. control movements, such as clutches, brakes, and valve control springs; 3. damping and buffering, such as springs for shock absorbers, shock absorbers, etc.; 4. Energy storage or transmission, such as clocks, meters, and springs on automatic control mechanisms.

 

There are many types of springs, common are compression springs, extension springs, torsion springs, and wire molding.
