If you need to customize the spring, this article will teach you a simple understanding of the spring classification
According to the dynamic action of the spring, it can be divided into:
- Control the movement of mechanical equipment, such as gate valve springs in gas turbines, control springs in clutch, etc.
- Digest and absorb shock and impact kinetic energy, such as the cache spring under the car and high-speed rail car, and the vibration absorption spring in the shaft connector.
- Store and output kinetic energy as driving force, such as clock springs, mechanical springs, etc.
- Used as force measuring components, such as force gauges, springs in spring scales, etc. The ratio of the load to the deformation of the spring is called the spring stiffness, and the greater the bending stiffness, the harder the spring.
Spring according to the support elasticity, can be divided into:
- Tension spring
- Compression spring
- Torsion spring
- Bending spring
Spring according to the shape classification, can be divided into:
1 cylindrical coil spring
Also known as cylindrical spiral compression springs, divided into the following categories:
1.1 Cylindrical helical compression spring with round section
The characteristic line is linear, the structure is simple, it is the most widely used spring, and it is mostly used in mechanical equipment for buffering, reducing vitality, energy storage, and control movement.
1.2 Rectangular section cylindrical helical compression spring
The characteristic line is closer to the straight line and the stiffness is closer to the constant. Under the same space condition, the cylindrical helical compression spring with rectangular section has higher stiffness and more energy absorption than that with circular section.
1.3 Cylindrical helical compression spring with flat section
Compared with circular section cylindrical spiral compression spring, it has large storage energy and large compression amount, and is widely used in engine valve, clutch, automatic transmission and other equipment with relatively small installation space.
1.4 Cylindrical helical compression springs with unequal pitch
The characteristic line is changed from linear to gradually increasing, and the natural vibration frequency is variable, which can eliminate or alleviate the influence of resonance well, and is mostly used in high-speed variable load equipment.
1.5 multi-strand cylindrical helical compression spring
The raw material for processing is a wire rope screwed into a thin steel wire, when not under load, the contact between the steel wire rope is relatively loose, when the external load reaches a certain degree, the contact is tight, then the spring rigidity increases, so the characteristic line of the multi-strand coil spring has a break point. Compared with the ordinary cylindrical helical spring of the same section material, the strength is higher and the damping effect is larger. Widely used in weapons and aircraft engines.
2 Cylindrical helical stretch spring
The performance and characteristics are the same as that of the round section cylindrical helical compression spring, which is mainly used for the occasion of tensile load.
3 cylindrical spiral torsion spring
Bear torsion load, mainly used for compression, energy storage, transmission system in the elastic link, with linear characteristic line; Widely used in dynamometer and forced air valve closing device.
4 Conical coil springs
Also known as variable diameter coil spring.
The characteristic line position is nonlinear, the vibration frequency is variable, the ability to eliminate and alleviate resonance is stronger than the equal pitch compression spring, the spring has compact structure and good stability, and is used in the suspension spring of heavy vibrating screen and automobile transmission.
5 Cochlear coil spring
Compared with other springs, spiral coil springs can absorb more energy in the same space, and the friction between the plates can be used to attenuate vibration. The plant is used in steam and water piping systems in power plants.
6 Torsion bar spring
High requirements for raw materials and manufacturing accuracy. It is mainly used in automobile suspension spring, auxiliary spring of valve in internal combustion engine, and air spring, auxiliary spring of voltage regulator.
7 Butterfly spring
The ordinary dish spring has strong capacity of cushioning and damping. Different characteristic lines can be obtained by using different combinations. It can be used in pressure relief valves, automatic changeover devices, reset devices and clutches.
8 ring spring
Widely used in the need to absorb large energy but space size is limited occasions, such as: machine traction device spring, crane buffer spring, cannon buffer spring, aircraft brake spring and so on.
9 plane scroll spring
It is coiled by a small size metal belt and is widely used for measuring components and pressing components.
The clockwork is reliable and easy to maintain, and is widely used in timing instruments and time control devices, such as clocks, recording instruments, household appliances, etc. It can also be used as a power source in toys.
10 Blade spring
Blade spring is a rectangular section of metal, mainly used in the load and deformation are not large occasions. For example: detecting instruments or automatic devices in the sensitive components, electrical contact points, ratchet mechanism ratchet claws, positioners and other pressure springs and support or guide rails.
11 Leaf springs
The leaf spring is composed of multiple spring plates. It is widely used in automobile, tractor and train as suspension device, lifting buffer and damping, and also used in various mechanical products as damping device, with high stiffness.
12 Pressure spring tube
Under the pressure of the fluid, the end displacement is generated, and the displacement is transmitted to the pointer through the transmission mechanism, which is used for pressure gauges, thermometers, vacuum meters, level meters and flowmeters.
