- Coil spring: also known as coil spring. These springs get their name from the coiled ends. These springs store energy and can easily resist tension between two objects. Due to their shock absorbing properties, coil springs are mounted on railway bogies. Due to their shock-absorbing qualities, helical springs are also regularly used in various complex industrial applications;
- Conical springs: These springs are also known as conical springs or conical springs. The coils of these springs feature a tapered shape at the tapered end. Used in applications such as electric contacts or buttons;
- Disc Spring: A disc spring is basically a conical disc that is loaded in the axial direction. These springs are used as a single disc or stacked with multiple discs as required. These springs are considered ideal for industrial applications where large and small deflections are required;
- Clock Springs: These springs are also called power springs and are characterized by a helical damage shape. Springs are designed to expand naturally. This expansion creates a small circular motion, also known as torque. Once the spiral shape is exhausted, the clock spring will return to the clock shape. These springs consist of flat coiled strips that are tightly wound together in the shape of a snail. Clock springs are used when multiple torsion springs are required to rotate in an application;
- Flat Springs: These springs get their name from the flat shape with a height, width and thickness ratio. Depending on the application requirements, these springs are available in various sizes. Cantilever springs, leaf springs and other varieties are the most popular variants in this category. These springs are mainly used in the automotive industry;
- Corrugated Springs: These springs are distinguishable due to their compact design of corrugated size. Typically, corrugated springs are used in compact size applications. Corrugated springs are replacing coil springs in many industrial applications. Bellows springs are also suitable for applications with lower installation dimensions;
- Hourglass Springs: These springs have a smaller diameter at the center and wider edges, similar to an hourglass. Known as recessed springs, these springs are ideal for high-load applications.
The main function of wave spring:
- Control the movement of machinery, such as valve springs in internal combustion engines, control springs in clutches, etc.
- Absorb vibration and impact energy, such as buffer springs under automobiles and train carriages, vibration-absorbing springs in couplings, etc.
- Store and output energy as power, such as clock springs, springs in firearms, etc.
- Used as a force measuring element, such as a force measuring device, a spring in a spring balance, etc. The ratio of the load to the deformation of the spring is called the spring stiffness, and the higher the stiffness, the stiffer the spring.
A wave spring is a thin annular elastic metal element composed of a plurality of wave crests and troughs, which is referred to as a wave spring for short. A single turn wave spring is an elastic element with several wave peaks and troughs on a metal ring, while a multi-layer wave spring looks similar to a cylindrical coil spring composed of many single-layer wave springs.
Wave springs are widely used in motors, textile machinery, machinery manufacturing, petrochemicals, hydraulic equipment, automobiles and other industries. It is mainly installed in the bearing chamber or hole suitable for the specification (nominal size), the installation space is small, and it has special functions of reducing noise and vibration, and is suitable for occasions with large strokes and small loads.
Compared with ordinary helical compression springs, at least half of the space can be saved when bearing similar loads. The overall volume of the equipment can be reduced and the cost can be saved. Ideal for places where axial space is limited. The use requirements of different loads can be met by changing the thickness and width of the material or making two or three layers of overlapping wave springs.
The wave spring acts on occasions where the load and deformation are not large, and the spring stiffness is required to be small and the axial preload is required. However, during use, the wave spring will fail due to some reasons, thus affecting the normal operation and use of the equipment.
Causes of wave spring failure generally include:
First, the material for making the spring, the spring made of the surface-strengthened material will have a longer service life than the untreated one. Defective materials will also affect the service life of the spring, and yes, the spring will fail prematurely.
Second, the spring temperature. The wave spring has strong elasticity, conductivity and wear resistance at normal temperature, but as its temperature increases, the elasticity of the spring will gradually decrease, and it will gradually become fatigued and lead to failure.
