Structural application and common faults of overlap wave spring

What are the functions and functions of overlap wave spring?

The overlap wave spring has the ability to save space. The overlap wave spring is an elastic element with several valleys in a thin metal ring. The main functions of the overlap wave spring are:

1. The valve spring of the internal combustion engine, the control spring of the clutch, etc. control the action of the machine.
2. Absorb the vibration and impact energy of buffer springs under automobiles and trains, couplings, and absorb springs, etc.
3. Springs in clocks, springs in firearms, etc. store and output energy as power.
4. When used as a weighing sensor such as a load cell or a spring of a spring scale, the ratio of the load to deformation is called the spring rigidity, and the greater the rigidity, the harder the spring.

Composition: Overlap wave spring refers to a sheet-shaped elastic metal element composed of multiple mountain valleys, which is referred to as a wave spring for short. A single-layer overlap wave spring is an elastic element with several crests on a metal ring, and a multi-layer wave spring looks like it is composed of many single-layer wave springs.

Overlap wave spring is widely used in motor, textile machinery, machinery manufacturing, petrochemical, hydraulic equipment, automobile and other industries. It is mainly installed in the bearing chamber or hole that meets the specification (nominal size). It has the advantages of small installation space, reduced noise and reduced vibration. special features of。

Compared with the ordinary overlap wave spring, when a similar load is applied, at least about half of the space can be saved; It can reduce the overall volume of the equipment and save costs; It is suitable for places with limited axial space. By changing the thickness and width of the material or making double or triple overlapping wave springs, it can meet the requirements of different loads.

The overlap wave spring works when the load and deformation are not large, the spring rigidity is small, and axial preload needs to be applied. However, when in use, the wave spring may fail for some reason, which will affect the normal operation and use of the equipment.

So, what is the reason for the failure of the overlap wave spring? Let us briefly analyze it. The causes of overlap wave spring failure are generally:

1. It is the material for making springs. Springs made of materials with surface strengthening treatment have a longer life than untreated ones. Defective materials will also affect the life of springs. Yes, springs will fail due to early fatigue.
2. The temperature of the spring, the wave spring has strong elasticity, electrical conductivity and wear resistance at normal temperature, but as the temperature rises, the elasticity of the spring gradually decreases, and gradually fails due to fatigue.

How to choose the manufacturer of overlap wave spring?

Wave springs has became a relatively common product now. Due to their multiple functions, it is favored by many people. Presumably,compared with the traditional wave spring, it has more advantages. Now wave spring has been well-received in the market, and many user are looking for manufacturer to cooperate with, so how to choose the right manufacturer? Next, I will briefly introduce it to you.

With the continuous increase of the demand, there are now many manufacturers. In this case, it is usually not easy to find a reputable manufacturer who can consistently supply high quality goods for you . And of course there are good and bad options in the market. For those who are not familar with the market, it is hard to choose. At this time, you just need to consider these aspects. When you evaluate a company, firstly, you need check the production qualifications of the manufacturers, see if they are real companies or unlicensed workshops, after that you should check their reputation in the industry by comparative analysis. Then it is more important to find out whether the quality of their products is up to standard. Besides, it is suggested to check whether the wave spring manufacturer has relevant quality certifications and whether there are quality problems. It is also necessary to know more about its background includes its history and company culture. The most convenient for you to check those information is through the Internet when you don’t have time in the early stage of market research. In fact, these basic information can usually be found on the Internet. And some customers will also leave reviews. If the wave spring manufacturers do not perform well, their reputation will be reflect that. Therefore, it is recommended that you research this in advance.

Of course, you can find some wave spring manufacturers with good reputation, and then make a comparison. Investigate the production situation of each wave spring manufacturer, as well as their production cycle. Ask clearly whether their orders can be delivered on time and whether their promise can be fulfilled well. After consulting all these clearly, when asking about the price of the wave spring, we still need to remind everyone here that when buying a product, don’t just care about its price blindly, and the quality should also be considered for improvement. It is not unreasonable to understand that you get what you pay for. Of course, we need to look at a few more companies and make multiple comparisons. Because the price is reasonable, the wave spring with guaranteed quality will not often have problems when it is used. Next, you should consult clearly whether the wave spring manufacturer’s supply price is lower than the market price. If you can meet these, then you can basically consider cooperation. If you need a relatively large amount, try to find time to visit the site. This will give you more peace of mind. As long as you master these little skills, then this matter is actually relatively simple.

Since 2012, Zhejiang Lisheng Spring Co., Ltd. has started to develop wave springs, wave spring washer, spiral retaining rings, constant section retaining rings and laminar seal rings. We have rich production experience and excellent product quality, if you are interested in our products, please feel free to contact us.
