Introduction to Wave Springs
Wave springs, also known as wave springs, are thin annular elastic metal components consisting of several wave crests and wave troughs. This product is made of high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al) and stainless steel SUS304/SUS316/SUS631, which are heat-treated by specific methods and have a hardness generally controlled between HRC44-55. The surface is blackened and has good elasticity. Wave springs are widely used in the motor, machinery, hydraulic equipment, automotive and other industries. They are mainly installed in the bearing chamber or hole with appropriate specifications, with a small installation space, and have the special function of reducing noise and vibration.
Surface treatment
Wave springs are divided into two types: L/LM series wave springs and LS/LMS series wave springs.
The L/LM series are continuously wound wave spring with alternating peaks and troughs. The characteristics of this series of I wave springs are that they can provide ideal elasticity in a small installation space, saving up to 50% of space compared with conventional spiral springs.
The LS/LMS series are wave springs with alternating peaks and troughs and flat rings at both ends. In addition to the advantages of the L/LM type wave springs, the LS/LMS type has more evenly distributed elasticity because of the flat rings at both ends of the wave peaks. This type of wave spring is particularly suitable for environments where there are holes at both ends of the installation space, as the wave peaks can easily fall into the holes and become inoperable.According to processing technology: punched wave springs and wound wave springs.
Characteristics of Wave Springs
1. Material composition is different
The main disadvantage of carbon steel springs is that they are easy to rust, especially when used in high temperature and high humidity environments. When the ambient temperature and humidity are high, stainless steel springs should be used.
2. Different production techniques
The production process of carbon steel material is to obtain the high hardness of the production spring by quenching and tempering the base material with low hardness. This process leads to poor toughness of the carbon steel material and lower service life. In practical applications, there will be a whole spring. The phenomenon of fracture, the stainless steel material is obtained by the low hardness base metal rolling mill through several times to obtain the thickness and hardness required for the production of springs, and also obtains good toughness, which will eventually lead to a better service life than carbon steel springs. At the same time, the performance is more stable.
3. Material price difference
Because the content of chromium in stainless steel spring material accounts for 16-18%, and the content of nickel accounts for 6%-8%, the price is also 2-3 times more expensive than carbon steel. For springs of the same specification, stainless steel springs will be more expensive than carbon steel springs. The price will be about 2 times more expensive.
The spring force of stainless steel is lower than that of carbon steel spring, the hardness of stainless steel spring is lower than that of carbon steel wire, but the service life is longer; carbon steel spring is easier to rust than stainless steel spring, and it has higher requirements on the use environment.
The material section of the spiral carbon stainless steel multy turn wave spring should preferably be a circular section. Square and rectangular section materials have strong bearing capacity, good impact resistance, and can miniaturize the spring, but the source of materials is small. And the price is high, except for special needs, generally try not to use this material. In recent years, the development of rolling flat steel wire instead of trapezoidal steel wire has achieved good results.
Spring materials that work at high temperatures require good thermal stability, relaxation or creep resistance, oxidation resistance, and corrosion resistance to certain media.
