A linear wave spring is a continuous wave forming in the shape of a long strip spring. A load-bearing device has roughly the same load and deflection characteristics.
Compared with stamping springs, linear springs use pre-tempered raw materials and rounded edges, and the load and elastic coefficient are more accurate and predictable, 50% better than stamping parts, and the elastic coefficient is stable within the allowable deformation range.
Linear spring has high reliability, excellent performance, no deformation, smooth surface, no pits, scratches, breaks, and other small defects. Stamped springs may have defects such as fatigue fracture and inaccurate loading in the subsequent manufacturing process. In terms of metallurgy, mechanical properties, and dimensional stability, linear springs can provide higher precision quality.
Linear wave spring is used to replace traditional round wire spring with their unique space-saving potential. The use of a wave washer also indirectly reduces the spring assembly space due to the reduced working height of the spring. Smaller installation sizes and less material application result in a significant cost reduction.
It is particularly suitable for applications requiring weight reduction and applications limited by a small installation space. Typical application areas include aerospace, precision machinery, hydraulic seals, and high-end motors.
Although wave washers are not very familiar to some people, you need to know that their scope of application is very wide. A wave spring is an elastic element with several peaks and valleys on a thin metal ring. Therefore, under normal circumstances, it is mainly used in occasions where the load and deformation are not large, the spring stiffness is required to be small and the axial preload must be applied. Therefore, they are especially suitable for some applications requiring weight reduction and some applications restricted by small installation space.
1. Different material composition.
The main disadvantage of carbon steel wave spring is that it is easy to rust, especially in high temperature and high humidity environment. Once rusted, the metal structure of the material corrodes, causing the material to deform and break. Therefore, if the ambient temperature and humidity of the product are high, a stainless steel wave washer should be selected.
2. The production process is different.
The production process of carbon steel material is to obtain the high hardness of the spring produced by the low hardness base material through quenching and tempering. This process results in poor toughness and low service life of carbon steel materials, and the phenomenon of overall spring fracture in practical applications. The stainless steel material is obtained by several calendering by a low hardness base metal mill.
3. Material price difference.
Since the stainless steel material has a chromium content of 16-18% and a nickel content of 6%-8%, the price is 2-3 times more expensive than carbon steel. The same specification of spring, stainless steel spring will be about 2 times more expensive than carbon steel spring.
The spring force of stainless steel spring is lower than that of carbon steel spring, the hardness is lower than that of carbon steel wire, but the service life is long; carbon steel spring wire is easier to rust than stainless steel spring wire, and has higher requirements for the use environment.
There are several common methods for surface treatment of springs, such as bluing, phosphating, electroplating, and electrophoresis.
Oxidation: Heat the spring to an appropriate temperature in air or chemicals to form a blue (or black) oxide film on the surface to improve the corrosion resistance and appearance of the wave spring.
Blackening: The same as the oxidation principle, the spring is heated in the air or directly immersed in a concentrated oxidizing solution to produce a very thin oxide film on the surface of the wave washer. Material protection technology.
The surface of the wave spring should be smooth, no rust, no burrs, no cracks, and a uniform oxide layer.
