Custom High Precision Stainless Steel Serpentine Square Wire Wave Spring Wave Disc Spring
Description:
Multi turn wave springs, also known as coiled wave spring or scrowave spring, is a spring made up of pre-hardened flat wire in a process called on-edge coiling (also known as edge-winding). During this process, waves are added to give it a spring effect.
Multi Turn Wave Springs or Multi-Wave Compression Springs offer deflections beyond round wire springs and occupy less axial space.
Lispring Wave Springs (Flat Wire Compression Springs) offer the unique advantage of space savings when used to replace coil springs.
Although the spring industry is a very inconspicuous small industry in the machinery manufacturing industry, the role played by the spring will never be low. Industrial equipment has been widely used in China. Correspondingly, we also understand some new components with superior performance, multi turn wave springs is a relatively new elastic element. An ordinary single turn wave spring is an elastic element with several peaks and valleys on a metal ring. The multi turn wave springs seems to be composed of several ordinary single turn wave springs, the difference is that it is not simply superimposed, but processed through a special continuous winding process.
Multi turn wave springs to the peak type (tandem type): The spring force value is inversely proportional to the number of turns. It is mainly used for: large displacement, medium and low spring force requirements, and is a substitute for cylindrical springs. Nested type (parallel type): The force value of the spring is proportional to the number of turns. While generating a huge elastic force, it can also maintain all the accurate characteristics of the wave spring. Nested (parallel type) wave springs can be used in many places. Use instead of disc springs.
Multi turn wave springs are wound from thin sheet-like spring strips and are ideal for applications requiring reduced weight and limited installation space. Whether it is the free height of the spring or the working height, the multi turn wave springs are much lower than the conventional round wire coil springs; relatively speaking, in order to obtain the same spring force, the wave spring can save up to 50% of the installation space and 70% of the spring weight.
Multi turn wave springs are particularly suitable for applications requiring reduced weight and installation space. Typical applications include: aerospace, precision machinery, hydraulic sealing and high-end motors.
Features of multi turn wave springs
It is suitable for occasions with large stroke and small load.
Compared with ordinary helical compression springs, at least about half of the space can be saved when bearing similar loads;
It can reduce the overall volume of the equipment and save costs;
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.
Wave spring washers mainly include steel wave springs for single-layer motors and multi turn wave springs, among which multi turn wave springs are also called multi-layer wave washers. It is a multi-layer metal sheet ring and each layer of the ring has multiple peaks and valleys elastic metal elements, usually used in spacecraft, bearings, flow valves, pressure valves, clutches, vibration isolators, axial piston pumps, drives and other equipment.
Since the overall and working height of the wave spring is lower than that of conventional round wire springs, the space size of the components can be reduced by up to 50%. Lisheng wave spring is made of 17-7PH stainless steel, which has the characteristics of high tensile strength and fatigue resistance, and its high stress performance is better than that of carbon steel spring. The wave spring can be used in a working environment of up to 200°C. It has been passivated while maintaining its corrosion resistance, and its appearance is also very bright and beautiful.
Multi turn wave springs of different materials
Multi-turn wave springs can be made from a variety of materials, each with their own unique properties. Some common materials used to make multi-turn wave springs include:
Stainless Steel: This is a popular choice due to its corrosion resistance, durability, and ability to withstand high temperatures. It is also relatively low-cost compared to other materials.
Inconel: This is a nickel-chromium alloy that is highly resistant to corrosion and can withstand high temperatures. It is commonly used in aerospace and industrial applications.
Titanium: This is a lightweight, strong, and corrosion-resistant metal that is often used in aerospace and medical applications.
Phosphor bronze: This is a copper-tin alloy that is known for its good spring properties and corrosion resistance. It is commonly used in electronic and electrical applications.
-BeCu: (Beryllium Copper) it’s a copper alloy with high spring properties and corrosion resistance.
The choice of material will depend on the specific requirements of the application, including the operating conditions, load requirements, and desired service life.
Life of wave spring
The life of the wave spring is mainly related to the different compression amounts and the stress ratio of the material during the compression process of the wave spring during use. When used at the minimum working height, the normal service life is about 10,000 times. If you need to increase the service life of the wave spring, you need to reduce the amount of compression used. When it is reduced by more than 50%, the theoretical life can be increased to 1 million times.
Application of wave spring
As a load-carrying device, the wave spring can compensate for changes in assembly dimensions while performing its load function. When the wave spring is compressed to a gradual or momentary preset operating height, the load can be accumulated, resulting in an unlimited range of force values. The load is proportional to the deflection of the wave spring, giving it a precise spring constant. Wave springs only need a very small space in operation to exert their performance, so they are especially suitable for applications with limited axial or radial space, such as pressure relief valves, surface seals, slip clutches, bearing towels, fluid valves , oil valve, floating gear, positioning preload and other devices.
How to prevent corrosion of multi turn wave springs
Spraying paint: Coating a layer of protective paint on the center of the surface of multi turn wave springs is one of the main methods for spring anticorrosion. Mostly used for large and medium springs. Especially thermoformed springs and leaf springs. Common coating methods are painting and dipping. With the development of technology, new technologies such as electrostatic spraying will be developed in order to improve operating power, paint utilization and coating quality.
Oxidation treatment: The oxidation treatment of multi turn wave springs is also called blue or black. After oxidation treatment, protective magnetic iron oxide is produced on the surface of the spring, with a thickness of about 0.6-2um. Because the film is thin, there are many gaps, and the protection ability is poor. Therefore, oxidation treatment can only be used for spring corrosion protection in low corrosive media. Due to the low cost of oxidation treatment, simple process formula, high production power, and no influence on spring properties, it is widely used for surface anticorrosion of cold-formed small springs.
Electroplating: Electroplating is an effective method to obtain a protective layer on the metal surface, and it is also the main method for anti-corrosion treatment of multi turn wave springs. It has the characteristics of good adhesion, fine crystallization, small pores, uniform thickness, excellent physical, chemical and mechanical properties.
