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.
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 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:
The choice of material will depend on the specific requirements of the application, including the operating conditions, load requirements, and desired service life.
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.
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.
