Waveform spring is called wave spring for short; it is the elastic element which has several peak valleys on the thin metal ring. Which is characterized by small deformation that can bear large load, the spring force is the same as the traditional circular coil spring, but the working height is reduced by 50%.The unique advantages of the wave springs provide engineers with space-saving spring solutions that meet their needs in designing modern compact technology.
According to its structural characteristics, the wave spring is usually divided into the following three categories: (1) Single-layer wave spring; (2) Series wave spring; (3) Parallel wave spring.
Single-layer wave spring.The wave spring we produced including single-layer( open, closed ) wave spring. For short deflections and low-medium forces, they function with precision and dependability. These two types of Wave Spring permit radial expansion or growth in diameter within a cavity so that the ends are free to move circumferentially as the spring outside diameter grows during compression.
Parallel wave spring are pre-stacked in parallel from one continuous filament of flat wire. The need to stack individual springs for higher loads is no longer necessary. Parallel wave spring result in a spring rate that increases proportionately to the number of turns.
Series wave spring is made of a strip through the series wound processing method superimposed, according to the beginning and end can be 360 degrees contact it is divided into closed end to the top wave spring and the top wave spring, from the structure, The consistency of the peaks and troughs is maintained. Compared with the closed end to the top wave spring, the flat end to the top wave spring, because the end is flat, under stress, its force distribution is more uniform, and its matching components are subjected to more uniform spring force.
The excellent performance of the wave spring determines its wide range of uses. At present, wave spring is widely used in automobile, equipment manufacturing and aerospace industries.
