The Functions and Advantages of the Wave Springs

Sep. 13, 2021

The wave spring is a thin ring-shaped elastic metal element composed of a plurality of wave crests and valleys, which is called wave spring for short. A single-layer wave spring is an elastic element with a number of crests and valleys on a metal ring, while a multi-layer wave spring appears to be composed of many single-layer wave springs and is similar to a cylindrical spiral spring.

Do you know the functions and advantages of the wave springs? As a wave springs supplier, I'd like to share it with you.

Wave springs are widely used in motors, textile machinery, machinery manufacturing, petrochemicals, hydraulic equipment, automobiles and other industries. The main installation The special function of small vibration is suitable for occasions with large stroke, medium and small load.

The Main Functions of Wave Springs


① Control the movement of machinery, such as valve springs in internal combustion engines, control springs in clutches, etc.


② Absorb vibration and impact energy, such as buffer springs under cars and trains, and vibration-absorbing springs in couplings.


③ Store and output energy as power, such as clock springs, springs in firearms, etc.


④ Used as a force measuring element, such as a dynamometer, a spring in a spring scale, etc. The ratio of spring load to deformation is called spring stiffness. The greater the stiffness, the harder the spring.


The Advantages of Wave Springs


Compared with ordinary spiral compression springs, wave springs can save at least about half of the space when subjected to similar loads; wave springs can reduce the overall volume of the equipment and save costs; wave springs are very suitable for places with limited axial space; wave springs can pass Change the thickness and width of the material or make two or three overlapping wave springs to meet the requirements of different loads.


The wave spring acts on the occasions where the load and deformation are not large, and the spring stiffness is small and the axial preload is required.

However, during use, the wave spring will fail due to some reasons, which will affect the normal operation of the equipment.


Causes of the Failure of the Wave Spring


Material of the Wave Springs

Springs made of surface-strengthened materials have a longer service life than untreated materials. Defective materials will also affect the service life of the springs, and the springs will fail in advance due to fatigue.


Springs Temperature

Wave springs have strong elasticity, conductivity and wear resistance at normal temperature, but as their temperature rises, the elasticity of the spring will gradually decrease, and it will gradually become fatigued and lead to failure.
