A Wave Spring Washer is a mechanical washer that is composed of flat wire that is formed into a wavy or oscillating pattern. The design of the wave allows the washer to absorb the force of the axial wind, provide a force of elasticity, and compensate for the variations in dimensions of the components that are assembled. Compared to traditional flat washers or coil springs, 波形弹簧 washers have a smaller volume in the axial direction, which makes them ideal for compact assemblies that require preload control, damping, or compensation for vibrations.
