Flat-wire wave springs, an increasingly accepted alternative spring technology, come in single- and multi-turn versions that install easily in a variety of preloading and power transmission applications. Read on for some useful wave spring tips.
Multi-turn wave springs easily locate in bores and are easier to install than multiple disc springs. The compact design of wave springs may also allow designers to save money by loosening manufacturing tolerances.
Wave springs are easily customized.
Designers can dial in the wave-spring stiffness required for their design by specifying wire thickness and cross-sectional dimensions, material selection, and the number of waves and turns per spring.
Wave springs do not require custom tooling.
When a custom wave spring is the only way to meet design requirements, vertically integrated manufacturers can quickly alter the parameters of coiling equipment to produce the custom springs without tooling costs.
Wave springs work in non-magnetic applications.
Some medical imaging technologies and automotive sensors must transmit safety-critical signals without interference. Wave springs in non-magnetic alloys such as A286 stainless steel, beryllium copper, or Inconel X-750 are available for these applications.
Wave springs work in extreme environments.
In other applications, components must withstand extreme environments such as high temperatures, moisture, and corrosive chemicals. So, durable wave springs have been designed with high-performance alloys like Inconel, Elgiloy and Hastalloy.
