Unusual applications for wave springs

Unusual applications for wave springs

It may come as a surprise that top artists such as Noel Gallagher, Stevie Wonder and Madonna have performed on stage and in the studio with wave springs. When examining potential uses for wave springs, aerospace, automotive and medical applications are usually the first that come to mind – not live music. Here Justin Lawrence, applications engineer at TFC, explores three of the more unusual applications for wave springs.

Adhesives assure hydraulic systems

Adhesives assure hydraulic systems" reliability for 25 years

A gigantic Berg Propulsion propeller with a diameter of more than nine metres dwarfs the men standing next to it and at every stage of its manufacture, Loctite engineering adhesives from Henkel have an important part to play. Loctite threadlockers and thread sealants secure assemblies in the hydraulic systems in the propeller hub. The systems have to be pressure resistant and threaded assemblies immune from vibration loads.  Indeed, a minimum of 25 years of reliable service is the expected norm.

Over-specification of threaded fasteners

Over-specification of threaded fasteners

Ultimately, one can never know completely how a fastener will function in-situ until you try it which is why accelerated aging trials and extended excess load tests are frequently performed to ascertain a realistic safety margin. Guidelines from hard-won experience can normally be accessed, but sometimes an unusual situation needs to be evaluated or perhaps a replacement of the exact same type is simply not available.
