Borrelly Diaphragm Washers
Diaphragm washers are a special case of Belleville disc springs.
The diaphragm washer can deliver a wide range of elasticity curves and can handle large loads. Thus, it can behave as a multi-turn spring wahser, while achieving the elasticity curve you need to resolve your challenge.
Technical description
Combinations of localized stresses at the base of the teeth, thanks to accurate sizing, enables to obtain a wide range of elasticity curves.
Thus, it’s possible to have a spring that stores forces when it relaxes, instead of when it compresses.
Diaphragm washers can also deliver greater deflections (in terms of elastic deformation) without much variation in force. This feature is of particular interest when one is looking for a stable preload over a broad tolerance range.
Thus, diaphragm washer delivers elasticity curves perfectly adapted to the problem to be solved.
Our Engineering & Design Department can study any geometry of Diaphragm washers according to your specifications, for technical and precise applications in materials even under the most severe environments. Our production workshops can supply you with these washers, from prototypes to very large serie.
We study your needs to design your custom spring washers.
