Multiple Belleville washers may be stacked to modify the spring constant or amount of deflection. Stacking in the same direction will add the spring constant in parallel, creating a stiffer joint (with the same deflection). Stacking in an alternating direction is the same as adding springs in series, resulting in a lower spring constant and greater deflection. Mixing and matching directions allow a specific spring constant and deflection capacity to be designed. http://en.wikipedia.org/wiki/Belleville_washer

Din punct de vedere constructiv se caracterizeaza prin simplitate si robustete, conferind legaturii o rigiditate mare (rigiditatea sa la incovoiere si torsiune depaseste cu mult rigiditatea elementelor cuplate). Ca urmare, socurile si vibratiile se transit fara atenuare intre elementul conductor si condus. Acestor cuplaje li se prescriu conditii severe de aliniere (centale) deoarece imperfectiunile de executie si montaj au ca efect suprasolicitari in arbori si lagare. http://www.referat.ro/referate/Reconditionarea_cuplajelor_9c...
