Abstract

La présente invention concerne un ressort Belleville à ouverture externe comprenant un corps de ressort Belleville, le corps de ressort Belleville étant pourvu d'un trou de montage (1) au milieu ; une surface supérieure d'une partie anneau interne (2) est inférieure à celle d'une partie anneau externe (4), et une surface inférieure de la partie anneau interne (2) est inférieure à celle de la partie anneau externe (4) ; une partie anneau intermédiaire (3) et la partie anneau externe (4) sont pourvues d'une pluralité de premières fentes radiales (5) réparties uniformément du centre du trou de montage (1) jusqu'à une périphérie externe, les premières fentes (5) sur une face externe de la partie anneau externe (4) étant pourvues d'une ouverture (10) qui est plus large au niveau de la face externe, une première structure d'arc circulaire (7) étant au niveau d'une face interne de la première fente (5), la partie anneau externe (4) présentant une deuxième structure d'arc circulaire (8) s'étendant en arc vers l'extérieur ; et une seconde fente (6) étant disposée entre des premières fentes adjacentes (5), la seconde fente (6) étant une fente radiale du centre du trou de montage (1) jusqu'à la périphérie externe, la seconde fente (6) ne pénétrant pas dans la partie anneau interne (2) et la partie anneau externe (4), et deux extrémités de la seconde fente (6) constituant une troisième structure d'arc circulaire (9). Le ressort à ouverture externe a une forte capacité élastique et présente un bon effet d'utilisation.
