Abstract

Un joint mécanique (100) comprend une partie fixe (3) comprenant un réceptacle (5) et une première bague d’étanchéité (30) disposée sur ledit réceptacle (5), une partie rotative (4) comprenant un manchon (9) et une seconde bague d’étanchéité (40) disposée sur le manchon (9), une coupelle (6) montée à l’intérieur du réceptacle (5) avec possibilité de coulissement dans la direction axiale, un joint d’étanchéité statique (7) logé dans la coupelle (6), et un ressort (8) comprimé axialement entre le réceptacle (5) et la coupelle (6). Le ressort (8) comprend une première extrémité (80) retenue sur la coupelle (6) avec des premiers moyens de retenue (V1) et une seconde extrémité (81) retenue sur le réceptacle (5) avec des seconds moyens de retenue (V2) de telle sorte que ledit ressort (8) s’oppose à une rotation de la coupelle (6) par rapport au réceptacle (5).
