Abstract:
(EN) This divided-type mechanical seal comprises first and second seal ring holders (3, 5) divided in two in a radial direction, and first and second seal rings (4, 5) divided in two in the radial direction. Divided portions (3A, 3B) of the first seal ring holder (3) and divided portions (4A, 4B) of the first seal ring (4) are linked by first elastic members (18A, 18B) and first interlocking means (19A, 19B) so that the axial relative positions of the divided portions are fixed, and divided portions (5A, 5B) of the second seal ring holder (5) and divided portions (6A, 6B) of the second seal ring (6) are linked by second elastic members (20A, 20B) and second interlocking means (21A, 21B) so that the axial relative positions of the divided portions are fixed.
(FR) L'invention concerne un joint mécanique de type divisé comprenant des premier et second supports de bague d'étanchéité (3, 5) divisés en deux dans une direction radiale, et des premier et second anneaux d'étanchéité (4, 5) divisés en deux dans la direction radiale. Des parties divisées (3A, 3B) du premier support de bague d'étanchéité (3) et des parties divisées (4A, 4B) de la première bague d'étanchéité (4) sont reliées par des premiers éléments élastiques (18A, 18B) et des premiers moyens d'interverrouillage (19A, 19B) de telle sorte que les positions relatives axiales des parties divisées sont fixes, et des parties divisées (5A, 5B) du second support de bague d'étanchéité (5) et des parties divisées (6A, 6B) de la seconde bague d'étanchéité (6) sont reliées par des seconds éléments élastiques (20A, 20B) et des seconds moyens de verrouillage mutuel (21A, 21B) de sorte que les positions relatives axiales des parties divisées sont fixées.
(JA) 分割型メカニカルシールは、径方向に二分割された第一及び第二シールリング保持体(3,5)と、径方向に二分割された第一及び第二シールリング(4,5)とを具備するもので、第一シールリング保持体(3)の分割部分(3A,3B)と第一シールリング(4)の分割部分(4A,4B)とが第一弾性部材(18A,18B)及び第一係止手段(19A,19B)により軸方向の相対位置を一定とする状態で連結されると共に、第二シールリング保持体(5)の分割部分(5A,5B)と第二シールリング(6)の分割部分(6A,6B)とが第二弾性部材(20A,20B)及び第二係止手段(21A,21B)により軸方向の相対位置を一定とする状態で連結されている。
