Abstract

Cette invention se rapporte à un joint de cardan à vitesse constante de type coulissant pouvant être assemblé avec une maniabilité améliorée et pouvant être obtenu sans augmentation du poids du joint ni réduction de la durabilité d'une bague intérieure. Dans une cage (5), le centre axial (A) d'une surface périphérique intérieure sphérique (18) se situe sur le côté intérieur depuis le centre axial (B) d'une surface périphérique extérieure sphérique (19). Une surface d'extrémité intérieure (15) de la bague intérieure (3) et une surface inférieure intérieure (16) d'une bague extérieure (2) sont adaptées de sorte qu'elles puissent se trouver en contact de surface l'une avec l'autre, lorsqu'un arbre (9) est ajusté par pression dans un trou d'arbre (21) de la bague intérieure (3). Une partie de contact de surface (25), qui est une partie de la surface d'extrémité intérieure (15) de la bague intérieure (3) et vient en contact de surface avec la surface inférieure intérieure (16) de la bague extérieure (2), est formée comme une surface conique radialement inclinée de α˚ vers le côté du centre de la bague intérieure. Une partie de contact de surface (26), qui est une partie de la surface inférieure intérieure (16) de la bague extérieure (2) et vient en contact de surface avec la surface d'extrémité intérieure (15) de la bague intérieure (3), est formée comme une surface conique ayant une correspondance de forme avec la partie de contact de surface (25) de la bague intérieure (3).
