Abstract

L'invention a pour objet un joint sphérique pouvant fournir un couple de frottement rotatif stable. Des parties de nervures verticales déformées par compression contre une chambre interne (21) dans l'état emmanché à force d'un siège de bille (4) vers la chambre interne (21) et par formation de dégagements entre la partie supérieure de la surface périphérique externe (45) du siège de bille (4) et la surface périphérique interne (31) de la chambre interne (21) sont formées sur la surface périphérique externe du siège de bille (4) au niveau d'une position inférieure à sa position correspondant à l'équateur de la chambre interne (21) d'une douille (3). Etant donné que les dégagements sont réduits par la déformation verticale du siège de bille (4) lorsque la douille (3) est déformée par calfeutrement, une tolérance dimensionnelle entre la chambre interne (21) et la surface périphérique externe (45) du siège de bille (4) peut être absorbée. Par conséquent, le couple de frottement rotatif stable du joint sphérique (1) peut être fourni en réglant facilement le degré de contact par compression de la surface coulissante (41) du siège de bille (4) sur une partie de bille (15) pour éliminer les variations de contact par compression.
