Abstract

Ce joint homocinétique à bille fixe 3 équipé d'un élément de joint extérieur 31, d'un élément de joint intérieur 32, de huit billes 33 et d'une cage 34. Le centre de courbure O31d de la rainure de piste 31d de l'élément de joint extérieur 31 et le centre de courbure O32e de la rainure de piste 32e de l'élément de joint intérieur 32 sont chacun décalés du centre de joint O(f) de distances égales sur des côtés opposés du centre de joint O(f) dans la direction axiale. Le rapport PCDBALL/DBALL du diamètre de cercle primitif PCDBALL des billes 33 et du diamètre DBALL de chaque bille 33 est de 3,70–3,87. Le rapport W1O/DBALL de la longueur dans la direction axiale W1O depuis le centre de joint O(f) vers la face d'extrémité côté ouverture de la partie d'embouchure 31a de l'élément de joint extérieur 31 et du diamètre DBALL de chaque bille est de 0,35–0,52.
