MUM Clavetage sur fraiseuse universelle (keying shaft) sous-titre FR

Dans un atelier de fabrication mecanique , le clavetage est presque quotidien pour une fraiseuse universelle, et c'est pour cela que je montre dans cette video d'un clavetage normalisé sur un arbre ø50 14mm profendeur 5,5mm et une clavette de 14mm/9mm. WIKI: Généralement utilisé pour assembler un arbre et un pignon ou deux arbres ensemble, il nécessite un usinage précis des pièces ; le clavetage entraîne une concentration de contrainte et donc une faiblesse de l'arbre. La clavette est soumise à des contraintes de cisaillement. Un matage (déformation plastique sous l'effet de chocs) peut se produire si les efforts sont trop importants ou si le jeu de montage est trop important. https://fr.wikipedia.org/wiki/Clavett... https://fr.wikipedia.org/wiki/Clavetage https://en.wikipedia.org/wiki/Key_(en...)
