Abstract

Un logement cintré réglable comprenant un premier corps tubulaire et un second corps tubulaire. Le second corps tubulaire s'étend télescopiquement dans le premier corps tubulaire et est maintenu en position axiale relative par une pièce filetée. Un manchon de verrouillage est prévu pour maintenir la position de rotation relative du premier corps tubulaire et du second corps tubulaire. Le manchon de verrouillage est couplé de manière non rotative avec et mobile de façon coulissante avec le second corps tubulaire entre une position de verrouillage et une position de réglage. Un contre-écrou est mobile sur la surface externe du second corps tubulaire et retient de manière sélective le manchon de verrouillage dans la position de verrouillage. Ce logement cintré réglable peut recevoir des arbres d'entraînement de plus gros diamètres, tout en permettant l'ajustement d'avoir lieu sans modification de la longueur totale du logement.
