Abstract

L’invention concerne un dispositif de transmission et de transformation de mouvement (10), comprenant un premier système de liaison hélicoïdale (120) qui connecte un arbre d’entrée (100) monté pivotant sur un support à un arbre intermédiaire (200) monté coulissant sur le support. Selon l’invention, il est en outre prévu un second système de liaison hélicoïdale (320) qui connecte l’arbre intermédiaire à un arbre de sortie (300) qui est monté pivotant sur le support, et le premier système de liaison hélicoïdale présente un pas (P120) différent du pas (P320) du second système de liaison hélicoïdale. Figure pour l’abrégé : Fig.2The invention relates to a motion transmission and transformation device (10), comprising: a first helical connection system (120) which connects an input shaft (100) pivotally mounted on a support to an intermediate shaft (200) mounted sliding on the support. According to the invention, a second helical connection system (320) is further provided which connects the intermediate shaft to an output shaft (300) which is pivotally mounted on the support, and the first helical connection system has a pitch (P120) different from the pitch (P320) of the second helical connection system.
