(FR) ACCOUPLEMENTS A PHASE VARIABLE
Abstract:
(EN) An assembly capable of varying the relative phase of rotation between a driving sprocket wheel (6) and a camshaft (1) comprises a carrier (8) fixed to the sprocket wheel and carrying compound idler bevel gears (B, E and C, D). The inner idler gears (E, D) mesh with a bevel gear (F) fixed to the camshaft (1) to impart rotation to the camshaft. The outer idler gears (B, C) mesh with a ring gear (F) carried by a sleeve shaft (2) which is adjustable in angular position by means of a worm (9) and a worm wheel (10) arrangement to vary the phase of the camshaft rotation relative to the phase of the sprocket wheel rotation.
(FR) Assemblage pouvant faire varier la phase de rotation rotative entre une roue dentée d'entraînement (6) et un arbre à cames (1), comprenant un support (8) fixé à la roue dentée et comportant des engrenages coniques intermédiaires (B, E et C, D). Les engrenages coniques intermédiaires (E, D) sont en prise avec un engrenage conique (f) fixé sur l'arbre à cames (1) pour lui transmettre un mouvement de rotation. Les engrenages coniques externes (B, C) sont en prise avec un engrenage annulaire (F) porté par un arbre à douille (2) dont la position angulaire peut être ajustée à l'aide d'une vis sans fin (9) et d'une roue hélicoïdale (10) de manière à faire varier la phase de rotation de l'arbre à cames par rapport à la phase de rotation de la roue dentée.
