Abstract

L'invention concerne une chaîne de transmission et un engrenage formant un ensemble monobloc utilisé dans un système de transmission mécanique caractérisé en ce que les galets, le pignon silencieux, la courroie à créneaux synchronisée et la transmission sont regroupés dans un seul et même système monobloc de transmission par glissement. Une pièce de l'armature de la chaîne de transmission se compose d'au moins une chaîne dentée ou d'une chaîne de couplage qui se déboîtent après superposition de couches. A différents emplacements des parties supérieures des chaînes de transmission et des chaînes de couplage sont usinées des configurations triangulaires, courbées, elliptiques, ovales, rectangulaires et autres ainsi que des configurations linéaires, arquées et autres qui tracent des formes selon les besoins, à savoir un T ou des formes à angles différents. Quant aux parties inférieures à droite et à gauche des chaînes dentées, elles adoptent notamment des formes arrondies, elliptiques, ovales, rectangulaires ou triangulaires dont le centre présente un orifice pour pivot tandis que les formes usinées sur la partie centrale des chaînes dentées sont notamment triangulaires, arrondies, elliptiques, ovales, rectangulaires, rectilignes ou arquées et conforment l'intérieur selon les besoins. Ainsi, la forme des dents intérieures épouse celle des dents de l'engrenage meneur comprenant une base, une pointe et une partie centrale.
