Abstract

L'invention concerne une denture, notamment située entre un pignon de démarrage (22) et une couronne dentée (25) d'un moteur à combustion interne. La denture est conçue comme une denture droite ou une denture hélicoïdale et comprend un certain nombre de dents (202) s'engrenant mutuellement. Les épaisseurs des différentes dents (212) sont asymétriques : elles sont notamment conçues avec une réduction ou un élargissement d'un ou des deux côtés.
