The locus of a gearing contact points called an action curve (A) is embodied in the form of a lemniscate (Lg, Ld) having a double point coinciding with the rolling point (T) of two pitch circles (Pr¿g?, Pr¿d?). The gearing contact is carried out at the top point (S¿gh?) of the lemniscate under a zero wireless pressure between two points where profiles have the same centred curve on the rolling point (T). Said invention is used for reducing wear and operating noise.
Le lieu géométrique des points de contact d'engrenage, appelé courbe d'action (A), est une lemniscate (Lg, Ld) ayant un point double coïncidant avec le point de roulement (T) des deux cercles primitifs (Prg, Prd) . La prise de contact d'engrenage a lieu en un sommet (Sgh) de la lemniscate, sous pression hertzienne nulle, entre deux points où les profils ont même courbure centrée sur le point de roulement (T). Utilisation pour réduire l'usure et le bruit de fonctionnement.
