Title (EN) APPARATUS AND SYSTEM FOR LIGHT-WEIGHT, FLEXIBLE DOUBLE-HELICAL GEAR
(FR) APPAREIL ET SYSTÈME POUR ENGRENAGE HÉLICOÏDAL DOUBLE FLEXIBLE ET LÉGER
Abstract:
(EN) A gear includes a first gear rim, a second gear rim, and an axial groove. The first gear rim has a first gear rim rotational stiffness and includes a plurality of first gear teeth. The second gear rim has a second gear rim rotational stiffness. The second gear rim includes a plurality of second gear teeth complementing the plurality of first gear teeth defining a plurality of complementary first gear teeth and a plurality of complementary second gear teeth. The axial groove extends between the first gear rim and the second gear rim. The axial groove has an axial groove rotational stiffness that less than at least one of the first gear rim rotational stiffness and the second gear rim rotational stiffness.
(FR) La présente invention concerne un engrenage comprenant un premier rebord d'engrenage, un second rebord d'engrenage et une rainure axiale. Le premier rebord d'engrenage présente une première rigidité rotative de rebord d'engrenage et comprend une pluralité de premières dents d'engrenage. Le second rebord d'engrenage présente une seconde rigidité rotative de rebord d'engrenage. Le second rebord d'engrenage comprend une pluralité de secondes dents d'engrenage complémentaires de la pluralité de premières dents d'engrenage définissant une pluralité de premières dents d'engrenage complémentaires et une pluralité de secondes dents d'engrenage complémentaires. La rainure axiale s'étend entre le premier rebord d'engrenage et le second rebord d'engrenage. La rainure axiale a une rigidité rotative de rainure axiale qui est inférieure à la première rigidité rotative de rebord d'engrenage et/ou à la seconde rigidité rotative de rebord d'engrenage.
