Patent

CA 2482988

A gear and method for producing the gear. The gear has a gear tooth profile conjugate to a gear basic-cutter tooth-profile having an addendum with a convex portion having an addendum point proximal to a pitch line and a dedendum with a concave portion having a dedendum point proximal to the pitch line. The convex portion is complementary with a corresponding portion of a mating-gear basic-cutter tooth-profile dedendum. The concave portion is complementary with a corresponding portion of the mating-gear basic-cutter tooth-profile addendum. A transition zone between the addendum point and the dedendum point has a predetermined width. The gear basic-cutter tooth-profile has a predetermined half pitch relief at the pitch line and continuity of profile and continuity of slope at the addendum point.

L'invention concerne un pignon et un procédé permettant de fabriquer ledit pignon. Ce pignon présente un profil de dent correspondant à un profil de dent de base de fraise comprenant une saillie dotée d'une partie convexe à point de saillie proximal à un module primitif, et un creux doté d'une partie concave à point de creux proximal audit module primitif. La partie convexe est complémentaire d'une partie correspondante d'un creux de profil de dent de base de fraise correspondant. La partie concave est complémentaire d'une partie correspondante de la saillie de profil de base de fraise correspondant. Une zone de transition entre le point de saillie et le point de creux présente une largeur prédéterminée. Le profil de dent de base de fraise présente une dépouille de demi-pas prédéterminée au niveau du module primitif, une continuité de profil et une continuité de pente au niveau du point de saillie.
