Abstract

Système d'essai de résistance de denture de pignons, comprenant un bâti (15), un dispositif d'immobilisation du pignon (11) à tester pourvu d'un support central cylindrique (28) qui est solidaire du bâti et sur lequel peut être monté coaxialement le pignon, un dispositif d'indexation angulaire (22) dudit pignon relativement au support et un poinçon (24) de sollicitation pour exercer sur une dent de la denture une contrainte de test de résistance mécanique de la dent. La direction d'application de la contrainte par le poinçon sur la dent est inclinée par rapport à un rayon du support central (28). Procédé d'essai de résistance mécanique de denture de pignons comportant le positionnement d'un pignon (11) contre le poinçon (24) et l'application sensiblement statique de la contrainte sur la dent, suivant la direction inclinée. La contrainte sur un flanc de la dent est sensiblement perpendiculairement à une tangente de ce flanc.Pinion tooth strength test system, comprising a frame (15), a device for immobilizing the pinion (11) to be tested provided with a cylindrical central support (28) which is integral with the frame and on which can be coaxially mounted on the pinion, an angular indexing device (22) of said pinion relative to the support and a biasing punch (24) for exerting on a tooth of the toothing a mechanical strength test stress of the tooth. The direction of application of the stress by the punch on the tooth is inclined relative to a radius of the central support (28). A method of testing the mechanical strength of pinion toothing comprising positioning a pinion (11) against the punch (24) and applying the stress substantially static to the tooth, in the inclined direction. The stress on a flank of the tooth is substantially perpendicular to a tangent to this flank.
