The invention relates to a grooved profile for a positive fit hub-shaft connection, comprising essentially trapezium-shaped cross-sections of the toothing profile (3) as well as the hub (1) and the shaft (2). The wall thickness, at least in the region of the toothing profile, is smaller than the difference between the tip diameter and the base diameter of the toothing profile. According to the invention, at least one of the two facing flanks (4, 7, 5, 8) of the profile of the hub (1) and shaft (2) is curved, respectively arc-shaped in the cross-section. Preferably, both flanks (4,7;5,8) are arc- shaped, and the hub (1) and shaft (2) are curved in the same direction.
L'invention concerne un profil cannelé pour une liaison de forme arbre-moyeu, avec des sections pratiquement trapézoïdales des cannelures (3) ainsi que du moyeu (1) et de l'arbre (2), l'épaisseur de paroi au moins dans la zone des cannelures étant inférieure à la différence entre le diamètre de tête et le diamètre de pied de la cannelure. Selon l'invention, au moins l'un des deux flancs se faisant face (4, 7 ; 5, 8) des profils du moyeu (1) et de l'arbre (2) est bombé ou arqué au niveau de sa section. Les deux flancs (4, 7 ; 5, 8) sont de préférence arqués, les courbures du moyeu (1) et de l'arbre (2) étant réalisées dans la même direction.
