Patent
CA 2591945
The invention relates to a sintered coupling ring (1) which comprises a rim of coupling teeth (2) which is provided with wedge-shaped front surfaces (3, 4), which intersect on an axial plane, and flanks (5) which are inclined towards the base of the tooth according to an inclination angle of teeth backs (6). The flanks (5) are indented from a protruding, axis-normal shoulder (7). The aim of the invention is to provide advantageous conditions for a moulding form of the flank indentations such that the intersection planes between the wedge- shaped front surfaces (3, 4) extend to the outside of the centre of the tooth and that the shoulders (7), which are offset in an axial manner in relation to each other (7), of both of the flanks (5) of the coupling teeth (2) separate the indented flanks (5) by a flank part (8) which is essentially triangular, is parallel to the axis and which is adjacent to the front surfaces (3, 4).
L'invention concerne une bague d'accouplement (1) frittée, comportant une couronne de dents d'accouplement (2) qui présentent des faces (3,4) cunéiformes, se coupant dans un plan axial, ainsi que des flancs (5) inclinés vers le bas selon un angle d'inclinaison à partir du dos (6) de la dent en direction du pied de la dent. Les flancs (5) présentent des dépouilles à partir d'un épaulement (7) rentrant, perpendiculaire à l'axe. L'objectif de l'invention est de créer des conditions favorables pour le moulage par pression des dépouilles de flancs. A cet effet, les plans de coupe entre les faces (3,4) cunéiformes s'étendent à l'extérieur du centre de la dent et les épaulements (7), décalés axialement les uns par rapport aux autres, des deux flancs (5) des dents d'accouplement (2) séparent les flancs (5) à dépouille d'une partie de flanc (8) sensiblement triangulaire, parallèle à l'axe, adjacente aux faces (3,4).
