Title
(EN) METHOD OF PRODUCING TOOTH FLANK SURFACE MODIFICATIONS
(FR) PROCEDE DE RECTIFICATION DE LA SURFACE DU FLANC DE DENTS DE ROUES DENTEES
Abstract
(EN)
A method of producing flank surface modifications in gear teeth by controlled removal of stock material from a work gear with a tool. The method comprises providing a gear producing machine with the tool (42) and work gear (50) being movable with respect to one another along and or about a plurality of axes. A theoretical basic machine is provided comprising a plurality of machine settings for relatively positioning and moving a tool (24) and work gear (26) with respect to one another. Each of the machine settings is defined as an active setting with each active setting being represented by a function. A desired tooth flank surface modification is determined and defined by a set of coefficients for each of the active settings. The function for each active setting is then determined based upon the respective coefficents for each active setting and the functions are transformed from the theoretical machine to the axes arrangement of the gear producing machine. By this transformation, active settings movement defined on the theoretical machine is carried out on one or more of the axes of the gear producing machine to remove stock material from the work gear (50) with the tool (42) in accordance with the active setting functions of the basic machine.
(FR)
Procédé de rectification de la surface du flanc de dents de roue dentées par enlèvement contrôlé de matière d'une roue dentée à l'aide d'un outil. Selon le procédé on utilise une machine à tailler les roues dentées dans laquelle l'outil (42) et la roue dentée (50) à rectifier sont mobiles l'un par rapport à l'autre le long et autour de plusieurs axes. La machine théorique de base comporte une série de réglages permettant de positionner et mouvoir l'outil (24) et l'engrenage (26) l'un par rapport à l'autre. Chacun des réglages de la machine est du type réglage actif, et chacun des réglages actifs est représenté par une fonction. La rectification désirée du flanc d'une dent est déterminée et définie par un ensemble de coefficients pour chacun des réglages actifs. Pour chacun des réglages actifs la fonction est alors déterminée sur la base des coefficients respectifs de chacun des réglages actifs, puis les fonctions sont transformées pour passer de la machine théorique au système d'axes de la machine de production. Du fait de cette transformation, les mouvements correspondant aux réglages actifs définis sur la machine théorique sont exécutés suivant un ou plusieurs des axes de la machine de production pour enlever de la matière de la roue dentée (50) à l'aide de l'outil (42) selon les fonction de réglage actif de la machine de base.
