摘要:
A method for machining straight toothed conical gear wheels (1). At least one part of the tooth profiles are milled with a milling cutter (2), the left tooth profiles are milled at a different moment from the right tooth profiles, the machined conical gear wheel (1) is rotated at an angle between the milling of one left tooth profile and the milling of a right tooth profile, and the inclination of the milling cutter axis remains unchanged during the milling of said gear wheel. The angle of rotation is not a multiple of the base pitch α .
摘要:
Un agencement d'usinage augmente les possibilités d'utilisation de dispositifs qui exécutent des phases d'usinage semblables et placées sur des courbes prédéterminées (5) (comme lors de la taille d'engrenages) dans le sens d'un diamètre d'usinage (14) accru alors que les dimensions principales de la machine restent les mêmes. A cet effet, les pièces à usiner (1) dont le plus grand diamètre d'usinage (14) n'est plus susceptible d'être concentriquement tendu par rapport au centre de réception (2) de la pièce à usiner (mécanisme diviseur) sont excentriquement disposées par rapport au centre (2). En outre, l'outil (7) est dirigé vers des positions de travail (6) situées à chaque fois sur des coordonnées (y, z) différentes par au moins trois éléments moteurs linéaires (10, 12, 17) coopératifs, agencés en croix et dirigés simultanément par un ordinateur programmé) conformément à la courbe prescrite (5). Il devient donc possible de procéder à l'usinage de pièce à usiner en forme de segments ou de barres (7), outre des roues, dans les limites du diamètre d'usinage et conformément aux courbes prescrites (5). En période de baisse de commande de grosse pièces, la même machine peut être rationnellement utilisée pour usiner des pièces en série plus petites (roues).
摘要:
The invention relates to a device for generating teeth of workpieces (3) by hob peeling, having a workpiece spindle (1) that can be rotatably driven for accommodating the work wheel (3) to be geared, particularly internally, and having a tool spindle (2) that can be rotatably driven, said tool spindle (2) carrying a peeling wheel (4), which has a regular tooth pitch determined by the tooth spacing of the gearing of the workpiece (3). In order to improve the performance of the generic device and/or generic method, and to provide the peeling wheel suited therefor, it is proposed that the distance between at least some of the teeth of the peeling wheel (4) that are of identical shape corresponds to a multiple of the regular tooth pitch.
摘要:
Rotary cutting blades (20) for cutting and forming rack teeth (2) in a rack forming surface (16) of a tubular body (11) are disposed in parallel with each other along a longitudinal direction of the tubular body (11). A direction parallel with the rotary cutting blades (20) and the longitudinal direction of the tubular body (11) are maintained in parallel with each other. A number of rack teeth (2) are cut and formed simultaneously in the rack forming surface (16) of the tubular body (11) by means of the respective rotary cutting blades (20). At this time, central positions of root portions (2a) of the rack teeth formed in the rack forming surface (16) of the tubular body (11) are cut by means of a rotart cutting blade (22) at the same time when the rack teeth (2) are cut and formed. The phases of the rack teeth (2) of the tubular body (11) which is divided into two positively coincide with each other even in such a divided state to thereby maintain the strength of the rack teeth (2), thus eliminating a risk of the teeth being broken.
