Description

für beide Flankenfor both flanks
Es ist bekannt, zum Abrichten der Schleifscheiben bei Zahnräderschleifmaschinen für Evolventenverzalinungen dem Abrichtwerkzeug eine Bewegung zu erteilen, die dem Abrollen einer Geraden auf einem Kreis entspricht, wobei eine Antriebsvorrichtung für das Abrichtwerkzeug verwendet wird, die auf dem bekannten Prinzip der Evolventenkonstruktion aufgebaut ist. Das Profil der Zähne setzt sich aus zwei Teilen zusammen, da nur der obere Teil eine Evolvente ist, wähnend der zweite sich unmittelbar an den ersten anschließende und den Übergang zum Zahnrad unterhalb des Grundkreises bildende Teil geradlinig ist.It is known to dress the grinding wheels in gear grinding machines for Involute serrations give the dressing tool a movement that encourages unrolling corresponds to a straight line on a circle, with a drive device for The dressing tool used is based on the known principle of the involute design is constructed. The profile of the teeth is made up of two parts, since only the upper part is an involute the second immediately adjoins the first and the transition to the gear below the base circle forming part is straight.
Besonders bei Rädern mit kleinen Zähnezahlen ist die Abweichung der beiden Übergangsteile einer Zahnlücke von der Parallelität sehr bedeutend, da das Übergangsprofil jeder Zahnflanke für sich stets senkrecht zur Schleifspindel stehen muß, um es durch eine Bewegung senkrecht zur Schleifspindel erzeugen zu können. Weil es also unmöglich ist, mit einer einzigen Bewegung senkrecht zur Schleifspindel beide Übergangsprofile" gleichzeitig herzustellen, können auch nicht beide Profile auf einer einzigen Schleifscheibe vorhanden sein. Nach der Erfindung werden deshalb zum Schleifen der rechten und linken Flanke der Zähne je eine Schleifscheibe angeordnet. Dann kann man gegenüber den bekannten Maschinen eine wesentliche Erleichterung der Fabrikation, dadurch erzielen, daß zum Abrichten der Schleifscheiben zwei an dem gleichen und zwischen den beiden Scheiben angeordneten Halter befestigte Abrichtwerkzeuge dienen, deren Abstand unmittelbar einstellbar ist. Man kann mithin durch Einstellen des Abstandes, z. B. unter Verwendung .einer Mikrometerschraube, jeweils die Zahnstärke bestimmen, was früher nur durch Ausprobieren möglich war.The difference between the two transition parts is particularly evident on wheels with a small number of teeth a tooth gap of the parallelism is very important, since the transition profile of each tooth flank is always perpendicular to the Grinding spindle must stand in order to generate it by a movement perpendicular to the grinding spindle to be able to. Because it is impossible, with a single movement perpendicular to the grinding spindle, both transition profiles " It is also not possible to produce both profiles on a single grinding wheel at the same time to be available. According to the invention are therefore used to grind the right and left On each side of the teeth a grinding wheel is arranged. Then you can face the known machines a substantial facilitation of the fabrication, thereby achieve, that for dressing the grinding wheels two on the same and between the two Disks arranged holder attached dressing tools are used, the distance between them directly is adjustable. You can therefore by adjusting the distance, for. B. using .ein micrometer screw, respectively determine the tooth thickness, which was previously only possible by trial and error.
Zweckmäßig erfolgt dabei die Bewegung zur Erzeugung des Evolventenprofils in einer Ebene parallel oder annähernd parallel zur Achse der Schleifspindel, während der Übergangsteil bei stillstehendem Abrichtwerkzeug durch Bewegung der Schleifscheibe oder bei ortsfester Schleifscheibe durch Bewegen des Abrichtwerkzeuges in einer zur Schleifspindel senkrecht oder annähernd senkrecht Hegenden Ebene abgezogen wird.The movement for generating the involute profile expediently takes place in one Plane parallel or approximately parallel to the axis of the grinding spindle, while the transition part with a stationary dressing tool by moving the grinding wheel or with stationary grinding wheel by moving the dressing tool in one to the grinding spindle is deducted vertically or approximately vertically Hegenden level.
Auf der Zeichnung ist schematisch ein Ausführungsbeispiel der Erfindung gegeben.An exemplary embodiment of the invention is shown schematically in the drawing.
