Description

Beim Schleifen von Verzahnungen ist es erforderlich, daß die Form der Schleifscheibe genau der Zahnflankenform des Werkstückes entspricht. Dies wird in bekannter Weise durch Abziehvorrichtungen erreicht, bei denen mittels eines durch Kurven geführten oder in einer evolventischen Abwälzung mitgelenkten Diamanten die entsprechende Zähnflankenform in die Schleifscheibe eingezogen wird.When grinding gears, it is necessary that the shape the grinding wheel corresponds exactly to the tooth flank shape of the workpiece. this will achieved in a known manner by pullers, in which by means of a Curved diamonds or diamonds steered in an involute shift corresponding tooth flank shape is drawn into the grinding wheel.

Wird bei solchen Vorrichtungen eine Verstellung des Diamanten nötig, dann ist eine langwierige Einjustierung der Schleifmaschine nötig bis die evolventische Bewegung des Diamanten wieder genau der Lage der Zahnflankenform zum Werkstückmittelpunkt entspricht.If it is necessary to adjust the diamond with such devices, then a lengthy adjustment of the grinding machine is necessary until the involute Movement of the diamond again exactly the position of the tooth flank shape to the workpiece center is equivalent to.

Diesen Nachteil behebt die Erfindung, mittels einer für eine bestimmte Zahnform. hergestellten Einröllwalze, welche auf einem Vorrichtungskörper schwenkbar angeordnet ist, wobei die Lage der Einrollwalze mit der Lage des zu schleifenden Zahnflankenprofils übereinstimmt.The invention overcomes this disadvantage by means of a for a specific Tooth shape. produced rolling roller, which is pivotable on a device body is arranged, the position of the curling roller with the position of the to be ground Tooth flank profile matches.

Inder Zeichnung ist die Erfindung in einem Ausführungsbeispiel -dargestellt; und zwar zeigt Abb. i die Seitenansicht und Abb. 2 die Vorderansicht der erfindungsgemäßen Abrichtvorrichtung.In the drawing, the invention is shown in an exemplary embodiment; namely Fig. 1 shows the side view and Fig. 2 shows the front view of the invention Dressing device.

In dem uni die Achse a schwenkbar gelagerten Vörrichtungskörper b ist die Welle c drehbar gelagert und mit derselben .die Einrollwalze d verbunden. Der Antrieb hierfür erfolgt über -die Antriebsscheibe e. Mittels der Schraube f kann die Einrollwalze gegen die Schleifscheibe g in einfacher Weise nachgestellt werden, wobei sich die Einrollwalze d um das Achsmittel a genau im Wälzkreis h des Zahnrades i bewegt. Beim Schleifvorgang ist das Zahnrad i auf gleicher Achse a gelagert.In the device body b, which is pivotably mounted on the axis a, the shaft c is rotatably mounted and connected to the same .die roll-in roller d. The drive for this takes place via the drive pulley e. By means of the screw f, the rolling-in roller can be readjusted in a simple manner against the grinding wheel g, the rolling-in roller d moving about the axis means a precisely in the pitch circle h of the gear wheel i. During the grinding process, the gear wheel i is mounted on the same axis a.
