Description

Zahnradschabemaschine, bei der ein zu schabendes Werkstückrad mit einem mit Schneiden versehenen Werkzeugrad abgerollt wird Vorliegende Erfindung betrifft eine Maschine zum Schaben der Zahnflanken von Stirnrädern, bei der ein mit Schneiden versehenes Werkzeugrad mit dein zu schabenden Werkstückrad abgerollt wird, während gleichzeitig ,eine Hinundherbewegung des Werkstückrades in axialer Richtung erfolgt, um die ganze Breite desselben gleichzeitig zu schaben.Gear shaving machine in which a workpiece wheel to be scraped is also included a tool wheel provided with cutting edges is unrolled The present invention relates to a machine for scraping the tooth flanks of spur gears, in which a Tool wheel with cutting edges unrolled with your workpiece wheel to be scraped is, while at the same time, a reciprocating movement of the workpiece wheel in the axial direction Direction is made to scrape the entire width of the same at the same time.

Um den Zahnflanken eine erwünschte ballige Form zu geben, muß der erwähnten axialen Hinundherbewegugg eine zusätzliche geringe Schwenkbewegung des Werkstückrades während des Schabens hinzugefügt werden. Bei den bisher bekannten Schabemaschinen geschah dies durch Führung des das Werkstückrad tragenden Trägers in einer verstellbaren schrägen Führung. Diese Bauart hat aber den Nachteil, daß sie bei den auftretenden starken Schabedrücken nicht starr genug ist.In order to give the tooth flanks a desired spherical shape, the mentioned axial back and forth movement an additional slight pivoting movement of the Workpiece wheel can be added during scraping. With the previously known Scraping machines did this by guiding the carrier carrying the workpiece wheel in an adjustable inclined guide. This type of construction has the disadvantage that it is not rigid enough with the strong scraping pressures that occur.

Gemäß der vorliegenden Erfindung wird dieser Nachteil dadurch beseitigt, daß der das Werkstückrad aufnehmende Träger kippbar auf dem Maschinenrahmen abgestützt ist, durch zwei in verhältnismäßig großem Abstand voneinander befindliche Führungsleisten an dem Maschinenrahmen gehalten wird und daß der Schabdruck in seiner Kraftrichtung durch eine Rolle aufgenommen wird, die den Träger unmittelbar in Richtung des Schabdruckes an einer Schiene am Maschinenrahmen abstützt. Die Hinundherbewegung des Trägers in Richtung der Werkstückradachse erfolgt erfindungsgemäß durch zwei gleichförmig angetriebene Kurbeltriebe, deren Radien verschieden lang einstellbar sind, wo,-durch die gewünschte Schwenkbewegung der Werkstückradachse während ihres Hinundherganges erzielt wird.According to the present invention, this disadvantage is eliminated by that the carrier receiving the workpiece wheel is tiltably supported on the machine frame is, by two guide strips located at a relatively large distance from each other is held on the machine frame and that the scraping pressure in its direction of force is taken up by a roller, which the carrier directly in the direction of the scraping pressure supported on a rail on the machine frame. The reciprocation of the wearer in the direction of the workpiece wheel axis takes place according to the invention by two uniformly driven crank drives, the radii of which can be set for different lengths, where, -through the desired pivoting movement of the workpiece wheel axis during its reciprocation is achieved.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. i die Seitenansicht -und Abb.2 die Vorderansicht einer erfindungsgemäßen Schabemaschine. An dem Maschinenrahmen u ist das angetriebene und mit Schneiden versehene Schaber ad bin bekannter Weise gelagert und in Eingriff stehend mit dem zu schabenden Stirnrad c, das drehbar in zwei Lagerböcken gelagert ist, die fest mit dem Träger dl. verbunden sind. Träger d wird mit seiner Rückseite c an einer entsprechenden Fläche des Maschinenrahmens a durch die beiden Führungsleisten f und f' verschiebbar gehalten. Auf seiner der Lagerung des Stirnrades c entgegengesetzten, also der unteren Seite sitzt an dem Träger ,d die in zwei Lagerböcken gelagerte Ralle" die den Träger d in Richtung des senkrecht zu der Stirnradachse erfolgenden Schabdruckes auf der Schiene h, abstützt.In the drawing, the invention is shown in an exemplary embodiment, namely Fig. i shows the side view and Fig.2 shows the front view of an inventive Scraping machine. On the machine frame u that is driven and scrapers provided with cutting edges are mounted and engaged in a known manner standing with the spur gear to be scraped c, which is rotatably mounted in two bearing blocks is fixed to the carrier dl. are connected. Carrier d is with its back c on a corresponding surface of the machine frame a through the two guide strips f and f 'kept displaceable. On its opposite to the bearing of the spur gear c, so the lower side sits on the carrier, d the stored in two bearing blocks Rail "which takes place the carrier d in the direction of perpendicular to the spur gear axis Schabdruckes on the rail h, supported.

Die Hinundherbewegung des Trägers d in Richtung parallel zur Achse des Werkstückrades b erfolgt durch die in ihrer Länge verstellbaren Kurbeln i und k über die Pleuelstangen/ und in, die an dem Träger d gelenkig angreifen.The reciprocation of the carrier d in the direction parallel to the axis of the workpiece wheel is b by the adjustable in length cranks i and k, the attack d articulated manner via the connecting rods / and, on the carrier.

Die Kurbeln i und k werden über die Schneckenwelle n durch den Motor o gleich. i mäßig angetrieben.The cranks i and k become the same via the worm shaft n through the motor o. i moderately driven.

Werden die Kurbeln i und k gleich lang eingestellt, so erfolgt die Hinundherbewegung des Trägers d parallel in Richtung der Achse des Stirnrades c. Wird Kurbel t länger als Kurbel k eingestellt, so erfolgt beim Hinundleergang eine mehr oder weniger große zusätzliche Schwenkung des Trägers d um die Achse der Rolle g, und es entsteht eine entsprechende Balligkeit der Zahnflanken des Stirnrades c. wie dies zur Erzielung eines richtigen Zahntragbildes erforderlich ist.If the cranks i and k are set to have the same length, the Reciprocation of the carrier d parallel in the direction of the axis of the spur gear c. If crank t is set longer than crank k, an is carried out with the empty gear more or less large additional pivoting of the carrier d about the axis of the roller g, and there is a corresponding crowning of the tooth flanks of the spur gear c. how this is necessary to achieve a correct tooth wear pattern.

Durch Verlängerung der Kurbel k gegenüber der Kurbel i würde eine hohle Zahnflankenform entstehen, die in der Praxis aber nicht benötigt wird.By lengthening the crank k compared to the crank i would be a Hollow tooth flank shape is created, but this is not required in practice.
