Verfahren zum Herstellen eines rotationssymmetrischen Körpers, insbesondere eines Hohlrades für einen Planetenträger, der ein Zahnprofil und/oder Zusatzelemente aufweist, wobei für die Herstellung eines spanlose Verformung vorgesehen ist.Method for producing a rotationally symmetrical body, in particular a ring gear for a planet carrier, which has a tooth profile and / or additional elements, with provision being made for the production of a non-cutting deformation.
Hintergrund der ErfindungBackground of the Invention
Es ist allgemein bekannt, derartige rotationssymmetrische Körper, wie Hohlräder aus einem Rohling, der geschmiedet sein kann, durch Drehen und Fräsen herzustellen.It is generally known to produce such rotationally symmetrical bodies, such as ring gears, from a blank, which can be forged, by turning and milling.
Derartige rotationssymmetrische Körper sind aber aufgrund der aufwendigen Herstellung sehr teuer.Such rotationally symmetrical bodies are very expensive due to the complex production.
Es ist weiterhin bekannt, EP- 0 639 415 A2, einen rotationssymmetrischen Körper spanlos aus einer Platine durch Kaltverformung mittels Vorziehen beziehungsweise Tiefziehen und Abstrecken sowie Fließdrücken herzustellen. Wie insbesondere den Figuren 1 bis 11 zu entnehmen ist, verlangt ein derartiges Herstellungsverfahren eine Vielzahl von Herstellungsschritten, die ebenfalls noch zu kostenaufwendig sind. Des weiteren ist dieses Herstellungsverfahren nur für rotationssymmetrische Körper geeignet, die zumindest einen radial ausgerichteten Stegbereich aufweisen, von dem aus zylindrische Bereiche spanlos angeformt werden können.It is also known to produce EP-0 639 415 A2, a rotationally symmetrical body without cutting from a blank by cold forming by means of pulling or deep drawing and stretching and flow pressures. As can be seen in particular from FIGS. 1 to 11, such a production method requires a large number of production steps which are also still too expensive. Furthermore, this is Manufacturing process only suitable for rotationally symmetrical bodies which have at least one radially oriented web area, from which cylindrical areas can be molded without cutting.
Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist es daher, ein Verfahren zum Herstellen eines rotationssymmetrischen Körpers, insbesondere eines Hohlrades für einen Planetenträger zur Verfügung zu stellen, das aufbauend auf einer spanlosen Verformung die zuvor geschilderten Nachteile beseitigt und eine kostengünstige Herstellung erlaubt.The object of the invention is therefore to provide a method for producing a rotationally symmetrical body, in particular a ring gear for a planet carrier, which, based on a non-cutting deformation, eliminates the disadvantages described above and permits cost-effective production.
Zusammenfassung der ErfindungSummary of the invention
Die Aufgabe der Erfindung wird dadurch gelöst, dass in einen Blechstreifen das Zahnprofil und/oder die Zusatzelemente eingearbeitet werden, dass der Blechstreifen vor oder nach der Einarbeitung abgelängt wird, dass der Blechstreifen zu einem rotationssymmetrischen Körper gebogen wird und dass die Enden der Blechstreifen aneinander befestigt werden.The object of the invention is achieved in that the tooth profile and / or the additional elements are incorporated into a sheet metal strip, that the sheet metal strip is cut to length before or after incorporation, that the sheet metal strip is bent into a rotationally symmetrical body and that the ends of the sheet metal strips are attached to one another become.
Auf diese Weise ist es möglich, rotationssymmetrische Körper, insbesondere ringförmige Körper, wie ein Hohlrad mittels spanloser Verformung kostengünstig herzustellen.In this way, it is possible to produce rotationally symmetrical bodies, in particular ring-shaped bodies, such as a ring gear, inexpensively by means of non-cutting deformation.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche 2 bis 8.Further embodiments of the invention are the subject of dependent claims 2 to 8.
In vorteilhafter Weise erfolgt das Herstellen des Zahnprofils und/oder der Zusatzelemente spanlos durch Walzen, Prägen oder Umformen. Es handelt es sich dabei um kostengünstige Herstellungsverfahren, die auch eine hinreichende Genauigkeit liefern. In diesen Zusammenhang wird vorgeschlagen, dass das Walz-, Präge- oder Umform Werkzeug derart ausgelegt ist, dass das Zahnprofil und/oder die Zusatzelemente nach dem Biegen der Blechstreifen die gewünschte Profilform und/oder Lage der Zusatzelemente aufweisen. Je nach dem, ob das Zahnprofil später an der Innen- oder Außenwand angeordnet ist, müssen die Flanken beim Herstellen als gerader Blechstreifen mehr oder weniger geneigt sein.The tooth profile and / or the additional elements are advantageously produced without cutting by rolling, embossing or shaping. These are inexpensive manufacturing processes that also provide sufficient accuracy. In this context, it is proposed that the rolling, embossing or forming tool be designed such that the tooth profile and / or the additional elements have the desired profile shape and / or position of the additional elements after the sheet metal strips have been bent. Depending on whether the tooth profile is later arranged on the inner or outer wall, the flanks must be more or less inclined when producing them as a straight sheet metal strip.
Die Enden der Blechstreifen können durch Schweißen miteinander verbunden sein.The ends of the metal strips can be connected to one another by welding.
Es ist aber auch möglich, an den Enden der Blechstreifen zueinander passende Elemente anzuformen, wobei die Elemente während und/oder nach dem Biegevorgang ineinander eingehängt werden.However, it is also possible to form matching elements on the ends of the sheet metal strips, the elements being interlinked during and / or after the bending process.
In vorteilhafter Weise sind die Elemente als haken- und/oder T-förmige Vorsprünge an dem einen der Blechstreifen und entsprechende Ausnehmungen an dem anderen Ende (Clinch-Verbindung) ausgebildet werden. Dadurch ergibt sich eine Verbindung der Enden untereinander, die sowohl in tangentialer Richtung als auch parallel zur Mittelachse des rotationssymmetrischen Körpers eine gute stabile Verbindung der Enden gegeneinander gewährleistet. Je nach Einsatzgebiet des rotationssymmetrischen Körpers ist eine derartige Clinch- Verbindung ausreichend. Sie ist auch kostengünstig darstellbar, da sie gleichzeitig mit dem Prägen, Umformen oder Ablängen der Blechstreifen hergestellt werden kann.The elements are advantageously designed as hook-shaped and / or T-shaped projections on one of the sheet metal strips and corresponding recesses on the other end (clinch connection). This results in a connection of the ends to one another, which ensures a good stable connection of the ends to one another both in the tangential direction and parallel to the central axis of the rotationally symmetrical body. Depending on the area of application of the rotationally symmetrical body, such a clinch connection is sufficient. It can also be produced cost-effectively, since it can be produced simultaneously with the stamping, forming or cutting to length of the metal strips.
Je nach Einsatzgebiet des rotationssymmetrischen Körpers und je nach geforderter Genauigkeit können die Enden der Blechstreifen auch dann, wenn eine Clinch-Verbindung vorgesehen ist, zusätzlich miteinander verschweißt werden, beispielsweise in den Zwischenräumen der haken- und/oder T-förmigen Vorsprünge und den entsprechenden Ausnehmungen.Depending on the area of application of the rotationally symmetrical body and depending on the required accuracy, the ends of the sheet metal strips can also be welded to one another even if a clinch connection is provided, for example in the spaces between the hook-shaped and / or T-shaped projections and the corresponding recesses ,
Es können natürlich auch zwei Schweißnähte angebracht werden, wobei die eine, wie bereits beschrieben, in den Zwischenräumen angebracht wird und die andere an den Enden der haken- und/oder T-förmigen Vorsprünge und dem jeweiligen Grund der Ausnehmungen.Of course, two weld seams can also be made, the one, as already described, is made in the gaps and the others at the ends of the hook and / or T-shaped projections and the respective base of the recesses.
Bei den Zusatzelementen kann es sich um an den Blechstreifen seitlich angeformte Vorsprünge oder Ausnehmungen handeln, die im fertigen Zustand eines Hohlrades, beispielsweise parallel zur Mittelachse, ausgerichtet sind. Mit Hilfe dieser Vorsprünge beziehungsweise Ausnehmungen kann ein derartiges Hohlrad an einem weiteren Bauteil, zum Beispiel an einem Planetenträger fixiert beziehungsweise befestigt werden.The additional elements can be projections or recesses formed laterally on the sheet metal strips and aligned in the finished state of a ring gear, for example parallel to the central axis. With the aid of these projections or recesses, such a ring gear can be fixed or fastened to a further component, for example to a planet carrier.

In den Figuren 1 bis 3 ist, soweit im einzelnen dargestellt, mit 1 ein Hohlrad bei einem Planetenträger bezeichnet, das auf seiner Innenseite ein Zahnprofil 2 aufweist. Das Zahnprofil ist als Schrägverzahnung ausgebildet. Das Hohlrad weist weiterhin auf einer Seite Zusatzelemente 3 auf, die aus Vorsprüngen beziehungsweise Ausnehmungen bestehen. Mittel dieser Zusatzelemente kann das Hohlrad an einem anderen Maschinenelement, wie Planetenträger und dergleichen befestigt beziehungsweise fixiert werden. Dadurch ist eine Übertragung beliebiger Drehkräfte möglich.In Figures 1 to 3, as far as shown in detail, 1 denotes a ring gear on a planet carrier, which has a tooth profile 2 on its inside. The tooth profile is designed as helical teeth. The ring gear also has additional elements 3 on one side, which are made of projections or recesses exist. By means of these additional elements, the ring gear can be attached or fixed to another machine element, such as planet carriers and the like. This enables any torque to be transmitted.
Das Hohlrad 1 gemäß Figur 1 wird aus einem Blechstreifen 4 hergestellt. Der Blechstreifen 4 kann als Endlosmaterial vorliegen, in dem mittels Walzen, Prägen und/oder Umformen das Zahnprofil 2 und die Zusatzelemente 3 eingearbeitet werden. Die benötigte Länge des Blechstreifens 4 kann danach abgetrennt werden. Es ist aber auch möglich, vorher entsprechende Längen von Blechstreifen abzutrennen und in die beziehungsweise an diesen das Zahnprofil und die Zusatzelemente anzuformen.The ring gear 1 according to FIG. 1 is produced from a sheet metal strip 4. The sheet metal strip 4 can be in the form of an endless material in which the tooth profile 2 and the additional elements 3 are incorporated by means of rolling, stamping and / or shaping. The required length of the metal strip 4 can then be cut off. However, it is also possible to cut off corresponding lengths of sheet metal strips beforehand and to form the tooth profile and the additional elements in or on these.
Nach Biegen der entsprechend abgelängten Blechstreifen zu einer Kreisform können die Enden miteinander verschweißt werden, so dass ein formstabiles Hohlrad entsteht. After bending the correspondingly cut sheet metal strips into a circular shape, the ends can be welded together so that a dimensionally stable ring gear is created.
