Description
Die Erfindung betrifft eine Rotorwelle für ein elektrisches Aggregat, mit einem Rohrteil und mit mindestens einem Flanschteil, insbesondere mit einem ersten und einem zweiten Flanschteil, wobei das Flanschteil mit dem Rohrteil drehfest über eine Fügeverbindung verbunden ist.The invention relates to a rotor shaft for an electrical unit, with a pipe part and at least one flange, in particular with a first and a second flange, wherein the flange is rotatably connected to the pipe part via a joint connection.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer Rotorwelle für ein elektrisches Aggregat, mit den Schritten: Bereitstellen eines Rohrteiles und mindestens eines Flanschteiles, Fügen des Flanschteiles und des Rohrteiles.The invention further relates to a method for producing a rotor shaft for an electrical unit, comprising the steps of: providing a tube part and at least one flange part, joining the flange part and the tube part.
In elektrischen Aggregaten, insbesondere elektrischen Maschinen von Hybridantrieben von Kraftfahrzeugen, werden hohle Rotorwellen eingesetzt. Im Inneren der Rotorwelle ist Bauraum für weitere Komponenten der elektrischen Aggregate oder für Komponenten angrenzender Bauteile des Hybridantriebs geschaffen. Das Rohrteil kann auf einer zylindrischen äußeren Umfangsfläche Lamellen- und Rotorblechpakete tragen. Ferner sind dort Rotorwicklungen oder Permanentmagnete angeordnet, die in Aufnahmenuten des Lamellen- oder Rotorblechpaketes untergebracht sein können. Die Rotorwelle weist ein Rohrteil und zwei Flanschteile auf, wobei jedes der Flanschteile an einem der beiden offenen Enden des Rohrteiles angeordnet ist. Die Flanschteile sind mit dem Rohrteil verbunden.In electrical units, in particular electric machines of hybrid drives of motor vehicles, hollow rotor shafts are used. In the interior of the rotor shaft space is created for other components of the electrical units or components of adjacent components of the hybrid drive. The tube part can carry lamella and rotor lamination packages on a cylindrical outer peripheral surface. Furthermore, rotor windings or permanent magnets are arranged there, which can be accommodated in receiving grooves of the lamella or rotor lamination stack. The rotor shaft has a tube part and two flange parts, wherein each of the flange parts is arranged at one of the two open ends of the tube part. The flange parts are connected to the pipe part.

Die im Stand der Technik bekannten Rotorwellen sind noch nicht optimal ausgebildet. Die im Stand der Technik bekannten Rotorwellen sind aufwendig zu montieren. Die Verbindungen der Flanschteile mit dem Rohrteil sind unterschiedlichen Kräften ausgesetzt. Zum einen müssen die Verbindungen im Betrieb auftretenden Drehmomenten standhalten und zum anderen können Biegeumlaufbelastungen der Rotorwelle auftreten, so dass die Verbindungen zwischen den Flanschteilen und dem Rohrteil ebenfalls Axialkräften ausgesetzt sind.The known in the art rotor shafts are not yet optimally formed. The known in the art rotor shafts are expensive to assemble. The connections of the flange parts with the pipe part are subjected to different forces. On the one hand, the connections must withstand torques occurring during operation and, on the other hand, bending circulating loads of the rotor shaft can occur so that the connections between the flange parts and the tubular part are also exposed to axial forces.
Der Erfindung liegt daher die Aufgabe zu Grunde, die eingangs genannte Rotorwelle und das eingangs genannte Verfahren derart auszugestalten und weiterzubilden, so dass eine aufwändige Montage der Rotorwelle vermieden ist und eine hinreichende axiale Belastbarkeit der Rotorwelle erreicht ist.The invention is therefore based on the object, the above-mentioned rotor shaft and the aforementioned method in such a way and further, so that a complex assembly of the rotor shaft is avoided and a sufficient axial load capacity of the rotor shaft is reached.
Diese der Erfindung zugrunde liegende Aufgabe wird nun dadurch gelöst, dass das Rohrteil und das Flanschteil durch eine Schnappverbindung gegen axiales Verschieben gesichert sind. Diese der Erfindung zugrunde liegende Aufgabe wird nun für das Verfahren dadurch gelöst, dass das Rohrteil oder das Flanschteil mit einer Nut versehen wird, wobei das Flanschteil oder das Rohrteil mit einem passenden Eingriffsbereich versehen wird, wobei der Eingriffsbereich und die Nut zur Ausbildung einer Schnappverbindung zwischen dem Rohrteil und dem Flanschteil ausgestaltet sind. Insbesondere wird in das Rohrteil an beiden Enden innen eine Nut eingearbeitet. Durch Drehen kann die Nut in das Rohrteil eingearbeitet werden. An den beiden Flanschteilen wird durch eine drehende Bearbeitung ein entsprechendes Gegenstück zur Nut erzeugt. Dieses Gegenstück bildet einen Eingriffsbereich. Beim Fügen der Teile schnappen die Eingriffsbereiche in die entsprechenden Nuten und verhindern somit ein axiales Herausrutschen der beiden Flanschteile aus dem Rohrteil. Wenn die entsprechenden Blechpakete auf der Rotorwelle montiert worden sind, ist diese Schnappverbindung zusätzlich gegen axiales Herausrutschen gesichert. Durch das Fügen sind das jeweilige Flanschteil und das Rohrteil ferner drehfest miteinander verbunden. Das Rohrteil und/oder die Flanschteile weisen jeweils Wirkflächen auf. Diese Wirkflächen werden vordem Fügen des jeweiligen Flanschteils mit dem Rohrteil bearbeitet. Insbesondere sind die Wirkflächen gerändelt. Die Wirkflächen weisen eine Rändelung auf. Die Wirkflächen weisen insbesondere eine axiale Rändelung auf. Die Wirkflächen wirken beim Fügen zusammen. Die Flanschteile werden beim Fügen in das Rohrteil eingepresst. Hierdurch kann eine kombinierte kraft- und formschlüssige Verbindung entstehen. Durch die Längsrändelung ist diese Fügeverbindung insbesondere hoch drehmomentbelastbar. Um auch diese Belastung gut aufnehmen zu können und zu verhindern, dass das Flanschteil aus dem Rohrteil herausgedrückt wird, ist diese Fügeverbindung zusätzlich durch die Schnappverbindung axial gesichert. Die eingangs genannten Nachteile sind daher vermieden und entsprechende Vorteile sind erzielt.This object of the invention is now achieved in that the pipe part and the flange are secured by a snap connection against axial displacement. This object of the invention is based on the method that the tube part or the flange part is provided with a groove, wherein the flange part or the tube part is provided with a mating engagement region, wherein the engagement region and the groove for forming a snap connection between the pipe part and the flange part are designed. In particular, a groove is incorporated in the tube part at both ends inside. By turning the groove can be incorporated into the pipe part. At the two flange parts, a corresponding counterpart to the groove is produced by a rotating machining. This counterpart forms an engagement area. When joining the parts snap the engaging portions in the corresponding grooves and thus prevent axial slipping out of the two flange parts of the pipe part. If the corresponding laminated cores have been mounted on the rotor shaft, this snap connection is additionally secured against axial slipping out. By joining the respective flange and the pipe part are also rotatably connected to each other. The pipe part and / or the flange parts each have active surfaces. These active surfaces are processed before joining the respective flange with the pipe part. In particular, the active surfaces are knurled. The active surfaces have a knurling. The active surfaces have, in particular, an axial knurling. The active surfaces act together during joining. The flange parts are pressed into the pipe part during joining. As a result, a combined non-positive and positive connection arise. Due to the Längsrändelung this joint connection is particularly high torque. In order to accommodate this load well and to prevent the flange is pushed out of the pipe part, this joint connection is additionally secured axially by the snap connection. The aforementioned disadvantages are therefore avoided and corresponding advantages are achieved.
Es gibt nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße Rotorwelle in vorteilhafter Art und Weise auszugestalten und weiterzubilden. Hierfür darf zunächst auf die dem Patentanspruch 1 nachgeordneten Patentansprüche verwiesen werden.
