Description

Welle - Nabe - Verbindung Shaft - hub - connection
Die vorliegende Erfindung betrifft eine dauerhafte Welle - Nabe - Verbindung, insbesondere für Zahnräder auf einer Getriebewelle, wobei jedes Zahnrad auf der Welle mittels eines Schrumpfsitzes befestigt ist, gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a permanent shaft - hub connection, in particular for gear wheels on a gear shaft, each gear wheel being fastened on the shaft by means of a shrink fit, according to the preamble of patent claim 1.
Drehmomentübertragende Wellen mit darauf angeordneten Zahnrädern sind im Getriebebau weit verbreitet. Zur Befestigung der Zahnräder auf der Welle gibt es eine Vielzahl von Möglichkeiten. Dabei werden die Arten dieser Verbindung in elementare Welle - Nabe - Verbindungen und in kombinierte Welle - Nabe - Verbindungen unterteilt.Torque-transmitting shafts with gear wheels arranged on them are widely used in gear construction. There are a variety of options for fastening the gearwheels on the shaft. The types of this connection are divided into elementary shaft-hub connections and combined shaft-hub connections.
Zu den formschlüssigen elementaren Welle - Naben - Verbindungen gehören die Keilwellenverbindung, die Kerbzahnverbindung, die Evolventenprofilverbindung, die Poly- gonprofilverbindung, die Passfederverbindung und die Stiftverbindung .The form-fit elementary shaft-hub connections include the spline connection, the serration connection, the involute profile connection, the polygonal connection, the feather key connection and the pin connection.
Zu den kraftschlüssigen elementaren Welle - Nabe - Verbindungen gehören die Press- und Schrumpfverbindung, die Keilverbindung, die Spannringverbindung, die Spannscheibenverbindung und die Sternscheibenverbindung.The force-fit elementary shaft - hub connections include the press and shrink connection, the wedge connection, the clamping ring connection, the clamping disc connection and the star disc connection.
Zu den Stoffschlüssigen elementaren Verbindungen gehören die Schweißverbindung, die Lötverbindung und die Klebverbindung .The integral elementary connections include the welded connection, the soldered connection and the adhesive connection.
Zu den kombinierten Welle - Nabe - Verbindungen gehören als nichtstoffschlüssige kombinierte Welle - Nabe - Verbindungen die Press - Rändel - Verbindung und die PresspunktschlussVerbindung .The combined shaft - hub connections include a non-integral composite shaft - hub - Connections the press - knurled connection and the press point connection.
Zu den nichtStoffschlüssigen - Stoffschlüssigen kombi- nierten Welle - Nabe - Verbindungen gehören die Press - Kleb - Verbindung, die Press - Presslöt - Verbindung und die Press - Schweiß - Verbindung.The non-material-integral shaft-hub connections include the press-adhesive connection, the press-press-solder connection and the press-weld connection.
Schließlich gehört noch die Löt - Schweißverbindung zu den stoffschlüssigen kombinierten Welle - Nabe - Verbindungen.Finally, the soldered-welded connection is one of the integral cohesive shaft-hub connections.
All diesen bekannten Verbindungsarten ist gemeinsam, dass sie noch mit dem Nachteil behaftet sind, dass sie Be- wegungen des Zahnrades auf der Welle nicht vollständig verhindern können. Trotz optimierter Auslegungen treten zum Beispiel bei Lastspitzen sogenannte Mikro anderungen auf. Insbesondere bei Getrieben, bei denen exakte Zuordnungen der Verzahnungen verschiedener Zahnräder zueinander eine entscheidende Rolle spielen, müssen derartige Mikrowanderungen der Zahnräder auf der Welle unbedingt vermieden werden. Dies gilt insbesondere für Getriebe mit Lastverteilung auf zwei oder mehr Vorgelegewellen, da hierbei für die gesamte Lebensdauer des Getriebes eine absolute Stellungsge- nauigkeit unabdingbare Voraussetzung ist.All these known types of connection have in common that they still have the disadvantage that they cannot completely prevent movement of the gearwheel on the shaft. Despite optimized designs, so-called micro changes occur, for example, during peak loads. In particular in the case of gearboxes in which exact assignments of the toothings of different toothed wheels to one another play a decisive role, such micro-migration of the toothed wheels on the shaft must be avoided at all costs. This applies in particular to gearboxes with load distribution on two or more countershafts, since absolute positional accuracy is an essential prerequisite for the entire service life of the gearbox.
Die bei derartigen Getrieben herkömmliche Technik des Verschweißens der Zahnräder mit der Welle führt zwar zu einer relativ guten Stoffschlüssigen Verbindung, ist jedoch noch mit dem Nachteil einer nicht unerheblichen Toleranz verbunden, die zu einem gewissen Stellungsfehler führt, auf grund eines thermischen Verzuges, der durch den Schweißvorgang bedingt ist. Die erwähnte Passfederverbindung führt zu einem größeren Stellungsfehler sowie zu einer Schwächung des aus Welle und Zahnrad bestehenden Bauteils.The conventional technique of welding the gearwheels to the shaft in such gears leads to a relatively good material connection, but is still associated with the disadvantage of a not inconsiderable tolerance, which leads to a certain position error, due to a thermal distortion caused by the Welding process. The key connection mentioned leads to a larger position error and a weakening of the component consisting of shaft and gear.
Um den Nachteile des Mikrowanderns zu vermeiden, wurde bereits in der DE - A - 196 20 330 vorgeschlagen, das Zahnrad mit der Welle mittels eines Schrumpfsitzes zu verbinden und zusätzlich durch eine formschlüssige Verbindung zur Vermeidung von Bewegungen zu halten. Die formschlüssige Verbindung kann dabei eine Stiftverbindung sein, wobei der Stift entweder teilweise in die Welle eingreift oder diese vollständig durchsetzt.In order to avoid the disadvantages of micro-walking, it was already proposed in DE-A-196 20 330 to connect the gearwheel to the shaft by means of a shrink fit and additionally to hold it by means of a positive connection to avoid movements. The positive connection can be a pin connection, the pin either partially engaging the shaft or completely penetrating it.
Eine Verbindung eines Zahnrades mit einer sich drehenden Welle zur Drehmomentübertragung mittels eines Schrumpf- sitzes ohne zusätzliches formschlüssiges Bauteil, sei es eine Passfeder, eine Mitnahmeverzahnung oder eine Verstif- tung ( auch Schrumpfpressverband genannt ) wird nicht nur in Getrieben für Kraftfahrzeuge eingesetzt, sondern ganz allgemein in einer Vielzahl von Maschinen.A connection of a gearwheel with a rotating shaft for torque transmission by means of a shrink fit without an additional form-fitting component, be it a feather key, driving teeth or a pin (also called shrink fit) is used not only in gearboxes for motor vehicles, but in general in a variety of machines.
So beschreibt zum Beispiel die DE - A - 198 50 383 einen hydrodynamischen Retarder, der einem Getriebe in einem Kraftfahrzeug nachgeordnet ist und der einen in einem Re- tardergehäuse angeordneten Rotor aufweist sowie einen im Retardergehäuse angeordneten Stator, der sich über eineFor example, DE-A-198 50 383 describes a hydrodynamic retarder, which is arranged downstream of a transmission in a motor vehicle and which has a rotor arranged in a retarder housing, and a stator arranged in the retarder housing, which is arranged over a
Feststelleinrichtung auf dem Gehäuse abstützt. Am Gehäuse ist eine Messeinrichtung für das Retarderbremsmoment vorgesehen, die von der Feststelleinrichtung beaufschlagt wird, wobei die Messeinrichtung mit einer Steuereinrichtung ver- bunden ist.Locking device is supported on the housing. A measuring device for the retarder braking torque is provided on the housing, which is acted upon by the locking device, the measuring device being connected to a control device.
Die Messeinrichtung am Retardergehäuse kann hierbei als Reaktionsnocken ausgeführt sein, der die Messeinrich- tung direkt beaufschlagt oder aber ein Statorvorsprung im Gehäuse, der mittels eines Schrumpfsitzes befestigt ist.The measuring device on the retarder housing can be designed as a reaction cam that device directly applied or a stator projection in the housing, which is attached by means of a shrink fit.
Schließlich beschreibt die DE - A - 101 34 245 ein Ge- triebe mit einer inneren Leistungsaufteilung, das aus einem mit einer Eingangswelle bzw. mit einer Ausgangswelle verbundenen Großzahnrad besteht, welches von einer Vielzahl von Ritzeln umgeben ist, deren Zahnritzel mit ihm kämmen und das sowohl als Übersetzungs- wie auch als Unterset- zungsgetriebe verwendet werden kann. Zur Übertragung der Drehmomente der Rotorwelle in einer Getriebehohlwelle ist eine SchrumpfScheibe vorgesehen. Das Getriebe eignet sich insbesondere zum Antrieb von Generatoren durch die Rotoren von Windkraftanlagen.Finally, DE-A-101 34 245 describes a transmission with an internal power distribution, which consists of a large gear wheel connected to an input shaft or to an output shaft, which is surrounded by a large number of pinions, the pinions of which mesh with it and that can be used both as a transmission and a reduction gear. A shrink disk is provided to transmit the torques of the rotor shaft in a hollow gear shaft. The gearbox is particularly suitable for driving generators through the rotors of wind turbines.
Aufgabe der vorliegenden Erfindung ist es, eine dauerhafte Welle - Nabe - Verbindung insbesondere für die Zahnräder auf einer Getriebewelle zu schaffen, mit der die Drehmomentübertragungsfähigkeit erheblich gesteigert wird.The object of the present invention is to create a permanent shaft-hub connection, in particular for the gearwheels on a transmission shaft, with which the torque transmission capability is considerably increased.
Ausgehend von einer Welle - Nabe - Verbindung der eingangs näher genannten Art erfolgt die Lösung dieser Aufgabe mit den im Anspruch 1 angegebenen Merkmalen; eine besonders vorteilhafte Ausgestaltung ist Gegenstand des Patentan- Spruchs 2.Starting from a shaft-hub connection of the type specified in the introduction, this object is achieved with the features specified in claim 1; a particularly advantageous embodiment is the subject of claim 2.
Die Erfindung sieht also vor, dass unmittelbar nebeneinander angeordnete Zahnräder auf der Welle derart ausgestaltet sind, dass sie sich teilweise überlagern und dass die sich überlagernden angrenzenden Bereiche der Zahnräder ebenfalls über einen Schrumpfsitz miteinander verbunden sind. In vorteilhafter Weise sind die sich überlagernden Bereiche der nebeneinander angeordneten Zähnräder stufenförmig ausgebildet.The invention therefore provides that gearwheels arranged directly next to one another on the shaft are designed such that they partially overlap and that the overlapping adjacent regions of the gearwheels are also connected to one another via a shrink fit. The overlapping regions of the toothed wheels arranged next to one another are advantageously designed in a step-like manner.
Aufgrund der erfindungsgemäßen Ausgestaltung kann die Drehmomentübertragungsfähigkeit der mittels des Schrumpfsitzes miteinander verbundenen Zahnräder erheblich gesteigert werden, da die zusätzliche Schrumpfsitzverbindung zwischen den Zahnrädern zu einer radialen Verstärkung der Nabe eines der Zahnräder führt und damit deren Aufweitung reduziert.Due to the configuration according to the invention, the torque transmission capacity of the gears connected to one another by means of the shrink fit can be increased considerably, since the additional shrink fit connection between the gears leads to a radial reinforcement of the hub of one of the gears and thus reduces their expansion.
Ein weiterer Vorteil der erfindungsgemäßen Ausgestaltung ist darin zu sehen, dass die Biegesteifigkeit der Wel- le insgesamt erhöht wird.Another advantage of the configuration according to the invention is that the bending stiffness of the shaft is increased overall.
Im Folgenden wird die Erfindung an Hand der Zeichnung näher erläutert, in der ein vorteilhaftes Ausführungsbei- spiel schematisch dargestellt ist.The invention is explained in more detail below with reference to the drawing, in which an advantageous exemplary embodiment is shown schematically.
Getriebe mit ihren Zahnrädern und Wellen sind dem Fachmann gut bekannt, sodass in der einzigen Figur nur die für das Verständnis der Erfindung notwendigen Bauteile dargestellt und mit Bezugszeichen versehen sind.Gear units with their gears and shafts are well known to the person skilled in the art, so that only the components necessary for understanding the invention are shown in the single figure and provided with reference numerals.
Auf der Welle 1 eines Getriebes, das insbesondere aber nicht ausschließlich ein Getriebe für ein Kraftfahrzeug ist, ist ein Zahnrad 2 mittels eines Schrumpfsitzes 3 angeordnet, d.h., fest mit ihr verbunden. Ein zweites Zahn- rad 4, das im gewählten Beispiel als Doppelzahnrad ausgeführt ist, ist unmittelbar neben dem Zahnrad 2 angeordnet und ebenfalls über einen Schrumpfsitz 5 fest mit der Welle 1 verbunden. Die Zahnräder 2 und 4 sind nun derart ausgestaltet, dass sich überlagernde Bereiche entstehen, die ebenfalls mittels eines Schrumpfsitzes 6 miteinander verbunden sind. Wie aus der Figur ersichtlich, sind in vorteilhafter Weise die sich überlagernden Bereiche stufenförmig ausgebildet.On the shaft 1 of a gearbox, which is particularly but not exclusively a gearbox for a motor vehicle, a gearwheel 2 is arranged by means of a shrink fit 3, that is, firmly connected to it. A second gear 4, which in the selected example is designed as a double gear, is arranged directly next to the gear 2 and is also fixedly connected to the shaft 1 via a shrink fit 5. The gearwheels 2 and 4 are now designed in such a way that overlapping regions arise which are also connected to one another by means of a shrink fit 6. As can be seen from the figure, the overlapping regions are advantageously stepped.
Mit dieser Erhöhung bzw. Vergrößerung der Schrumpf- sitzfläche kann die Drehmomentübertragungsfähigkeit der beiden Zahnräder 2 und 4 deutlich gesteigert werden; der zusätzlich vorgesehene Schrumpfsitz 6 verstärkt zum einen die Nabe des Zahnrades 2 in Radialrichtung und verhindert bzw. verringert dadurch deren Aufweitung, wodurch ein Teilbereich des Schrumpfsitzes 3 gestärkt wird.With this increase or increase in the shrink fit surface, the torque transmission capacity of the two gear wheels 2 and 4 can be significantly increased; the additionally provided shrink fit 6 firstly strengthens the hub of the gear 2 in the radial direction and thereby prevents or reduces its widening, as a result of which a portion of the shrink fit 3 is strengthened.
Außerdem wird eine Koppelung der beiden Zahnräder über den Schrumpfsitz 6 bewirkt, was zur Erhöhung der Drehmomentübertragungsfähigkeit beiträgt .In addition, the two gears are coupled via the shrink fit 6, which contributes to increasing the torque transmission capacity.
Ein weiterer sehr positiver Effekt ist die Erhöhung der Biegesteifigkeit der gesamten Welle.Another very positive effect is the increase in the bending stiffness of the entire shaft.
Es sei betont, dass dieses Konstruktionsprinzip auf die verschiedensten Schrumpfsitzausführungen anwendbar ist, wie zum Beispiel auf den Schrumpf lebesitz . It should be emphasized that this design principle can be applied to a wide variety of shrink fit designs, such as for example the shrink fit seat.
