Zahnradgear
Die Erfindung betrifft ein Zahnrad, bestehend aus einem äußeren Zahnkranz, einer Nabe und einer den Zahnkranz und die Nabe einstückig verbindenden profilierten Stegzone, die in unterschiedlichen Ebenen am Zahnkranz und an der Nabe angebunden ist.The invention relates to a gear wheel consisting of an outer gear ring, a hub and a profiled web zone integrally connecting the gear ring and the hub, which is connected to the gear ring and the hub at different levels.
Rohlinge für derartige Zahnräder sind aus der DE-PS 908 317 bekannt. Es handelt sich dabei um einstückige im Preß- oder Schmiedeverfahren herstellbare Getrieberäder, bei denen der äußere Zahnkranz und die Nabe durch eine vollständig geschlossene, scheibenförmige Stegzone verbunden ist. Diese scheibenartige Stegzone besteht vorzugsweise aus wechselseitig gewölbten Kreissektoren, die aufgrund dieser Form in unterschiedlichen Ebenen am Zahnkranz bzw. an der Nabe angebunden sind. Bei diesen Zahnrädern wird die scheibenartige Stegzone gefordert, um Festigkeitsanforderungen zu gewährleisten und Schwingungserscheinungen, die zur Geräuschbildung führen können, zu vermeiden. Diese scheibenförmige Stegzone erfordert einen relativ hohen Materialaufwand zu erkennen.Blanks for such gears are known from DE-PS 908 317. These are one-piece gears that can be produced using a pressing or forging process, in which the outer gear ring and the hub are connected by a completely closed, disk-shaped web zone. This disk-shaped web zone preferably consists of alternating curved circular sectors that, due to this shape, are connected to the gear ring or the hub at different levels. The disk-shaped web zone is required for these gears in order to ensure strength requirements and to avoid vibration phenomena that can lead to noise. This disk-shaped web zone requires a relatively high material expenditure to be recognized.
Bekannt sind ebenfalls aus der US-PS 3 371 549 Zahnräder mit speichenartig ausgebildeten Stegzonen, bei denen die speichenartigen Elemente stets mittig sowohl an der Innenseite des Zahnkranzes als auch an der Nabe angebunden sind. Diese speichenartigen Stegzonen könnenAlso known from US-PS 3 371 549 are gear wheels with spoke-like web zones, in which the spoke-like elements are always connected centrally to both the inside of the gear rim and the hub. These spoke-like web zones can

dabei auch profiliert ausgebildet sein. Im Schmiede- oder Preßverfahren hergestellte Zahnräder dieser Art werden als Rohlinge mit Wärmebehandlungen vergütet. Dabei zeigen sich erhebliche Verzugserscheinungen zwischen Zahnkranz und Nabe, die auf die speziellen Ausbildungen der Stegzonen zurückzuführen sind.can also be profiled. Gears of this type, manufactured using forging or pressing processes, are tempered as blanks using heat treatments. This results in significant distortions between the gear rim and the hub, which are due to the special design of the web zones.
Die Aufgabe der Erfindung besteht darin, den Stegzonenbereich eines Zahnrades, welches im Preß- oder Schmiedeverfahren herstellbar sein soll, hinsichtlich seines Verzugsverhaltens bei Wärmevergütungsverfahren &iacgr;&ogr; und im Hinblick auf geforderte Gewichtsreduzierungen zu optimieren.The object of the invention is to optimize the web zone area of a gear, which is to be manufactured by pressing or forging, with regard to its distortion behavior during heat treatment processes &iacgr;&ogr; and with regard to required weight reductions.
Gelöst wird die Aufgabe mit einem Zahnrad mit den Merkmalen des Anspruchs 1. Infolge der Anordnung der speichenartigen Stege werden Verzugserscheinungen bei Wärmebehandlungen entsprechender Zahnradrohlinge weitgehend vermieden. Die Ausbildung der Stegzone in Form von einzelnen Speichen führt zu erheblichen Materialreduzierungen bei ausreichenden Festigkeiten.The problem is solved with a gear with the features of claim 1. Due to the arrangement of the spoke-like webs, distortion phenomena during heat treatment of corresponding gear blanks are largely avoided. The formation of the web zone in the form of individual spokes leads to considerable material reductions while maintaining sufficient strength.
Eine bevorzugte Ausführungsart eines Zahnrades wird mit den Merkmalen des Anspruchs 2 angegeben. Solche Zahnräder lassen sich besonders gut verformen und weisen gute Festigkeitseigenschaften und Schwingungsdämpfungseigenschaften auf, insbesondere, wenn sie gemäß Anspruch 3 ausgebildet sind.A preferred embodiment of a gear wheel is specified with the features of claim 2. Such gear wheels can be deformed particularly well and have good strength properties and vibration damping properties, in particular when they are designed according to claim 3.
Es erweist sich als günstig, die Stege gemäß Anspruch 4 anzuordnen und dabei diese Stege beabstandet auszubilden gemäß Anspruch 5.It proves to be advantageous to arrange the webs according to claim 4 and to form these webs at a distance from one another according to claim 5.
Erhöht werden die Festigkeitseigenschaften durch die Ausbildung der Zahnräder gemäß Anspruch 6.The strength properties are increased by the design of the gears according to claim 6.
Anhand eines abgebildeten Ausführungsbeispieles wird die Erfindung im Folgenden näher erläutert.The invention is explained in more detail below using an illustrated embodiment.

Fig. 3: die Abwinklung eines Kreisschnittes gemäß der Schnittlinie U in Figur 1. Fig. 3: the bending of a circular section according to the section line U in Figure 1.
Die Nabe 3 und der Außenzahnkranz 1 sind einstückig verbunden durch speichenartige Stege 2. Wie insbesondere aus den Figuren 2 und 3 ersichtlich, sind diese Stege jeweils abwechselnd in gleichmäßiger Umfangsverteilung in einer zur Mittelebene EM parallelen Ebene E1 bzw. E2 angeordnet. Die Stege haben dabei einen Abstand zur Mittelebene EM. Gebildet sind diese Stege 2 als Abschnitt einer den Zahnkranz 1 innen &iacgr;&ogr; und die Nabe 3 außen verbindenden gedachten Scheibe, die in Umfangsrichtung als periodische Kreisfunktion profiliert ist. Dabei sind diese Stege 2 jeweils in den Maximalamplitudenbereichen der Kreisfunktion gebildet.The hub 3 and the external gear rim 1 are connected in one piece by spoke-like webs 2. As can be seen in particular from Figures 2 and 3, these webs are arranged alternately in a uniform circumferential distribution in a plane E 1 or E 2 parallel to the center plane E M . The webs are at a distance from the center plane E M . These webs 2 are formed as a section of an imaginary disk connecting the gear rim 1 on the inside and the hub 3 on the outside, which is profiled in the circumferential direction as a periodic circular function. These webs 2 are each formed in the maximum amplitude ranges of the circular function.
Die Anbindung der Stege 2 sowohl an der Innenseite des Außenzahnkranzes 1 als auch an der Außenseite der Nabe 3 ist mit verbreiterten Übergangsbereichen 21 bzw. 22 vorgesehen.The connection of the webs 2 both on the inside of the external gear rim 1 and on the outside of the hub 3 is provided with widened transition areas 21 and 22, respectively.
