Abstract
Description
Die Erfindung bezieht sich auf ein Planetengetriebe nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a planetary gear according to the preamble Of claim 1 further defined type.
Bei Planetengetriebe wird, um das Geräuschverhalten zu verbessern, ein gleichzeitiger Zahneingriff der Verzahnung der Planetenräder in die Verzahnung des inneren Zentralrads angestrebt. Um dies zu erreichen, muss die Zähnezahl des inneren Zentralrades ganzzahlig durch die Anzahl der Planetenräder teilbar sein.at Planetary gear is used to improve the noise behavior, a simultaneous meshing of the teeth of the planetary gears sought in the teeth of the inner central wheel. To this, too must reach the number of teeth of the inner central wheel be integer divisible by the number of planetary gears.
Die
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde ein Planetengetriebe zu schaffen, welches einen gleichzeitigen Zahneingriff der Verzahnung der Planetenräder in die Verzahnung des inneren Zentralrades aufweist, und bei welchem die Anzahl der Planetenräder frei wählbar ist, ohne die Zähnezahl des inneren Zentralrades zu verändern.Of the present invention, the object is based on a planetary gear to create a simultaneous meshing of the teeth the planet gears in the teeth of the inner central wheel and in which the number of planet gears is freely selectable, without the number of teeth of the inner Central wheel to change.
Die Aufgabe wird mit einem auch die kennzeichnenden Merkmale des Hauptanspruches aufweisenden gattungsgemäßen Planetengetriebe gelöst.The Task is with a also the characterizing features of the main claim having generic planetary gear solved.
Erfindungsgemäß weist das Planetengetriebe ein Zentralrad, ein Hohlrad und einen Planetenträger mit auf diesem gelagerten Planetenrädern auf, wobei die Zähnezahl des inneren Zentralrades nicht ganzzahlig durch die Anzahl der Planetenräder teilbar ist. Die Planetenachse, welche einerseits durch die Drehachse des inne ren Zentralrades und andererseits durch die Drehachse des Planetenrades gehen, sind nicht gleichmäßig verteilt angeordnet, so dass nicht immer die gleichen Winkel zwischen den Planetenachsen vorhanden sind, sondern die Planetenachsen werden so verschoben, dass ein nahezu gleichzeitiger Zahneingriff stattfindet. Vorzugsweise werden die Planetenachsen so verschoben, dass bei insgesamt drei Planetenrädern zwei Winkel den gleichen etwas verringerten Betrag aufweisen und ein Winkel einen höheren Betrag aufweist.According to the invention the planetary gear a central gear, a ring gear and a planet carrier with mounted on this planetary gears, the Number of teeth of the inner central wheel not integer by the number of planet gears is divisible. The planet axis, which on the one hand by the axis of rotation of the holding Ren central wheel and on the other hand go through the axis of rotation of the planetary gear are not arranged evenly distributed, so not always the same angles between the planetary axes present but the planetary axes are shifted so that one almost simultaneous tooth engagement takes place. Preferably the planetary axes shifted so that with a total of three planetary gears two angles have the same slightly reduced amount and an angle has a higher amount.
In einer weiteren Ausgestaltungsform der Erfindung wird die gleichzeitige Zahneingriffsfolge weiter verbessert, indem die Verzahnung beispielsweise durch Profilverschiebung oder Verzahnungskorrekturen weiter angepasst werden.In Another embodiment of the invention is the simultaneous Tooth engagement sequence further improved by the teeth, for example, by Profile shift or gear corrections further adapted become.
Somit besteht die Möglichkeit ein Planetengetriebe sowohl mit drei als auch mit vier Planeten herzustellen, ohne die Zähnezahl des inneren Zentralrades zu verändern, wobei beispielsweise sowohl Getriebe mit drei Planeten als auch Getriebe mit vier Planeten eine gleichzeitige Zahneingriffsfolge aufweisen, ohne die Zähnezahl des inneren Zentralrades zu verändern.Consequently there is the possibility of a planetary gear both with three as well as with four planets, without the number of teeth to change the inner central wheel, for example both three planetary gearboxes and four planetary gearboxes have a simultaneous tooth engagement sequence, without the number of teeth to change the inner central wheel.
Weitere Merkmale sind der Figurenbeschreibung zu entnehmen.Further Features are shown in the description of the figures.
Die
einzige Figur zeigt ein Planetengetriebe mit einem Hohlrad
Somit ist es möglich das Planetengetriebe mit einem Sonnenrad mit einer Zähnezahl 16 sowohl mit drei als auch mit vier Planeten auszuführen und in beiden Ausführungen einen gleichzeitigen Zahneingriff zu erreichen.Consequently Is it possible the planetary gear with a sun gear with a number of teeth 16 with both three and four Planets perform and in both versions to achieve a simultaneous meshing.
