Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Planetengetriebe, umfassend wenigstens einen Planetenradträger mit zwei parallel zueinander verlaufenden Seitenwänden mit daran einander gegenüberliegenden Axialbohrungen, wobei zwischen den Seitenwänden ein oder mehrere Planetenräder drehbar angeordnet sind.The invention relates to a planetary gear, comprising at least one planet carrier with two mutually parallel side walls with opposite axial bores, wherein one or more planetary gears are rotatably arranged between the side walls.
Hintergrund der ErfindungBackground of the invention
Planetengetriebe sind in unterschiedlichen Bauformen bekannt. Ihnen gemein ist ein Planetenradträger mit zwei parallel zueinander verlaufenden, kraftschlüssig miteinander verbundenen Seitenwänden, die in mehreren jeweils achsgleich gegenüberliegenden Axialbohrungen eine Mehrzahl von Planetenradbolzen aufnehmen, auf denen jeweils ein Planetenrad über in eine zentrale Planetenradbohrung eingesetzte Nadelhülsen drehgelagert ist. In an sich bekannter Weise kämmen die Planetenräder mit einem zentralen Sonnenrad. Die Planetenräder weisen üblicherweise eine Schrägverzahnung auf. Durch diese Schrägverzahnung kommt es zu einem axialen Wandern der Planetenräder, d. h., dass sich die Planetenträger je nach Drehrichtung in Richtung der einen oder anderen Seitenwand bewegen. Um zu vermeiden, dass sich die Planetenräder direkt an die Seitenwand anlegen, sind an den Axialseiten der Planetenräder ringscheibenförmige Anlaufelemente angeordnet, welche als Verschleißschutz des Planetenradträgers gegenüber den Planetenrädern und als Axialanlauf für die Nadelhülsen der Planetenräder dienen. Kommt es zu einem axialen Wandern, so laufen die Anlaufelemente gegen die Seitenwände. Zwar kann hierdurch das jeweilige Planetenrad geschützt werden, jedoch kommt es infolge des Anlaufs zu einer erhöhten Reibung. Auch ist die Montage respektive Integration der Anlaufelemente mit höherem Aufwand und somit höheren Kosten verbunden.Planetary gears are known in different designs. Common to them is a planet carrier with two mutually parallel, frictionally interconnected side walls, which receive a plurality of Planetenradbolzen in several axially opposite axial bores, on each of which a planetary gear is rotatably mounted via inserted into a central Planetenradbohrung needle sleeves. In known manner, the planetary gears mesh with a central sun gear. The planet gears usually have a helical toothing. Due to this helical toothing, there is an axial migration of the planet gears, d. h. That move the planet carrier depending on the direction of rotation in the direction of one or the other side wall. In order to avoid that the planetary gears create directly on the side wall, ring-shaped starting elements are arranged on the axial sides of the planetary gears, which serve as wear protection of the planet carrier relative to the planetary gears and as an axial approach for the needle sleeves of the planetary gears. If it comes to an axial migration, the run-up elements run against the side walls. Although this allows the respective planetary gear to be protected, however, as a result of the startup, increased friction occurs. The assembly respectively integration of the starting elements is associated with higher costs and thus higher costs.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt damit die Aufgabe zugrunde, ein demgegenüber verbessertes, einfach aufgebautes Planetengetriebe anzugeben.The invention is therefore an object of the invention to provide a contrast improved, simply constructed planetary gear.
Beschreibung der ErfindungDescription of the invention
Zur Lösung dieses Problems ist bei einem Planetengetriebe der eingangs genannten Art erfindungsgemäß vorgesehen, dass am Planetenrad beidseits der Drehlagerung dienende Kegelzapfen vorgesehen sind, dass die Axialbohrungen als Kegelbohrungen ausgeführt sind, und dass jeder Kegelzapfen in der Kegelbohrung über ein schräges Wälzlager drehgelagert ist.To solve this problem is provided according to the invention in a planetary gear of the type mentioned that the planetary gear on both sides of the rotary bearing serving taper are provided that the axial bores are designed as tapered holes, and that each taper is rotatably mounted in the tapered bore via an oblique roller bearing.
Erfindungsgemäß ist jedes Planetenrad über eine Kegellagerung an den Seitenwänden drehgelagert. Hierzu sind am jeweiligen Planetenrad beidseits entsprechende Kegelzapfen vorgesehen, die in seitenwandseitige Kegelbohrungen eingreifen. An den Zapfen oder in den Bohrungen ist jeweils ein schräg ausgeführtes Wälzlager angeordnet, also ein Wälzlager, dessen Wälzkörper um eine schräg zur Planetenraddrehachse stehende Achsen rotieren. Die Wälzkörper bestehen in diesem Fall lediglich aus den in einem Käfig aufgenommenen Wälzkörpern, sie wälzen unmittelbar auf den Mantelflächen der Kegelzapfen und der Kegelbohrungen ab. Die Wälzlager sind bevorzugt leicht vorgespannt.According to the invention, each planet gear is rotatably mounted on the side walls via a tapered bearing. For this purpose, on both sides corresponding tapered cones are provided on the respective planetary gear, which engage in side wall-side tapered holes. At the pin or in the bores in each case an obliquely executed rolling bearing is arranged, that is, a roller bearing, the rolling elements rotate about an axis perpendicular to the Planetenraddrehachse axes. The rolling elements consist in this case only of the rolling elements received in a cage, they roll directly on the lateral surfaces of the taper and the tapered holes. The rolling bearings are preferably slightly biased.
Durch diese erfindungsgemäße Kegellagerung werden die Planetenräder mit besonderem Vorteil sowohl axial als auch radial an den Seitenwänden abgestützt. Da die Planetenräder fest mit den Kegelzapfen verbunden sind, kann es folglich zu keinerlei axialer Wanderbewegung kommen. Aus diesem Grund sind bei dem erfindungsgemäßen Planetengetriebe auch keine Anlaufelemente, also Anlaufscheiben, erforderlich, da etwaige aus dem Schrägverzahnungseingriff resultierende, in Drehachsrichtung gegebene Kräfte über die Kegellagerung aufgenommen werden. Ein Anliegen eines Planetenrades an eine Seitenwand ist damit ohne zusätzliches Bauteil ausgeschlossen, es kann zu keinerlei Reibung zwischen dem Planetenrad und dem Planetenradträger kommen.As a result of this conical bearing according to the invention, the planet wheels are supported with particular advantage both axially and radially on the side walls. Since the planetary gears are firmly connected to the taper, it can therefore come to any axial migration movement. For this reason, in the planetary gear according to the invention also no starting elements, so thrust washers required because any resulting from the helical gear, given in Drehachsrichtung forces are absorbed via the tapered bearing. A concern of a planetary gear on a side wall is thus excluded without additional component, it can come to no friction between the planet and the planet carrier.
Als Wälzlager kann beispielsweise ein Schrägnadellager verwendet werden. Da die Nadeln über ihre gesamte Länge den gleichen Durchmesser aufweisen, sind folglich die Kegelwinkel des jeweiligen Kegelzapfens sowie der Kegelbohrung gleich. Alternativ zu einem schrägen Nadellager kann auch ein Kegelrollenlager verwendet werden. Der Durchmesser der Kegelrollen erweitert sich, so dass folglich, der Durchmesseränderung der Kegelrollen folgend, auch die Kegelwinkel des jeweiligen Kegelzapfens und der entsprechenden Kegelbohrung unterschiedlich sind.As a rolling bearing, for example, a helical needle bearings can be used. Since the needles have the same diameter over their entire length, consequently, the cone angle of the respective taper and the conical bore are the same. As an alternative to a tapered needle bearing, a tapered roller bearing can also be used. The diameter of the tapered rollers expands, so that, consequently, following the change in diameter of the tapered rollers, the taper angles of the respective tapered pin and the corresponding tapered hole are different.
Die Mantelflächen der Kegelbohrungen und der Kegelzapfen sind bevorzugt gehärtet, so dass eine hohe Verschleißfestigkeit gegeben ist.The lateral surfaces of the conical bores and the taper are preferably hardened, so that a high wear resistance is given.
Bevorzugt sind die Kegelzapfen einstückig am Planetenrad angeformt, was in einem entsprechenden Schmiedeprozess oder materialabtragenden Fertigungsprozess erfolgen kann. Grundsätzlich wäre es aber auch denkbar, die Kegelzapfen separat zu fertigen und an den Planetenradseiten stoffschlüssig anzubringen.Preferably, the cones are integrally formed on the planet gear, which can be done in a corresponding forging process or material-removing manufacturing process. In principle, however, it would also be conceivable to manufacture the tapered pins separately and to attach them to the planetary gear sides in a material-locking manner.
