Abstract

Die Erfindung betrifft eine Anordnung mit einem Planetenträger, mindestens einem in dem Planetenträger fixierten Planetenschaft und mindestens ein Planetenrad; wobei der Planetenschaft als einstückiger Flex-Pin ausgestaltet ist; gekennzeichnet durch ein oder mehrere Gleitlager, mit denen das Planetenrad auf dem Planetenschaft gelagert ist.The invention relates to an arrangement with a planet carrier, at least one planet shaft fixed in the planet carrier and at least one planet gear; wherein the planet shaft is designed as a one-piece flex pin; characterized by one or more plain bearings with which the planet gear is mounted on the planet shaft.

Description

Die Erfindung betrifft eine Anordnung nach dem Oberbegriff von Anspruch 1.The invention relates to an arrangement according to the preamble of claim 1.

Aus dem Stand der Technik sind sogenannte Flex-Pins bekannt. Hierbei handelt es sich um Planetenbolzen, die nachgiebig ausgestaltet sind. Ziel ist eine ausgeglichene Lastverteilung in den Zahneingriffen einer Planetenstufe. Die Druckschrift US 3303713 A beschreibt die Funktionsweise und den Aufbau eines Flex-Pins.So-called flex pins are known from the prior art. These are planet bolts that are designed to be flexible. The goal is a balanced load distribution in the meshing of a planetary stage. The publication US 3303713 A describes the functionality and structure of a flex pin.

Aus 3 der Druckschrift EP 1399682 B1 und der zugehörigen Beschreibung sind einstückig ausgeführte Flex-Pins bekannt. Die Planetenräder sind hier mittels Kegelrollenlager auf den Flex-Pins gelagert.Out 3rd the publication EP 1399682 B1 and the associated description of one-piece flex pins are known. The planet gears are mounted on the flex pins by means of tapered roller bearings.

Der Erfindung liegt die Aufgabe zugrunde, die Lagerung eines Planetenrads auf einem Flex-Pin zu verbessern. Insbesondere soll die Lagerung robuster gestaltet werden.The invention has for its object to improve the mounting of a planet gear on a flex pin. In particular, the storage should be made more robust.

Diese Aufgabe wird gelöst durch eine Anordnung nach Anspruch 1. Die Anordnung umfasst einen Planetenträger, mindestens einen in dem Planetenträger fixierten Planetenschaft und mindestens ein Planetenrad. Hierbei handelt es sich um Komponenten für eine Planetenstufe, die darüber hinaus ein Hohlrad und ein Sonnenrad aufweist. Das Planetenrad ist drehbar auf dem Planetenschaft gelagert und kämmt mit dem Sonnenrad und/oder dem Hohlrad. Mindestens zwei der drei Komponenten Planetenträger, Hohlrad und Sonnenrad sind um eine gemeinsame Drehachse drehbar gelagert. Die dritte Komponente kann ebenfalls um diese Drehachse drehbar gelagert oder drehfest fixiert sein.This object is achieved by an arrangement according to claim 1. The arrangement comprises a planet carrier, at least one planet shaft fixed in the planet carrier and at least one planet gear. These are components for a planetary stage, which also has a ring gear and a sun gear. The planet gear is rotatably mounted on the planet shaft and meshes with the sun gear and / or the ring gear. At least two of the three components planet carrier, ring gear and sun gear are rotatably mounted about a common axis of rotation. The third component can also be mounted rotatably about this axis of rotation or fixed in a rotationally fixed manner.

Der Planetenschaft ist als einstückiger Flex-Pin ausgestaltet. Ein einstückiger Flex-Pin lässt sich etwa durch Gießen oder mittels eines additiven Fertigungsverfahrens herstellen.The planet shaft is designed as a one-piece flex pin. A one-piece Flex-Pin can be manufactured, for example, by casting or using an additive manufacturing process.

Erfindungsgemäß weist die Anordnung ein oder mehrere Gleitlager auf. Mit den Gleitlagern ist das Planetenrad drehbar auf dem Planetenschaft gelagert. Vorzugsweise ist das Planetenrad ausschließlich mittels der Gleitlager gelagert. Bei den Gleitlagern handelt es sich bevorzugt um kegelförmige Gleitlager in O-Anordnung.According to the invention, the arrangement has one or more plain bearings. With the slide bearings, the planet gear is rotatably mounted on the planet shaft. The planet gear is preferably mounted exclusively by means of the slide bearings. The plain bearings are preferably conical plain bearings in an O arrangement.
