Description
Die vorliegende Erfindung betrifft eine Ladeeinrichtung, insbesondere einen Abgasturbolader einer Brennkraftmaschine eines Kraftfahrzeuges, gemäß dem Oberbegriff des Anspruchs 1. The present invention relates to a charging device, in particular an exhaust gas turbocharger of an internal combustion engine of a motor vehicle, according to the preamble of claim 1.
Aus der
Aus der
Bei den aus dem Stand der Technik bekannten Ladeeinrichtungen ist die Verdrehsicherung der Außenhülse des Wälzlagers über mehrere separate Teile realisiert, was jedoch einerseits teuer und andererseits aufwändig zu montieren ist. In the known from the prior art charging devices, the rotation of the outer sleeve of the bearing is realized via a plurality of separate parts, which, however, on the one hand expensive and expensive to install on the other hand.
Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für eine Ladeeinrichtung der gattungsgemäßen Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch einen konstruktiv einfachen Aufbau und eine reduzierte Teilevielfalt auszeichnet. The present invention therefore deals with the problem of providing for a charging device of the generic type an improved embodiment, which is characterized in particular by a structurally simple structure and a reduced variety of parts.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine Außenhülse eines Wälzlagers für eine Welle in einer Ladeeinrichtung nicht mehr über separate Fixiereinrichtungen drehfest zu fixieren, sondern über einen Lagergehäusedeckel, der über eine Formschlussverbindung drehfest mit der Außenhülse fixiert werden kann. Die erfindungsgemäße Ladeeinrichtung, die bspw. als Abgasturbolader in einer Brennkraftmaschine in einem Kraftfahrzeug ausgebildet sein kann, weist dabei in bekannter Weise eine ein Turbinenrad und ein Verdichterrad tragende Welle auf, die über das Wälzlager in einem Lagergehäuse der Ladeeinrichtung gelagert ist. Das Wälzlager wiederum umfasst die zuvor erwähnte Außenhülse, über die es mit dem Lagergehäuse in Kontakt steht. Die Außenhülse kann dabei direkt oder indirekt über eine äußere Hülse mit Wälzkörpern des Wälzlagers in Kontakt stehen. Verdichterseitig ist das Lagergehäuse vom Lagergehäusedeckel gegenüber dem Verdichter abgeschlossen. Um nun die Außenhülse drehfest im Lagergehäuse fixieren zu können, ist angedacht, die Außenhülse und den Lagergehäusedeckel über eine Formschlussverbindung drehfest miteinander zu verbinden. Da der Lagergehäusedeckel üblicherweise selbst drehfest bspw. am Verdichtergehäuse fixiert wird, kann über diesen auch eine Verdrehsicherung für die Außenhülse des Wälzlagers realisiert werden, ohne dass hierfür zusätzliche Fixiermittel, wie bspw. Schrauben, erforderlich wären. Bei der erfindungsgemäßen Ladeeinrichtung reduziert sich somit die Teilevielfalt über die wegfallenden Fixiermittel, wie bspw. die wegfallenden Schrauben, wobei zugleich die Montage vereinfacht werden kann, da die Außenhülse über eine insbesondere einfach zu verbindende Steckverbindung drehfest mit dem Lagergehäusedeckel fixiert wird. The present invention is based on the general idea of no longer fixating an outer sleeve of a roller bearing for a shaft in a charging device via separate fixing devices, but via a bearing housing cover, which can be fixed in a rotationally fixed manner with the outer sleeve via a form-locking connection. The charging device according to the invention, which may be formed, for example, as an exhaust gas turbocharger in an internal combustion engine in a motor vehicle, has in a known manner a turbine wheel and a compressor wheel bearing shaft which is mounted on the rolling bearing in a bearing housing of the charger. The rolling bearing in turn comprises the aforementioned outer sleeve, via which it is in contact with the bearing housing. The outer sleeve can be directly or indirectly via an outer sleeve with rolling elements of the bearing in contact. Compressor side, the bearing housing is completed from the bearing housing cover opposite the compressor. In order to fix the outer sleeve rotatably in the bearing housing, it is envisaged to connect the outer sleeve and the bearing housing cover in rotation with each other via a positive connection. Since the bearing housing cover is usually self-rotatably, for example. Is fixed to the compressor housing, it can be realized on this, a rotation for the outer sleeve of the bearing, without requiring additional fixing, such as. Screws would be required. In the charging device according to the invention thus reduces the variety of parts on the eliminated fixative, such as the omitted screws, at the same time the assembly can be simplified, since the outer sleeve is fixed in rotation with the bearing housing cover via a particular simple to connect connector.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung weist die Außenhülse oder der Lagergehäusedeckel zumindest einen axial abstehenden Steg auf, der in eine an dem Lagergehäusedeckel oder an der Außenhülse angeordnete und komplementär dazu ausgebildete Ausnehmung eingreift und dadurch die Formschlussverbindung realisiert. Generell können selbstverständlich auch mehrere, insbesondere drei abstehenden Stege an dem Lagergehäusedeckel vorgesehen sein, die in Umfangsrichtung gleichmäßig verteilt, also bspw. um 120° versetzt, angeordnet sind. Die formschlüssige Verbindung erfolgt nun durch ein einfaches Eingreifen der lagergehäusedeckelseitigen Stege in die außenhülsenseitigen Ausnehmungen, ohne dass hierfür weitere Fixiermittel, wie bspw. Schrauben, vorgesehen werden müssten. Hierdurch lässt sich die Teilevielfalt reduzieren und zugleich der Montageaufwand verringern. In an advantageous development of the solution according to the invention, the outer sleeve or the bearing housing cover at least one axially projecting web, which engages in a arranged on the bearing housing cover or on the outer sleeve and complementarily formed recess and thereby realizes the form-locking connection. In general, of course, several, in particular three protruding webs may be provided on the bearing housing cover evenly distributed in the circumferential direction, ie, for example, offset by 120 °, are arranged. The positive connection is now carried out by a simple intervention of the bearing housing cover side webs in the outer sleeve-side recesses, without the need for further fixation, such as screws, would have to be provided. This can reduce the variety of parts and at the same time reduce assembly costs.
Zweckmäßig bildet der Lagergehäusedeckel zugleich eine Verdichtergehäuserückwand. In diesem Fall ist somit dem Lagergehäusedeckel zusätzlich eine weitere Funktion, nämlich die Bildung der Verdichtergehäuserückwand, zugedacht, wodurch eine bisher separate Verdichtergehäuserückwand entbehrlich ist und dadurch wiederum die Teilevielfalt und der Montageaufwand reduziert werden kann. Suitably, the bearing housing cover also forms a compressor housing rear wall. In this case, therefore, the bearing housing cover is additionally a further function, namely the formation of the compressor housing rear wall, intended, so that a previously separate compressor housing rear wall is unnecessary and in turn the variety of parts and assembly costs can be reduced.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung sind/ist der Lagergehäusedeckel und/oder die Außenhülse des Wälzlagers aus Kunststoff ausgebildet, insbesondere aus Polyetheretherketon (PEEK), Polytetrafluorethylen (PTFE), Polyamid (PA), Acetal, amorpher thermoplastisches Polyetherimid, Polyamidimid (PAI), Polybenzimidazol (PBI) oder aus einem nichtmetallischen hochtemperaturbeständigen Kompositwerkstoff mit geringer Leitfähigkeit. Bereits diese Aufzählung lässt erahnen, welch mannigfaltig unterschiedliche Kunststoffe für den Lagergehäusedeckel und/oder die Außenhülse eingesetzt werden können, wobei diese Kunststoffe individuelle Eigenschaften aufweisen und insbesondere an dort auftretende Temperaturen bzw. mechanische Belastungen angepasst werden können. Derartige aus Kunststoff ausgebildete Lagergehäusedeckel bzw. Außenhülsen lassen sich nicht nur fertigungstechnisch einfach und hoch präzise sondern zudem auch kostengünstig herstellen.In a further advantageous embodiment of the solution according to the invention, the bearing housing cover and / or the outer sleeve of the rolling bearing are / is made of plastic, in particular polyetheretherketone (PEEK), polytetrafluoroethylene (PTFE), polyamide (PA), acetal, amorphous thermoplastic polyetherimide, polyamideimide (PAI ) Polybenzimidazole (PBI) or from a non-metallic high temperature resistant composite material with low conductivity. Already this list gives an idea of the variety of different plastics for the bearing housing cover and / or the outer sleeve can be used, these plastics have individual properties and can be adapted in particular to temperatures occurring there or mechanical loads. Such formed from plastic bearing housing cover or outer sleeves can be produced not only in terms of manufacturing technology simple and high-precision but also cost-effective.
Zweckmäßig besitzt der Lagergehäusedeckel einen Wellendichtungsbereich. Bei der Ausbildung des Lagergehäusedeckels kann somit vorgesehen sein, an diesem gleichzeitig einen Wellendichtungsbereich vorzusehen, bspw. anzuspritzen, wodurch weitere, bisher separat zu montierende Bauteile, entbehrlich sind. Auch hierdurch lassen sich die Teilevielfalt und verbunden damit die Lager- und Logistikkosten reduzieren. Suitably, the bearing housing cover has a shaft seal area. In the formation of the bearing housing cover can thus be provided to provide this at the same time a shaft seal area, for example. To inject, whereby further, previously separately to be mounted components are unnecessary. This also makes it possible to reduce the variety of parts and, associated with it, the storage and logistics costs.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung ist zwischen der Außenhülse und der äußeren Hülse ein Ölfilm zur Schwingungsentkopplung vorgesehen. Ein derartiger (Quetsch-)Ölfilm bewirkt eine schwimmende Lagerung der äußeren Hülse relativ zum Lagergehäuse, wodurch diese schwingungsdämpfend gelagert ist und insbesondere eine Schwingungsübertragung vom Rotor auf das Lagergehäuse nahezu unterbunden wird. Die Schwingungsentkopplung wird dabei zusätzlich dadurch reduziert, dass die Außenhülse vorzugsweise aus Kunststoff ausgebildet ist und dadurch im Vergleich zu einer metallischen Außenhülse schwingungsdämpfend wirkt. In a further advantageous embodiment of the solution according to the invention, an oil film for vibration decoupling is provided between the outer sleeve and the outer sleeve. Such a (squeezing) oil film causes a floating mounting of the outer sleeve relative to the bearing housing, whereby this is mounted vibration damping and in particular a vibration transmission from the rotor to the bearing housing is almost prevented. The vibration decoupling is additionally reduced by the fact that the outer sleeve is preferably made of plastic and thereby acts as a vibration damping in comparison to a metallic outer sleeve.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung ist die Außenhülse in das Lagergehäuse eingelegt oder eingepresst. Die Außenhülse kann dadurch im Lagergehäuse vormontiert werden. Nach dem ersten Temperaturwechsel ist diese Presspassung aber nicht mehr vorhanden und die Verdrehsicherung erfolgt ausschließlich über die Formschlussverbindung mit dem Lagergehäusedeckel. Die Außenhülse weist selbstverständlich weitere Öffnungen auf, wie bspw. Ölzulauf- und Ölablauföffnungen, welche zugleich bspw. als Blende dienen können. In a further advantageous embodiment of the solution according to the invention, the outer sleeve is inserted or pressed into the bearing housing. The outer sleeve can be pre-assembled in the bearing housing. After the first temperature change, however, this press fit is no longer present and the rotation is ensured exclusively via the form-locking connection with the bearing housing cover. The outer sleeve has, of course, other openings, such as. Oil inlet and oil drain holes, which at the same time, for example, can serve as a diaphragm.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
