Abstract
Description
Die Erfindung betrifft eine elektrische Maschine, insbesondere Fahrmotor für Schienenfahrzeuge, mit einem Ständer, in dem über ein mittels Fett geschmier tes Wälzlager ein Läufer drehbar angeordnet ist, wobei der Läufer mit einer Antriebswelle für einen Radsatz und das Wälzlager mit einer Nach schmiereinrichtung verbunden sind.The invention relates to an electrical machine, in particular traction motor for Rail vehicles, with a stand in which a grease lubricated tes roller bearing a rotor is rotatably arranged, the rotor with a Drive shaft for a wheel set and the roller bearing with one after lubrication device are connected.
Der Einbau einer Nachschmiereinrichtung für Wälzlager in elektrischen Maschi nen ist immer dann notwendig, wenn ein Motor einer hohen radialen Belastung und/oder abnormalen Umwelteinflüssen (z. B. Temperatur) ausgesetzt ist. Derartige Nachschmierungen lassen sich nach dem bisherigen Stand der Tech nik wie folgt realisieren:The installation of a regreasing device for rolling bearings in electrical machines NEN is always necessary when an engine has a high radial load and / or is exposed to abnormal environmental influences (e.g. temperature). Such relubrication can be done according to the current state of the art Realize as follows:
Ein Lagergehäuse weist abgedichtete Aussparungen zum Wälzlager hin auf, die mit Fett vollgefüllt sind. Nachteilig dabei ist, daß erstens beim Nachfetten die Gefahr besteht, daß verschmutztes, zum Teil verharztes Fett zurück in die Laufbahn gelangt und zweitens ein solches Lager bei einer Nachfettaktion demontiert werden muß (DE-OS 26 35 172).A bearing housing has sealed recesses to the rolling bearing, which are filled with fat. The disadvantage here is that, firstly, when relubricating There is a risk that contaminated, partly gummy grease returns to the Career and secondly such a camp in a re-greasing campaign must be dismantled (DE-OS 26 35 172).
Bei der Lagerung eines Rotors einer elektrischen Maschine wird der Austritt von Fett durch Anordnung von Fettstauwänden verhindert. Beim Nachschmieren wird das alte Fett an den Fettstauwänden heruntergedrückt und durch eine mit der Rotorwelle verbundene Schleuderscheibe nach außen abgeschleudert. Nachteilig ist die durch Fettstauwände und Schleuderscheibe bedingte auf wendige Konstruktion einer solchen Einrichtung. Auch hier besteht die Gefahr, daß beim Nachschmieren verschmutztes Fett in den Laufbahnbereich gelangt (DE-OS 23 01 204).When storing a rotor of an electrical machine, the exit of Prevents fat by arranging fat storage walls. When relubricating the old fat is pressed down on the fat storage walls and with a centrifugal disc connected to the rotor shaft is thrown outwards. The disadvantage is that caused by grease retaining walls and the centrifugal disc agile construction of such a device. There is also a risk here that contaminated grease gets into the raceway area when relubricating (DE-OS 23 01 204).
Schließlich ist ein Wälzlager eines Elektromotors beschrieben, in dem das Fett über ein Röhrensystem, eine Fettkammer und ein kegelförmiges Rotationsele ment von einer Seite zugeführt wird und an der anderen Seite nach Durch queren des Wälzlagers über eine weitere Kammer und eine zugehörige Öffnung austreten kann. Diese kontinuierliche Nachschmierung verhindert zwar ein Eindringen von altem Fett in das Lager, ist aber nur sehr aufwendig zu realisie ren (DE-AS 26 09 915).Finally, a roller bearing of an electric motor is described in which the grease via a tube system, a fat chamber and a conical rotary element ment is fed from one side and on the other side after through cross the rolling bearing through another chamber and an associated opening can leak. This continuous relubrication prevents Penetration of old grease into the bearing is, however, very difficult to achieve ren (DE-AS 26 09 915).
Der Erfindung liegt daher die Aufgabe zugrunde, für die Lagerung von elek trischen Maschinen der eingangs geschilderten Art eine einfache und kostengün stige Nachschmiereinrichtung zu entwickeln.The invention is therefore based on the object for the storage of elek trical machines of the type described a simple and inexpensive to develop permanent relubrication equipment.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 dadurch gelöst, daß die Nachschmiereinrichtung als eine Öl abge bende Patrone ausgebildet ist.According to the invention, this task is performed according to the characterizing part of Claim 1 solved in that the relubrication device abge as an oil cartridge is formed.
Durch das Nachführen von Öl aus einer Patrone an das zur Schmierung not wendige Fett wird dessen Gebrauchsdauer erhöht, d. h. bei derartig fettge schmierten Lagern verlängern sich die Wartungsintervalle entscheidend. Damit wird es möglich, aufwendige Demontagen der Lagerung zu vermeiden bzw. hinauszuschieben. Bei der üblichen Fettschmierung, d. h. wenn kein Öl nach geführt wird, verfestigt sich das Fett durch Abgeben des Öls (Ausbluten). Wenn die Hälfte des Öls durch Verdampfen oder Ausbluten verlorengegangen ist, hat das Schmierfett seine Schmiereigenschaften verloren und muß ausgetauscht werden. Dieses Austauschen von verbrauchtem Fett wird durch die Erfindung verhindert bzw. weit hinausgeschoben, da es durch Ölzugabe vor dem Aus trocknen bewahrt und immer frisch gehalten wird.By adding oil from a cartridge to the one that is necessary for lubrication Agile fat increases its useful life, d. H. with such fat Lubricated bearings significantly extend the maintenance intervals. In order to it becomes possible to avoid expensive dismantling of the storage or postpone. With the usual grease lubrication, i.e. H. if no oil after the fat solidifies by releasing the oil (bleeding). If half of the oil has been lost through evaporation or bleeding the grease lost its lubricating properties and must be replaced will. This exchange of used fat is accomplished by the invention prevented or pushed far out, as it is by adding oil before the end keep dry and always kept fresh.
Vorteilhafte Ausführungen der erfindungsgemäßen Lösung sind in den Unter ansprüchen 2 bis 4 beschrieben.Advantageous embodiments of the solution according to the invention are in the sub claims 2 to 4 described.
So ist nach Anspruch 2 vorgesehen, daß die Patrone aus einer durchbrochenen Ummantelung besteht, die einen Schaumstoff, einen Filz oder ein Textilgewebe umschließt. Eine solche Ausbildung der Patrone garantiert einerseits das Ent stehen einer festen Form und andererseits ein problemloses Nachfüllen von Öl durch die Unterbrechungen.It is provided according to claim 2 that the cartridge from an openwork Sheathing consists of a foam, a felt or a textile fabric encloses. Such a design of the cartridge guarantees the Ent on the one hand have a solid shape and, on the other hand, easy refilling of oil through the interruptions.
In vorteilhafter Weiterbildung der Erfindung nach Anspruch 3 soll der Schaum stoff ein Polyurethanester sein. Dieser Schaumstoff soll weitgehend geöffnete, bzw. völlig geöffnete Poren aufweisen, um ein möglichst hohes Speicherver mögen für das Öl zu gewährleisten. Polyurethan ist besonders ölbeständig und vergrößert sein Volumen bei Ölaufnahme aufgrund seiner porigen Struktur nur unwesentlich.In an advantageous development of the invention according to claim 3, the foam be a polyurethane ester. This foam is said to be largely open, or have completely open pores in order to maximize the storage capacity like to ensure for the oil. Polyurethane is particularly oil-resistant and only increases its volume when oil is absorbed due to its porous structure insignificant.
Schließlich soll nach Anspruch 4 die Patrone im Bereich einer Ölzuführungs bohrung angeordnet sein. Auf diese Weise wird eine nochmalige Verlängerung des Fettwechsels erreicht, da die leere Patrone problemlos mit Öl von außen nachgefüllt werden kann.Finally, according to claim 4, the cartridge in the area of an oil supply hole be arranged. In this way there will be another renewal the fat change is achieved because the empty cartridge easily with oil from the outside can be refilled.
Die Erfindung wird an nachstehendem Ausführungsbeispiel näher erläutert. The invention is explained in more detail using the following exemplary embodiment.
