Abstract

The gearbox has a housing on which is an oil-collector (4) above the oil-level, for removing foreign particles. The oil-collector (4) has at least one top inlet, and oil-outlet formed by a hole (6) in a wall (8-10) of the container (4). The hole (6) is closed by a filter (11) which possesses uneven porosity, is uneven in thickness and has magnetic wires woven through it. USE/ADVANTAGE - The oil in the gearbox is relatively quickly cleaned, even if the volume of the oil collector container is small.

Description

Die Erfindung bezieht sich auf ein Zahnrädergetriebe nach dem Oberbegriff von Patentanspruch 1.The invention relates to a gear transmission according to the Preamble of claim 1.

Ein Zahnrädergetriebe dieser Art wird in der Beschreibungsein­ leitung der DE-PS 31 18 585 als bekannt angegeben, wonach zur Entfernung fester Fremdkörper, vor allem auch von Metallparti­ keln, aus dem im Getriebegehäuse herumgewirbelten Schmieröl innerhalb des Getriebegehäuses eine Auffangwanne vorgesehen sei, welche durch eine senkrechte Trennwand in zwei Hälften unterteilt sei und einen oberen Ablaufkanal aufweise, so daß das an der Innenfläche des Getriebegehäuses herablaufende und in die Auffangwanne gelangende Schmieröl erst nach unten und dann wieder nach oben strömen müsse, bevor es die Auffangwanne durch den Ablaufkanal hindurch verlassen könne, um das Absetzen von festen Fremdkörpern bzw. Metallpartikeln am Boden der Auf­ fangwanne zu ermöglichen, was noch durch einen in der Nähe des Bodens vorgesehenen Magneten unterstützt werden könne. Es wird also ein Verfahren beschrieben, bei welchem die Fremdpartikel auf dem Wege einer Sedimentation im Ölfangbehälter abgeschieden werden.A gear transmission of this type is in the description line of DE-PS 31 18 585 specified as known, after which for Removal of solid foreign bodies, especially metal parts from the lubricating oil whirled around in the gearbox a drip pan is provided within the gearbox be, which by a vertical partition in half be divided and have an upper drain channel, so that the descending on the inner surface of the gear housing and lubricating oil entering the sump first and then have to flow back up before it catches the pan through the drainage channel to settle of solid foreign bodies or metal particles on the bottom of the door catch pan to allow what is left by a near the Provided magnets can be supported. It will So described a method in which the foreign particles separated by sedimentation in the oil trap will.

Um eine hinreichende Sedimentation zu erreichen, benötigt man erhebliche Verweilzeiten des Öles im Sedimentationsbecken sowie eine beträchtliche Beckentiefe, um ein Wiederaufwirbeln des Sedimentes zu vermeiden.To achieve adequate sedimentation, you need considerable dwell times of the oil in the sedimentation basin as well a considerable depth of the pelvis in order to revive the Avoid sediment.

Die der Erfindung zugrundeliegende Aufgabe besteht im wesent­ lichen darin, eine schnelle Reinigung des Öles bei relativ ge­ ringem Bauvolumen des Ölauffangbehälters zu erreichen.The object underlying the invention is essentially Lichen in a quick cleaning of the oil at relatively low to achieve a small volume of the oil collecting container.

Die erläuterte Aufgabe ist gemäß der Erfindung mit den kenn­ zeichnenden Merkmalen von Patentanspruch 1 in vorteilhafter Weise gelöst.The explained task is according to the invention with the kenn drawing features of claim 1 in advantageous Way solved.

Bei dem Zahnrädergetriebe nach der Erfindung arbeitet der Öl­ auffangbehälter mit einem Schwerkraftfilter, bei dem die Befüllungsöffnung sehr klein ist und nennenswerte Strömungsge­ schwindigkeiten nicht auftreten. Dadurch bildet sich mit der Zeit ein Filterkuchen, welcher immer feinere Teilchen abschei­ det. Dieses Abscheideverfahren trägt somit etwa der Ver­ schleißpartikelgröße des Abriebs über der Lebensdauer des Ge­ triebes Rechnung.In the gear transmission according to the invention, the oil works collecting container with a gravity filter, in which the Filling opening is very small and noteworthy flow speed does not occur. This forms with the Time a filter cake, which separates ever finer particles det. This separation process thus bears the Ver wear particle size of the abrasion over the life of the Ge drive bill.

Bei dem Zahnrädergetriebe nach der Erfindung tritt ein vor­ teilhafter Nebeneffekt insofern auf, als auch bei starken Er­ schütterungen - beispielsweise bei einem Kaltstart - und hoher Ölviskosität keine Partikel aufgewirbelt werden - weil das Filter leertropft - und somit auch nicht wieder in den Öl­ kreislauf gelangen können, wie das bei Sedimentationsabschei­ dern oftmals der Fall ist.A occurs in the gear transmission according to the invention partial side effect in that, as well as with strong Er vibrations - for example during a cold start - and high Oil viscosity no particles are whirled up - because that Filter drips - and therefore not back into the oil circulation, like that with sedimentation which is often the case.

Die Erfindung beruht wesentlich auf dem Gedanken, daß die Ver­ schleißpartikel nicht unbedingt nach den ersten Ölumläufen weggefiltert sein müssen, sondern daß eine allmähliche stati­ stische Häufigkeitsminderung ausreicht, weil nicht jedes Par­ tikel beim Umlauf zwischen kraftschlüssige Metallflächen gerät.The invention is essentially based on the idea that the Ver wear particles not necessarily after the first oil circulation must be filtered out, but that a gradual stati reduction in frequency is sufficient because not every par particle when circulating between non-positive metal surfaces.

Andererseits ist die durch die Erfindung ermöglichte sehr feine Filterung - welche durch Sedimentation nicht erreichbar ist - vorteilhaft, weil Zahnrädergetriebe im Mischreibungsbereich arbeiten und daher sehr enge Spalte entstehen, in denen größere Teilchen progressiven Verschleiß verursachen, während unterhalb einer bestimmten Teilchengröße kaum noch Verschleiß auftritt.On the other hand, the very fine one made possible by the invention Filtering - which cannot be achieved by sedimentation - advantageous because gear drives in the mixed friction range  work and therefore very narrow gaps arise in which larger ones Particles cause progressive wear while below a certain particle size hardly any wear occurs.

Die Unteransprüche haben vorteilhafte Ausgestaltungen der Er­ findung zum Gegenstand.The subclaims have advantageous embodiments of the he finding the object.
