Abstract

The worm-type gearbox has a grease-lubricated rotary component. A hard felt ring (4) rotating in a bearing is impregnated with high-pressure grease, and engages with the rotary component (3). The filtering can be rigidly mounted on a self-lubricating bush (5), rotating on a gearbox shaft (6), and it can be arranged to engaged with the wormwheel. The design requires little maintenance, nor are elaborate seals necessary to prevent leakage.

Description

Getriebe, insbesondere SchneckengetriebeGears, in particular worm gears

Die Erfindung bezieht sich auf ein Getriebe, insbesondere Schneckengetriebe, mit einem umlaufenden Getriebeteil und mit einer diesem zugeordneten Fettschmierung.The invention relates to a gear, in particular worm gear, with a rotating gear part and with a grease lubrication assigned to it.

Schnell laufende Getriebeteile, die unter Umständen hoch beansprucht sind, benötigen eine wirksame Schmierung, um einerseits Reibungsverluste gering zu halten und andererseits den Verschleiß zu vermindern. Hierzu ist es bekannt, die Getriebegehäuse, in denen die schnell laufenden Getriebeteile drehbar gelagert sind, mit Fett oder mit dl zu füllen. Das Getriebegehäuse bildet damit ein Reservoir für das Schmiermittel. Hierzu muß das Getriebegehäuse dicht sein, was im Hinblick auf eine huber längere Zeit erwünschte tartungsfreiheit problematisch ist.Fast-running gear parts that can be highly stressed under certain circumstances require effective lubrication in order to minimize friction losses on the one hand to keep and on the other hand to reduce wear. For this it is known the gear housing, in which the high-speed gear parts are rotatably mounted are to be filled with fat or with dl. The gear housing thus forms a reservoir for the lubricant. For this purpose, the gear housing must be tight, what in view freedom from maintenance, which is desired for a longer period of time, is problematic.

Der Erfindung liegt die Aufgabe zugrunde, ein Getriebe der eingangs genannten Art zu schaffen, bei dem mit einem geringen Aufwand an Betriebsmitteln bei geringen Dichtheitsanforderungen an das Getriebegehäuse weitestgehende Vartungsfreiheit erzielbar ist.The invention is based on the object of a transmission of the initially to create the type mentioned, in which with a low expenditure of resources In the case of low tightness requirements on the gearbox housing, the greatest possible freedom from maintenance is achievable.

Nach der Erfindung wird dies gelöst durch einen in Eingriff mit dem umlaufenden Getriebeteil stehenden, drehbar gelagerten Hartfilzring, der mit Hochdruckfett getränkt ist.According to the invention this is solved by an in engagement with the rotating gear part standing, rotatably mounted hard felt ring, which is coated with high pressure grease is soaked.

Durch Anwendung der Erfindung ist das Schmiermittele'sauf einen vergleichsweise kleinen Raum eines Bauteiles beschränkt, das gemeinsam mit anderen rotierenden Getriebeteilen umläuft. Durch den ständigen Eingriff des Hartfilzringes mit dem zu schmierenden Getriebeteil ist eine effiziente Schmierung dauernd gewährleistet.By applying the invention, the lubricant is comparative to one another limited space of a component that is shared with other rotating gear parts running around. Due to the constant engagement of the hard felt ring with the one to be lubricated Efficient lubrication is guaranteed at all times in the transmission part.

Der Schmiermittelbedarf ist wesentlich geringer, und außerdem brauchen die Getriebegehäuse nicht mehr flüssigkeitsdicht, sondern nur noch staubdicht ausgeführt zu werden.The need for lubricant is much lower, and also need the gear housing is no longer liquid-tight, but only designed to be dust-tight to become.

Bei einer bevorzugten Ausflihrungsform der Erfindung ist der Hartfilzring auf einem selbstschmierenden Gleitlagerring starr befestigt, der auf einer Getriebewelle drehbar gelagert ist. Der Hartfilzring ist bei Schneckengetriebe bevorzugt mit dem Schnecke rad in Eingriff. Es ist aber auch möglich, die Schnecke mit dem Hartfilzring direkt zu koppeln.In a preferred embodiment of the invention, the hard felt ring rigidly mounted on a self-lubricating slide bearing ring, which is mounted on a gear shaft is rotatably mounted. The hard felt ring is preferred with the worm gear Worm gear engaged. But it is also possible to use the hard felt ring for the worm to couple directly.

Anhand der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Ausführungsform beschrieben und die Wirkungsweise erläutert.Based on the drawing is an embodiment of the invention Embodiment described and the mode of operation explained.

Die Figur zeigt in einem Schnitt ein Getriebe, das als Schneckengetriebe ausgebildet ist. Das Getriebe besteht aus einem Gehäuse 1, in dem eine Schnecke 2 drehbar gelagert ist. Mit der Schnecke 2 steht ein Schneckenrad 3 in Eingriff, das ebenfalls drehbar gelagert ist. Mit diesem Schneckenrad 3 steht wiederum ein Hartfilzring 4 in Eingriff, der mit Hochdruckfett getränkt ist. Er ist auf einem selbstschmierenden Gleitlagerring 5 starr befestigt, z. B. geklebt, der seinerseits auf einer Getriebewelle 6 drehbar gelagert ist. Der Hartfilzring 4 gibt die von der Schnecke 2 und dem Schneckenrad 3 benötigte Schmiermittelmenge in fein dosierter Form ab, so daß hierfür keine weiteren Schmiermittelmengen benötigt werden.The figure shows in a section a gear that acts as a worm gear is trained. The gear consists of a housing 1 in which a worm 2 is rotatably mounted. A worm wheel 3 is in engagement with the worm 2, which is also rotatably mounted. This worm wheel 3 is in turn a Hard felt ring 4 in engagement, which is impregnated with high pressure grease. He's on one self-lubricating plain bearing ring 5 rigidly attached, for. B. glued, in turn is rotatably mounted on a gear shaft 6. The hard felt ring 4 is from the worm 2 and the worm wheel 3 required amount of lubricant in finely dosed Form so that no further amounts of lubricant are required for this.

Als Hochdruckfett kommen handelsübliche Schmiermittel in Betracht, wie z. B. das von der Firma Esso unter der Handelsbezeichnung Cazar K 1 H vertriebene Fett.Commercially available lubricants can be used as high-pressure grease, such as B. the one sold by Esso under the trade name Cazar K 1 H Fat.
