Abstract

The distributor supplies the lubricating grease from outside the central axis of rotation of the bearing. The bearing may be for the wheel of a tracked vehicle motor. The grease is distributed over the bearing by a disc with outlet holes. The outlet holes (11) in the disc (6) increase in size in passing from the grease inlet hole (5') to a point on the diametrically opposite side of the disc. The area of the outlet holes on the diametrically opposite side of the disc to the inlet hole is 1.1 or 10 times the area of the outlet holes immediately adjacent to the inlet hole. The new grease forces the old grease out of the bearing completely and thereby considerably reduces maintenance work.

Description

Schmierfett-VerteileinrichtungLubricating grease distribution device

Die Erfindung betrifft eine Schmierfett-Verteileinrichtung an rotationssymmetrischen Schmierstellen wie an Fahrmotorlagern von Schienenfahrzeugen, deren vollständiger Schmierfett-Austausch bei Stillstand erfolgt und bei denen die Schmierfett-Zuführung außerhalb der Rotationsmittelachse angeordnet ist, wobei der Schmierstoff mittels einer mit Austrittsöffnungen versehenen Verteilscheibe dem Lager zugeführt wird.The invention relates to a lubricating grease distribution device on rotationally symmetrical Lubrication points such as on traction motor bearings of rail vehicles, their more complete Lubricating grease is exchanged during standstill and when the lubricating grease is being supplied is arranged outside the rotation center axis, the lubricant by means of a distributor disc provided with outlet openings is fed to the warehouse.

Derartige Verteilscheiben sind z. B. aus der Broschüre "Schmierung von Wälzlagern", Seite 14, Fig. 12, Publ.-Nr.Such distribution disks are z. B. from the brochure "Lubrication of rolling bearings ", page 14, Fig. 12, Publ.

Bei besonderen Anwendungsfällen z. B. bei elektrischen Fahrmotoren für E-Loks ergeben sich besondere Bedingungen, bei denen die herkömmlichen Methoden nicht mehr ausreichen. Die Forderung nach immer längeren Laufzeiten bei Elektrolokomotiven ohne zwischenzeitliche Nachschmierung läßt sich nur dann erfüllen, wenn an Stelle der üblichen Nachschmierung ein Fettwechsel durchgeführt wird. Dazu war es bisher erforderlich, entweder die Gehäusedeckel abzuschrauben, das tager auszuwaschen und neu zu fetten oder erhebliche Fettmengen in das Lager einzupressen, wobei das Lager gedreht werden mußte, damit ein vollständiger Fettaustausch gewährleistet war. Sowohl das Lagerauswaschen als auch das Nachschmieren bei drehender Lagerung sind aufwendige Wartungsarbeiten, da die Loks dazu in die Betriebswerke gefahren werden müssen.For special applications such. B. in electric traction motors for electric locomotives there are special conditions where the conventional methods no longer sufficient. The demand for ever longer running times for electric locomotives without intermediate relubrication can only be met if in place a grease change is carried out after the usual relubrication. That’s what it was before required to either unscrew the housing cover, wash out the tager and to re-grease or to press considerable amounts of grease into the bearing, whereby the bearing had to be turned so that a complete exchange of grease was guaranteed. As well as Washing out the bearings and relubrication when the bearings are rotating are time-consuming Maintenance work, as the locomotives have to be driven to the depot for this.

Es ist deshalb Aufgabe der Erfindung, mit einfachen Mitteln eine Schmierfett-Verteileinrichtung aufzuzeigen, die einen nahezu vollständigen Fettwechsel im Stillstand der Lagerung bei sparsamem Schmierfett-Verbrauch ermöglicht und damit weit längere Nachschmierfristen als bei herkömmlicher Nachschmierung zuläßt.It is therefore the object of the invention to provide a lubricating grease distribution device with simple means to show that an almost complete change of grease when storage is at a standstill with economical grease consumption and thus much longer relubrication periods than with conventional relubrication.

Die Lösung dieser Aufgabe ist aus Anspruch 1 ersichtlich.The solution to this problem can be seen from claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung enthalten die Ansprüche 2 bis 5.The claims contain further advantageous refinements of the invention 2 to 5.

Die Erfindung soll an vorteilhaften Ausführungsbeispielen dargestellt werden.The invention is to be illustrated using advantageous exemplary embodiments will.

Es zeigt: Fig. 1 einen Querschnitt durch eine Wälzlagerung mit Schmierfett-Verteilscheibe Fig. 2 eine Schmierfett-Verteilscheibe in Verbindung mit einem Gehäusedeckel in Vorderansicht und im Schnitt.It shows: FIG. 1 a cross section through a roller bearing with a lubricating grease distribution disk FIG. 2 shows a lubricating grease distribution disk in connection with a housing cover in FIG Front view and in section.

In Fig. 1 ist die Lagerung eines elektrischen Fahrmotors für E-Loks dargestellt. Die Welle 1 ist über ein Wälzlager 2 im Gehäuse 3 gelagert. Neben dem Wälzlager 2 ist eine Schmierfett-Verteilscheibe 6 angeordnet, die über ein Zuführrohr 5 und eine Zuführbohrung 5' mit Schmierfett versorgt wird. Die Schmierfett-Verteilscheibe 6 ist dabei neben einem Gehäusedeckel 4 angeordnet, der einen umlaufenden Ringraum 10 aufweist. Auf der anderen Seite des Wälzlagers 2 ist eine Reglerscheibe 7 angeordnet, die das vom Frischfett verdrängte Altfett aus dem Lager 2 in den von Gehäuse 3 und Gehäusescheibe 8 gebildeten Raum ableitet. Auf der Welle 1 ist noch ein Labyrinthring 9 angeordnet, der mit dem Gehäusedeckel 4 zusammenwirkt.In Fig. 1 is the storage of an electric traction motor for electric locomotives shown. The shaft 1 is mounted in the housing 3 via a roller bearing 2. Next to the Rolling bearing 2 is a lubricating grease distribution disk 6, which is via a feed pipe 5 and a feed hole 5 'is supplied with lubricating grease. The grease distribution disc 6 is arranged next to a housing cover 4, which has a circumferential annular space 10 has. On the other side of the roller bearing 2, a regulator disc 7 is arranged, the old fat displaced by the fresh fat from the bearing 2 into the housing 3 and Housing disc 8 derives space formed. There is still a labyrinth ring on shaft 1 9, which cooperates with the housing cover 4.

Wie aus Fig. 2 ersichtlich ist, wirken die Fettverteilscheibe 6 und der Gehäusedeckel 4 zusammen und bilden einen umlaufenden Ringraum 10, der zum Wälzlager 2 hin Austrittsöffnungen 11 aufweist. Bei den dargestellten Ausführungsbeispiel sind sechs Austrittsöffnungen 11 gleichmäßig über den Umfang verteilt angeordnet, wobei der Austrittsquerschnitt der Austrittsöffnungen an der Stelle, die der Schmierfett-Zuführungsbohrung 5' gegenüberliegt, das 2,9 bis 6,25-fache beträgt als der Austrittsquerschnitt der Austrittsöffnungen im Bereich der Zuführbohrung 5'. Bei diesem Beispiel betragen bei einem Teilkreisdurchmesser von 140 mm die Durchmesser der Austrittsöffnungen 10 im oberen Bereich 1 mm, im mittleren Bereich 1,5 mm und im unteren Bereich 2,5 mm. Mit dieser Ausführung ließ sich bei stillstehender Lagerung ein nahezu vollständiger Fettwechsel erreichen.As can be seen from Fig. 2, the fat distribution disk 6 and act the housing cover 4 together and form a circumferential Annulus 10, which has outlet openings 11 towards the roller bearing 2. In the illustrated Embodiment are six outlet openings 11 evenly over the circumference arranged distributed, the exit cross-section of the exit openings on the Position opposite the grease supply hole 5 ', 2.9 to 6.25 times is than the exit cross-section of the exit openings in the area of the feed bore 5 '. In this example, with a pitch circle diameter of 140 mm, the diameters are of the outlet openings 10 in the upper area 1 mm, in the middle area 1.5 mm and 2.5 mm in the lower area. This version could be used with stationary storage achieve an almost complete change of fat.

Es ist auch möglich, einen umlaufenden, sich bis zu der der Schmierfett-Zuführungsbohrung gegenüberliegenden Stelle erweiternden Spalt vorzusehen.It is also possible to run a circumferential one up to that of the grease feed hole provide a widening gap on the opposite side.
