Abstract
Description
Die vorliegende Erfindung betrifft eine Schmiervorrichtung für eine Welle-Nabe-Verbindung gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a lubricating device for a shaft-hub connection according to the preamble of claim 1
In der Automobiltechnik werden Wellen-Naben Verbindungen sehr oft eingesetzt, um Bauteile, beispielsweise Zahnräder, mit einer Welle zu verbinden.In automotive technology, shaft-hub connections are used very often, To connect components, such as gears, with a shaft.
Hierbei ist eine ausreichende Schmierung von Welle-Nabe-Verbindungen, insbesondere von Welle-Nabe-Verbindungen mit einer Steckverzahnung zur formschlüssigen Verbindung zwischen Welle und Nabe, besonders wichtig, um diese vor Passungsrost zu schützen und um damit einen Flankenverschleiß zu verhindern. Eine starke Passungsrostbildung kann in nachteiliger Weise zum Ausfall der Steckverzahnung führen. Des weiteren werden durch starke Passungsrostbildung viele abrasive Schmutzpartikel in das betroffene System eingebracht.in this connection is adequate lubrication of shaft-hub connections, in particular of shaft-hub connections with a spline for positive connection between shaft and hub, especially important to these against fretting to protect and to prevent flank wear. A strong Passungsrostbildung can disadvantageously to the failure of the spline to lead. Furthermore, by strong fretting corrosion many abrasive Dirt particles introduced into the affected system.
Schmiervorrichtungen
für Welle-Nabe-Verbindungen
sind nach dem Stand der Technik derart ausgeführt, dass sie Bohrungen für die Ölversorgung aufweisen,
welche in nachteiliger Weise in einer Schwächung der Konstruktion resultieren.
Eine gattungsgemäße Schmiervorrichtung
ist beispielsweise aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schmiervorrichtung für eine Welle-Nabe-Verbindung anzugeben, welche die Bildung von Passungsrost und einen daraus resultierenden Flankenverschleiß verhindert. Zudem soll die erfindungsgemäße Schmiervorrichtung keine schwächenden Bohrungen für die Ölversorgung zum Schutz vor Passungsrost erfordern und eine gleichmäßige Beölung der Verbindung gewährleisten.Of the present invention is based on the object, a lubricating device for one Shaft-hub connection indicate the formation of fretting corrosion and prevents resulting flank wear. In addition, the should lubricating device according to the invention no debilitating Holes for the oil supply To protect against fretting and require a uniform lubrication of Ensure connection.
Diese Aufgabe wird durch eine Schmiervorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These Task is performed by a lubricating device with the characteristics of Patent claim 1 solved. Further embodiments of the invention and Advantages are apparent from the dependent claims.
Demnach wird eine Schmiervorrichtung für eine Welle-Nabe-Verbindung mit einem benachbarten schmieröldurchströmten Lager, welches vorzugsweise als Wälzlager ausgebildet ist, vorgeschlagen, bei der ein Teil der das Lager durchströmenden Schmierflüssigkeit abgezweigt wird und axial in das Mitnahmeprofil bzw. in die Steckverzahnung der Welle-Nabe-Verbindung geleitet wird.Therefore is a lubricating device for a Shaft-hub connection with an adjacent lubricating oil flow bearing, which preferably as a rolling bearing is formed, proposed in which a part of the bearing flowing through the lubricating fluid is branched off and axially into the driving profile or in the spline the shaft-hub connection is routed.
Das Lager dient der Lagerung der Welle oder der Nabe in ein anderes Bauteil, vorzugsweise im Gehäuse, und kann vorzugsweise als Wälzlager ausgebildet sein und axial betrachtet neben oder auch radial betrachtet oberhalb der Steckverzahnung der Welle-Nabe-Verbindung angeordnet sein.The Bearing is used to store the shaft or hub in another Component, preferably in the housing, and may preferably be used as rolling bearings be formed and viewed axially next to or viewed radially arranged above the splines of the shaft-hub connection be.
Gemäß einer nicht unter den Schutzumfang fallenden Ausführungsform umfasst die Schmiervorrichtung eine Stauscheibe, die benachbart zur Steckverzahnung, beispielsweise axial betrachtet zwischen dem Lager und der Steckverzahnung, angeordnet ist und einen Ölstauraum zum Aufstauen von Schmieröl bildet. Hierbei weist die Scheibe einen düsenförmigen Querschnitt auf, so dass das aufgestaute Schmieröl axial in das Mitnahmeprofil der Steckverzahnung geleitet wird. Der Querschnitt kann auch durch die Scheibe in Verbindung mit der Welle oder der Nabe gebildet werden.According to one The embodiment not covered by the scope of protection includes the lubricating device a baffle plate adjacent to the spline, for example viewed axially between the bearing and the spline, arranged is and an oil storage for damming up lubricating oil forms. Here, the disc has a nozzle-shaped cross-section, so that the pent-up lubricating oil is passed axially into the driving profile of the spline. Of the Cross section can also be through the disc in conjunction with the shaft or the hub can be formed.
Hierbei
wird ein vorhandener Ölstrom
im Stauraum in zwei Ölströme aufgeteilt:
ein
erster Ölstrom
fließt
zurück
in Richtung des Lagers ab und der andere Ölstrom wird axial in die Steckverzahnung
gedrückt.
Durch eine im Betrieb vorhandene Axialbewegung der Verzahnung im
Rahmen des Axialspiels wird diese Pumpwirkung verstärkt.Here, an existing oil flow in the storage space is divided into two oil streams:
a first oil flow flows back towards the bearing and the other oil flow is forced axially into the spline. By existing in operation axial movement of the teeth in the context of the axial play this pumping action is enhanced.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Schmiervorrichtung eine Schmierölzuführung aufweist, die durch eine Schmierölzuführung eines Lagerinnenringes gebildet wird, der im Bereich seines Innendurchmessers an der der Welle bzw. Nabe zugewandten Seite mit der Welle bzw. Nabe einen Ölstauraum zum Aufstauen des Schmieröls bildet. Der Lagerinnenring bildet hierbei zusammen mit der Welle bzw. Nabe einen düsenförmigen Austrittsquerschnitt für das im Ölstauraum aufgestaute Schmieröl zu dessen Zuleitung axial in die Steckverzahnung. Gemäß der Erfindung kann der düsenförmige Austrittsquerschnitt am Lagerinnenring oder am Außendurchmesser der Welle bzw. Nabe ausgebildet sein.According to one preferred embodiment of Invention is provided that the lubricating device has a lubricating oil supply, by a lubricating oil supply a Inner bearing ring is formed, which is in the range of its inner diameter at the shaft or hub side facing the shaft or Hub an oil storage for damming the lubricating oil forms. The bearing inner ring forms here together with the shaft or hub has a nozzle-shaped outlet cross-section for the in the oil storage room pent-up lubricating oil to the supply line axially into the spline. According to the invention can the nozzle-shaped outlet cross-section on the bearing inner ring or on the outer diameter be formed of the shaft or hub.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es zeigen:The The invention will be explained in more detail below by way of example with reference to the attached figures. Show it:
Eine erfindungsgemäße Schmiervorrichtung ist derart ausgebildet, dass ein Teil der das benachbarte Lager durchströmenden Schmierflüssigkeit abzweigbar und axial in das Mitnahmeprofil bzw. in die Steckverzahnung der Welle-Nabe-Verbindung leitbar ist, wie im Folgenden erläutert wird.A Lubricating device according to the invention designed such that a part of the lubricant flowing through the adjacent bearing branched off and axially in the driving profile or in the spline the shaft-hub connection is conductive, as will be explained below.
