Abstract

A high-performance sliding bearing which is self-lubricating without incurring additional outlay and retains its high loading capacity, comprising an outer ring, an inner ring and sealing elements attached on one or both sides to the said outer ring, which sealing elements are attached by means of sealing strips to the end faces of the inner ring and to the end face of the outer ring to form a cavity which can be filled with lubricant and is connected to a lubrication gap. <IMAGE>

Description

Lagereinheit Storage unit

Drehende Teile, wie z.B. Wellen von Maschinen aller Art, laufen größtenteils auf Wälz- oder Gleitlagern. Trotz starker Ausbreiwng der Wälzlager aufgrund ihrer vielen guten Eigenschaften, hat das Gleitlager doch in solchen Anwendungsfällen, in denen seine Eigenschaften gefragt sind, seinen Platz behauptet. Diese Eigenschaften bestehen in kleinen, radialen und somit kostengünstigen Abmessungen, in leisem und mechanisch ruhigem Lauf, in hoher Belastbarkeit bei Stößen des laufenden und stehenden Lagers und in zunehmender Belastbarkeit bei größer werdender Lagergeschwindigkeit. Während bei einem Wälzlager eine betriebsbereite, oft schon mit Schmiermittel versehene Lagerungseinheit vorliegt, die nur noch auf eine entsprechend gepaßte Welle und in eine entsprechende Gehäusepartie eingebracht werden muß, benötigt das Gleitlager oft eine zusätzliche Schmiereinrichtung in Form eines Schmierringes, einer Ölpumpe o.ä., die die Vorteile eines Gleitlagers schmälern. Es sind Gleitlager bekannt, die mit Gleitmitteln versehen bzw. gefüllt sind, z.B. mit Sinterstoffen, die jedoch aufgrund dieser Schmierung nicht hoch belastet arbeiten können.Rotating parts, such as the shafts of all kinds of machines, run for the most part on roller or plain bearings. Despite the strong expansion of the rolling bearings due to their many good properties, as the plain bearing has in such applications in which its properties are in demand, asserts its place. These properties exist in small, radial and thus inexpensive dimensions, in quiet and Mechanically smooth running, in high resilience with impacts of the running and standing Storage and in increasing load capacity with increasing storage speed. In the case of a rolling bearing, one that is ready for operation and often already provided with lubricant There is a storage unit that only needs to be fitted with a correspondingly fitted shaft and must be introduced into a corresponding housing section, requires the plain bearing often an additional lubricating device in the form of a lubricating ring, an oil pump or similar that reduce the advantages of a plain bearing. There are known sliding bearings which are provided or filled with lubricants, e.g. with sintered materials, but which due to this lubrication, cannot work under high loads.

Aufgabe der Erfindung ist die Behebung des Aufwandes der zusätzlichen Einrichtungen bei Wahrung einer guten, hochbelastbaren Lagerfunktion, wobei die Lösung in einer Lagereinheit besteht, ihrerseits bestehend aus einem Außenring 1, einem Innenring 2 sowie aus ein- oder beidseitig am Außenring 1 angebrachten Dichtelementen 3, die mit ihren Dichtleisten 3' an den Stirnflächen 2' des Innenringes 2 dichtend schleifen und an der Stirnfläche 1' des Außenringes 1 unter Bildung eines mit Schmiermittel füllbaren Hohl raumes 4 angebracht sind, der mit einem Schmierspalt 5 in Verbindung steht, derart, daß dieser seitlich mit Schmiermittel versorgbar ist. Dabei kann sowohl der Außenring 1 und/oder der Innenring 2 mit einem Einstellsteg 6, 7 versehen werden, die im Gehäuse 8 und/oder auf der Welle 9 eine Anpassung des Dichtspaltes begünstigen. Dieses Lager kann mit einer Nachschmierbohrung 10 versehen sein, welche die erstmalige oder Folgefüllung mit Schmiermittel erlaubt, eventuell mit beiderseits angeordneten Dichtringen 19.The object of the invention is to eliminate the expense of the additional Facilities while maintaining a good, heavy-duty storage function, whereby the Solution consists of a bearing unit, in turn consisting of an outer ring 1, an inner ring 2 and sealing elements attached to one or both sides of the outer ring 1 3, which seal with their sealing strips 3 'on the end faces 2' of the inner ring 2 grind and on the end face 1 'of the outer ring 1 to form a lubricant fillable cavity 4 are attached, which is connected to a lubricating gap 5 stands in such a way that it can be supplied with lubricant from the side. Here can both the outer ring 1 and / or the inner ring 2 are provided with an adjusting web 6, 7 that in the housing 8 and / or on the shaft 9 an adaptation of the sealing gap favor. This bearing can be provided with a relubrication hole 10, which initial or subsequent filling with lubricant is permitted, possibly with both sides arranged sealing rings 19.

Gemäß Fig. 2 ist es möglich, das Gleitlager auch direkt ohne Innenring 2 auf der Welle 9 anzubringen. Dabei ist die Neuheit als Einheit des mit dem Außenring 1 verbundenen Dichtelementes 3 beibehalten, die hier direkt auf der Welle 9 dichtend angeordnet sind.According to FIG. 2, it is possible to use the plain bearing directly without an inner ring 2 to be attached to the shaft 9. The novelty is as a unit with the outer ring 1 connected sealing element 3 retained, the sealing here directly on the shaft 9 are arranged.

In weiterer Ausgestaltung dieses Gleitlagers werden gomäß Fig.3 die Außen- und Innenringe so ausgebildet, daß ein gesteuerter Schmiermittelfluß bewirkt wird. Auf diese Weise wird die Kühlung intensiviert, das Schmiermittel geschont, sein Volumen vergrößert und der Schmierspalt mit Schmiermittel niedrigerer Temperatur versorgt, d.h. höheres Tragvermögen und somit größere Sicherheit herbeigeführt.In a further embodiment of this plain bearing are gomäß Fig.3 the Outer and inner rings designed so that a controlled flow of lubricant effects will. In this way the cooling is intensified, the lubricant is spared, its volume increases and the lubrication gap with lubricant of lower temperature supplied, i.e. higher buoyancy and thus greater safety brought about.

In seiner allgemeinen Ausführung hat dabei der Außenring 1 in Ausführung dieses Gedankens umlaufende Ringnuten 11, 12 und der Innenring 2 zur zusätzlichen Erhöhung der Wirkung umlaufende Ringnuten 13, 14. Die Ringnuten 11,12 stehen über Kanäle 15, die Ringnuten 13, 14 über Kanäle 16 in Verbindung. Zur Einleitung einer Zirkulation wird mit den in der Ringnut 13 angeordneten Pumpenschaufeln 17 ein Wirbel angefacht, der mit in der Ringnut 11 des Außenringes 1 angeordneten Leitschaufeln 18 abgebremst wird und somit die Schmiermittelzirkulation von der Ringnut 13 durch den Hohlraum 4 über die Rinynut 11 durch die Kctrd'ie 15 in die Ringnut 12 wieder über den Hohlraum 4, die Ringnut 14 über die Kanäle 16 zurück in den Raum 13 bwirkt. Dabei wird auch in einem Bypass der Schmierspalt 5 zusätzlich beschickt.In its general design, the outer ring 1 is in design this idea circumferential grooves 11, 12 and the inner ring 2 for additional Increasing the effect of circumferential annular grooves 13, 14. The annular grooves 11, 12 protrude Channels 15, the annular grooves 13, 14 via channels 16 in connection. To initiate a Circulation becomes a vortex with the pump blades 17 arranged in the annular groove 13 fanned, the with arranged in the annular groove 11 of the outer ring 1 guide vanes 18 is braked and thus the lubricant circulation from the annular groove 13 through the cavity 4 via the Rinynut 11 through the Kctrd'ie 15 in the annular groove 12 again acts via the cavity 4, the annular groove 14 via the channels 16 back into the space 13. The lubrication gap 5 is additionally charged in a bypass.

Zur erhöhten Wirkung dieser Zirkulation können gemäß Fig. 4 die Schaufeln 17, 18 nach strömungsgünstigen Kriterien ausgebildet werden, z.B. gekrümmt oder auch über die Stirnflächen 2' des Innenringes 2 und die Stirnfläche 1' des Außenringes 1 axial und radtal vorgezogen werden.According to FIG. 4, the blades can be used to increase the effect of this circulation 17, 18 are designed according to flow-favorable criteria, e.g. curved or also over the end faces 2 'of the inner ring 2 and the end face 1' of the outer ring 1 axially and radially are preferred.
