Description

  

  Einrichtung zur Schmierung von Wälzlagern.    Das Verwendungsgebiet der Wälzlager  ist durch die mit zunehmender Drehzahl  stark abnehmende Tragfähigkeit einge  schränkt. Als Hauptgrund hierfür wurde die  namentlich bei grösseren Drehzahlen quanti  tativ unrichtige Schmierung der rollenden  und gleitenden Lagerteile gefunden.  



  Der Schmiermittelbedarf eines Lagers ist  bekanntlich direkt proportional dem Lei  stungsverluste. Bei einem Wälzlager ist nun  dieser Leistungsverlust und daher der  Schmiermittelbedarf ungefähr direkt pro  portional der Drehzahl. In der bisherigen  Praxis bekommen die Wälzlager meistens  bei niedrigen Drehzahlen zu viel und bei  hohen zu wenig Schmiermaterial, oder dann  wird die Schmierung derart reichlich ge  macht, dass bei allen Drehzahlen immer zu  viel Schmiermaterial in die Lager eintritt.  Zu reichliche Schmierung ist aber auch sehr  nachteilig, da dann die grossen Mengen des  stets mehr oder weniger zähflüssigen  Schmiermaterials im Betriebe bremsend wir  ken und die Reibungsverluste in den Wälz  lagern vergrössern. Für jede Drehzahl gibt  es daher eine günstigste Schmiermittelmenge,    und zwar ist diese ungefähr direkt propor  tional der Drehzahl.

   Dieser Erkenntnis ge  genüber war es bisher ein grosser Nachteil,  dass die Wahl der in die Wälzlager treten  den Schmiermittelmenge den Lagerbenützern  überlassen werden musste. Die vorliegende  Erfindung betrifft nun eine Einrichtung zur  selbsttätigen Schmierung von Wälzlagern.  



  Gemäss der Erfindung werden     schrau-          benlinienförmige    Nuten an einem oder meh  reren Lagerteilen so angebracht, dass im Be  trieb dadurch eine durch die Abmessungen  und Anzahl der Nuten willkürlich festgelegte  Pumpwirkung erzielt wird, die das Schmier  mittel in axialer Richtung durch das     Wälz-          Lager    fördert.  



  Die Schmiereinrichtung ist nachstehend  unter Benützung der Fig. 1, 2 und 3 als Aus  führungsbeispiele beschrieben.  



  In Fig. 1 sind an dem aus den Haupt  teilen: Innenring 1, Aussenring 2, Rollen 4  und Käfig 3 bestehenden Wälzlager     schrau-          benlinienförmige    Nuten 6 und 9 aussen an  dem Käfig 3 angebracht. Der mit den Nu  ten 6 und 9 versehene Käfig 3 und der  Aussenring 2 bilden nun zusammen eine in      der Technik allgemein bekannte Viskositäts  pumpe, das heisst es wird hei der Relativ  verdrehung bezw. Verschiebung der Ober  flächen des Käfigs 3 und des Aussenringes 2  infolge der Nuten 6 und 9 ein Druck auf  das Schmiermittel ausgeübt, der es dann in  axialer Richtung durch das Wälzlager presst  und dieses entsprechend dem Zweck der Er  findung auf diese Art schmiert.  



  Für die Erreichung der Pumpwirkung  ist es gleichgültig, ob der Aussenring 2 oder  der Käfig 3 oder sogar der Innenring 1, wie  in der Fig. 1 strichpunktiert eingezeichnet  ist, und auch ob einer oder mehrere Lager  teile gleichzeitig die charakteristischen Nuten  aufweisen. Der Windungssinn der Nuten  dieser Teile kann gleich oder verschieden  sein. Die Nuten eines einzelnen dieser Lager  teile sind ebenfalls entweder wie die Nuten  6 und 9 der Fig. 2 gleichsinnig oder zum  Beispiel, wie die Nuten 5 und 6 der Fig. 3  ungleichsinnig gewunden. Die Anordnung  gleichsinniger Nuten nach Fig. 2 erzeugt bei  jeder Drehrichtung eine Schmiermittelzirku  lation durch das Wälzlager und staut zum  Beispiel das Öl auf der einen Lagerseite.  Um diese Stauung wieder auszugleichen,  ist, wie zum Beispiel in der Fig. 1, im La  gergehäuse 7 eine Umlaufleitung 3 vorhan  den.

   Je nach Erfordernis wird, wie zum  Beispiel in Fig. 1, ein Sieb 10 in den Öl  strom eingebaut, um das Öl im Betrieb  dauernd zu reinigen.



  Device for the lubrication of roller bearings. The area of application of the rolling bearings is limited by the load capacity, which decreases sharply with increasing speed. The main reason found was the quantitatively incorrect lubrication of the rolling and sliding bearing parts, especially at higher speeds.



  As is well known, the lubricant requirement of a bearing is directly proportional to the losses. In the case of a roller bearing, this loss of power and therefore the lubricant requirement is approximately directly proportional to the speed. In previous practice, the roller bearings usually received too much lubricant at low speeds and too little lubricant at high speeds, or the lubrication is then made so abundantly that too much lubricant material always enters the bearings at all speeds. Too abundant lubrication is also very disadvantageous, since then the large amounts of the more or less viscous lubricating material in the company brake we ken and increase the friction losses in the rollers. For each speed there is therefore the most favorable amount of lubricant, and this is approximately directly proportional to the speed.

   Compared to this knowledge, it was previously a major disadvantage that the choice of the amount of lubricant used in the rolling bearings had to be left to the bearing users. The present invention now relates to a device for the automatic lubrication of roller bearings.



  According to the invention, helical grooves are attached to one or more bearing parts in such a way that, during operation, a pumping effect determined by the dimensions and number of grooves is achieved, which pumps the lubricant in the axial direction through the roller bearing.



  The lubrication device is described below using FIGS. 1, 2 and 3 as exemplary embodiments from.



  In FIG. 1, the roller bearings consisting of the main parts: inner ring 1, outer ring 2, rollers 4 and cage 3 are attached to the outside of the cage 3 in the form of helical grooves 6 and 9. The cage 3 provided with the grooves 6 and 9 and the outer ring 2 now together form a viscosity pump generally known in the art, that is to say it is called the relative rotation. Shifting the upper surfaces of the cage 3 and the outer ring 2 as a result of the grooves 6 and 9 exerted pressure on the lubricant, which then presses it in the axial direction through the roller bearing and lubricates it in this way according to the purpose of the invention.



  To achieve the pumping effect, it does not matter whether the outer ring 2 or the cage 3 or even the inner ring 1, as shown in phantom in FIG. 1, and whether one or more bearing parts simultaneously have the characteristic grooves. The direction of winding of the grooves in these parts can be the same or different. The grooves of a single one of these bearing parts are also wound either in the same direction as the grooves 6 and 9 of FIG. 2 or, for example, as the grooves 5 and 6 of FIG. 3 in the same direction. The arrangement of grooves in the same direction as shown in FIG. 2 generates a lubricant circulation through the roller bearing in each direction of rotation and, for example, accumulates the oil on one side of the bearing. In order to compensate for this stagnation again, as for example in FIG. 1, a circulation line 3 is in the La gergehäuse 7 IN ANY of the.

   Depending on the requirement, as for example in Fig. 1, a sieve 10 is built into the oil stream in order to continuously clean the oil during operation.
