Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Schmieren eines Lagers einer Spinn- oder Zwirnspindel, welche einen Spindelschaft, ein fest montiertes Gehäuse und ein ein flüssiges Schmiermittel enthaltendes mit dem Spindelschaft rotierendes Reservoir umfasst, wobei das Lager am Gehäuse befestigt, von diesem umschlossen, und der Spindelschaft durch das Lager rotierbar gehalten ist, und das Schmiermittel sich in einem geschlossenen Kreislauf vom Reservoir zum bezüglich des letzteren erhöht angeordneten Lager und wieder zum rotierenden Reservoir zurück bewegt.The present invention relates to a method for lubricating a bearing of a spinning or twisting spindle, which comprises a spindle shaft, a fixedly mounted housing and a reservoir containing a liquid lubricant and rotating with the spindle shaft, the bearing being fastened to, enclosed by the housing, and the spindle shaft is held rotatably by the bearing, and the lubricant moves in a closed circuit from the reservoir to the bearing, which is arranged higher than the latter, and back again to the rotating reservoir.

Bei bekannten Methoden zum Schmieren von Spindeln wird das Schmiermittel von einem Reservoir nach oben gebracht und daraufhin beim wieder Hinunterfliessen zum Zweck des Schmierens über die zu schmierenden Teile geleitet. Es sind verschiedene Arbeitsweisen bekannt, um das Schmiermittel nach oben zu bringen :In known methods for lubricating spindles, the lubricant is brought up from a reservoir and then passed over the parts to be lubricated when it flows down again for the purpose of lubrication. Various working methods are known to bring the lubricant up:

Gemäss der deutschen Patentschrift Nr. 155 356 steigt es an der Spindel empor, tritt am Ende eines oben angebrachten Lagers aus und gelangt wieder in ein Halslagergehäuse zurück. Gemäss der britischen Patentschrift Nr. 698 141 wird Oel durch Zentrifugalkräfte gegen die Innenwand eines Zylinders geschleudert. Dabei wird dieses nach oben gespritzt und gelangt dabei durch ein oberes und ein unteres Lager.According to German Patent No. 155 356, it rises up the spindle, exits at the end of a bearing attached at the top and comes back into a neck bearing housing. According to British Patent Specification No. 698 141, oil is thrown against the inner wall of a cylinder by centrifugal forces. This is sprayed upwards and passes through an upper and a lower bearing.

In der in der USA-Patentschrift Nr. 2 780 049 gezeigten Einrichtung wird bei Rotation eines Rohres Oel nach oben in einen ringförmigen Raum befördert. Dabei wird ein unteres Lager geölt. Mit zunehmender Rotationsgeschwindigkeit kann Oel bis zum oberen Lager hinauf getragen werden.In the device shown in U.S. Patent No. 2,780,049, oil is conveyed upward into an annular space upon rotation of a tube. A lower bearing is oiled. With increasing rotation speed, oil can be carried up to the upper bearing.

Die deutsche Patentschrift Nr. 455 211 zeigt eine Einrichtung mit einer sich nach oben erweiternden Spindelwelle, bei deren Rotation das Oel sich entlang der Welle nach oben bewegt. Das Zurückbewegen desselben erfolgt längs der Innenwand einer Bohrung.German Patent No. 455 211 shows a device with an upwardly widening spindle shaft, the rotation of which causes the oil to move upwards along the shaft. The same is moved back along the inner wall of a hole.

Die deutschen Patentschriften Nr. 486 106, 538 624 und 654 948 betreffen Einrichtungen, bei denen Oel mittels einer Spiralnut bzw. Schraubennut nach oben gefördert wird.German Patent Nos. 486 106, 538 624 and 654 948 relate to devices in which oil is conveyed upwards by means of a spiral groove or screw groove.

Es ist aus der US-A-1 496 280 und aus der GB-A-27 58 15 auch bekannt, ein mit dem Spindelschaft rotierendes, unterhalb einem zu schmierenden Lager liegendes Oelreservoir vorzusehen. Während des Betriebes der Spindel wird das oel an den Wänden des Oelreservoirs zentrifugiert und dort entweder gesammelt, wie im Fall des britischen Schutzrechtes, oder an den mit einer Fördernut versehenen Spindelschaft angespritzt und somit weiter nach oben gefördert, wie im US-Schutzrecht.It is also known from US-A-1 496 280 and from GB-A-27 58 15 to provide an oil reservoir which rotates with the spindle shaft and lies below a bearing to be lubricated. During the operation of the spindle, the oil is centrifuged on the walls of the oil reservoir and either collected there, as in the case of the British property right, or injected onto the spindle shaft provided with a conveying groove and thus conveyed upward, as in the US property right.

Den bekannten Einrichtungen haftet der Nachteil an, dass bei der grössten Belastung des Antriebs der Spindeln, d. h. bei der höchsten Tourenzahl derselben, oder anders gesagt, während des normalen Wickelvorganges der Spindel, auch die durch das Zuführen des Schmiermittels bedingte Belastung des Spindelantriebs am grössten ist. Das Zusammenfallen dieser maximalen Belastungen ist für den Antrieb nachteilig, da es ein Mehraufwand an Energie bedeutet. Dieser Nachteil soll gemäss der Erfindung vermieden werden und insbesondere soll erreicht werden, dass die Schmierung des Lagers nur kurzzeitig während der Beschleunigungsphase geschieht und dass die Oelförderung und damit auch die forcierte Lagerschmierung sofort unterbrochen wird sobald die Spindel eine bestimmte maximale Rotationsgeschwindigkeit erreicht hat. Die Erfindung ist dadurch gekennzeichnet, dass ein am Gehäuse befestigtes, feststehendes Rohr in das Reservoir eintaucht und den vom letzteren zum Lager führenden Teil des Kreislaufs bildet, dass beim Beginn der Spindelrotation das Schmiermittel im Reservoir vor dem Erreichen seiner maximalen Rotationsgeschwindigkeit gegen eine am eingetauchten Ende des Rohres vorhandene Oeffnung strömt, so dass sich an der Oeffnung ein Staudruck bildet, und dass die Position des Rohres in der Weise gewählt wird, dass sich die Oeffnung beim Erreichen der maximalen Rotationsgeschwindigkeit des Schmiermittels ausserhalb des sich im Reservoir befindlichen, der Fliehkraft ausgesetzten Schmiermittels befindet.The known devices have the disadvantage that with the greatest load on the drive of the spindles, i. H. at the highest number of revolutions, or in other words, during the normal winding process of the spindle, the load on the spindle drive caused by the supply of the lubricant is also greatest. The collapse of these maximum loads is disadvantageous for the drive, since it means an additional expenditure of energy. According to the invention, this disadvantage is to be avoided and, in particular, the aim is to ensure that the bearing is only briefly lubricated during the acceleration phase and that the oil delivery and thus also the forced bearing lubrication are interrupted as soon as the spindle has reached a certain maximum rotational speed. The invention is characterized in that a fixed tube attached to the housing dips into the reservoir and forms the part of the circuit leading from the latter to the bearing, that when the spindle begins to rotate, the lubricant in the reservoir before reaching its maximum rotational speed against one at the immersed end Existing opening of the pipe flows, so that a back pressure forms at the opening, and the position of the pipe is selected in such a way that the opening, when the maximum rotation speed of the lubricant is reached, is outside the lubricant located in the reservoir and subjected to centrifugal force located.

Die Erfindung bezieht sich ausserdem auf eine Spinnoder Zwirnspindel mit einem gemäss dem Verfahren geschmierten, den Spindelschaft rotierbar haltenden Lager und mit einem, mit dem Spindelschaft verbundenen und um eine gemeinsame Achse rotierbaren Reservoir, und ist dadurch gekennzeichnet, dass das Reservoir als ein nach oben offener Behälter ausgebildet ist, dessen Seitenwand mit einem obern Rand versehen ist, welcher sich nach innen bis zum von oben in das Reservoir eintauchenden Gehäuse hin erstreckt und mit diesem einen Dichtungsspalt bildet, und dass der vom Reservoir zum Lager führende Teil des Kreislaufes durch ein vom Reservoir zum Lager führendes Rohr gebildet ist, welches eine oberhalb des Lagers befindliche Ausmündung besitzt.The invention also relates to a spinning or twisting spindle with a bearing lubricated according to the method, which rotatably holds the spindle shaft and with a reservoir connected to the spindle shaft and rotatable about a common axis, and is characterized in that the reservoir is open as an upward opening Container is formed, the side wall is provided with an upper edge which extends inwards to the housing immersed in the reservoir from above and forms a sealing gap with this, and that the part of the circuit leading from the reservoir to the bearing through a from the reservoir tube leading to the bearing is formed, which has an opening located above the bearing.

Damit vermittelt die Erfindung insbesondere den Vorteil einer dem Spinnprozess speziell angepassten Schmiermethode : Beim Beginn des Erstellens einer Wicklung wird das mit dem Reservoir mitrotierende Oel durch das Lager getrieben. Dabei erhält man eine kräftige Schmierung des Lagers. In dem Masse als das Schmiermittel im Reservoir die volle Rotationsgeschwindigkeit erreicht, wird es durch die Zentrifugalkraft gegen die Seitenwand des Reservoirs gedrückt. Das Rohr ist im Reservoir in solchen Abständen von dessen Seitenwand und von dessen Boden positioniert, dass bei dieser vollen Rotationsgeschwindigkeit, d. h. bei normalem Betrieb der Spindel kein Oel mehr gegen das Rohr und damit gegen die am ins Reservoir eingetauchten Ende des Rohres vorhandene Oeffnung fliesst. Damit ergibt es sich, dass während des normalen Betriebes der Spindel kein Schmiermittel mehr in das Rohr gelangt und damit keine Bremswirkung mehr auf das rotierende Reservoir ausgeübt wird. Somit erhält man mit der erfindungsgemässen Spindel beim Beginn des Bewickelns einer Hülse eine sehr kräftige Schmierung, welche bis zur vollen Bewicklung derselben vollauf genügt ; dabei ist während des normalen Wickelvorganges keine Energie für die Zirkulation eines Schmiermittels notwendig.The invention thus conveys in particular the advantage of a lubrication method specially adapted to the spinning process: at the beginning of the creation of a winding, the oil which rotates with the reservoir is driven through the bearing. This gives the bearing vigorous lubrication. As the lubricant in the reservoir reaches full rotational speed, it is pressed against the side wall of the reservoir by centrifugal force. The tube is positioned in the reservoir at such intervals from its side wall and from its bottom that at this full rotational speed, ie during normal operation of the spindle, no more oil flows against the tube and thus against the opening at the end of the tube immersed in the reservoir. In order to the result is that during normal operation of the spindle, no more lubricant gets into the tube and therefore no braking effect is exerted on the rotating reservoir. Thus, with the spindle according to the invention, very strong lubrication is obtained at the beginning of the winding of a sleeve, which is completely sufficient until it is fully wound; no energy is required for the circulation of a lubricant during the normal winding process.

Im folgenden sei die Erfindung anhand eines Ausführungsbeispiels und der Zeichnung näher erläutert. In der letzteren zeigt die

  • Fig. 1 auf ihrer rechten Hälfte eine Seitenansicht und auf ihrer linken Hälfte einen Längsschnitt des unteren Teils einer Spindel, und die
  • Fig. 2 einen Schnitt des unteren Teils des in der Fig. 1 gezeigten Rohres 25 längs einer zur Zeichenebene senkrechten und in der Achse des Rohres 25 liegenden Ebene.
The invention will be explained in more detail below using an exemplary embodiment and the drawing. In the latter shows the
  • Fig. 1 on its right half a side view and on its left half a longitudinal section of the lower part of a spindle, and
  • Fig. 2 shows a section of the lower part of the tube 25 shown in FIG. 1 along a plane perpendicular to the plane of the drawing and lying in the axis of the tube 25.

Die Fig. 1 zeigt einen hohlzylindrischen Spindelschaft 11, welcher um eine Achse 12 rotierbar ist. Ein Reservoir 13 ist fest auf dem Spindelschaft 11 aufgesetzt und mit diesem um die Achse 12 rotierbar. Das Reservoir 13 ist mit einem zum Antreiben vorgesehenen Wirtel 14 versehen. Ausserdem ist ein Klemmring 15 fest auf dem Schaft 11 aufgesetzt und ebenfalls mit diesem rotierbar. Zwischen dem auf dem Spindelschaft 11 aufsitzenden, zylindrischen Teilstück des Klemmringes 15 und einer von diesem getragenen Dichtung 16 ist eine Hülse 17, welche beispielsweise zum Aufwickeln eines Fadens dient, aufsteckbar. Am oberen Ende des Spindelschaftes 11 und in der Zeichnung nicht gezeichnet, befindet sich ein Spindelkopf, welcher ebenfalls zum Halten der aufgesteckten Hülse 17 dient. Die Seitenwand des Reservoirs 13 ist mit einem oberen Rand 18 versehen, welcher sich nach innen erstreckt, im Reservoir 13 befindet sich ein flüssiges Schmiermittel 28, z. B. Oel.1 shows a hollow cylindrical spindle shaft 11 which can be rotated about an axis 12. A reservoir 13 is firmly placed on the spindle shaft 11 and rotatable with it about the axis 12. The reservoir 13 is provided with a vortex 14 provided for driving. In addition, a clamping ring 15 is firmly placed on the shaft 11 and also rotatable therewith. Between the cylindrical portion of the clamping ring 15 seated on the spindle shaft 11 and a seal 16 carried by it, a sleeve 17, which is used, for example, to wind a thread, can be plugged on. At the upper end of the spindle shaft 11 and not shown in the drawing, there is a spindle head which also serves to hold the attached sleeve 17. The side wall of the reservoir 13 is provided with an upper edge 18 which extends inwards. In the reservoir 13 there is a liquid lubricant 28, e.g. B. Oil.

Ein Gehäuse 21 ist, z. B. mittels Schrauben, an einer Spindelbank 22 befestigt. Es ist im wesentlichen von hohlzylindrischer Form und koaxial zur Achse 12 angeordnet. Am Gehäuse 21 sind ein Halslager 23 und ein Fusslager 24 befestigt. Der Spindelschaft liegt an diesen Lagern 23, 24 an und Ist von diesen rotierbar gehalten. Das Gehäuse 21 umschliesst die Lager 23 und 24. Ausserdem bildet es einen sich zwischen den letzteren erstreckenden, umschlossenen Raum. Ein senkrecht angeordnetes Rohr 25 ist fest am Gehäuse 21 befestigt.A housing 21 is, for. B. attached to a spindle bank 22 by means of screws. It is essentially of a hollow cylindrical shape and is arranged coaxially to the axis 12. A neck bearing 23 and a foot bearing 24 are fastened to the housing 21. The spindle shaft bears against these bearings 23, 24 and is held rotatably by these. The housing 21 encloses the bearings 23 and 24. In addition, it forms an enclosed space extending between the latter. A vertically arranged tube 25 is fixedly attached to the housing 21.

An seinem unteren Ende ist das Rohr 25 mit einer oeffnung 26 versehen, welche sich in bezug auf die Rotationsrichtung des Reservoirs 13 auf der vorderen Seite des Rohres 25 befindet.At its lower end, the tube 25 is provided with an opening 26, which is located on the front side of the tube 25 with respect to the direction of rotation of the reservoir 13.

Um im Betrieb einen Faden oder eine Lunte auf eine Hülse 17 aufzuwickeln, wird eine solche, wie in der Fig. 1 gezeigt, auf die Spindel aufgesetzt. Daraufhin werden mittels eines den Wirtel 14 antreibenden Antriebsriemens das Reservoir 13 und der Spindelschaft 11 in Rotation versetzt. Dadurch werden auch der Klemmring 15 und die Hülse 17 mitgenommen. Die Rotation erfolgt in einem solchen Drehsinn, dass sich die in der Zeichnung links der Achse 12 angeordnete Hälfte des Reservoirs 13 vom Betrachter der Zeichnung weg nach hinten bewegt. Da die oeffnung 26 sich auf der gegen den Betrachter hin gerichteten Seite des Rohres 21, d. h. sich in bezug auf die Rotationsbewegung des Reservoirs 13 auf der vorderen Seite des Rohres 25 befindet, so fliesst das Schmiermittel 28 mit zunehmender Rotationsgeschwindigkeit zunehmend stärker gegen die Oeffnung 26. Dabei bildet sich an dieser ein Staudruck, durch welchen Schmiermittel 28 beginnt, im Rohr 25 aufzusteigen, um schliesslich aus der Ausmündung 27 oder der oberen oeffnung des Rohres 25 auszufliessen. Es gelangt von der Ausmündung 27 zum Halslager 23, durchfliesst dieses und fliesst anschliessend längs den Wänden der Teile 11, 21 und 25 nach unten und durch das Fusslager 24 hindurch zurück in das Reservoir 13. Durch das auf diese Weise in einem Kreislauf fliessende Schmiermittel 28 erhält man somit, insbesondere beim Beginn der Hülsenrotation, eine kräftige Schmierung der Lager 23 und 24.In order to wind a thread or a sliver on a sleeve 17 during operation, such as shown in FIG. 1 is placed on the spindle. Then the reservoir 13 and the spindle shaft 11 are set in rotation by means of a drive belt driving the whorl 14. This also entrains the clamping ring 15 and the sleeve 17. The rotation takes place in such a direction of rotation that the half of the reservoir 13 arranged on the left of the axis 12 in the drawing moves away from the viewer of the drawing. Since the opening 26 is located on the side of the tube 21 facing the viewer, i. H. with respect to the rotational movement of the reservoir 13 on the front side of the pipe 25, the lubricant 28 flows with increasing rotation speed against the opening 26. A back pressure, through which lubricant 28 begins, forms in the pipe 25 rise to finally flow out of the mouth 27 or the upper opening of the tube 25. It passes from the mouth 27 to the neck bearing 23, flows through it and then flows down along the walls of the parts 11, 21 and 25 and through the foot bearing 24 back into the reservoir 13 this results in vigorous lubrication of the bearings 23 and 24, especially at the start of the sleeve rotation.

Mit der weiteren Zunahme der Rotationsgeschwindigkeit des Schmiermittels 28 im Reservoir 13 wird dieses als Folge der Fliehkraft immer stärker an die Seitenwand des Reservoirs 13 gedrückt, so dass es dieser Wand entlang in die Höhe steigt. Damit ergibt es sich, dass, nachdem die Spindel ihre bei normalem Betrieb vorhandene Rotationsgeschwindigkeit erreicht hat, das Schmiermittel 28 ungefähr entsprechend der strichlinierten Kurve 31 im Reservoir 13 verteilt ist. Es ist ersichtlich, dass unter diesen Umständen kein Schmiermittel 28 mehr gegen das Rohr 25 und die Oeffnung 26 und damit auch im Rohr 25 kein Schmiermittel mehr in die Höhe fliesst, so dass die Zufuhr von solchem aufhört. Das Schmiermittel 28, welches durch das Rohr 25 den Lagern 23, 24 zugeführt wurde, genügt jedoch vollständig, bis die Hülse voll bewickelt sein wird und wieder ausgewechselt werden muss, oder bis die Spindel sonstwie zum Stillstand kommt. Mit dem Aufhören der Zirkulation des Schmiermittels muss auch keine Antriebsenergie für eine solche Zirkulation mehr erbracht werden. Der Rand 18 verhindert, dass Schmiermittel 28 oben aus dem Reservoir 13 hinaus fliesst. Diese Abdichtung wird noch dadurch verbessert, dass der Rand 18 mit dem Gehäuse 21 einen Dichtungsspalt bildet. Ein solcher verhindert zudem eine Verschmutzung des Schmiermittels 28 durch Faserflug.With the further increase in the rotational speed of the lubricant 28 in the reservoir 13, this is pressed ever more strongly as a result of the centrifugal force against the side wall of the reservoir 13, so that it rises along this wall in height. The result of this is that after the spindle has reached its rotational speed that is present during normal operation, the lubricant 28 is distributed approximately in accordance with the dashed line curve 31 in the reservoir 13. It can be seen that, under these circumstances, no more lubricant 28 flows upwards against the pipe 25 and the opening 26 and therefore also no longer flows in the pipe 25, so that the supply of such ceases. The lubricant 28, which was supplied through the tube 25 to the bearings 23, 24, however, suffices completely until the sleeve is fully wound and has to be replaced again, or until the spindle otherwise comes to a standstill. When the circulation of the lubricant ceases, it is no longer necessary to provide drive energy for such a circulation. The rim 18 prevents lubricant 28 from flowing out of the reservoir 13 at the top. This seal is further improved in that the edge 18 forms a sealing gap with the housing 21. This also prevents contamination of the lubricant 28 by fiber flying.

Gemäss vorliegender Erfindung liegt somit ein Schmiervorgang vor, bei welchem beim Anlaufen automatisch eine kräftige Zufuhr eines Schmiermittels eintritt, welche ohne weiteres für die Zeitdauer des Aufspulens einer Hülse reicht. Die Zufuhr von Schmiermittel 28 ist beim Erreichen des normalen Betriebszustandes beendigt, so dass während des normalen Betriebes für die Zirkulation eines Schmiermittels überhaupt keine Energie mehr beansprucht wird.According to the present invention, there is thus a lubrication process in which a strong supply of lubricant automatically occurs when starting up, which is sufficient for the duration of the winding of a sleeve. The supply of lubricant 28 is terminated when the normal operating state is reached, so that no energy is used at all for the circulation of a lubricant during normal operation.

Im gezeigten Beispiel befindet sich am in das Reservoir 13 eingetauchten Ende des Rohres 25 die Oeffnung 26, an welcher sich ein Staudruck bildet und durch welche das Schmiermittel 28 in das Rohr 25 eintritt. Eine etwas andere Ausführungsform ist in der Fig. 2 dargestellt. In dieser sind wiederum das Reservoir 13, der Wirtel 14, ein Teil des Trägers 21 und das Rohr 25 gezeigt. Gemäss diesem Beispiel umfasst das Rohr 25 an seinem sich im Reservoir 13 befindlichen Ende ein Rohrendstück 34. Das mit dem Reservoir 13 mitrotierende Schmiermittel trifft im wesentlichen von der in Fig. 2 linken Seite her auf die oeffnung 26 auf, erzeugt an dieser einen Staudruck und wird durch diese in das Rohr 25 und in diesem hochgetrieben. Das Rohrendstück 34 ist somit in der Weise abgebogen, dass es sich entgegen der Rotationsrichtung des Reservoirs 13 vom Rohr 25 weg erstreckt. Es vermittelt eine allmählichere Umleitung des Schmiermittels 28 aus seiner horizontalen Bewegung nach oben, als dies beim Vorsehen einer einfachen Oeffnung gemäss Fig. 1 der Fall ist. Damit ist der Strömungswiderstand für das Schmiermittel kleiner als beim Vorliegen von nur einer Oeffnung. Das Einfliessen des Schmiermittels kann noch weiter erleichtert werden, indem die durch das Rohrendstück 34 gebildete Einmündung, wie dies durch die strichlinierten Linien gezeigt ist, trichterförmig geformt wird.In the example shown, the is in the Reservoir 13 immersed end of the tube 25, the opening 26, at which a dynamic pressure forms and through which the lubricant 28 enters the tube 25. A somewhat different embodiment is shown in FIG. 2. The reservoir 13, the whorls 14, part of the carrier 21 and the tube 25 are shown in this again. According to this example, the pipe 25 comprises a pipe end piece 34 at its end located in the reservoir 13. The lubricant which co-rotates with the reservoir 13 strikes the opening 26 essentially from the left-hand side in FIG. 2, generates a dynamic pressure thereon and is driven through this into the tube 25 and in this. The pipe end piece 34 is thus bent in such a way that it extends away from the pipe 25 against the direction of rotation of the reservoir 13. It provides a more gradual redirection of the lubricant 28 from its horizontal movement upwards than is the case when a simple opening according to FIG. 1 is provided. This means that the flow resistance for the lubricant is smaller than when there is only one opening. The inflow of the lubricant can be made even easier by shaping the mouth formed by the tube end piece 34 in a funnel shape, as shown by the dashed lines.

Um dafür zu sorgen, dass kein Schmiermittel 28 nach aussen gelangen kann, was bekanntlich im Umgang mit textilen Erzeugnissen von besonderer Bedeutung ist, empfiehlt es sich, oberhalb der Stelle, an welcher das Schmiermittel aus der Ausmündung 27 des Rohres 25 austritt, um zum Halslager 23 zu gelangen, einen oelspritzring bzw. Schleuderring 32 vorzusehen, durch welchen ein weiteres Hochsteigen des Schmiermittels 28 unterbunden wird. Damit das vom Ring 32 wegspritzende Oel wieder zum Reservoir 13 zurückgelangt, muss sich der Ring 32 innerhalb des vom Gehäuse 21 umschlossenen Raumes befinden.In order to ensure that no lubricant 28 can escape to the outside, which is known to be of particular importance when dealing with textile products, it is advisable to go to the neck bearing above the point at which the lubricant emerges from the mouth 27 of the tube 25 23 to come to provide an oil splash ring or slinger 32 through which a further rise of the lubricant 28 is prevented. In order for the oil splashing away from the ring 32 to return to the reservoir 13, the ring 32 must be located within the space enclosed by the housing 21.

Die durch das Rohr 25 fliessende Menge des Schmiermittels 28 kann veränderbar gestaltet und damit den gegebenen Umständen angepasst werden. Dies wird beispielsweise erreicht, indem man den Durchflussquerschnitt des Rohres 25 beispielsweise mittels eines Ventiles oder durch Quetschen des Rohres 25 veränderbar ausführt. Anderseits kann man das Rohrenstück 34 mehr oder weniger genau gegen die Strömung des Schmiermittels richten, d. h. mehr oder weniger genau bezüglich der Rotation des Reservoirs 13 in die tangentiale Richtung positionieren. Anderseits kann durch die Bemessung der Rotationsgeschwindigkeit des anlaufenden Reservoirs 13 die geförderte Schmiermittelmenge variiert werden. Diese wird beispielsweise gross, wenn die Rotationsgeschwindigkeit des Schmiermittels 28 relativ lange auf dem Wert gehalten wird, bei welchem es gerade noch voll auf die Oeffnung 26 auftrifft.The amount of lubricant 28 flowing through the pipe 25 can be made variable and can thus be adapted to the given circumstances. This is achieved, for example, by making the flow cross section of the tube 25 changeable, for example by means of a valve or by squeezing the tube 25. On the other hand, the pipe section 34 can be directed more or less precisely against the flow of the lubricant, i. H. position more or less precisely with respect to the rotation of the reservoir 13 in the tangential direction. On the other hand, the amount of lubricant delivered can be varied by dimensioning the rotational speed of the incoming reservoir 13. This becomes large, for example, if the rotational speed of the lubricant 28 is kept at the value at which it just barely hits the opening 26 for a relatively long time.

Falls es sich als wünschenswert erweist, z. B. bei der Verwendung eines dünnflüssigen Oeles, dessen Durchflussgeschwindigkeit zu verlangsamen, so können halbdurchlässige Dichtungsscheiben 33 im Durchflussbereich der Lager 23, 24 angebracht werden.If it proves desirable, e.g. B. when using a low-viscosity oil to slow down the flow rate, semi-permeable sealing washers 33 can be attached in the flow area of the bearings 23, 24.
