Abstract
Description
Die Erfindung betrifft eine Schmiervorrichtung umfassend eine Zahnradpumpe und einen die Zahnradpumpe antreibenden Antriebsmotor, wobei die Zahnradpumpe Schmierstoff von einer Schmierstoffzufuhr zu einem Schmierstoffauslass fördern kann.The invention relates to a lubricating device comprising a gear pump and a drive motor driving the gear pump, wherein the gear pump can deliver lubricant from a lubricant supply to a lubricant outlet.
Bei gattungsgemäßen Schmiervorrichtungen werden vorteilhaft Zahnradpumpen eingesetzt, um einen Schmierstoff, insbesondere Schmieröl, zu fördern. Zahnradpumpen eigenen sich besonders gut für das Fördern von Flüssigkeiten. Für eine stabile Förderung bedarf es in Abhängigkeit der Viskosität der Flüssigkeit einer Mindestgeschwindigkeit der Zahnräder in der Zahnradpumpe. Die Mindestgeschwindigkeit ist erforderlich, damit die zu fördernde Flüssigkeit trotz Zahnkopfspiel und gegebenenfalls anderer vorhandener Leckagestellen möglichst verlustfrei von der Ansaugstelle zum Druckbereich transportiert wird. Das gilt für kleine und große Fördermengen gleichermaßen. Bei besonders kleinen Mengen (z.B. im Falle einzelner Tropfen) muss neben der Mindestgeschwindigkeit auch noch die Anzahl der Umdrehungen in engen Grenzen gehalten werden. Dabei kann auch zur Förderung nur eines einzelnen Tropfens weniger als eine volle Umdrehung der Zahnräder erforderlich sein. In generic lubricating devices gear pumps are advantageously used to promote a lubricant, in particular lubricating oil. Gear pumps are particularly suitable for pumping liquids. For stable delivery, depending on the viscosity of the liquid, a minimum speed of the gears in the gear pump is required. The minimum speed is required so that the liquid to be conveyed despite possible tooth head clearance and possibly other existing leakage points is transported as lossless as possible from the suction to the pressure area. This applies equally to small and large volumes. In the case of very small quantities (for example in the case of single drops), in addition to the minimum speed, the number of revolutions must also be kept within narrow limits. It may also be required to promote only a single drop less than a full revolution of the gears.
Herkömmliche Elektromotoren, die für den Antrieb von Zahnradpumpen eingesetzt werden, erreichen zwar mühelos die Mindestgeschwindigkeit. Konstruktionsbedingt sind sie jedoch nicht in der Lage, einen exakt definierten Winkel zu drehen, also beispielsweise eine Drehung des Zahnrades um 270° vorzunehmen, um eine kleine Menge Schmieröl zu fördern. Deshalb ist es mit den bislang eingesetzten Motoren auch nicht möglich, sehr kleine Ölmengen (im Bereich von wenigen Öltropfen pro Minute) gleichmäßig wiederkehrend zu fördern. Gerade dieser Anwendungsfall ist aber durchaus relevant beispielsweise für die Zentralschmierung einer Maschine oder Anlage.Conventional electric motors used to power gear pumps easily reach the minimum speed. Due to the design, however, they are not able to rotate a precisely defined angle, so for example make a rotation of the gear 270 ° to promote a small amount of lubricating oil. Therefore, with the motors used so far, it is also not possible to convey very small amounts of oil (in the range of a few drops of oil per minute) in a uniformly recurring manner. Especially this application is quite relevant, for example, for the central lubrication of a machine or plant.
Bisher wurde im Falle dessen, dass sehr kleine Schmieröl-Mengen gefördert werden müssen, nicht Zahnradpumpen eingesetzt, sondern beispielsweise entsprechend ausgelegte Kolbenpumpen oder Schlauchpumpen. Je nach Einsatzfall ist auch die Aufteilung eines größeren Volumens in mehrere kleine Einzelvolumina möglich, wofür Progressivverteiler eingesetzt werden können. Die nicht benötigten Einzelvolumina können dann über Leitungen in das Schmierölreservoir zurückgeführt werden. So far, in the case of the fact that very small amounts of lubricating oil must be promoted, not gear pumps used, but for example, appropriately designed piston pumps or peristaltic pumps. Depending on the application, the division of a larger volume into several small individual volumes is possible, for which progressive distributors can be used. The unused individual volumes can then be returned via lines in the lubricating oil reservoir.
Der Erfindung liegt die Aufgabe zugrunde, eine Schmiereinrichtung der eingangs genannten Art – also bei Einsatz einer Zahnradpumpe als Förderelement – so fortzubilden, dass es möglich wird, auch sehr kleine Volumina an Schmierstoff präzise fördern zu können, um somit auf wechselnde Betriebsbedingungen einer zu schmierenden Anlage schnell zu optimal reagieren zu können.The invention has the object of providing a lubrication device of the type mentioned - so with the use of a gear pump as a conveying element - educate so that it is possible to convey even very small volumes of lubricant precisely, so as to changing operating conditions of a system to be lubricated to react quickly to optimal.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass der Antriebsmotor als Schrittmotor ausgebildet ist.The solution of this problem by the invention is characterized in that the drive motor is designed as a stepper motor.
Der Schrittmotor kann als Reluktanzschrittmotor oder als Permanentmagnetschrittmotor ausgebildet sein. The stepper motor may be designed as a reluctance stepper motor or as a permanent magnet stepper motor.
Ein Schrittmotor ist zumeist ein Synchronmotor, bei dem der Rotor, d. h. das drehbare Motorteil samt Welle, durch ein gesteuertes schrittweise rotierendes elektromagnetisches Feld der Statorspulen, d. h. des nicht drehbaren Motorteils, um einen minimalen Winkel (Schritt) oder sein Vielfaches gedreht werden kann. A stepper motor is usually a synchronous motor in which the rotor, i. H. the rotatable motor part including shaft, by a controlled stepwise rotating electromagnetic field of the stator coils, d. H. of the non-rotatable motor part, by a minimum angle (step) or its multiple can be rotated.
Ist der Schrittmotor als Reluktanzschrittmotor ausgeführt, besteht der Rotor aus einem gezahnten Weicheisenkern. Bei diesem Material verschwindet nach dem Ausschalten des Statorstromes das Magnetfeld. Bei eingeschaltetem Strom fließt der magnetische Fluss durch den Weicheisenkern des Rotors. Die Drehbewegung des Rotors kommt zustande, weil vom gezahnten Stator der nächstliegende Zahn des Rotors angezogen wird, da sich so der magnetische Widerstand verringert.If the stepper motor is designed as a reluctance stepper motor, the rotor consists of a toothed soft iron core. With this material disappears after switching off the stator current, the magnetic field. When the power is on, the magnetic flux flows through the soft iron core of the rotor. The rotational movement of the rotor comes about because of the toothed stator, the nearest tooth of the rotor is tightened, as this reduces the magnetic resistance.
Ist der Schrittmotor als Permanentmagnetschrittmotor ausgebildet, besteht der Stator aus Weicheisen und der Rotor aus Dauermagneten, die abwechselnd einen Nordund einen Südpol aufweisen. Mit dem Stator-Magnetfeld richtet man den dauermagnetischen Rotor so aus, dass eine Drehbewegung entsteht.If the stepping motor is designed as a permanent magnet stepping motor, the stator consists of soft iron and the rotor of permanent magnets, which alternately have a north and a south pole. With the stator magnetic field, the permanent-magnetic rotor is aligned so that a rotational movement occurs.
Der Schrittmotor kann mit einer Steuer- oder Regeleinrichtung in Verbindung stehen. In diesem Falle ist gemäß einer Weiterbildung vorgesehen, dass im Bereich des Schmierstoffauslasses ein Durchflussmengenmesser für ausgebrachten Schmierstoff angeordnet ist, der mit der Steuer- oder Regeleinrichtung in Verbindung steht. Damit wird es möglich, die ausgebrachte Menge an Schmierstoff im geschlossenen Regelkreis gemäß einer Vorgabe zu regeln. The stepper motor may be in communication with a control device. In this case, it is provided according to a development that in the area of the lubricant outlet, a flow meter for discharged lubricant is arranged, which is in communication with the control or regulating device. This makes it possible to regulate the applied amount of lubricant in the closed loop according to a specification.
Zwischen dem Schrittmotor und der Zahnradpumpe kann ein Kupplungselement zum Ausgleich eines radialen Versatzes angeordnet sein. Between the stepping motor and the gear pump, a coupling element may be arranged to compensate for a radial offset.
In Fließrichtung des Schmierstoffs vor der Zahnradpumpe kann eine Ansaugkammer angeordnet sein, die mit einer Ansaugbohrung der Zahnradpumpe fluidisch in Verbindung steht. Die Schmierstoffzufuhr mündet dabei bevorzugt in die Ansaugkammer. In the flow direction of the lubricant in front of the gear pump, a suction chamber may be arranged, which is in fluid communication with a suction bore of the gear pump. The lubricant supply preferably opens into the suction chamber.
Die Zahnradpumpe und der Schrittmotor können in einem gemeinsamen Gehäuse untergebracht sein. Das Gehäuse ist dabei bevorzugt zweiteilig ausgebildet; jedes Teil des zweiteiligen Gehäuses kann einen Aufnahmebereich für die Zahnradpumpe und einen Aufnahmebereich für den Schrittmotor aufweisen. The gear pump and the stepper motor may be housed in a common housing. The housing is preferably formed in two parts; Each part of the two-part housing may have a receiving area for the gear pump and a receiving area for the stepping motor.
Im Bereich des Schmierstoffauslasses kann ein Rückschlagventil angeordnet sein. In the area of the lubricant outlet, a check valve may be arranged.
Mit der vorgeschlagenen Lösung ist es möglich, eine variable Kleinstmengenförderung von Schmierstoff zu bewerkstelligen, wozu der Schrittmotor entsprechend angesteuert wird. With the proposed solution, it is possible to accomplish a variable smallest amount promotion of lubricant, for which purpose the stepper motor is driven accordingly.
Die Erfindung stellt also eine Kleinstmengendosierung für sehr kleine Fördervolumina unter Verwendung eines Schrittmotors als Antrieb einer Zahnradpumpe zur Verfügung, wodurch sich das Fördervolumen elektrisch variabel verändern lässt, um somit auf wechselnde Betriebsbedingungen sofort und mit exakten Schmierstoffmengen reagieren zu können.Thus, the invention provides a mini-dosage for very small volumes using a stepper motor as a drive gear pump available, whereby the delivery volume can be changed electrically variable, so as to be able to react to changing operating conditions immediately and with exact amounts of lubricant can.
Der Erfindungsvorschlag kann überall dort eingesetzt werden, wo wechselnde Betriebsbedingungen ein variables und exakt einstellbares Schmierstoff-Fördervolumen erfordern. Als Beispiel sei eine Kompressorschmierung genannt. The proposed invention can be used wherever changing operating conditions require a variable and exactly adjustable lubricant delivery volume. An example is a compressor lubrication called.
Durch die Möglichkeit einer schrittweisen Drehung der Zahnräder der Zahnradpumpe kann eine individuelle Festlegung der Fördermenge erfolgen, was auf einen Kubikmillimeter genau erfolgen kann. Due to the possibility of a stepwise rotation of the gears of the gear pump, an individual determination of the flow rate can be done, which can be done to a cubic millimeter exactly.
Dadurch kann das Schmiersystem exakt jene Schmierstoff-Menge an eine Schmierstelle liefern, die dort tatsächlich benötigt wird. Ein Überschmieren, wie es bei vielen anderen Systemen durch ungünstige Abstufungen oft auftritt, kann verhindert werden. This allows the lubrication system to deliver exactly that amount of lubricant to a lubrication point that is actually needed there. Over-lubrication, which often occurs with unfavorable gradations in many other systems, can be prevented.
Somit kann eine bedarfsgerechte Schmierung erfolgen, die die Umwelt schont und Kosten spart. Thus, a demand-based lubrication can take place, which protects the environment and saves costs.
