Abstract
Description
Die Erfindung betrifft eine Motorspindel mit einer Kühleinheit nach dem Oberbegriff des Anspruchs 1.The The invention relates to a motor spindle with a cooling unit according to the preamble of claim 1.
Motorspindeln bzw. Motorfrässpindeln sind üblicherweise mit integrierten Elektromotoren, insbesondere Drehstrom-Synchron- oder Asynchronmotoren ausgerüstet. Im Betrieb der Spindeln entstehen Verluste sowohl an mechanischen Bauelementen wie Kugellagern, etc. als auch als elektrische Verluste im Elektromotor. Aus diesem Grund benötigen Motorspindeln eine Kühlung, die bislang als Flüssigkeits- bzw. Wasserkühlung ausgeführt wird.motor spindles or motor milling spindles are common with integrated electric motors, in particular three-phase synchronous or asynchronous motors equipped. In the operation of the spindles losses occur both on mechanical Components such as ball bearings, etc. as well as electrical losses in the electric motor. For this reason, motor spindles need a cooling, the so far as liquid or water cooling accomplished becomes.
Aufgabe der Erfindung ist es, eine Motorspindel, insbesondere für eine Werkzeugmaschine, mit einer ein Kühlfluid umfassenden Kühleinheit zum Kühlen der Motorspindel, vorzuschlagen, die wirtschaftlich besonders günstig herstellbar und/oder besonders kompakt ausbildbar ist.task The invention relates to a motor spindle, in particular for a machine tool, with a cooling fluid comprehensive cooling unit for cooling the motor spindle, to propose, the economical to produce particularly favorable and / or is particularly compact formable.
Diese Aufgabe wird, ausgehend von einer Motorspindel der einleitend beschriebenen Art, durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch die in den Unteransprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.These Task is, starting from a motor spindle described in the introduction Art, solved by the characterizing features of claim 1. By in the subclaims mentioned measures are advantageous embodiments and further developments of the invention possible.
Dementsprechend zeichnet sich eine erfindungsgemäße Spindel dadurch aus, dass das Kühlfluid als Kühlgas, insbesondere als Kühlluft, ausgebildet ist. Hierdurch kann eine besonders wirtschaftlich günstige Motorspindel realisiert werden. Die Luft kann ohne Aufwand aus der Umgebung angesaugt und wieder an diese abgegeben werden. Aufwendige Zu- und Abführleitungen oder dergleichen können entfallen.Accordingly is a spindle according to the invention characterized in that the cooling fluid as a cooling gas, especially as cooling air, is trained. This allows a particularly economical motor spindle will be realized. The air can be sucked in and out of the environment without any hassle be returned to this again. Elaborate supply and discharge lines or the like can be omitted.
Vorzugsweise umfasst ein Statorgehäuse wenigstens ein Kühlfluid- bzw. Luftkanal zur Durchleitung des Kühlgases, wobei in Umfangsrichtung des Statorgehäuses mehrere Kühlkanäle angeordnet sind. Hiermit wird die Kühlung besonders effizient.Preferably includes a stator housing at least a cooling fluid or air duct for the passage of the cooling gas, wherein in the circumferential direction of the stator housing a plurality of cooling channels are arranged. This will cool especially efficient.
Vorteilhafterweise ist wenigstens ein Gebläse oder ein Ventilator zum Erzeugen einer Strömung des Kühlfluids vorgesehen. Dies erhöht den Volumenstrom der Kühlung und bewirkt somit eine bessere Abwärmeabfuhr.advantageously, is at least a fan or a fan for generating a flow of the cooling fluid is provided. This increases the volume flow the cooling and thus causes a better waste heat removal.
In einer besonderen Weiterbildung der Erfindung kann ein Gebläse oder ein Lüfter verwendet werden, die im Wesentlichen bereits handelsüblichen sind und die z.B. bereits in großer Stückzahl eingesetzt werden.In a particular embodiment of the invention, a fan or a fan are used, which are essentially already commercially available and the e.g. already in great quantity be used.
Gemäß einer Variante der Erfindung ist das Gebläse oder der Ventilator wenigstens teilweise innerhalb, insbesondere im Wesentlichen vollständig innerhalb eines Statorgehäuses angeordnet. Hiermit wird die Motorspindel sehr kompakt.According to one Variant of the invention is the blower or the fan at least partially within, in particular substantially completely within a stator housing arranged. This makes the motor spindle very compact.
Vorzugsweise ist wenigstens ein polygonförmiger, insbesondere im Wesentlichen viereckiger Querschnitt eines Statorgehäuses vorgesehen. Hiermit entstehen Eckbereiche in Bezug zum kreisrunden Querschnitt des Elektromotors bzw. Stators/Rotors, die in vorteilhafter Weise zur Aufnahme von Leitungen und/oder für Kühlkanäle verwendbar sind.Preferably is at least a polygonal, in particular provided substantially square cross-section of a stator. This creates corner areas in relation to the circular cross-section of the electric motor or stator / rotor, in an advantageous manner can be used for receiving lines and / or for cooling channels.
Vorteilhafterweise ist wenigstens in einem Eckbereich des Statorgehäusequerschnitts der Kühlfluid- bzw. Luftkanal angeordnet.advantageously, is at least in a corner region of the Statorgehäusequerschnitts the cooling fluid or air duct arranged.
Vorzugsweise ist der Kühlkanal, insbesondere Luftkanal in Strömungsrichtung des Kühlfluids vor einer Druckerzeugungseinheit, insbesondere dem Gebläse oder dem Ventilator, angeordnet. Hiermit wird das Kühlgas bzw. die Kühlluft durch die Kanäle gesaugt. Dies bedeutet u.a., dass die Einströmende Luft diffus zu den Kanälen strömen kann und dann kontrolliert durch diese hindurch strömen und wieder kontrolliert die Motorspindel verlassen kann. Dies vereinfacht das Kühlsystem.Preferably is the cooling channel, in particular air duct in the flow direction of the cooling fluid before a pressure generating unit, in particular the blower or the fan, arranged. Hereby, the cooling gas or the cooling air is through sucked the channels. This means, inter alia, that the inflowing air can flow diffusely to the channels and then flow controlled through them and controlled again leave the motor spindle. This simplifies the cooling system.
In einer besonderen Weiterbildung der Erfindung ist eine Verbindung zwischen den Kühlkanälen in den Ecken bzw. Eckbereichen und den Wickelköpfen des Stators des Elektqromotors vorgesehen. Hierdurch wird das Kühlfluid bzw. die Kühlluft nicht nur an der äußeren Mantelfläche des Motors vorbeigeleitet, sondern ein Teil des Kühlgases bzw. der Luft kann über den Wickelkopf in den Motorraum eindringen, am Wickelkopf vorbei strömen und danach über dem hinteren Wickelkopf wieder in den Kanal zur Lüftereinheit strömen. Diese Art der Kühlung kann als sogenannter innen belüfteter Motor bezeichnet werden und weist eine noch zusätzliche, deutlich größere Effizienz auf, als dies durch ein reines am Statoraußendurchmesser vorbeiströmendes Kühlprinzip realisierbar ist.In a particular embodiment of the invention is a compound between the cooling channels in the Corners or corners and the winding heads of the stator of the Elektqromotors intended. As a result, the cooling fluid or the cooling air not only on the outer surface of the Motors bypassed, but a portion of the cooling gas or the air can over the Penetrate the winding head into the engine compartment, flow past the winding head and after that over the feed the rear winding head back into the duct to the fan unit. These Type of cooling can be used as a so-called ventilated interior Engine and has an additional, significantly greater efficiency on, as this can be realized by a pure flowing past the stator outer diameter cooling principle is.
