Description

Bekannte Mühlenantriebssysteme umfassen eine oder mehrere Getriebestufen zur Antriebsleistungswandlung eines Elektromotors. Getriebestufen und Elektromotor bilden dabei einen eng an einen Verarbeitungsprozeß innerhalb z.B. einer Schüsselmühle, einer Mischtrommel, eines Brechers, einer Rohrmühle oder eines Drehrohrofens gekoppelten Antriebsstrang, der erheblichen Rückwirkungen des Verarbeitungsprozesses ausgesetzt ist. Üblicherweise werden Kegelradstufen zur Anbindung des Elektromotors an den Antriebsstrang verwendet.Known mill drive systems include one or more gear stages for driving power conversion of an electric motor. Gear stages and electric motor are closely linked to a processing process within e.g. a power plant coupled to a bowl mill, a mixing drum, a crusher, a tube mill or a rotary kiln, which is subject to considerable repercussions of the processing process. Usually, bevel gear stages are used to connect the electric motor to the drive train.

In DE 39 31 116 A1 ist eine Antriebsvorrichtung für eine Mühle in Vertikalbauweise beschrieben, bei der ein Gehäuse eines Vorsatzgetriebes fest mit der Mühle verschraubt ist. Hierbei ist eine exakte Ausrichtung von weit auseinander liegenden Achsen von Antriebsritzel und Zahnkranz erforderlich. Darüber hinaus bewirkt eine Einleitung axialer Mühlenkräfte über ein Axial-Drucklager in ein gemeinsames Getriebegehäuse erhebliche Belastungen für einen Verzahnungseingriff im Vorsatzgetriebe. Durch einen gemeinsamen großen Getriebe- und Mühlenlagerinnenraum wird eine schnelle Verschmutzung von Schmieröl für die Antriebsvorrichtung begünstigt. Außerdem erweist sich eine mechanische Leistungsverzweigung im Vorsatzgetriebe angesichts einer fehlenden Kompensation überzähliger Zwangskräfte als problematisch.In DE 39 31 116 A1 a drive device for a mill is described in vertical construction, in which a housing of an attachment gear is bolted to the mill. In this case, an exact alignment of widely spaced axes of the drive pinion and sprocket is required. In addition, causes an introduction of axial Mühlenkräfte via an axial thrust bearing in a common gear housing significant loads for a gearing engagement in the auxiliary gearing. By a common large gear and mill storage interior fast fouling of lubricating oil is favored for the drive device. In addition, a mechanical power split in the auxiliary gear proves to be problematic in the face of a lack of compensation excess redundant forces.

Aus JP 2005 052799 A ist eine Antriebsvorrichtung für einen vertikalen Brecher bekannt, der entweder über einen Zahnkranz an einer drehbaren Bodenscheibe oder über ein mehrstufiges Kegelradgetriebe angetrieben wird. Bedingt durch eine fehlende Einstellbeweglichkeit an einer Abtriebsstufe der Antriebsvorrichtung werden Stoßbelastungen aus dem Verarbeitungsprozeß in die Antriebsvorrichtung übertragen, insbesondere in deren Verzahnung.Out JP 2005 052799 A For example, there is known a vertical crusher drive device which is driven by either a sprocket on a rotatable bottom disc or a multi-stage bevel gear. Due to a lack of adjustment mobility at an output stage of the drive device Shock loads are transferred from the processing process in the drive device, in particular in the toothing.

WO 2008/031694 A1 offenbart ein Mühlenantriebssystem mit einem unterhalb eines Mahltellers anordenbaren Getriebe. Das Getriebe umfaßt zumindest eine Planetenstufe und weist eine vertikale Wellenlage auf. In ein Gehäuse des Getriebes ist ein elektrischer Motor integriert, der an einen Schmierstoffversorgungskreislauf des Getriebes angeschlossen ist, dessen Rotor und Stator sich vertikal erstreckende Achsen aufweisen und dessen Kühlung mittels durch das Getriebe zirkulierenden Schmierstoffs erfolgt. WO 2008/031694 A1 discloses a mill drive system having a gear unit locatable below a grinding table. The transmission comprises at least one planetary stage and has a vertical shaft position. In a housing of the transmission, an electric motor is integrated, which is connected to a lubricant supply circuit of the transmission, whose rotor and stator have vertically extending axes and whose cooling is carried out by means of circulating through the gear lubricant.

In WO 2009/068484 A1 ist ein Stirnradgetriebe mit einer oder mehreren Getriebestufen zum Antrieb einer von einem Zahnkranz umschlossenen Arbeitsmaschine beschrieben, das ein die Getriebestufen aufnehmendes Getriebegehäuse und ein auf einer Abtriebswelle einer Abtriebsstufe angeordnetes, einstellbewegliches Zahnritzel umfaßt, das mit dem Zahnkranz kämmt. Das Getriebegehäuse besteht aus einem ersten in sich steifen Gehäuseteil und aus einem zweiten starren Gehäuseteil. Der erste Gehäuseteil umschließt die Abtriebsstufe mit der Abtriebswelle und dem einstellbeweglichen Zahnritzel und weist das Getriebe überragende Seitenwände auf, die auf dem Fundament aufruhen. Der zweite Gehäuseteil ist ohne Berührung mit dem Fundament an einer Stirnseite an dem ersten Gehäuseteil befestigt.In WO 2009/068484 A1 is a spur gear with one or more gear stages for driving a gear wheel enclosed by a work machine described which includes a transmission gear housing receiving the gear and arranged on an output shaft of an output stage, adjustable movable pinion meshing with the ring gear. The gear housing consists of a first inherently rigid housing part and a second rigid housing part. The first housing part encloses the output stage with the output shaft and the adjustable pinion gear and has the transmission on outstanding side walls, which rest on the foundation. The second housing part is fastened to the first housing part without contact with the foundation on one end face.

Aus WO 2010/20287 ist ein Mühlenantriebssystem mit einer integrierten Motor-Getriebeeinheit bekannt, die einen gemeinsamen Kühlkreislauf aufweist. Die Motor-Getriebeeinheit ist auf einer Bodenplatte eines die Motor-Getriebeeinheit umfassenden Gehäuses abgestützt. In der älteren europäischen Patentanmeldung mit dem Anmeldeaktenzeichen 09011589.0 ist ein Mühlenantriebssystem mit einem unterhalb eines Mahltellers anordenbaren Getriebe mit zumindest einer Planeten- und/oder Stirnradstufe sowie einem in ein Gehäuse des Getriebes integrierten elektrischen Motor beschrieben. Außerdem umfaßt das Mühlenantriebssystem einen Umrichter mit einer zugeordneten Regelungseinrichtung zur verzahnungsspielfreien Drehzahlregelung des Motors.Out WO 2010/20287 is a mill drive system with an integrated motor-gear unit is known which has a common cooling circuit. The motor-gear unit is supported on a bottom plate of a housing comprising the motor-gear unit. In the earlier European patent application with the application file 09011589.0 a mill drive system is described with a can be arranged below a grinding table gear with at least one planetary and / or spur and an integrated in a housing of the transmission electric motor. In addition, the mill drive system comprises a converter with an associated control device for non-interlocking speed control of the motor.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Getriebemotor für ein Mühlenantriebssystem zu schaffen, das einerseits eine Vermeidung von Getriebeschäden durch Kurzunterbrechungen im Antriebsstrang und andererseits eine Reduktion von Biegekräften aus einem Mahlprozeß ermöglicht.The present invention is therefore an object of the invention to provide a geared motor for a mill drive system, on the one hand to avoid transmission damage caused by short breaks in the drive train and on the other hand, a reduction of bending forces from a grinding process.

Erfindungsgemäß wird diese Aufgabe durch einen Getriebemotor eines Mühlenantriebssystems mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den abhängigen Ansprüchen angegeben.According to the invention this object is achieved by a geared motor of a mill drive system having the features specified in claim 1. Advantageous developments of the present invention are specified in the dependent claims.

Der erfindungsgemäße Getriebemotor umfaßt ein unterhalb eines Mahltellers oder seitlich einer Mahltrommel anordenbares Getriebe mit zumindest einer Planetenradstufe, das eine vertikale oder horizontale Wellenlage aufweist. Außerdem ist in ein Gehäuse des Getriebes ein elektrischer Motor integriert, der an einen Schmierstoffversorgungskreislauf des Getriebes angeschlossen ist. Rotor und Stator des Motors weisen sich parallel zur Wellenlage des Getriebes erstreckende Achsen auf. Eine Kühlung des Motors erfolgt mittels durch das Getriebe zirkulierenden Schmierstoffs. Darüber hinaus ist eine schmieröldichte Ummantelung für Rotor- bzw. Statorwicklungen des Motors zur Abdichtung gegenüber innerhalb des Gehäuses zirkulierendem Schmierstoff vorgesehen. Des weiteren umfaßt das erfindungsgemäße Mühlenantriebssystem einen Umrichter mit einer zugeordneten Regelungseinrichtung zur verzahnungsspielfreien Drehzahlregelung des Motors. Ein Hohlrad der zumindest einen Planetenradstufe ist sowohl vom Rotor als auch vom Stator radial umgeben. Rotor und Stator sind vorzugsweise konzentrisch zum Hohlrad angeordnet. Durch eine Anordnung des Motors um das Hohlrad kann eine verkürzte Baulänge realisiert werden. Hieraus resultiert eine minimierte Biegearmlänge für Hebelkräfte aus einem Mahlprozeß. Aufgrund der Anordnung des Motors um das Hohlrad ist auch ein Entfall einer Kardanverbindung zwischen Motor und Getriebe sowie eines externen Motorfundaments möglich.The geared motor according to the invention comprises a gear which can be arranged below a grinding plate or laterally of a grinding drum and has at least one planetary gear stage which has a vertical or horizontal shaft position. In addition, an electric motor is integrated in a housing of the transmission, which is connected to a lubricant supply circuit of the transmission. Rotor and stator of the motor have axes extending parallel to the shaft position of the gearbox. Cooling of the engine takes place by means of circulating lubricant through the gearbox. In addition, a lubricating oil-tight casing for rotor or stator windings of the motor to seal against within the housing provided circulating lubricant. Furthermore, the mill drive system according to the invention comprises a converter with an associated control device for the non-interlocking speed control of the motor. A ring gear of the at least one planetary gear is radially surrounded by both the rotor and the stator. Rotor and stator are preferably arranged concentrically to the ring gear. By arranging the motor around the ring gear, a shortened overall length can be realized. This results in a minimized Biegearmlänge for leverage forces from a grinding process. Due to the arrangement of the engine around the ring gear and a elimination of a cardan connection between the engine and transmission and an external engine foundation is possible.

Aufgrund einer Integration des Motors in den Schmierstoffkreislauf des Getriebes kann auf aufwendige Belüftungsmaßnahmen zur ausreichenden Kühlung des Motors verzichtet werden. Durch Verwendung eines Umrichters zur Motordrehzahlregelung wird Entkopplung zwischen Netzversorgung und Motordrehmoment erzielt. Auf diese Weise können Verzahnungsschäden bei Kurzunterbrechungen infolge eines Netzausfalls vermieden werden, da durch einen Netzausfall aufgrund der erfindungsgemäßen Drehzahlregelung des Motors kein Verzahnungsspiel in Drehrichtung im Getriebe hervorgerufen wird. Durch eine komplett vertikale oder horizontale Anordnung von Mahlteller, Getriebe und Motor ist außerdem ein Verzicht auf verhältnismäßig teuere Kegelradgetriebe möglich. Durch den Verzicht auf Kegelradgetriebe und eine Luftkühlung des Motors werden außerdem Geräuschemissionen deutlich reduziert.Due to an integration of the engine in the lubricant circuit of the transmission can be dispensed with complex ventilation measures for sufficient cooling of the engine. By using an inverter for motor speed control decoupling between mains supply and motor torque is achieved. In this way, tooth damage during short interruptions due to a power failure can be avoided, as caused by a power failure due to the inventive speed control of the engine no gear play in the direction of rotation in the transmission. By a complete vertical or horizontal arrangement of grinding table, gearbox and engine is also a waiver of relatively expensive bevel gear possible. By eliminating bevel gear and air cooling of the engine noise emissions are also significantly reduced.

Durch Verwendung eines Umrichters kann eine Vielzahl anwendungsspezifischer Übersetzungsvarianten bei reduzierter Anzahl von Verzahnungsbauteiletypen realisiert werden. Durch die Drehzahlregelung kann der jeweilige Verarbeitungsprozeß mit dem erfindungsgemäßen Mühlenantriebssystem darüber hinaus in einem optimalen Arbeitspunkt betrieben werden. Hierdurch wird die Effizienz des Mahlprozesses verbessert. Dies ermöglicht wiederum eine Energieverbrauchsreduktion.By using an inverter, a variety of application-specific translation variants can be realized with a reduced number of Verzahnungsbauteiletypen. By the speed control, the respective processing process Moreover, with the mill drive system according to the invention, they can be operated at an optimum operating point. This improves the efficiency of the milling process. This in turn allows a reduction in energy consumption.

Der Motor kann beispielsweise als Außenläufer ausgeführt sein. Dabei bildet das Hohlrad einen Statorträger. Entsprechend einer weiteren Ausgestaltung der vorliegenden Erfindung ist eine Sonnenradwelle der zumindest einen Planetenradstufe mit einem Rotorträger verbunden. In dem Rotorträger kann zumindest eine sich axial erstreckende Öffnung für einen Schmierstoffablauf vom Getriebe in einen Schmierstoffsammelbereich oder -behälter vorgesehen sein. Alternativ zu einer Ausgestaltung als Außenläufer kann der Motor auch als Innenläufer ausgeführt sein. In diesem Fall ist das Hohlrad vorzugsweise drehfest mit dem Rotor verbunden.The engine may be designed, for example, as an external rotor. The ring gear forms a stator. According to a further embodiment of the present invention, a sun gear shaft of the at least one planetary gear is connected to a rotor carrier. At least one axially extending opening may be provided in the rotor carrier for a lubricant outlet from the transmission into a lubricant collecting area or container. As an alternative to a configuration as external rotor, the motor can also be designed as an internal rotor. In this case, the ring gear is preferably rotatably connected to the rotor.

Entsprechend einer bevorzugten Ausgestaltung der vorliegenden Erfindung sind Dichtungen nur noch an einem Abtriebsteller, an Schmierstoffversorgungsleitungen, an elektrischen Energieversorgungszuführungen und an zumindest einer Zuführung für eine Meßeinrichtung vorgesehen. Dies ermöglicht eine weitere Reduktion mechanischer Bauteile und trägt damit zu einer erhöhten Zuverlässigkeit bei.According to a preferred embodiment of the present invention, seals are provided only on a driven plate, on lubricant supply lines, on electrical power supply leads and on at least one feed for a measuring device. This allows a further reduction of mechanical components and thus contributes to increased reliability.

Entsprechend einer vorteilhaften Weiterbildung der vorliegenden Erfindung ist der Motor eine permanenterregte Synchronmaschine ist, deren Rotor-Magnetsystem in einen Edelstahlmantel eingeschweißt ist. Da am Rotor auf diese Weise keine thermischen Verluste entstehen, ist keine Rotorkühlung erforderlich. Alternativ zu einer permanenterregten Synchronmaschine kann der Motor auch als Kurzschlußläufermaschine ausgestaltet sein.According to an advantageous development of the present invention, the motor is a permanent-magnet synchronous machine whose rotor magnet system is welded into a stainless steel jacket. Since no thermal losses occur on the rotor in this way, no rotor cooling is required. As an alternative to a permanent-magnet synchronous machine, the motor can also be designed as a squirrel cage machine.

Die vorliegende Erfindung wird nachfolgend an einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigt die

The present invention will be explained in more detail using an exemplary embodiment with reference to the drawing. It shows the
figure
a mill drive system with a geared motor according to the invention in a sectional view.

Das in der Figur dargestellte Mühlenantriebssystem umfaßt ein unterhalb eines Mahltellers angeordnetes Getriebe 1 mit zwei Planetenstufen. Sowohl die antriebsseitige Planetenstufe als auch die abtriebsseitige Planetenstufe weisen eine vertikale Wellenlage auf. Beide Planetenstufen umfassen jeweils ein Hohlrad, einen Planetenträger mit darin gelagerten Planetenrädern und ein Sonnenrad. Die Hohlräder der Planetenstufen sind fest mit einem Getriebegehäuse 11 verbunden. Der Planetenträger der abtriebsseitigen Planetenstufe ist mit dem Mahlteller verbindbar und mittels eines Axiallagers 13 gelagert. Das Sonnenrad der antriebsseitigen Planetenstufe ist mit einer Rotorwelle 28 eines in das Getriebegehäuse 11 integrierten elektrischen Motors 2 verbunden, der einen Rotor 21 und einen diesen radial umgebenden Stator 22 umfaßt. Rotor 21 und Stator 22 weisen sich vertikal erstreckende Achsen auf.The mill drive system shown in the figure comprises a arranged below a Mahltellers gear 1 with two planetary stages. Both the drive-side planetary stage and the output-side planetary stage have a vertical shaft position. Both planetary stages each include a ring gear, a planetary carrier with planetary gears mounted therein, and a sun gear. The ring gears of the planetary stages are fixedly connected to a transmission housing 11. The planet carrier of the driven-side planetary stage can be connected to the grinding table and mounted by means of a thrust bearing 13. The sun gear of the drive-side planetary stage is connected to a rotor shaft 28 of an electric motor 2 integrated into the transmission housing 11, which rotor comprises a rotor 21 and a stator 22 surrounding it radially. Rotor 21 and stator 22 have vertically extending axes.

Das Hohlrad 14 der antriebsseitigen Planetenradstufe ist sowohl vom Rotor 21 als auch vom Stator 22 radial umgeben. Dabei sind Rotor 21 und Stator 22 konzentrisch zum Hohlrad 14 der antriebsseitigen Planetenradstufe angeordnet. Im vorliegenden Ausführungsbeispiel ist der Motor 2 als Außenläufer ausgeführt. Das Hohlrad 14 der antriebsseitigen Planetenradstufe bildet hierbei einen Statorträger. Die Rotorwelle 28 bzw. eine Sonnenradwelle der antriebsseitigen Planetenradstufe ist mit einem Rotorträger 27 verbunden, auf dem der Rotor 21 abgestützt ist.The ring gear 14 of the input-side planetary gear is radially surrounded by both the rotor 21 and the stator 22. Rotor 21 and stator 22 are arranged concentrically to the ring gear 14 of the input-side planetary gear. In the present embodiment, the motor 2 is designed as an external rotor. The ring gear 14 of the drive-side planetary gear here forms a stator. The rotor shaft 28 or a sun gear shaft of the drive-side planetary gear stage is connected to a rotor carrier 27, on which the rotor 21 is supported.

Alternativ zu einer in der Figur dargestellten Ausgestaltung als Außenläufer könnte der Motor 2 grundsätzlich auch als Innenläufer ausgeführt sein. In diesem Fall kann das Hohlrad 14 der antriebsseitigen Planetenradstufe drehfest mit dem Rotor 21 verbunden werden.As an alternative to a configuration shown as an external rotor in the figure, the motor 2 could in principle also be designed as an internal rotor. In this case, the ring gear 14 of the drive-side planetary gear can be rotatably connected to the rotor 21.

Die Rotorwelle 28 ist mittels eines zwischen Motor 2 und Getriebe 1 angeordneten Radiallagers 24, eines unterhalb des Motors 2 in einem Schmierstoffsumpf 12 angeordneten Radiallagers 25 sowie eines ebenfalls unterhalb der Motors 2 angeordneten Axiallagers 26 gelagert. Auf diese Weise ist bei einer relativ kurzen Rotorwelle 28 eine sehr gute Zentrierung des Rotors 21 möglich. Rotorwelle 28 und Sonnenrad der antriebsseitigen Planetenstufe sind vorzugsweise über eine unterhalb oder oberhalb des Motors 2 angeordnete Kupplung verbunden. Darüber hinaus sind im vorliegenden Ausführungsbeispiel der Planetenträger der antriebsseitigen Planetenstufe und das Sonnenrad der abtriebsseitigen Planetenstufe miteinander verbunden.The rotor shaft 28 is mounted by means of a radial bearing 24 arranged between the engine 2 and the transmission 1, a radial bearing 25 arranged below the motor 2 in a lubricant sump 12, and an axial bearing 26 also arranged below the motor 2. In this way, with a relatively short rotor shaft 28, a very good centering of the rotor 21 is possible. Rotor shaft 28 and sun gear of the drive-side planetary stage are preferably connected via a coupling arranged below or above the motor 2. In addition, in the present embodiment, the planet carrier of the drive-side planetary stage and the sun gear of the output-side planetary stage are interconnected.

Der Motor 2 ist an einen Schmierstoffversorgungskreislauf des Getriebes 1 angeschlossen, bei dem Schmierstoff aus dem Schmierstoffsumpf 12 zu Schmierungsstellen im Getriebe 1 gepumpt wird und von dort über den Motor 2 in den Schmierstoffsumpf 12 abläuft. Auf diese Weise erfolgt eine Kühlung des Motors 2 mittels durch das Getriebe 1 zirkulierenden Schmierstoffs. Zumindest ein in der Figur nicht explizit dargestellter Schmierstoffversorgungskanal ist hierbei zu Statorkühlblechen geführt, die mit durch das Getriebe 1 zirkulierendem Schmierstoff anströmbar sind. Zusätzlich kann gezielt Schmieröl zur Kühlung des Stators 22 angesprüht werden, das durch Kühleinrichtungen des Stators 22 gefördert wird.The engine 2 is connected to a lubricant supply circuit of the transmission 1, in which lubricant from the lubricant sump 12 is pumped to lubrication points in the gearbox 1 and runs from there via the engine 2 into the lubricant sump 12. In this way, there is a cooling of the engine 2 by means of circulating through the gear 1 lubricant. At least one lubricant supply channel, not explicitly shown in the figure, is here guided to stator cooling plates, which can be flowed in with lubricant circulating through the transmission 1. In addition, lubricating oil can be sprayed specifically for cooling the stator 22, which is conveyed through cooling devices of the stator 22.

Am Rotorträger 27 ist eine schmieröldichte Ummantelung des Rotors 21 zur Abdichtung gegenüber innerhalb des Gehäuses zirkulierendem Schmierstoff vorgesehen. In entsprechender Weise schließt sich an einen Luftspalt zwischen Rotor 21 und Stator 22 in radialer Richtung eine schmieröldichte Ummantelung eines Ständerblechpakets an, das Wicklungen des Stators 22 umfaßt. Eine deutliche Vergrößerung des Luftspalts des Motors 2 ist nicht erforderlich, da dieser durch die schmieröldichten Ummantelungen lediglich eine geringe Vergrößerung erfährt. Der Motor 2 ist im vorliegenden Ausführungsbeispiel eine permanenterregte Synchronmaschine, deren Rotor-Magnetsystem in einen Edelstahlmantel eingeschweißt ist. Dies ermöglicht besonders geringe elektrische Verluste.On the rotor support 27 a lubricating oil-tight sheath of the rotor 21 is provided for sealing against circulating within the housing lubricant. In a corresponding manner is followed by an air gap between the rotor 21 and stator 22 in the radial direction, a lubricating oil-tight sheathing of a stator core, which includes windings of the stator 22. A significant increase in the air gap of the engine 2 is not required, as it undergoes only a small magnification by the oil-tight sheaths. The motor 2 is in the present embodiment, a permanent-magnet synchronous machine whose rotor magnet system is welded in a stainless steel sheath. This allows particularly low electrical losses.

Das in der Figur dargestellte Mühlenantriebssystem weist ferner einen Umrichter 23 mit einer zugeordneten Regelungseinrichtung zur verzahnungsspielfreien Drehzahlregelung des Motors 2 auf, so daß zwischen Zahnflanken des Getriebes 1 in Drehrichtung kein Spiel besteht. Mechanische Eigenfrequenzen eines Mühle-Getriebe-Motor-Systems werden bei Verwendung des Umrichters 23 unkritisch infolge einer Systemkomponenten-Entkoppelung. Zahnflanken des Getriebes 1 werden dabei durch Aufschaltung eines Mindestdrehmoments unter ständigem Kraftschluß gehalten. Hierdurch werden richtungsändernde Belastungen der Zahnflanken weitgehend unterbunden.The mill drive system shown in the figure further comprises a converter 23 with an associated control device for non-interlocking speed control of the motor 2, so that there is no play between the tooth flanks of the transmission 1 in the direction of rotation. Mechanical natural frequencies of a mill gearbox engine system become uncritical when using the inverter 23 due to system component decoupling. Tooth flanks of the transmission 1 are held by applying a minimum torque under constant adhesion. As a result, direction-changing loads on the tooth flanks are largely prevented.

Die Anwendung der vorliegenden Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt.The application of the present invention is not limited to the described embodiment.
