Description

Die Erfindung betrifft eine Vorrichtung zum Schleifen und Entgraten eines flächigen Werkstücks gemäß dem Oberbegriff des ersten Patentanspruchs.The invention relates to a device for grinding and deburring a flat workpiece according to the preamble of the first claim.

Beim Stanzen oder Schneiden von Stahlblech, das durchaus mehrere Zentimeter dick sein kann, bilden sich an der Oberseite störende Grate. Diese können mittels einer Schleifwalze abgeschliffen werden. Hierzu wird das Werkstück mittels eines geeigneten Transportmechanismus unter der sich relativ schnell drehenden Schleifwalze vorbeigeführt.When punching or cutting sheet steel, which can be several centimeters thick, annoying burrs form on the top. These can be abraded by means of a grinding roller. For this purpose, the workpiece is passed by means of a suitable transport mechanism under the relatively fast rotating grinding roller.

DE 10 2007 048 544 A1 beschreibt eine Vorrichtung zum Schleifen eines flächigen Werkstücks mit einer Schleifwalze, die von einem Elektromotor über Keilriemenscheiben und Keilriemen angetrieben wird. Die Schleifwalze ist an der Umfangsoberfläche mit einem Schleifpapier oder Schleifleinen belegt. DE 10 2007 048 544 A1 describes a device for grinding a flat workpiece with a grinding roller, which is driven by an electric motor via V-belt pulleys and V-belt. The abrasive roller is coated on the peripheral surface with a sandpaper or abrasive cloth.

Eine statisch gelagerte Schleifwalze nutzt sich ungleichmäßig ab, da immer wieder dieselben Stellen des Schleifbelags über die Oberfläche der Werkstücke schleifen. In der deutschen Offenlegungsschrift 1 502 538 wird deshalb vorgeschlagen, die Schleifwalze in Querrichtung hin- und herzubewegen, um ein gleichmäßiges Abnutzen der Schleifwalze zu bewirken. Als möglicher Mechanismus zur Erzeugung der Hin- und Her-Bewegung der Schleifwalze in Querrichtung wird ein Kurbelstangenantrieb erwähnt.A statically mounted sanding roller wears unevenly, as the same parts of the sanding surface repeatedly grind over the surface of the workpieces. In the German Offenlegungsschrift 1 502 538 It is therefore proposed to reciprocate the sanding roll transversely to to cause a uniform wear of the sanding roller. As a possible mechanism for generating the reciprocating motion of the grinding roller in the transverse direction, a crank rod drive is mentioned.

Es liegt nahe, für die Hin- und Her-Bewegung der Schleifwalze in axialer Richtung einen vom Hauptantrieb unabhängigen zweiten Antrieb vorzusehen. Dies hat den Vorteil, dass die Drehzahl der Schleifwalze und die Frequenz der axialen Hin- und Her-Bewegung völlig unabhängig voneinander gewählt oder sogar im laufenden Betrieb eingestellt werden können. Allerdings wird die Maschine durch das Vorsehen eines zweiten separaten Antriebs für die Oszillation der Schleifwalze erheblich komplizierter und damit nicht nur teurer, sondern auch weniger zuverlässig im Betrieb.It makes sense to provide for the reciprocation of the grinding roller in the axial direction independent of the main drive second drive. This has the advantage that the speed of the grinding roller and the frequency of the axial reciprocating motion can be selected completely independently or even adjusted during operation. However, by providing a second separate drive for the oscillation of the sanding drum, the machine becomes considerably more complicated and thus not only more expensive, but also less reliable in operation.

Aufgabe der Erfindung ist somit die Schaffung einer Vorrichtung zum Schleifen und Entgraten eines flächigen Werkstücks mit einer Schleifwalze, die außer der Rotationsbewegung eine axiale Hin- und Her-Bewegung ausführt, ohne dass ein zweiter Motor vorgesehen werden muss.The object of the invention is therefore to provide a device for grinding and deburring a flat workpiece with a grinding roller, which performs an axial reciprocating motion in addition to the rotational movement without a second motor must be provided.

Diese Aufgabe wird bei einer Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1 dadurch gelöst, dass die Schleifwalze auf der Antriebswelle axial verschieblich gelagert ist, und dass mit dem Antriebsmotor ein Verschiebegetriebe gekoppelt ist, welches die oszillierende Hin- und Her-Bewegung der Schleifwalze auf der Antriebswelle erzeugt.This object is achieved in a device according to the preamble of patent claim 1, characterized in that the grinding roller is mounted axially displaceably on the drive shaft, and that a displacement gear is coupled to the drive motor, which oscillates the reciprocating motion of the grinding roller on the drive shaft generated.

Bei der erfindungsgemäßen Vorrichtung sitzt die Schleifwalze koaxial auf der Antriebswelle, wobei die Schleifwalze mit der Antriebswelle drehfest verbunden ist. Gleichzeitig ist die Schleifwalze auf der Antriebswelle axial verschieblich gelagert, so dass sie eine Hin- und Her-Bewegung gegenüber der ortsfesten Antriebswelle ausführen kann. Der Antriebsmotor treibt die Schleifwalze direkt an und ist gleichzeitig mit dem Verschiebegetriebe gekoppelt, das die oszillierende Bewegung der Schleifwalze in axialer Richtung erzeugt. Auf diese Weise genügt ein einziger Antriebsmotor, um sowohl die Rotationsbewegung der Schleifwalze als auch deren Hin- und Her-Bewegung in axialer Richtung zu erzeugen.In the apparatus according to the invention, the grinding roller is seated coaxially on the drive shaft, wherein the grinding roller is rotatably connected to the drive shaft. At the same time the grinding roller is mounted axially displaceably on the drive shaft, so that it can perform a reciprocating movement relative to the stationary drive shaft. The drive motor drives the grinding roller directly and at the same time is coupled to the shifting gear, which generates the oscillating movement of the grinding roller in the axial direction. In this way, a single drive motor is sufficient to both the rotational movement the grinding roller as well as their reciprocating motion to generate in the axial direction.

Das erfindungsgemäß zwischen dem Antriebsmotor und der Antriebswelle der Schleifwalze angeordnete Verschiebegetriebe ist vorzugsweise als Kurvengetriebe ausgebildet und umfasst einen auf der Antriebswelle der Schleifwalze drehbar gelagerten Steuerzylinder mit einer Nutkurve sowie einen an der Schleifwalze angeordneten Kurvenreiter, der die Nutkurve des Steuerzylinders abfährt. Die seitliche Auslenkung der Nutkurve bestimmt dabei die axiale Verlagerung der Schleifwalze auf der Antriebswelle.The sliding gear arranged according to the invention between the drive motor and the drive shaft of the grinding roller is preferably designed as a cam gear and comprises a rotatably mounted on the drive shaft of the grinding roller control cylinder with a cam groove and arranged on the grinding roller cam rider, which moves off the cam groove of the control cylinder. The lateral deflection of the cam groove determines the axial displacement of the grinding roller on the drive shaft.

Die Nutkurve kann z. B. sinusförmig ausgebildet sein. Bevorzugt durchfährt der Kurvenreiter eine vollständige Sinuskurve pro Umdrehung des Steuerzylinders, so dass nach einer vollständigen Umdrehung des Steuerzylinders die Schleifwalze genau eine Hin- und Her-Bewegung in axialer Richtung ausgeführt hat. Denkbar ist natürlich auch, dass die Nutkurve mehrere Minima und Maxima hat, so dass die Oszillationsfrequenz ein Mehrfaches der Umdrehungszahl des Steuerzylinders beträgt.The groove curve can z. B. be formed sinusoidal. Preferably, the cam rider passes through a complete sinusoid per revolution of the control cylinder, so that after a complete revolution of the control cylinder, the grinding roller has performed exactly one back and forth movement in the axial direction. It is also conceivable, of course, that the groove curve has several minima and maxima, so that the oscillation frequency is a multiple of the number of revolutions of the control cylinder.

Bei einer bevorzugten Ausführung der erfindungsgemäßen Vorrichtung hat die Schleifwalze an ihrer einen Stirnseite eine zylindrische Ausnehmung, in welcher der Steuerzylinder koaxial angeordnet ist. Auf diese Weise lässt sich das Kurvengetriebe in die Schleifwalze integrieren, ohne dass zusätzlicher Platz beansprucht würde.In a preferred embodiment of the device according to the invention, the grinding roller has at its one end face a cylindrical recess in which the control cylinder is arranged coaxially. In this way, the cam gear can be integrated into the grinding roller, without additional space would be claimed.

Die Schleifwalze ist bevorzugt als Hohlzylinder ausgebildet, an dessen Innenwand mindestens ein axialer Führungsschlitz angeordnet ist. Die Antriebswelle trägt wenigstens eine korrespondierende Kurvenrolle, die in den Führungsschlitz des Hohlzylinders eingreift. Vorteilhaft ist zudem zwischen der Antriebswelle und der Schleifwalze wenigstens ein Gleitlager angeordnet. Zweckmäßig ist es, zumindest zwei Führungsschlitze und korrespondierende Kurvenrollen vorzusehen, die jeweils im Bereich des rechten bzw. linken Endes der Schleifwalze angeordnet sind. Kurvenrollen und axiale Führungsschlitze bilden die notwendige drehfeste Verbindung zwischen Antriebswelle und Schleifwalze und ermöglichen gleichzeitig die Verschieblichkeit der Schleifwalze auf der Antriebswelle in axialer Richtung, um die oszillierende Hin- und Her-Bewegung der Schleifwalze zu erlauben.The grinding roller is preferably designed as a hollow cylinder, on whose inner wall at least one axial guide slot is arranged. The drive shaft carries at least one corresponding cam roller which engages in the guide slot of the hollow cylinder. Advantageously, at least one slide bearing is also arranged between the drive shaft and the grinding roller. It is expedient to provide at least two guide slots and corresponding cam rollers, which are each arranged in the region of the right or left end of the sanding roller. Cam rollers and axial guide slots form the necessary non-rotatable connection between drive shaft and grinding roller and at the same time allow the sliding of the grinding roller on the drive shaft in the axial direction to allow the oscillating reciprocating motion of the grinding roller.

Bei einer besonders bevorzugten Ausführung der erfindungsgemäßen Vorrichtung treibt der Antriebsmotor über einen ersten Riemenantrieb die Antriebswelle der Schleifwalze an und über einen zweiten Riemenantrieb das Verschiebegetriebe, das vorzugsweise als Kurvengetriebe ausgebildet ist. Zwei mit dem Antriebsmotor gekoppelte Riemenantriebe erlauben die Wahl unterschiedlicher Übersetzungen für den ersten und den zweiten Riemenantrieb. Auf diese Weise lässt sich die Frequenz der oszillierenden Hin- und Her-Bewegung der Schleifwalze auf der Antriebswelle unabhängig von der Umdrehungsgeschwindigkeit der Schleifwalze um ihre Achse einstellen. Bevorzugt ist der zweite Riemenantrieb, der das Verschiebegetriebe antreibt, mit dem ersten Riemenantrieb, der die Antriebswelle der Schleifwalze antreibt, über eine Verbindungswelle gekoppelt. Damit stellt der erste Riemenantrieb den Primärantrieb für die Schleifwalze dar und der zweite, über die Verbindungswelle angekoppelte Riemenantrieb einen Sekundärantrieb für die Hinund Her-Bewegung. Es ist allerdings auch möglich, zwei unabhängige Riemenantriebe vorzusehen, die jeweils direkt die Rotationsbewegung des Antriebsmotors auf die Schleifwalze bzw. das Verschiebegetriebe übertragen.In a particularly preferred embodiment of the device according to the invention, the drive motor drives the drive shaft of the grinding roller via a first belt drive and, via a second belt drive, the displacement gear, which is preferably designed as a cam gear. Two belt drives coupled to the drive motor allow the selection of different ratios for the first and second belt drives. In this way, the frequency of the oscillating reciprocating motion of the grinding roller on the drive shaft can be adjusted independently of the rotational speed of the grinding roller about its axis. Preferably, the second belt drive, which drives the shift gear, is coupled to the first belt drive, which drives the drive shaft of the grinding roller, via a connecting shaft. Thus, the first belt drive is the primary drive for the grinding roller and the second, coupled via the connecting shaft belt drive a secondary drive for the back-and-forth motion. However, it is also possible to provide two independent belt drives, which each directly transmit the rotational movement of the drive motor to the sanding roller or the sliding gear.

Zweckmäßig umfasst der erste Riemenantrieb eine erste Riemenscheibe, die auf der Antriebswelle der Schleifwalze sitzt, und umfasst der zweite Riemenantrieb eine zweite Riemenscheibe, die mit dem Steuerzylinder verbunden ist. Ein derart konstruierter doppelter Riemenantrieb erlaubt es auf einfache Weise, die Antriebswelle der Schleifwalze und den auf der Antriebswelle drehbar gelagerten Steuerzylinder mit verschiedenen Drehzahlen rotieren zu lassen, indem die beiden Riemenantriebe unterschiedliche Übersetzungsverhältnisse haben. Auch nachträglich lassen sich die Übersetzungsverhältnisse leicht verändern. Zum Beispiel kann bei unveränderten Drehzahlen des Antriebsmotors und der Schleifwalze die Frequenz der oszillierenden axialen Bewegung der Schleifwalze veränderten Bedingungen angepasst werden, z. B. allein durch den Austausch der mit dem Steuerzylinder verbundenen Riemenscheibe.Suitably, the first belt drive comprises a first pulley seated on the drive shaft of the sanding drum, and the second belt drive comprises a second pulley connected to the control cylinder. Such a constructed double belt drive allows to easily rotate the drive shaft of the grinding roller and rotatably mounted on the drive shaft control cylinder at different speeds by the two belt drives have different gear ratios. Even subsequently, the transmission ratios can be easily changed. For example, at unchanged speeds of the drive motor and the grinding roller, the frequency of the oscillating axial movement of the Grinding roller to be changed conditions, z. B. solely by the replacement of the pulley connected to the control cylinder.

Eine Lagerung der Schleifwalzenwelle im Maschinengestell derart, dass das eine, z. B. rechte Ende der Antriebswelle in einem abklappbaren Wälzlager gelagert ist, bietet den Vorteil, dass die zylindrische Schleifwalze in axialer Richtung von der Antriebswelle bzw. der Schleifbelag von der Schleifwalze abgezogen werden kann, was den Austausch sehr einfach macht. In diesem Fall ist es zweckmäßig, die beiden Riemenantriebe für die Schleifwalze bzw. den Steuerzylinder nebeneinander an dem Ende der Antriebswelle anzuordnen, das der abklappbaren Lagerstelle gegenüber liegt. Auch die Riemenantriebe bilden dann kein Hindernis für einen Austausch des Schleifbelags oder auch der kompletten Schleifwalze durch Abziehen in axialer Richtung von den Riemenantrieben weg.A storage of the grinding roller shaft in the machine frame such that the one, z. B. right end of the drive shaft is mounted in a hinged bearing, has the advantage that the cylindrical grinding roller can be deducted in the axial direction of the drive shaft or the abrasive coating of the sanding roller, which makes the exchange very easy. In this case, it is expedient to arrange the two belt drives for the grinding roller or the control cylinder next to each other at the end of the drive shaft, which lies opposite the hinged bearing point. The belt drives then form no obstacle to an exchange of the abrasive coating or the entire grinding roller by pulling in the axial direction of the belt drives away.

An embodiment of the invention will be explained below with reference to the accompanying drawings. Show it:
FIG. 1
a deburring machine in a highly simplified vertical section;
FIG. 2
a detail enlargement of the area A of FIG. 1 ,

In den Abbildungen sind nur die wesentlichen Teile der Entgratmaschine zu sehen, soweit sie für das Verständnis der Erfindung notwendig sind.In the figures, only the essential parts of the deburring machine are to be seen, as far as they are necessary for the understanding of the invention.

In einem Maschinenständer 1 ist eine Schleifwalze 2 um ihre horizontale Achse drehbar gelagert. Die Schleifwalze 2 sitzt koaxial auf einer Antriebswelle 3, welche durch zwei Wälzlager 4a, 4b im Maschinenständer 1 drehbar gelagert ist. Die beiden Wälzlager 4a, 4b sind mit einigem Abstand voneinander angeordnet. Ein drittes, hier nicht dargestelltes Wälzlager befindet sich am freien (in Figur 1 rechten) Ende der Antriebswelle 3, wobei dieses dritte Wälzlager von der Antriebswelle 3 durch Abklappen gelöst werden kann, so dass die Schleifwalze 2, wie hier dargestellt, temporär frei fliegend gelagert ist.In a machine stand 1, a grinding roller 2 is rotatably supported about its horizontal axis. The grinding roller 2 is seated coaxially on a drive shaft 3, which is rotatably supported by two roller bearings 4 a, 4 b in the machine frame 1. The two rolling bearings 4a, 4b are arranged at some distance from each other. A third, not shown here rolling bearing is located on the free (in FIG. 1 right) end of the drive shaft 3, said third roller bearing can be solved by the drive shaft 3 by folding down, so that the grinding roller 2, as shown here, is stored temporarily free-floating.

Auf der zylindrischen Außenseite der Schleifwalze 2 ist ein Schleifbelag 5 zur abrasiven Bearbeitung eines flächigen Werkstücks 6 angeordnet. Der Schleifbelag 5 ist hier als endloser zylindrischer Schlauch ausgeführt und kann vom freien Ende der Antriebswelle 3 her in axialer Richtung auf die Schleifwalze 2 aufgezogen und in Gegenrichtung abgezogen werden. Zur Entfernung von Graten auf der im Wesentlichen ebenen Oberseite des Werkstücks 6 wird dieses in horizontaler Richtung unter der sich drehenden Schleifwalze 2 vorbeibewegt.On the cylindrical outer side of the grinding roller 2, an abrasive coating 5 for abrasive machining of a flat workpiece 6 is arranged. The abrasive coating 5 is designed here as an endless cylindrical tube and can be raised from the free end of the drive shaft 3 ago in the axial direction on the sanding roller 2 and withdrawn in the opposite direction. To remove burrs on the substantially planar upper side of the workpiece 6, this is moved in the horizontal direction below the rotating grinding roller 2.

Angetrieben wird die Schleifwalze 2 von einem Antriebsmotor 7, einem starken Elektromotor. Dessen Motorwelle 8 ist ebenfalls horizontal im Maschinenständer 1 gelagert. Über einen ersten primären Riemenantrieb 9 treibt der Antriebsmotor 7 die Antriebswelle der Schleifwalze 2 an. Der Riemenantrieb 9 umfasst eine untere Riemenscheibe 10, eine obere Riemenscheibe 11, die auf der Antriebswelle 3 der Schleifwalze 2 sitzt, sowie einen über die Riemenscheiben 10, 11 geführten Treibriemen 12.The grinding roller 2 is driven by a drive motor 7, a strong electric motor. Whose motor shaft 8 is also mounted horizontally in the machine frame 1. The drive motor 7 drives the drive shaft of the grinding roller 2 via a first primary belt drive 9. The belt drive 9 comprises a lower pulley 10, an upper pulley 11, which sits on the drive shaft 3 of the grinding roller 2, and a drive belt 12 guided over the pulleys 10, 11.

Die Antriebswelle 3 ist mit der Schleifwalze 2 drehfest verbunden. Gleichzeitig ist die Schleifwalze 2 auf der Antriebswelle 3 in axialer Richtung verschieblich gelagert. Realisiert wird dies durch zwei axiale Führungsschlitze 13a, 13b an der zylindrischen Innenseite der Schleifwalze 2, welche als Hohlzylinder ausgebildet ist, und zwei korrespondierende Kurvenrollen 14a, 14b, die auf der Antriebswelle 3 sitzen und in die Führungsschlitze 13a, 13b eingreifen. Zwischen Antriebswelle 3 und Schleifwalze 2 ist ein Gleitlager 15 angeordnet, so dass die Schleifwalze 2 leicht auf der Antriebswelle 3 axial hin- und hergleiten kann, soweit dies die relative Bewegung der Kurvenrollen 14a, 14b in den Führungsschlitzen 13a, 13b zulässt. Die Kurvenrollen 14a, 14b haben die Funktion von Mitnehmern, welche die Rotationsbewegung der Antriebswelle 3 auf die Schleifwalze 2 übertragen.The drive shaft 3 is rotatably connected to the grinding roller 2. At the same time, the grinding roller 2 is displaceably mounted on the drive shaft 3 in the axial direction. This is realized by two axial guide slots 13a, 13b on the cylindrical inside of the grinding roller 2, which is designed as a hollow cylinder, and two corresponding cam rollers 14a, 14b, which sit on the drive shaft 3 and engage in the guide slots 13a, 13b. Between the drive shaft 3 and the grinding roller 2, a sliding bearing 15 is arranged, so that the grinding roller 2 can easily slide back and forth axially on the drive shaft 3, as far as this permits the relative movement of the cam rollers 14a, 14b in the guide slots 13a, 13b. The cam rollers 14a, 14b have the function of drivers, which transmit the rotational movement of the drive shaft 3 to the grinding roller 2.

Der Antriebsmotor 7 lässt nicht nur die Schleifwalze 2 rotieren, sondern bewirkt auch eine oszillierende Hin- und Her-Bewegung der Schleifwalze 2 gegenüber der Antriebswelle 3. Hierzu ist ein zweiter sekundärer Riemenantrieb 16 vorgesehen. Dieser Riemenantrieb 16 umfasst eine obere Riemenscheibe 17 und eine untere Riemenscheibe 18, über welche ein Treibriemen 19 läuft. Eine Verbindungswelle 20 ist horizontal und damit parallel zur Antriebswelle 3 und zur Motorwelle 8 im Maschinenständer 1 drehbar gelagert. Die untere Riemenscheibe 18 sitzt auf dem einen (in Figur 1 rechten) Ende der Verbindungswelle 20. Auf dem gegenüberliegenden Ende der Verbindungswelle 20 sitzt eine weitere Riemenscheibe 21 ungefähr in der Mitte zwischen der unteren Riemenscheibe 10 und der oberen Riemenscheibe 11 des primären Riemenantriebs 9, wobei diese drei Riemenscheiben 10, 11, 21 in einer Ebene liegen. Der Treibriemen 12 des primären Riemenantriebs 9 ist über die mittlere Riemenscheibe 21 geführt und überträgt so die Rotationsbewegung des Antriebsmotors 7 auf die Verbindungswelle 20 und den angekoppelten sekundären Riemenantrieb 16.The drive motor 7 not only rotates the grinding roller 2, but also causes oscillating reciprocation of the grinding roller 2 with respect to the drive shaft 3. For this purpose, a second secondary belt drive 16 provided. This belt drive 16 comprises an upper pulley 17 and a lower pulley 18, over which a drive belt 19 passes. A connecting shaft 20 is horizontal and thus rotatably mounted parallel to the drive shaft 3 and the motor shaft 8 in the machine frame 1. The lower pulley 18 is seated on one (in FIG. 1 On the opposite end of the connecting shaft 20 is another pulley 21 located approximately midway between the lower pulley 10 and the upper pulley 11 of the primary belt drive 9, these three pulleys 10, 11, 21 in one plane lie. The drive belt 12 of the primary belt drive 9 is guided over the middle pulley 21 and thus transmits the rotational movement of the drive motor 7 to the connecting shaft 20 and the coupled secondary belt drive 16.

Die Schleifwalze 2 hat an ihrer dem freien Ende gegenüberliegenden (in Figur 1 linken) Stirnseite eine große zylindrische Ausnehmung. Ein ebenfalls zylindrisch ausgebildeter Steuerzylinder 23 sitzt nahezu vollständig in der Ausnehmung 22 und ist mittels Wälzlagern 24a, 24b auf der Antriebswelle 3 der Schleifwalze 2 gelagert, so dass er sich frei auf der Antriebswelle 3 drehen kann. In die Mantelfläche des Steuerzylinders 23 ist eine Nutkurve 25 mit näherungsweise rechteckigem Querschnitt eingearbeitet. Wie insbesondere in der vergrößerten Darstellung von Figur 2 zu sehen, ist ein korrespondierender Kurvenreiter 26 an einer zylindrischen Innenwand der Schleifwalze 2 angeordnet und greift in die Nutkurve 25 des Steuerzylinders 23 ein. Der Kurvenreiter 26 ist als Kurvenrolle ausgebildet, um die Reibung zwischen Nutkurve 25 und Kurvenreiter 26 zu verringern.The grinding roller 2 has at its free end opposite (in FIG. 1 left) front side a large cylindrical recess. A likewise cylindrical trained control cylinder 23 sits almost completely in the recess 22 and is mounted by means of rolling bearings 24a, 24b on the drive shaft 3 of the grinding roller 2, so that it can rotate freely on the drive shaft 3. In the lateral surface of the control cylinder 23, a groove curve 25 is incorporated with approximately rectangular cross section. As in particular in the enlarged view of FIG. 2 can be seen, a corresponding cam follower 26 is disposed on a cylindrical inner wall of the grinding roller 2 and engages in the cam groove 25 of the control cylinder 23 a. The cam follower 26 is designed as a cam roller in order to reduce the friction between the cam groove 25 and cam follower 26.

An der freien (in Figuren 1, 2 linken) Stirnseite des Steuerzylinders 23 ist die obere Riemenscheibe 17 des sekundären Riemenantriebs 16 angeflanscht. Somit treibt der Antriebsmotor 7 nicht nur die Schleifwalze 2 an, sondern versetzt über den sekundären Riemenantrieb 16 auch den Steuerzylinder 23 in eine Rotationsbewegung koaxial zur Schleifwalze 2 bzw. deren Antriebswelle 3. Die Geschwindigkeit, mit der sich der Steuerzylinder 23 auf der Antriebswelle 3 dreht, ist allerdings nicht dieselbe wie die Geschwindigkeit, mit der sich die Schleifwalze 2 um ihre Achse dreht. Da die beiden Riemenantriebe 9 und 16 unterschiedliche Übersetzungsverhältnisse haben, rotieren die Antriebswelle 3 bzw. die damit drehfest verbundene Schleifwalze 2 und der Steuerzylinder 23 mit verschiedenen Drehzahlen.At the free (in FIGS. 1 . 2 left) end face of the control cylinder 23, the upper pulley 17 of the secondary belt drive 16 is flanged. Thus, the drive motor 7 drives not only the grinding roller 2, but offset via the secondary belt drive 16 and the control cylinder 23 in a rotational movement coaxial with the grinding roller 2 and the drive shaft 3. The speed at which the control cylinder 23 on the drive shaft 3, however, is not the same as the speed at which the grinding roller 2 rotates about its axis. Since the two belt drives 9 and 16 have different transmission ratios, the drive shaft 3 or the rotatably connected grinding roller 2 and the control cylinder 23 rotate at different speeds.

Die Nutkurve 25 verläuft sinusförmig auf der Mantelfläche des Steuerzylinders 23. Über eine volle Umdrehung betrachtet, wandert die Nutkurve 25 zwischen dem rechten und dem linken Rand des Steuerzylinders 23 hin- und her, wie in Figur 2 durch einen Doppelpfeil angedeutet. Der Kurvenreiter 26 folgt dieser oszillierenden Bewegung in axialer Richtung und überträgt dadurch die Auslenkung der Nutkurve 25 auf die Schleifwalze 2, so dass diese sich nicht nur um ihre Achse dreht, sondern gleichzeitig eine oszillierende Hin- und Her-Bewegung in axialer Richtung ausführt.The groove cam 25 runs sinusoidally on the lateral surface of the control cylinder 23. Viewed over a full revolution, the cam groove 25 moves back and forth between the right and left edges of the control cylinder 23, as in FIG. 2 indicated by a double arrow. The cam follower 26 follows this oscillating movement in the axial direction and thereby transmits the deflection of the cam groove 25 on the grinding roller 2, so that it not only rotates about its axis, but at the same time performs an oscillating reciprocating motion in the axial direction.

Pro Umdrehung des Steuerzylinders 23 durchfährt der Kurvenreiter 26 eine volle Periode der sinusförmigen Nutkurve 25. Die Anzahl der Hin- und HerBewegungen der Schleifwalze 2 hängt von der Rotationsgeschwindigkeit des Steuerzylinders 23 im Verhältnis zur Rotationsgeschwindigkeit der Schleifwalze 2 ab. Dabei läuft die Schleifwalze 2 erheblich schneller um als der Steuerzylinder 23. Beispielsweise beträgt die Geschwindigkeit der Schleifwalze 1.000 U/min, während die Oszillationsfrequenz 2/sec beträgt. Durch Wahl der Übersetzungsverhältnisse der beiden Riemenantriebe 9 und 16 und insbesondere das Verhältnis der Durchmesser der Riemenscheiben 17, 18 des sekundären Riemenantriebs 16 lässt sich die Oszillationsfrequenz sehr leicht einstellen.Per revolution of the control cylinder 23 of the cam follower 26 passes through a full period of the sinusoidal groove curve 25. The number of reciprocating movements of the grinding roller 2 depends on the rotational speed of the control cylinder 23 in relation to the rotational speed of the grinding roller 2 from. In this case, the grinding roller 2 rotates much faster than the control cylinder 23. For example, the speed of the grinding roller is 1,000 rpm, while the oscillation frequency is 2 / sec. By choosing the gear ratios of the two belt drives 9 and 16 and in particular the ratio of the diameter of the pulleys 17, 18 of the secondary belt drive 16, the oscillation frequency can be adjusted very easily.
