Abstract
Description
Die Erfindung bezieht sich auf ein Festwalzgerät einer Festwalzmaschine für Kurbelwellen, das in Scherenbauweise ausgeführt ist und bei dem zwei schwenkbare Scherenarme einander gegenüberliegend jeweils einen Festwalzrollenkopf bzw. einen Stützrollenkopf tragen, wobei der Stützrollenkopf mit zwei achsparallel angeordneten Stützrollen versehen ist, deren Drehachsen in einer gemeinsamen Ebene liegen, mit einer Antriebseinrichtung, die die Schließ- und Öffnungsbewegung des Festwalzgerätes sowie die Festwalzkraft erzeugt.The invention relates to a deep rolling device Deep rolling machine for crankshafts, the scissors construction is executed and in which two pivotable scissor arms one opposite each other Wear a deep rolling head or a support roller head, wherein the support roller head with two paraxial arranged support rollers is provided, whose axes of rotation lie in a common plane, with one Drive device, the closing and Opening movement of the deep rolling device and the Deep rolling force generated.
Festwalzgeräte der vorgenannten Art sind bekannt durch die deutsche Patentschrift DE 197 22 308 C1, die eine Festwalzmaschine für Kurbelwellen offenbart.Deep rolling devices of the aforementioned type are known by German Patent DE 197 22 308 C1, a Deep rolling machine for crankshafts disclosed.
Bei einer solchen Festwalzmaschine kann jedem Haupt- und Pleuellagerzapfen einer Kurbelwelle je ein Festwalzgerät zugeordnet werdén.In such a deep rolling machine can each main and Pleuellagerzapfen a crankshaft per a deep rolling mill be assigned.
Die Konstruktion der Festwalzmaschine ist so ausgelegt, dass beim Schließen eines jeden Festwalzgerätes zunächst die Stützrollen des Stützrollenkopfes und danach die Festwalzrollen des Festwalzrollenkopfes an einen Hauptoder Pleuellagerzapfen angedrückt werden.The design of the deep rolling machine is designed to that when closing each deep rolling machine first the support rollers of the support roller head and then the Deep rolling rollers of the deep rolling roller head to a main or Pleuellagerzapfen be pressed down.
Dabei führen der Stützrollenkopf und der Festwalzrollenkopf nacheinander je eine Schwenkbewegung aus. This lead the support roller head and the Rolling roller head successively each a pivoting movement out.
Die Schwenkbewegung des Stützrollen- und des Festwalzrollenkopfes im schließenden Sinne ist mit der Gefahr verbunden, dass es zu einer Kollision des Stützrollen- und des Festwalzrollenkopfes mit der Kurbelwelle im Bereich eines Ölbundes kommen kann, da die Freiräume zwischen dem Stützrollen- und dem Festwalzrollenkopf einerseits und den beiden Ölbunden eines Haupt- oder Pleuellagerzapfens andererseits knapp bemessen sind.The pivoting movement of the support roller and the Festwalzrollenkopfes in the closing sense is with the Danger that there is a collision of the Support roller and the deep rolling roller head with the Crankshaft can come in the area of an oil collar, as the Free spaces between the support roller and the Deep rolling head on the one hand and the two oil bundles of a main or connecting rod journal, on the other hand scarce are measured.
Der Erfindung liegt die Aufgabe zugrunde, ein Festwalzgerät der eingangs genannten Art so auszubilden, dass die Schwenkbewegung des Stützrollen- und des Festwalzrollenkopfes im schliessenden Sinne keine Kollision mit der Kurbelwelle im Bereich eines Ölbundes auslösen kann.The invention is based on the object Deep rolling machine of the type mentioned in the form of that the pivoting movement of the Stützrollen- and the Deep rolling roller head in the closing sense no Collision with the crankshaft in the area of an oil collar can trigger.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Stützrollenkopf wenigstens eine Axialführungsrolle aufweist, die in der Schwenkrichtung zum Schliessen des die Stützrollen tragenden Scherenarmes vor den Stützrollen angeordnet ist, deren Drehachse zur Drehachse der Kurbelwelle senkrecht steht und in einer Ebene liegt, welche mit der Ebene der Drehachsen der Stützrollen einen spitzen Winkel einschliesst, und deren Durchmesser größer als die Breite des Stützrollenkopfes und geringfügig kleiner als die Distanz der Ölbunde eines Haupt- oder Pleuellagerzapfens ist.According to the invention, this object is achieved in that the support roller head at least one Axialführungsrolle having in the pivoting direction for closing the the support rollers carrying scissor arm in front of the Support rollers is arranged, whose axis of rotation to the axis of rotation the crankshaft is vertical and lies in one plane, which with the plane of the axes of rotation of the support rollers a acute angle encloses, and whose diameter larger as the width of the support roller head and slightly smaller than the distance of the oil bundles of a major or Connecting rod journal is.
Durch die Erfindung wird beim Schließvorgang des Festwalzgeräts erreicht, dass im Falle des Anstoßens der Führungsrolle gegen einen Ölbund eine Ausrichtung des Festwalzgerätes in Achsrichtung der Kurbelwelle erfolgt. By the invention is during the closing of the Festwalzgeräts achieved that in case of abutment of the Leadership against an oil collar an alignment of the Hard rolling machine in the axial direction of the crankshaft.
Mit einer solchen Ausrichtung des Festwalzgerätes ist sichergestellt, dass auch die Schwenkbewegung des Festwalzrollenkopfes im schließenden Sinne zu keiner Kollision des Festwalzrollenkopfes mit der Kurbelwelle im Bereich eines Ölbundes führen kann.With such an orientation of the deep rolling machine is ensured that the pivoting movement of the Deep rolling roller head in the closing sense to none Collision of the deep rolling roller head with the crankshaft in Area of an oil covenant.
Für den Fall, dass der spitze Winkel zwischen der die Drehachse der Axialführungsrolle enthaltenden Ebene und der gemeinsamen Ebene, welche durch die Drehachsen der beiden Stützrollen gebildet wird 0° beträgt, hat die Axialführungsrolle einen Abstand von dieser gemeinsamen Ebene. Auch kann die Ausssenkontur der Axialführungsrolle neben der klassisch zylindrischen andere Formen aufweisen und z.B. ballig oder aus mehreren geometrischen Formen zusammengesetzt sein.In the event that the acute angle between the Rotary axis of the axial guide roller containing plane and the common plane, which through the axes of rotation of the two support rollers is formed is 0 °, the Axialführungsrolle a distance from this common Level. Also, the Ausssenkontur the Axialführungsrolle in addition to the classic cylindrical have other shapes and e.g. spherical or of several geometric shapes be composed.
Zum Bearbeiten von besonders breiten Wellenlagerzapfen können anstelle einer einzelnen mehrere Axialführungsrollen vorgesehen sein, die nebeneinander angeordnet sind und den Freiraum ausfüllen, der durch zwei benachbarte Ölbunde umschrieben wird. Üblich sind zwei Axialführungsrollen, deren äussere Breite so bemessen ist, dass beide Axialführungsrollen mit geringem seitlichen Spiel in den Freiraum zwischen den Ölbunden hineinpassen. Eine derartige Anordnung hat auch den Vorteil, dass die Axialführungsrollen verhältnismässig klein sind. Dadurch wird zugleich die seitliche Reibung zwischen den Axialführungsrollen und den Ölbunden verringert.For machining extra wide shaft journal can instead of a single several Axial guide rollers be provided, the side by side are arranged and fill in the space through two adjacent oil bundles is circumscribed. Are common two Axialführungsrollen whose outer width so is dimensioned that both Axialführungsrollen with low lateral play in the space between the oil bundles fit. Such an arrangement also has the Advantage that the Axialführungsrollen relatively are small. As a result, at the same time the lateral friction between the axial guide rollers and the oil straps reduced.
Im folgenden wird die Erfindung anhand von Zeichnungen, worin Ausführungsbeispiele schematisch dargestellt sind, näher beschrieben. In the following the invention with reference to drawings, wherein exemplary embodiments are shown schematically, described in more detail.

Erfindungsgegenstandes ausreicht.However, the present embodiment is on the

Dem Hauptlagerzapfen 5 ist ein Festwalzgerät 8
zugeordnet, das in Scherenbauweise mit zwei Scherenarmen
9, 10, einem Scherendrehpunkt 11, einer
Antriebseinrichtung 12, einem Festwalzrollenkopf 13 und
einem Stützrollenkopf 14 versehen ist. Infolge der
Scherenbauweise sind der Festwalzkopf 13 und der
Stützrollenkopf 14 einzeln in Richtung entlang der
Drehachse 4 nicht beweglich. Vielmehr sind sie nur in
bestimmten Ebenen einstellbar, welche der jeweiligen Lage
der zu bearbeitenden Hauptlagerzapfen 5 bzw.
Pleuellagerzapfen längs der Drehachse 4 der Kurbelwelle 3
entsprechen. Eine derartige Ebene ist beispielsweise in
der Fig. 3 dargestellt.The
Die Antriebseinrichtung 12 hat einen Verstellzylinder 15
und ein Kraftgerät 16.The
Der Verstellzylinder 15 erzeugt die Schließ- und
Öffnungsbewegung der vorstehend beschriebenen Schere des
Festwalzgerätes 8; das Kraftgerät 16 die Festwalzkraft.
Durch die Unterteilung der von den Zylindern 15 und 16
erzeugten Bewegungen wird eine besonders schmale Bauweise
des Festwalzgerätes 8 erhalten.The adjusting
Das Festwalzgerät 8 ist über einen Anlenkpunkt 17 an

angelenkt.The deep

Kolbenzylindereinheit 20. Durch Betätigung der Kolben-Zylindereinheit

Die Festwalzmaschine 1 ist so ausgelegt, dass beim
Schließen des Festwalzgerätes 8 zunächst die beiden
achsparallel angeordneten Stützrollen 21, 22 des
Stützrollenkopfes 14 und danach die beiden Festwalzrollen
23, 24 des Festwalzkopfes 13 an dem Hauptlagerzapfen 5
zur Anlage kommen.The deep rolling machine 1 is designed so that when
Close the deep
Hierbei führen, in der Ansicht der Fig. 1, der
Stützrollenkopf 14 eine Schwenkbewegung 35 im
Gegenuhrzeigersinne um den Anlenkpunkt 17 und der
Festwalzrollenkopf 13 eine Schwenkbewegung 36 im
Uhrzeigersinn um den Scherendrehpunkt 11 aus. Beide
Schwenkbewegungen 35 und 36 werden gleichzeitig
ausgeführt und an ihrem jeweiligen Ende wird die
Schliesstellung erreicht, wie sie in der Figur 2
dargestellt ist. Die Schliesstellung entspricht der
Arbeitsstellung des Festwalzgerätes 8.This lead, in the view of FIG. 1, the
Support roller head 14 a
Bei den Schwenkbewegungen 35 bzw. 36 des Stützrollen- 14
und des Festwalzrollenkopfes 13 im schließenden Sinne
wird eine Kollision mit einem der beiden Ölbunde 25, 26
des Hauptlagerzapfens 5 durch eine Axialführungsrolle 27
vermieden. Die Axialführungsrolle 27 ist unter einem
spitzen Winkel 37 zwischen 0 und 45° und in einer Ebene
38 angeordnet. Die Drehachse 41, um welche die
Axialführungsrolle 27 drehbar ist, liegt in der Ebene 38
und steht zur Drehachse 4 der Kurbelwelle 3 senkrecht
(Figur 4).In the
Die Ebene 38 schliesst - geometrisch gesehen - die
Drehachse 4 der Kurbelwelle 3 mit ein, d.h. die Ebene 38
kann um die Drehachse 4 pendeln. Ein Vergleich der
Figuren 3 und 5 zeigt diese Möglichkeit deutlich auf.
Beispielsweise in der Ansicht der Figur 3 fällt die Ebene
38 in die Schnittebene IV - IV, d.h. der spitze Winkel 37
beträgt 0° und die Axialführungsrolle 27 hat von der
Ebene 34, in welcher die beiden Achsen 32 und 33 liegen,
einen seitlichen Abstand s. In diesem speziellen Falle
verlaufen die beiden Ebenen 34 und 38 zueinander
parallel.The
In der Figur 5 hingegen ist die Axialführungsrolle 27
gegenüber der gemeinsamen Ebene 34 der beiden Achsen 32
und 33 der jeweiligen Stützrollen 21 und 22 unter einem
spitzen Winkel 37 geneigt, der grösser als 0° ist. Diese
Bauweise bedingt, dass beim Einschwenken des
Stützrollenkopfes 14 in die Schliesstellung in Richtung
der Schwenkbewegung 35, die Axialführungsrolle 27 den
beiden Stützrollen 21 und 22 voraus eilt. Dabei tritt die
Axialführungsrolle 25 vor den Stützrollen 21 und 22 in
den Freiraum ein, der durch die Distanz 29a der beiden
Ölbunde 25 und 26 am Hauptlagerzapfen umschrieben wird.
Auf diese Weise wird vermieden, dass eine der Stützrollen
21 oder 22 beim Schliessen des Festwalzgerätes 8 gegen
einen der Ölbunde 25 oder 26 anläuft.In contrast, in FIG. 5, the
Die Axialführungsrolle 27 kann unterschiedliche Formen
haben. In der Figur 3 hat sie beispielsweise eine
zylindrische Form. In der Figur 5 hat die
Axialführungsrolle 27 eine Mehrfachkontur, die sich aus
einem zylindrischen 39 und einem kegeligen Abschnitt 40
zusammensetzt. Daneben kann die Axialführungsrolle 27
auch ballig (nicht gezeigt) ausgestaltet sein. Bei
Lagerzapfen 5, die eine besonders grosse Breite 29a
haben, können anstelle einer einzelnen Axialführungsrolle
27 auch zwei Axialführungsrollen (nicht gezeigt)
nebeneinander angeordnet sein, wobei sich die eine an den
Ölbund 25 und die zweite an den Ölbund 26 anlegt. The
Aufgrund der Scherenbauweise des Festwalzgerätes 8
übernimmt die Axialführungsrolle 27 zugleich auch die
Führung der Festwalzrollenkopfes 13 in axialer Richtung.Due to the scissor construction of the
Der Durchmesser 28 der Axialführungsrolle 27 ist grösser
als die Breite 29 des Stützrollenkopfes und geringfügig
kleiner als die Distanz 29a der Ölbunde 25, 26 des
Hauptlagerzapfens 5.The
In der Schließstellung des Festwalzgeräts 8 (Figur 2)
sind für die beiden Freiräume 30, 31 zwischen den
