Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Lageroberflächen eines Lagers an einem rotationssymmetrischen Werkstück, mit einer Radiallagerfläche und zwei sich an gegenüberliegenden, axial beabstandeten Enden der Radiallagerfläche von dieser radial erstreckenden Anlaufbünden sowie je einem Einstich an den axialen Enden der Radiallagerfläche am Übergang der Radiallagerfläche zu den Anlaufbünden, insbesondere zum Herstellen einer Lageroberfläche eines Hublagers einer Kurbelwelle für eine Brennkraftmaschine, insbesondere eines Kraftfahrzeugs. Die Erfindung betrifft ferner ein Fräswerkzeug zum Ausführen eines zweiten Bearbeitungsschrittes des erfindungsgemäßen Verfahrens, gemäß dem Oberbegriff des Anspruchs 3.The The invention relates to a method for producing bearing surfaces Bearing on a rotationally symmetrical workpiece, with a radial bearing surface and two on opposite, axially spaced ends of the radial bearing surface of this radially extending start frets as well as a puncture at the axial ends of the radial bearing surface at the transition the radial bearing surface to the startup collars, in particular for producing a bearing surface of a pin bearing of a crankshaft for an internal combustion engine, especially a motor vehicle. The invention further relates to a milling tool to run a second processing step of the method according to the invention, according to the preamble of claim 3.

der Herstellung beispielsweise einer Kurbelwelle für eine Brennkraftmaschine
ist es aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und ein Fräswerkzeug der obengenannten Art bzgl. Oberflächengüte der hergestellten Lageroberflächen, Kosten und Betriebssicherheit zu verbessern.The The invention is based on the object of a method and a milling tool of the type mentioned above with regard to surface quality of the bearing surfaces produced, costs and improve operational safety.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren der o.g. Art mit den in Anspruch 1 angegebenen Verfahrensschritten und durch ein Fräswerkzeug der o.g. Art mit den in Anspruch 3 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This The object is achieved by a Procedure of the above Type with the process steps specified in claim 1 and through a milling tool the above Type solved with the features characterized in claim 3. advantageous Embodiments of the invention are specified in the dependent claims.
Bei einem Verfahren der o.g. Art sind erfindungsgemäß folgende Schritte vorgesehen: In einem ersten Bearbeitungsschritt wird aus dem Werkstück mit einem ersten Fräswerkzeug die Lageroberfläche der Radiallagerfläche vollständig bis zu einem Schleifmaß und die Lageroberfläche der Anlaufbünde bis zu einem vorbestimmten radialen Abstand von der Radiallagerfläche bis zu einem Schleifmaß heraus gearbeitet und in einem zweiten Bearbeitungsschritt werden mit einem zweiten Fräswerkzeug die jeweiligen Lageroberflächen der Anlaufbünde auch im Bereich des vorbestimmten radialen Abstandes von der Radiallagerfläche vollständig bis zum Schleifmaß fertig bearbeitet und gleichzeitig aus dem Werkstück die Einstiche heraus gearbeitet.at a procedure of the above According to the invention, the following steps are provided: In a first machining step, the workpiece is turned into a first milling tool the bearing surface of the Radial bearing surface Completely up to a grinding dimension and the bearing surface the startup collars up to a predetermined radial distance from the radial bearing surface to a grinding measure worked and in a second processing step with a second milling tool the respective bearing surfaces the startup collars also completely in the range of the predetermined radial distance from the radial bearing surface ready to measure processed and at the same time worked the recesses out of the workpiece.
Dies hat den Vorteil, daß eine Verbesserung der Oberflächenqualität am Anlaufbund bei gleichzeitig verbesserter Standzeit der Bearbeitungswerkzeuge und damit reduzierten Herstellungskosten erzielt wird.This has the advantage that a Improvement of the surface quality on the start collar with improved tool life at the same time and thus reduced manufacturing costs.
Zweckmäßigerweise werden Wendeschneidplatten des zweiten Fräswerkzeuges mittels einer Feineinstellung auf eine Abweichung relativ zueinander im Bereich von μm eingestellt.Conveniently, become indexable inserts of the second milling tool by means of a fine adjustment set to a deviation relative to each other in the range of μm.
Bei einem Fräswerkzeug der o.g. Art ist es erfindungsgemäß vorgesehen, daß jede Aufnahme eine Verstellvorrichtung für die dieser Aufnahme zugeordnete Schneidplatte in axialer Richtung bzgl. des Rades aufweist.at a milling tool the above Art is provided according to the invention that each recording is a Adjustment device for the insert assigned to this receptacle in the axial direction with respect to the wheel.
Dies hat den Vorteil, daß für die Bearbeitung im zweiten Bearbeitungsschritt eine Feineinstellung der Schneidplatten möglich ist. Zusätzlich wird das Bearbeitungswerkzeug im zweiten Bearbeitungsschritt nur noch seitlich und durch die Feineinstellung gleichmäßiger belastet, was eine höhere Standzeit mit entsprechend reduzierten Kosten aufgrund gleichmäßiger Abnutzung der Schneidplatten zur Folge hat.This has the advantage that for processing in second processing step a fine adjustment of the inserts possible is. additionally the editing tool is only in the second editing step evenly loaded laterally and by the fine adjustment, what a higher Service life with correspondingly reduced costs due to even wear the result of cutting inserts.
Zweckmäßigerweise ist die Position jeder Schneidplatte in axialer Richtung bzgl. des Rades mittels der Verstellvorrichtung im μm-Bereich einstellbar.Conveniently, is the position of each insert in the axial direction with respect to the Wheel adjustable in the μm range using the adjustment device.
Weitere Merkmale, Vorteile und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie aus der nachstehenden Beschreibung der Erfindung anhand der beigefügten Zeichnungen. Diese zeigen inFurther Features, advantages and advantageous embodiments of the invention result from the dependent claims and from the following description of the invention with reference to the attached Drawings. These show in
