Abstract
Description
Die Erfindung betrifft einen Verstellring zum Verstellen der Schaufeln des VTG-Leitapparates von Abgasturboladern.The invention relates to an adjusting ring for adjusting the blades of the VTG diffuser of exhaust gas turbochargers.
Unter dem Begriff "VTG-Leitapparat" versteht man eine Anordnung, die dazu dient, Abgasturbolader mit einer variablen Turbinengeometrie zu versehen. Zur Verstellung dieser variablen Turbinengeometrie dient ein Verstellring der im Oberbegriff des Anspruches 1 angegebenen Art, der einen Lagerring zur Aufnahme von Lagerkörpern und einen Hebeleingriffsring aufweist. Der Hebeleingriffsring ist mit Nuten versehen, in die die Hebel der VTG-Schaufeln eingreifen.The term "VTG diffuser" is understood to mean an arrangement which serves to provide exhaust gas turbochargers with a variable turbine geometry. To adjust this variable turbine geometry is an adjusting ring specified in the preamble of claim 1, which has a bearing ring for receiving bearing bodies and a lever engagement ring. The lever engagement ring is provided with grooves in which the levers of the VTG blades engage.
Derartige bekannte Verstellringe sind als voll zerspante Bauteile aufgebaut, die üblicherweise in Dreh- oder Fräsvorgängen oder kombinierten Arbeitsgängen hergestellt werden. Hierzu wird aus einem Vollmaterial der Verstellring mit seinem Lagerring und einem Hebeleingriffsring als einstückiges Teil ausgebildet. Dies stellt jedoch ein relativ zeit- und kostenaufwendiges Herstellungsverfahren dar.Such known adjusting rings are constructed as fully machined components, which are usually produced in turning or milling operations or combined operations. For this purpose, the adjusting ring is formed with its bearing ring and a lever engaging ring as a one-piece part of a solid material. However, this represents a relatively time-consuming and costly production process.
Auch das Gießen eines kompletten Verstellringrohteils mit anschließender spanender Bearbeitung führt nicht zu deutlichen Kostenvorteilen.The casting of a complete Verstellringrohteils with subsequent machining does not lead to significant cost advantages.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Verstellring der im Oberbegriff des Anspruches 1 angegebenen Art zu schaffen, der auf einfache und kostengünstige Art und Weise herstellbar ist.It is therefore an object of the present invention to provide an adjusting ring specified in the preamble of claim 1 way, which can be produced in a simple and cost-effective manner.
Es ist ferner Aufgabe der Erfindung, ein Verfahren zur Herstellung eines derartigen Verstellringes zu schaffen.It is a further object of the invention to provide a method for producing such an adjusting ring.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1 bzw. des Anspruches 9.The solution of this object is achieved by the features of claim 1 and claim 9.
Erfindungsgemäß ist der Verstellring aus mehreren, zumindest zwei, separat hergestellten Einzelteilen gefertigt, die mittels einer geeigneten Verbindungseinrichtung miteinander verbunden werden. Die Einzelteile können hierbei durch Urform-(Feingießen oder Sintern), Umform- (Pressen) oder Trennverfahren, vorzugsweise Stanzen, komplett hergestellt werden oder erfordern eine geringe spanende Nachbearbeitung, wie Drehen oder Fräsen.According to the invention, the adjusting ring is made of several, at least two, separately manufactured individual parts, which are connected to one another by means of a suitable connecting device. The individual parts can in this case by Urform- (investment casting or sintering), forming (pressing) or separation processes, preferably stamping, be made completely or require a small machining finishing, such as turning or milling.
Die Einzelteile können aus verschiedenen Werkstoffen bestehen, die an die spezifische Funktion der Lagerung des Lagerrings bzw. Lagerabschnitts des Verstellringes und an die Führung der Schaufelhebel des Hebeleingriffsringes bzw. Hebeleingriffabschnittes angepasst sind.The items may consist of different materials, which are adapted to the specific function of the bearing of the bearing ring or bearing portion of the adjusting and the leadership of the blade lever of the lever engagement ring or lever engagement portion.
Ferner ergibt sich der Vorteil, dass der Lagerring und der Hebeleingriffsring hinsichtlich ihrer Geometrie auf einfache Art und Weise an die genannten Funktionen angepasst werden können.
So ist beispielsweise eine gezielte Härtung der Oberfläche gemäß der geforderten Eigenschaften möglich.Furthermore, there is the advantage that the bearing ring and the lever engagement ring can be adapted in terms of their geometry in a simple manner to the said functions.
For example, a specific hardening of the surface according to the required properties is possible.
Die Unteransprüche 2 bis 6 haben vorteilhafte Weiterbildungen des erfindungsgemäßen Verstellrings zum Inhalt.The dependent claims 2 to 6 have advantageous developments of the adjusting ring according to the invention to the content.
In den Ansprüchen 8 bis 11 ist ein erfindungsgemäßes Verfahren zur Herstellung eines zuvor erläuterten Verstellringes definiert.In claims 8 to 11, a method according to the invention for the production of a previously described adjusting ring is defined.
Demgemäß werden der Lagerring und der Hebeleingriffsring jeweils in einem separaten Herstellungsschritt als separate Einzelteile gefertigt.Accordingly, the bearing ring and the lever engagement ring are each made in a separate manufacturing step as separate items.
Danach werden die beiden Ringe durch eine geeignete Verbindungseinrichtung miteinander verbunden.Thereafter, the two rings are connected together by a suitable connecting device.
Als Verbindungseinrichtung können vom Prinzip her alle geeigneten stoff- oder formschlüssigen Verbindungen herangezogen werden.As a connecting device can be used in principle all suitable material or positive connections.
Besonders bevorzugt sind zur Verbindung des Lagerrings und des Herstellungsrings gemäß dem erfindungsgemäßen Verfahren jedoch Bördel- oder Umkantvorgänge sowie Schweißen oder Löten geeignet. ,However, crimping or edging operations as well as welding or soldering are particularly preferably suitable for connecting the bearing ring and the manufacturing ring according to the method according to the invention. .
Vom Prinzip her wäre auch eine Verschraubung oder eine Nietung denkbar.In principle, a screw or a riveting would be conceivable.
