Definitions
- the invention relates to a blade bearing ring of a turbocharger with turbine blades adjustable in the blade bearing ring according to the preamble of patent claim 1.
- a suitably suitable material must have a sufficient creep resistance, high dimensional stability, by which a thermal distortion is avoided even at high temperatures on the blade bearing ring, a high wear resistance and a sufficient oxidation resistance. If it comes to delay, creep or a strong oxidation of a generic blade bearing ring, this can lead to the blocking of the turbine vanes, that is, the turbocharger cross-section can no longer be adapted to the driving condition of the engine by a vane adjustment.
- EP 1396620 discloses a turbocharger exhaust system including a vane bearing ring having improved heat resistance thanks to an alloy wherein the nonmetallic alloy components are not more than 0.1% by weight.
- the invention is concerned with the problem of designing generic blade bearing rings materially reliable for use at extremely high temperatures.
- a high creep resistance and high strength at temperatures above 850 ° C is desired.
- the mobility of the turbine blades in the generic blade bearing ring should be absolutely guaranteed.
- the invention is based on the general idea that in higher performance engines, in particular the creep resistance and strength of a blade bearing ring material, increased requirements are met by an austenitic iron material having a sulfur content causing a solid lubricant property to which high melting alloying elements are added, these alloying elements being present singly or in the presence several of these elements should occupy a proportion by weight of at least one percent by weight up to six percent by weight.
- This diagram shows the coefficient of thermal expansion of alloys A and B as a function of temperature.
- the ordinate represents the hot hardness (in HV10) as a function of the temperature for alloys A and B.
- the ordinate shows the hardness (in HB 2.5 / 187.5) of the alloys A and B after 2 hours aging and air cooling as a function of the temperature.

Description
Die Erfindung betrifft einen Schaufellagerring eines Turboladers mit in dem Schaufellagerring verstellbaren Turbinenschaufeln nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a blade bearing ring of a turbocharger with turbine blades adjustable in the blade bearing ring according to the preamble of
Bei modernen Hochleistungsmotoren werden an einen dauerhaft funktionsfähigen Schaufellagerring, wie er beispielsweise als Bauteil 38 bei einem Turbolader nach
Als Schaufellagerringe werden bisher hauptsächlich ferritische Werkstoffe, die einen hohen Anteil an Chrom und Chromkarbiden enthalten, eingesetzt. Bei thermisch höher belasteten Schaufellagerringen werden austenitische Materialien, die Chromkarbide enthalten, verwendet. Eine derartige Legierung enthält beispielsweise folgende Anteile in jeweils Gewichtsprozent angegeben: C = 0,4 - 0,7, Cr = 18 - 21, Ni = 12 - 14, S = 0,2 - 0,4, Si = 1,8 - 2,2 mit Rest Eisen und unspezifizierten Legierungsbestandteilen bzw. Verunreinigungen bis zu 3 %. Eine solche Legierung wird nachfolgend als Legierung PL 23 bezeichnet.As scoop bearing rings so far mainly ferritic materials containing a high proportion of chromium and chromium carbides are used. For thermally loaded blade bearing rings, austenitic materials containing chromium carbides are used. Such an alloy contains, for example, the following proportions in each case percent by weight: C = 0.4-0.7, Cr = 18-21, Ni = 12-14, S = 0.2-0.4, Si = 1.8 2.2 with residual iron and unspecified alloying components or impurities up to 3%. Such an alloy is referred to below as alloy PL 23.
Die Erfindung beschäftigt sich mit dem Problem, gattungsgemäße Schaufellagerringe werkstoffmäßig für einen Einsatz bei extrem hohen Temperaturen funktionssicher auszulegen. Insbesondere wird ein hoher Kriechwiderstand und eine hohe Festigkeit bei Temperaturen von oberhalb 850° C angestrebt. Insbesondere bei derart hohen Temperaturen soll die Beweglichkeit der Turbinenschaufeln in dem gattungsgemäßen Schaufellagerring absolut sichergestellt sein.The invention is concerned with the problem of designing generic blade bearing rings materially reliable for use at extremely high temperatures. In particular, a high creep resistance and high strength at temperatures above 850 ° C is desired. In particular, at such high temperatures, the mobility of the turbine blades in the generic blade bearing ring should be absolutely guaranteed.
Gelöst wird diese Aufgabe durch einen gattungsgemäßen Schaufellagerring mit einer Legierungszusammensetzung nach dem kennzeichnenden Merkmal des Anspruchs 1.This object is achieved by a generic blade bearing ring with an alloy composition according to the characterizing feature of
Besonders vorteilhafte Schaufellagerlegierungen sind Gegenstand der Unteransprüche, wobei sich die Legierungen nach den Ansprüchen 3 und 4 als eine besonders gute Lösung herausgestellt haben.Particularly advantageous blade bearing alloys are the subject of the dependent claims, wherein the alloys according to the Claims 3 and 4 have been found to be a particularly good solution.
Die Erfindung beruht auf dem allgemeinen Gedanken, die bei leistungsgesteigerten Motoren an insbesondere die Kriechbeständigung und Festigkeit eines Schaufellagerringmaterials gestiegenen Anforderungen durch einen austenitischen Eisenwerkstoff mit einem eine feste Schmierstoffeigenschaft bewirkenden Schwefelanteil zu erfüllen, dem hochschmelzende Legierungselemente zugesetzt sind, wobei diese Legierungselemente einzeln oder bei einem Vorhandensein mehrerer dieser Elemente einen Gewichtsanteil zwischen mindestens einem Gewichtsprozent bis zu sechs Gewichtsprozenten einnehmen sollen.The invention is based on the general idea that in higher performance engines, in particular the creep resistance and strength of a blade bearing ring material, increased requirements are met by an austenitic iron material having a sulfur content causing a solid lubricant property to which high melting alloying elements are added, these alloying elements being present singly or in the presence several of these elements should occupy a proportion by weight of at least one percent by weight up to six percent by weight.
Eine erfindungsgemäß erreichbare, erhöhte Kriechbeständigkeit des Schaufellagerringwerkstoffes bedingt bei höheren Temperaturen eine hohe Maßstabilität der Schaufellagerringe. Durch die Festschmierstoffwirkung, die von dem Schwefelanteil innerhalb der Legierung ausgeht, besteht eine gute Schmierung an insbesondere der Kontaktfläche zwischen dem Schaufellagerring und einer in diesem gelagerten Turbinenschaufel. Bei einem erfindungsgemäßen Materialeinsatz wird ein Blockieren der Turbinenschaufeln, das heißt der Leitschaufeln, bei hohen Temperaturen sicher vermieden.An inventively achievable, increased creep resistance of the blade bearing ring material requires high dimensional stability of the blade bearing rings at higher temperatures. Due to the solid lubricant effect, which starts from the sulfur content within the alloy, there is a good lubrication, in particular the contact surface between the blade bearing ring and a turbine blade mounted in this. In the case of a material insert according to the invention, blocking of the turbine blades, that is to say of the guide vanes, is reliably avoided at high temperatures.
In der Zeichnung sind einige Eigenschaftsdiagramme für erfindungsgemäße Schaufellagerringmaterialien angegeben. Die in den einzelnen Diagrammen angegebenen Kurven betreffen soweit sie mit A bezeichnet sind, einen Werkstoff nach Anspruch 3 und soweit sie mit B bezeichnet sind, einen Werkstoff nach Anspruch 4.In the drawing, some property diagrams are given for blade bearing ring materials according to the invention. The curves given in the individual diagrams relate to that extent they are designated A, a material according to claim 3 and as far as they are designated B, a material according to claim 4.

Dieses Diagramm zeigt den thermischen Ausdehnungskoeffizienten der Legierungen A und B in Abhängigkeit der Temperatur.This diagram shows the coefficient of thermal expansion of alloys A and B as a function of temperature.
Bei diesem Diagramm ist in der Ordinate die Warmhärte (in HV10) in Abhängigkeit der Temperatur bei den Legierungen A und B aufgetragen.In this diagram, the ordinate represents the hot hardness (in HV10) as a function of the temperature for alloys A and B.
Auf der Ordinate ist die Härte (in HB 2,5/187,5) der Legierungen A und B nach einer Auslagerung von jeweils 2 Stunden und einer Luftabkühlung in Abhängigkeit der Temperatur gezeigt.The ordinate shows the hardness (in HB 2.5 / 187.5) of the alloys A and B after 2 hours aging and air cooling as a function of the temperature.
Diese Fig. enthält eine Tabelle in der für die Legierungen A und B jeweils bei Raumtemperatur angegeben sind Werte für p = Dichte, λ = Wärmeleitfähigkeit, Rp02 = Dehngrenze, Rm = Zugfestigkeit, E = Elastizitätsmodul.This figure contains a table in which for the alloys A and B respectively at room temperature are given values for p = density, λ = thermal conductivity, R p02 = yield strength, R m = tensile strength, E = elastic modulus.
