Abstract
Eine Hochdruckpumpe (1), die insbesondere als Radial- oder Reihenkolbenpumpe für Brennstoffeinspritzanlagen von luftverdichtenden, selbstzündenden Brennkraftmaschinen dient, weist eine Pumpenbaugruppe (13) und eine Antriebswelle (6) auf, die einen der Pumpenbaugruppe (13) zugeordneten Nocken (9) umfasst. Dabei umfasst die Pumpenbaugruppe (13) eine Laufrolle (25), die mit ihrer Rollenoberfläche (35) an einer Lauffläche (10) des Nockens (9) abrollt. Eine Wälzbeanspruchbarkeit der Laufrolle (25) an der Rollenoberfläche (35) der Laufrolle (25) und eine Wälzbeanspruchbarkeit (9) an der Lauffläche (10) des Nockens (9) sind dabei gleich groß vorgegeben. Bei der hochdynamischen Beanspruchung des Nockens (9) und der Laufrolle (25) im Betrieb ergibt sich dadurch eine kritische Schwellspannung für beide Bauteile (9, 25), die für beide Bauteile (9, 25) gleich kritisch ist.A high-pressure pump (1), which serves in particular as a radial or inline piston pump for fuel injection systems of air-compressing, self-igniting internal combustion engines, has a pump assembly (13) and a drive shaft (6) which comprises a cam (9) associated with the pump assembly (13). In this case, the pump assembly (13) comprises a roller (25) which rolls with its roller surface (35) on a running surface (10) of the cam (9). A Wälzbeanspruchbarkeit the roller (25) on the roller surface (35) of the roller (25) and a Wälzbeanspruchbarkeit (9) on the running surface (10) of the cam (9) are given the same size. In the highly dynamic stress of the cam (9) and the roller (25) during operation, this results in a critical threshold voltage for both components (9, 25), which is equally critical for both components (9, 25).

Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Hochdruckpumpe mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass ein zuverlässiger Betrieb, insbesondere eine verbesserte Haltbarkeit des Nockens und/oder der Laufrolle, erzielt ist. Speziell sind der Nocken und die Laufrolle im Hinblick auf die im Betrieb auftretende schwellende Beanspruchung verbessert ausgestaltet.The High-pressure pump according to the invention with the features of claim 1 has the advantage that a reliable Operation, in particular improved durability of the cam and / or the roller is achieved. Specifically, the cam and the roller in view of the swelling stress occurring during operation improved designed.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der im Anspruch 1 angegebenen Hochdruckpumpe möglich.By the measures listed in the dependent claims are advantageous developments of specified in claim 1 High pressure pump possible.
Vorteilhaft ist es, dass ein Radius der Laufrolle kleiner ist als ein Krümmungsradius des Nockens an einer Stelle der Lauffläche, an der die Laufrolle in einem oberen Totpunkt der Pumpenbaugruppe anliegt, und dass ein Elastizitätsmodul eines Laufrollen-Werkstoffs, aus dem die Laufrolle zumindest an ihrer Rollenoberfläche gebildet ist, kleiner ist als ein Elastizitätsmodul eines Nocken-Werkstoffs, aus dem der Nocken zumindest an seiner Lauffläche gebildet ist. Hierdurch kann bei unterschiedlichen Geometrien der Laufrolle und des Nockens die Ausprägung einer kritischen Schwellspannung für die Laufrolle und den Nocken im Betrieb gleich kritisch ausgelegt werden. Hierdurch ist eine Optimierung hinsichtlich einer Streckgrenze der Laufrolle und einer Streckgrenze des Nockens möglich. Im oberen Totpunkt ist die Hertzsche Pressung an der Rollenoberfläche der Laufrolle gleich groß wie die Hertzsche Pressung an der Lauffläche des Nockens. Die Hertzsche Pressung muss dabei jeweils kleiner sein als die Streckgrenze der Laufrolle beziehungsweise des Nockens. In vorteilhafter Weise kann durch die angepasste Ausgestaltung der Laufrolle an den Nocken die Ermüdung der beiden Bauteile Laufrolle und Nocken optimiert werden.Advantageous it is that a radius of the roller is smaller than a radius of curvature of the cam at a point of the tread on which the Roller is in a top dead center of the pump assembly, and that a modulus of elasticity of a pulley material, from which the roller at least on its roller surface is smaller than a Young's modulus of one Cam material from which the cam at least on its tread is formed. This allows for different geometries of Caster and the cam the expression of a critical Threshold voltage for the roller and the cam during operation be interpreted equally critical. This is an optimization in terms of a yield strength of the roller and a yield strength of the Cam possible. At top dead center is the Hertzian pressure on the roller surface of the roller the same size as the Hertzian pressure on the tread of the cam. The Hertzian pressure must be smaller than the yield strength the roller or the cam. In an advantageous way can by the adapted design of the roller to the cam the fatigue of the two components roller and cam optimized become.
Vorteilhaft ist es, dass der Radius der Laufrolle kleiner ist als der Krümmungsradius des Nockens an der Stelle der Lauffläche, an der die Laufrolle in einem oberen Totpunkt der Pumpenbaugruppe anliegt und dass die Laufrolle zumindest eine Bohrung aufweist, die sich zumindest teilweise in Richtung einer Drehachse der Laufrolle erstreckt. Hierbei ist es ferner vorteilhaft, dass die Bohrung bezüglich der Drehachse der Laufrolle zumindest im wesentlichen als axiale oder zumindest im Wesentlichen als koaxiale Bohrung ausgestaltet ist und/oder dass die Bohrung als Durchgangsbohrung ausgestaltet ist, die sich von einer Seite der Laufrolle zu einer anderen Seite der Laufrolle erstreckt. Hierdurch kann bei unterschiedlichen Geometrien im oberen Totpunkt eine Verringerung der Steiflgkeit der Laufrolle im Bereich ihrer Rollenoberfläche erzielt werden.Advantageous it is that the radius of the roller is smaller than the radius of curvature of the cam at the location of the tread at which the caster abuts in a top dead center of the pump assembly and that the Roller has at least one bore, at least partially extends in the direction of a rotation axis of the roller. Here is it is further advantageous that the bore with respect to the axis of rotation the roller at least substantially as axial or at least is designed substantially as a coaxial bore and / or that the bore is designed as a through hole extending from one side of the roller extends to another side of the roller. This allows for different geometries at top dead center a reduction in the stiffness of the roller in the area of its Roll surface can be achieved.
Vorteilhaft ist es auch, dass der Radius der Laufrolle kleiner ist als der Krümmungsradius des Nockens an der Stelle der Lauffläche, an der die Laufrolle in einem oberen Totpunkt der Pumpenbaugruppe anliegt, und dass zumindest eine Druckeigenspannung der Laufrolle an ihrer Rollenoberfläche erhöht ist. Speziell ist es vorteilhaft, dass die Rollenoberfläche der Laufrolle einsatzgehärtet und/oder kugelgestrahlt und/oder rolliert und/oder nitriert und/oder nitrocarburiert ist. Hierdurch kann bei unterschiedlichen Geometrien der Laufrolle und des Nockens am oberen Totpunkt die Wälzfestigkeit der Laufrolle durch Einbringen von Druckeigenspannung an der Oberfläche erhöht werden. Hierdurch ist eine vorteilhafte Anpassung der Laufrolle an den Nocken möglich.Advantageous it is also that the radius of the roller is smaller than the radius of curvature of the cam at the location of the tread at which the caster abuts in a top dead center of the pump assembly, and that at least a compressive residual stress of the roller on its roller surface is increased. Specifically, it is advantageous that the roll surface case hardened and / or shot peened and / or rolled and / or nitrided and / or nitrocarburised. hereby can with different geometries of the roller and the cam at top dead center, the rolling resistance of the roller through Incorporation of compressive residual stress on the surface increased become. This is an advantageous adaptation of the roller possible at the cams.
Vorteilhaft ist es, dass der Radius der Laufrolle größer ist als der Krümmungsradius des Nockens an der Stelle der Lauffläche, an der die Laufrolle in einem oberen Totpunkt der Pumpenbaugruppe anliegt, und dass der Elastizitätsmodul des Laufrollen-Werkstoffs, aus dem die Laufrolle zumindest an ihrer Rollenoberfläche gebildet ist, größer ist als der Elastizitätsmodul des Nocken-Werkstoffs, aus dem der Nocken zumindest an seiner Lauffläche gebildet ist. Hierdurch kann eine vorteilhafte Anpassung der Laufrolle und des Nockens aneinander erfolgen. Hierbei ist es auch möglich, dass zumindest eine Druckeigenspannung des Nockens an seiner Lauffläche erhöht ist.It is advantageous that the radius of the roller is greater than the radius of curvature of the cam at the location of the tread on which the Laufrol le is in a top dead center of the pump assembly, and that the modulus of elasticity of the roller material, from which the roller is formed at least on its roller surface, is greater than the modulus of elasticity of the cam material from which the cam is formed at least on its tread. This allows an advantageous adaptation of the roller and the cam to each other. In this case, it is also possible that at least one compressive residual stress of the cam is increased at its tread.
Vorteilhaft ist es, dass ein Elastizitätsmodul und/oder eine Wälzfestigkeit und/oder eine Querdehnungszahl des Laufrollen-Werkstoffs, aus dem die Laufrolle zumindest an ihrer Rollenoberfläche gebildet ist, und ein Elastizitätsmodul und/oder eine Wälzfestigkeit und/oder eine Querdehnungszahl des Nocken-Werkstoffs, aus dem der Nocken zumindest an seiner Lauffläche gebildet ist, jeweils zumindest näherungsweise gleich groß vorgegeben sind und dass ein Radius der Laufrolle und ein Krümmungsradius des Nockens im Bereich einer Stelle der Lauffläche, an der die Lauffläche in einem oberen Totpunkt der Pumpenbaugruppe anliegt, zumindest näherungsweise gleich groß vorgegeben sind. Beispielsweise können die Laufrolle und der Nocken aus gleichen oder vergleichbaren Stählen gebildet sein, die hinsichtlich der Elastizitätsmodule, der Wälzfestigkeit und der Querdehnungszahl gleich oder vergleichbar ausgestaltet sind. In diesem Fall ist der Krümmungsradius des Nockens im Bereich des oberen Totpunkts zumindest näherungsweise gleich dem Radius der Laufrolle ausgelegt, so dass sich eine vorteilhafte Anpassung ergibt. Hierbei ist es ferner vorteilhaft, dass der Radius der Laufrolle und der Krümmungsradius des Nockens an der Stelle der Lauffläche, an der die Laufrolle in dem oberen Totpunkt der Pumpenbaugruppe anliegt, um weniger als 5% voneinander abweichen.Advantageous it is that a modulus of elasticity and / or a rolling resistance and / or a transverse strain number of the roller material, from the the roller formed at least on its roller surface is, and a modulus of elasticity and / or a rolling resistance and / or a transverse strain number of the cam material from which the Cam is formed at least on its tread, respectively at least approximately the same size are and that a radius of the roller and a radius of curvature of the Cam in the area of a point of the tread at the the tread at a top dead center of the pump assembly is present, at least approximately the same size specified are. For example, the roller and the cam be made of the same or comparable steels, in terms of moduli of elasticity, rolling resistance and the transverse strain number are the same or comparable designed. In this case, the radius of curvature of the cam is in the range of top dead center at least approximately equal to Radius of the roller designed so that a favorable adjustment results. It is also advantageous that the radius of the roller and the radius of curvature of the cam at the location of the tread, at the the roller in the top dead center of the pump assembly is less than 5% different from each other.
