Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Lagerrings eines Wälzlagers, wobei ein Ringkörper an einer radial außenliegenden oder innenliegenden Umfangsfläche mit mindestens einer Laufbahn für Wälzkörper versehen wird und wobei der Ringkörper an einer radial innenliegenden oder außenliegenden Umfangsfläche mit einer zylindrischen Sitzfläche versehen wird, wobei die zylindrische Sitzfläche einer spanenden Hartbearbeitung unterzogen wird.The invention relates to a method for producing a bearing ring of a rolling bearing, wherein an annular body is provided on a radially outer or inner circumferential surface with at least one raceway for rolling elements and wherein the annular body is provided on a radially inner or outer peripheral surface with a cylindrical seat, wherein the cylindrical seat is subjected to a machining hard machining.
Lagerringe dieser Art werden auf oder in einem Bauteil angeordnet. Beispielsweise kann ein Lagerinnenring mittels eines Presssitzes auf einer Welle angeordnet werden, um ihn dauerhaft während seiner Gebrauchsdauer auf diesem Bauteil zu fixieren.Bearing rings of this type are arranged on or in a component. For example, a bearing inner ring can be arranged by means of a press fit on a shaft in order to fix it permanently during its service life on this component.
Bei entsprechender Belastung während des Einsatzes eines Wälzlagers treten mitunter Probleme mit Rissbildung im Laufbahnbereich auf. In diesem Zusammenhang ist es bekannt, dass sich bei hohen Lasten und in Verbindung mit auftretendem Schlupf auf der Laufbahn Risse bilden, die auf der Laufbahnoberfläche in axiale Richtung verlaufen. Daher kommt es sehr häufig zu Reibkorrosion an der Lagerbohrung und an der gelagerten Welle. Zusätzlich ist eine Umlaufbiegung relevant, die bei der Rotation des Lagerrings wirkt.With appropriate load during the use of a rolling bearing, there are sometimes problems with crack formation in the raceway area. In this connection, it is known that cracks are formed on the raceway at high loads and in conjunction with slip occurring on the raceway surface in the axial direction. Therefore, it often comes to fretting corrosion on the bearing bore and the mounted shaft. In addition, a circulation bend is relevant, which acts during the rotation of the bearing ring.
Die genannten Effekte begrenzen die Gebrauchsdauer des Wälzlagers und führen mitunter zu frühzeitigen Ausfällen der Lagerung. The effects mentioned limit the service life of the rolling bearing and sometimes lead to premature failure of storage.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren zur Herstellung eines Lagerrings zu schaffen, mit dem die Neigung zur Rissbildung jedenfalls stark reduziert ist. Auch soll das Auftreten von Reibkorrosion im Bereich der zylindrischen Sitzfläche des Lagers durch Wellenbiegung unter Last vermindert werden. The invention has for its object to provide a generic method for producing a bearing ring, with which the tendency for cracking is at least greatly reduced. Also, the occurrence of fretting corrosion in the region of the cylindrical seat of the bearing is to be reduced by shaft deflection under load.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass der letzte Bearbeitungsschritt der zylindrischen Sitzfläche durch eine Honoperation gebildet wird, wobei der Lagerring vorgesehen wird, um mit seiner zylindrischen Sitzfläche, vorzugsweise mit Presssitz, auf einem oder in einem Bauteil angeordnet zu werden, wobei das Honen der zylindrischen Sitzfläche derart durchgeführt wird, dass der radiale Differenzbetrag zwischen maximalem und minimalem Wert über dem Umfang der zylindrischen Sitzfläche höchstens gleich dem folgenden Wert ist: mit:
- hc:
- radialer Differenzbetrag zwischen maximalem und minimalem Wert des Radius über dem Umfang der zylindrischen Sitzfläche in mm;
- D:
- Durchmesser der zylindrischen Sitzfläche des Lagerrings in mm;
- E:
- Elastizitätsmodul des Materials des Lagerrings in N/mm2;
- σc:
- kritische Umfangsspannung im Lagerring vor dem Aufbringen einer äußeren Belastung, gegebenenfalls nach der Herstellung eines Presssitzes, in N/mm2 (MPa);
- σnom:
- nominale Umfangsspannung im Lagerring nach seiner Montage, gegebenenfalls hervorgerufen durch einen Presssitz, in N/mm2 (MPa).
- h c:
- radial difference between the maximum and minimum values of the radius over the circumference of the cylindrical seat in mm;
- D:
- Diameter of the cylindrical seat of the bearing ring in mm;
- e:
- Modulus of elasticity of the material of the bearing ring in N / mm 2;
- σ c:
- critical hoop stress in the bearing ring before application of an external load, possibly after the production of an interference fit, in N / mm 2 (MPa);
- σ nom :
- nominal hoop stress in the bearing ring after its installation, possibly caused by an interference fit, in N / mm 2 (MPa).
Als kritische Umfangsspannung (σc) im Lagerring vor dem Aufbringen einer äußeren Belastung wird bevorzugt ein Wert zwischen 180 MPa und 220 MPa zugrunde gelegt, vorzugsweise von 200 MPa.The critical hoop stress (σ c ) in the bearing ring before the application of an external load is preferably based on a value between 180 MPa and 220 MPa, preferably of 200 MPa.
Vorzugsweise wird vor der Honoperation ein Hartdrehvorgang durchgeführt, um die zylindrische Sitzfläche zu erzeugen.Preferably, a hard turning operation is performed before the honing operation to produce the cylindrical seating surface.
Es kann auch vorgesehen sein, dass vor der Honoperation ein Schleifvorgang durchgeführt wird, um die zylindrische Sitzfläche zu erzeugen.It may also be provided that a grinding operation is performed before the honing operation in order to produce the cylindrical seating surface.
Es hat es sich überraschend herausgestellt, dass ein besonders gutes Ergebnis erzielt wird, wenn besagte Honoperation – insbesondere bei späterem Einbau des Lagerrings mittels Presssitz – in einem solchen Maße durchgeführt wird, bis der genannte maximale radiale Differenzbetrag zwischen maximalem und minimalem Wert über dem Umfang der zylindrischen Sitzfläche vorliegt. It has surprisingly been found that a particularly good result is achieved when said honing operation - in particular with subsequent installation of the bearing ring by means of press fit - carried out to such an extent until said maximum radial difference between maximum and minimum value over the scope of cylindrical seat is present.
Die Laufbahn des Lagerrings ist bevorzugt hartgedreht; sie kann auch hartgewalzt werden.The raceway of the bearing ring is preferably hard-turned; it can also be hard-rolled.
Die Laufbahn und/oder die zylindrische Sitzfläche sind bevorzugt brüniert. The track and / or the cylindrical seat are preferably burnished.
Das vorgeschlagene Verfahren hat sich besonders bei Lagerinnenringen bewährt. Genauso können aber auch Lageraußenringe hergestellt werden. Besonders bevorzugt werden Lagerringe von Kegelrollenlagern und von Zylinderrollenlagern erfindungsgemäß hergestellt. The proposed method has proven particularly in bearing inner rings. However, bearing outer rings can also be produced in the same way. Particularly preferred bearing rings of tapered roller bearings and cylindrical roller bearings are produced according to the invention.
Es hat sich gezeigt, dass die Neigung zur Rissbildung auf der Laufbahn des Lagerrings in erheblichem Maße reduziert werden kann, wenn das vorgeschlagene Verfahren eingesetzt wird. Ebenfalls kann Reibkorrosion vermindert werden. It has been found that the tendency to crack on the raceway of the bearing ring can be significantly reduced when the proposed method is used. Also, fretting corrosion can be reduced.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: In the drawing, an embodiment of the invention is shown. Show it:
In
Ist der Lagerring
Sofern kein Presssitz, sondern ein Lossitz vorliegt, ist die nominale Umfangsspannung σnom meist Null. Sie kann aber auch größer als Null sein, wenn beispielsweise im Falle eines Kegelrollenlager-Außenrings infolge einer Axiallast und einer hierdurch hervorgerufenen Aufweitung des Rings eine Umfangsspannung im Ring hervorgerufen wird. If there is no press fit but a loss seat, the nominal hoop stress σ nom is usually zero. But it can also be greater than zero, if, for example, in the case of a tapered roller bearing outer ring as a result of axial load and thereby caused by widening of the ring, a hoop stress in the ring is caused.
Weiterhin ist eine kritische Umfangsspannung σc (in MPa) definierbar, die im Lagerring nach der Herstellung, aber vor dem Aufbringen einer äußeren Belastung herrschen darf. Dieser Wert ist materialabhängig und kann bei Stahl beispielsweise 200 MPa betragen.Furthermore, a critical hoop stress σ c (in MPa) can be defined, which may prevail in the bearing ring after the production, but before the application of an external load. This value is material-dependent and may be 200 MPa for steel, for example.
In
Die zylindrische Bohrung
Die Laufbahn kann klassisch hergestellt werden, d. h. dass die Endkontur mittels Schleifen hergestellt wird. Es ist aber bevorzugt auch hier ein Hartdrehen und/oder ein Hartwalzen möglich, an das sich ggf. ein Honen anschließt. The track can be made classically, d. H. that the final contour is made by grinding. However, hard twisting and / or hard rolling is also possible here, possibly followed by honing.
Ein sehr vorteilhaftes Ergebnis und eine wesentliche Verbesserung gegen Risse in der Laufbahn werden erreicht, wenn der radiale Differenzbetrag hc folgenden Wert nicht überschreitet: A very advantageous result and a substantial improvement against cracks in the raceway are achieved if the radial difference h c does not exceed the following value:
Wie der Verlauf von hc aussieht, ist für verschiedene Werte der nominale Umfangsspannung σnom über dem Durchmesser D und für Stahl als Ringmaterial (E = 210.000 N/mm2) in
Man erkennt, dass – je näher sich der nominale Spannungswert dem kritischen Spannungswert nähert – in Abhängigkeit des Durchmessers D ein immer geringeres Maß für hc angestrebt werden muss, um eine dauerhafte Vermeidung von Rissen auf der Laufbahn
Demgemäß wird bei der Umsetzung der erfindungsgemäßen Idee so vorgegangen, dass anhand der vorgesehenen Konstruktion und dem geplanten Einsatz des Wälzlagers zunächst bestimmt wird, mit welcher Umfangsspannung σnom beispielsweise der Lagerinnenring auf seiner Welle sitzen wird. Dies ergibt sich insbesondere aus der vorgesehenen Passung zwischen dem zylindrischen Sitz des Lagerrings und der Welle. Hierfür können entsprechende Rechenprogramme eingesetzt werden, mit denen sich die nominale Umfangsspannung im Lagerring ermitteln lässt, der sich aufgrund des vorgesehenen Presssitzes ergibt. Accordingly, in the implementation of the idea according to the invention, the procedure is such that, based on the intended design and the planned use of the rolling bearing, it is first determined with which hoop stress σ nom, for example, the bearing inner ring will sit on its shaft. This results in particular from the intended fit between the cylindrical seat of the bearing ring and the shaft. For this purpose, appropriate computer programs can be used with which the nominal hoop stress in the bearing ring can be determined, which results from the intended interference fit.
Dann wird die kritische Umfangsspannung σc im Lagerring bestimmt, wie sie nach der Herstellung des Presssitzes und vor dem Aufbringen einer äußeren Belastung im Lagerring vorliegt. Dieser Wert ist werkstoffabhängig; ein Beispiel für besagte Spannung wurde oben genannt. Then, the critical hoop stress σ c is determined in the bearing ring, as it exists after the production of the press fit and before the application of an external load in the bearing ring. This value is material-dependent; an example of said voltage has been given above.
Anschließend kann anhand der oben aufgeführten mathematischen Beziehung bestimmt werden, wie groß der radiale Differenzbetrag hc werden darf. Subsequently, it can be determined from the above-mentioned mathematical relationship how large the radial difference h c may be.
Nach dem Schleifen der zylindrischen Bohrung erfolgt schließlich der Honprozess. Das Honen wird dabei so durchgeführt, dass der ermittelte maximale radiale Differenzbetrag eingehalten wird, was gegebenenfalls durch interaktives Messen geprüft wird. After grinding the cylindrical bore finally the honing process. The honing is carried out in such a way that the determined maximum radial difference amount is maintained, which is optionally checked by interactive measurement.
