Abstract
Description
Die Erfindung betrifft eine Lageranordnung mit mindestens einem Kegelrollenlager, mit dem ein Wellenteil relativ zu einem Gehäuse gelagert wird, wobei das Gehäuse mindestens eine konisch ausgebildete Fläche aufweist, auf der ein einen Ring des Kegelrollenlagers bildendes Laufbahnteil angeordnet ist.The The invention relates to a bearing arrangement with at least one tapered roller bearing, with which a shaft part is mounted relative to a housing, wherein the casing Has at least one conical surface on which a one Ring of the tapered roller bearing forming raceway part is arranged.
Eine
Lageranordnung dieser Art ist aus der
Der Vorteil dieser Ausgestaltung ist, dass ein gewichtsarmes, jedoch stabiles Lager für die Welle geschaffen wird. Das Gehäuse besteht zumeist aus einem Material, das nicht für die Aufnahme der hohen Kräfte bzw. Flächenpressungen geeignet ist, die über das Lager zu übertragen sind. Der eingesetzte Laufbahnring – zumeist aus gehärtetem Stahl – besitzt die benötigte Festigkeit. Da er jedoch als dünnwandiges Blechteil ausgebildet ist, ist sein Gewicht nicht hoch.Of the Advantage of this embodiment is that a low-weight, however stable bearing for the wave is created. The housing is usually made of a material, not for that the admission of the high forces or surface pressure that is suitable over the Warehouse to transfer are. The used raceway ring - mostly made of hardened steel - has the needed Strength. Since he is a thin-walled sheet metal part is formed, its weight is not high.
Die genannte Lösung erkennt das Problem, dass die feste Anordnung der Laufbahnringe in den konischen Gehäuseabschnitten sichergestellt sein muss. Daher schlägt die vorbekannte Lösung vor, die Laufbahnbleche in die entsprechende Innenfläche im Gehäuse einzupressen oder durch Kaltwalzen einzurollen.The called solution recognizes the problem that the fixed arrangement of raceway rings in the conical housing sections must be ensured. Therefore, the previously known solution proposes to press the raceway plates into the corresponding inner surface in the housing or through Roll in cold rolls.
Es hat sich herausgestellt, dass diese Anbringung problematisch ist. Im Laufe der Zeit kann es infolge der Lagerkräfte zu einem Lösen der Laufbahnringe von ihren konischen Sitzen im Gehäuse kommen, so dass der Laufbahnring relativ zum Gehäuse sowohl axial als auch in Umfangsrichtung wandern kann. Dies hat infolge auftretenden Passungsrosts negative Effekte, so dass im Ergebnis das Lager ausfallen kann.It it has been found that this attachment is problematic. Over time, it may be due to the bearing forces to release the Raceway rings come from their conical seats in the case, leaving the raceway ring relative to the housing can migrate both axially and in the circumferential direction. this has as a result of fretting corrosion negative effects, so that in Result the bearing can fail.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Lageranordnung der eingangs genannten Art zu schaffen, die ein diesbezüglich verbessertes Verhalten aufweist. Es soll insbesondere sichergestellt sein, dass auch bei langem Gebrauch der Laufbahnring relativ zum Gehäuse stets so festgelegt ist, dass es zu keinem Wandern des Rings relativ zum Gehäuse kommen kann. Die Stabilität der Lageranordnung soll damit erhöht und die Gebrauchsdauer verlängert werden. Schließlich sollen die Herstellkosten gering sein, so dass sich das Lager auch und insbesondere für die Großserienfertigung eignet.Of the Invention is therefore the object of a bearing assembly to create the type mentioned, the improved in this regard Behavior. In particular, it should be ensured that even with long use of the raceway ring relative to the housing always is set so that there is no wandering of the ring relative to casing can come. The stability the bearing assembly is thus increased and the service life can be extended. After all the manufacturing costs should be low, so that the camp also and in particular for the mass production suitable.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass das Laufbahnteil des Kegelrollenlagers auf der konisch ausgebildeten Fläche durch Stoffschluss festgelegt ist.The solution this object by the invention is characterized in that the raceway portion of the tapered roller bearing on the conical area is determined by material connection.
Diese stoffschlüssige Verbindung zwischen konisch ausgebildeter Fläche und Laufbahnteil kann punktuell oder flächig ausgeführt sein. In letzterem Falle ist bevorzugt vorgesehen, dass die flächige Verbindung zwischen konisch ausgebildeter Fläche und Laufbahnteil im wesentlichen die gesamte konische ausgebildete Fläche umfasst.These cohesive Connection between conical surface and raceway part can be punctual or flat accomplished be. In the latter case, it is preferably provided that the flat connection between conical surface and career part substantially includes the entire conical surface formed.
Das Laufbahnteil besteht vorzugsweise aus einem Blech mit weitgehend konstanter Dicke, wie es an sich im Stand der Technik bekannt ist.The Runway part is preferably made of a sheet with largely constant thickness, as is known per se in the prior art.
Der Stoffschluss zwischen konisch ausgebildeter Fläche und Laufbahnteil wird bevorzugt durch ein Lot gebildet, wobei bevorzugt ein Hartlot vorgesehen wird.Of the Material bond between conical surface and career part is preferred formed by a solder, wherein preferably a braze is provided.
Alternativ dazu kann aber als Stoffschluss auch eine Verschweißung vorgesehen werden. Hierfür hat sich insbesondere eine Laserverschweißung oder eine Elektronenstrahlverschweißung bewährt.alternative But this can also be provided as a material bond and a weld become. Therefor In particular, a laser welding or electron beam welding has proven itself.
Als weitere Alternative für den Stoffschluss kann ein Klebstoff vorgesehen werden, der bevorzugt entsprechend temperaturstabil ausgewählt wird, um den Betriebtemperaturen der Lageranordnung problemlos widerstehen zu können.When another alternative for the adhesive can be provided an adhesive, preferably according to temperature stable selected will easily withstand the operating temperatures of the bearing assembly to be able to.
Das Laufbahnteil besteht vorzugsweise aus Stahlblech, insbesondere aus rostfreiem Edelstahlblech. Es kann durch einen Tiefziehvorgang, durch einen Kaltwalzvorgang, durch einen Drückwalzvorgang, durch einen Rolliervorgang und/oder durch einen Fließpressvorgang hergestellt sein.The Runway part is preferably made of sheet steel, in particular stainless steel sheet. It can by a deep drawing process, by a cold rolling process, by a flow-forming process, by a Rolling and / or produced by an extrusion process.
Die vorgeschlagene Lageranordnung wird zumeist mit zwei Kegelrollenlagern realisiert, die in axialer Richtung nebeneinander angeordnet sind. Die beiden Lager können in O-Anordnung positioniert sein.The proposed bearing arrangement is usually with two tapered roller bearings realized, which are arranged side by side in the axial direction. The both camps can be positioned in O arrangement.
Bevorzugt sind die Laufbahnteile einer Wärmebehandlung, insbesondere einem Härtevorgang, möglicherweise unter Schutzgas unterzogen. Eine hohe Gebrauchsdauer des Lagers ergibt sich, wenn die als Lagerringe fungierenden Laufbahnteile eine Oberflächenhärte von mindestens 50 HRC aufweisen.Prefers are the raceway parts of a heat treatment, especially a hardening process, possibly under protective gas. A long service life of the warehouse results when the raceway parts acting as bearing rings a surface hardness of at least 50 HRC.
Mit dem Erfindungsvorschlag wird eine einfach aufgebaute und kostengünstige Lageranordnung mittels Kegelrollenlager geschaffen, die sich insbesondere für die Großserienfertigung eignet. Die Lageranordnung ist relativ leicht und weist eine hohe Stabilität auf. Das Laufbahnteil ist an der konisch ausgebildeten Fläche des Gehäuses dauerhaft und fest angeordnet, so dass eine Relativbewegung des Laufbahnteils relativ zum Gehäuse ausgeschlossen ist.With the proposed invention, a simple and inexpensive bearing arrangement is created by means of tapered roller bearings, which is particularly suitable for mass production. The bearing assembly is relatively lightweight and has a high stability. The raceway part is at the conical trained surface of the housing permanently and firmly arranged so that a relative movement of the raceway part is excluded relative to the housing.
Damit ist der kritische Punkt der Anbindung eines Laufbahnteils im Gehäuse überwunden. Sowohl ein Verdrehen als auch ein axiales Verschieben des Laufbahnteils relativ zum Gehäuse ist zuverlässig verhindert. Dies gilt insbesondere für den regelmäßigen Anwendungsfall, dass das Gehäuse und das Laufbahnteil aus unterschiedlichem Material bestehen (häufig: Guss und Stahlblech).In order to the critical point of connecting a raceway part in the housing has been overcome. Both a twisting and an axial displacement of the raceway part relative to the housing is reliable prevented. This applies in particular to the regular application, that the case and the track part consist of different material (often: cast and steel sheet).
Besonders vorteilhaft ist es, dass aufwändige Lösungen vermieden werden können, bei denen eine Verhinderung der Relativbewegung durch Formschluss versucht wird zu erreichen, was jedoch einen entsprechend hohen Fertigungsaufwand erfordert, der kostenintensiv ist.Especially it is advantageous that elaborate solutions can be avoided in which a prevention of the relative movement by positive engagement is trying to achieve, but what a correspondingly high Manufacturing costs required, which is costly.
Der bevorzugte Anwendungsfall für die vorgeschlagene Lageranordnung findet sich bei Radlagerungen und Getriebelagerungen im Kfz-Bau, insbesondere im LKW-Bereich. Der Erfindungsvorschlag eignet sich weiter auch besonders gut für andere Anwendungen, bei denen Lageraußenringe in Naben bzw. Gehäuse eingepresst werden.Of the preferred application for The proposed bearing arrangement is found in wheel bearings and transmission bearings in the automotive industry, especially in the truck sector. The proposed invention is also particularly suitable for others Applications where bearing outer rings in hubs or housing be pressed.

Bei der stoffschlüssigen Verbindung handelt es sich im Ausführungsbeispiel um eine solche, die ein Hartlot einsetzt.at the cohesive Connection is in the exemplary embodiment one such who uses a braze.
Das Hartlot ist in der Regel eine eutektische Legierung (meist auf der Basis von Silber oder Messing). Es eignet sich im Gegensatz zum Weichlot (das meist aus einer Zinn-Blei-Basis besteht) auch für mechanisch stärker beanspruchte metallische Verbindungen, wie es für den vorliegenden Anwendungsfall typisch ist. Eine Hartlotverbindung weist zum Teil eine höhere Festigkeit als der Grundwerkstoff auf. Die Verarbeitungstemperaturen für Hartlote liegen zwischen 500 °C und 1.000°C. Als Wärmequellen können z. B. Gasbrenner oder Laser eingesetzt werden.The Brazing is usually a eutectic alloy (mostly on the Base of silver or brass). It is in contrast to Soft solder (which usually consists of a tin-lead base) also for mechanical stronger claimed metallic compounds, as is the case for the present application typical. A braze joint sometimes has a higher strength as the base material. The processing temperatures for brazing alloys are between 500 ° C and 1,000 ° C. As heat sources can z. As gas burners or lasers are used.
