Description
Die Erfindung betrifft ein Kegelrollenlager mit einem Innenring und einem Außenring, zwischen denen Kegelrollen angeordnet sind.The The invention relates to a tapered roller bearing with an inner ring and an outer ring, between which tapered rollers are arranged.
Kegelrollenlager dieser Art sind im Stand der Technik hinlänglich bekannt und werden für eine Vielzahl von Lageranwendungen eingesetzt. Der Kegelrollenlagerinnenring bzw. -außenring ist dabei zumeist als Massivteil ausgebildet, d. h. der Ring besteht aus einem Stahlteil, das am radial außenliegenden oder innenliegenden Umfang zylindrisch ausgebildet und zur Aufnahme in einer zylindrischen Gehäusebohrung oder auf einem zylindrischen Wellenabschnitt vorgesehen ist, während der andere innenliegende bzw. außenliegende Umfang kegelförmig ausgebildet ist und die Laufbahn für die Kegelrollen bildet.Tapered roller bearings of this type are well known in the art and are used for a variety used by warehouse applications. The tapered roller bearing inner ring or -außenring is usually designed as a solid part, d. H. the ring exists made of a steel part, on the radially outer or inner Cylindrical circumference formed and for receiving in a cylindrical housing bore or on a cylindrical shaft portion is provided during the other internal or external Scope cone-shaped is and the career for forms the tapered rollers.
Bei relativ geringer Lagerbelastung ist damit das Kegelrollenlager häufig überdimensioniert. Dies hat nicht nur Nachteile in Bezug auf das Gewicht des Lagers; auch die Herstellkosten sind entsprechend hoch.at Relatively low bearing load is thus the tapered roller bearing often oversized. This not only has disadvantages in terms of the weight of the bearing; The manufacturing costs are correspondingly high.
Dasselbe gilt mit Blick auf die Präzision der Lagerung. Massiv ausgebildete und präzise gefertigte Kegelrollenlagerringe können eine Welle relativ zu einem Gehäuse zwar sehr präzise lagern. Allerdings geht dies mit entsprechenden Herstellkosten einher, die in vielen Fällen nicht gerechtfertigt sind.The same thing applies with a view to precision storage. Massively formed and precisely manufactured tapered roller bearing rings can a shaft relative to a housing Although very precise to store. However, this is associated with corresponding manufacturing costs, the in many cases are not justified.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Kegelrollenlager der eingangs genannten Art zu schaffen, die sich insbesondere bei relativ moderaten oder geringen Anforderungen an die aufzunehmende Belastung und/oder Präzision der Lagerung dadurch auszeichnet, dass das Lager sehr leicht ist. Weiterhin sollen die Herstellkosten gering sein, so dass sich das Lager auch und insbesondere für die Großserienfertigung eignet.Of the Invention is therefore based on the object, a tapered roller bearing to create the type mentioned, in particular at relatively moderate or low demands on the male Load and / or precision Storage is characterized by the fact that the warehouse is very light. Furthermore, the production costs should be low, so that the Stock also and in particular for the mass production suitable.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass der Innenring und/oder der Außenring des Kegelrollenlagers durch ein Blechteil gebildet wird, das so ausgeformt ist, dass es einen Hohlraum aufweist.The solution this object by the invention is characterized in that the inner ring and / or the outer ring of the tapered roller bearing is formed by a sheet metal part, the like is formed so that it has a cavity.
Bevorzugt wird sowohl der Innenring als auch der Außenring des Kegelrollenlagers jeweils durch ein Blechteil gebildet, das so ausgeformt ist, dass es einen Hohlraum aufweist.Prefers Both the inner ring and the outer ring of the tapered roller bearing each formed by a sheet metal part, which is shaped so that it has a cavity.
Das vorgeschlagene Kegelrollenlager zeichnet sich damit durch ein geringes Gewicht bei geringem Materialeinsatz aus, so dass es leicht und preiswert herstellbar ist.The proposed tapered roller bearing is characterized by a low Weight at low material use, making it light and easy is inexpensive to produce.
Der Hohlraum in dem Lagerring oder in den Lagerringen ist dabei vorzugsweise abgeschlossen. Hierunter ist vorliegend zu verstehen, dass der Hohlraum beispielsweise durch einen Schweiß- oder Lötvorgang hermetisch abgeschlossen ist, so dass beispielweise keine Feuchtigkeit in das Hohlrauminnere eindringen kann. Dadurch kann Korrosion entgegengewirkt werden.Of the Cavity in the bearing ring or in the bearing rings is preferably completed. This is to be understood in the present case that the cavity for example, hermetically sealed by a welding or soldering process is so that, for example, no moisture penetrate into the cavity interior can. As a result, corrosion can be counteracted.
Das Blechteil, aus dem die Lagerringe gebildet werden, hat vorzugsweise eine konstante Dicke.The Sheet metal part from which the bearing rings are formed, preferably a constant thickness.
Es kann dabei vorgesehen werden, dass der Innenring und/oder der Außenring aus einem einzigen Blechteil gebildet wird, dessen Enden an einer Stelle zusammentreffen und dort miteinander verbunden sind.It can be provided that the inner ring and / or the outer ring is formed from a single sheet metal part, whose ends in one place meet and are connected together.
Alternativ hierzu kann der Innenring und/oder der Außenring auch aus zwei Blechteilen gebildet sein, die an zwei Stellen zusammentreffen und dort miteinander verbunden sind. Diese Verbindung ist bevorzugt durch Stoffschluss hergestellt. Dabei hat sich insbesondere das Schweißen, insbesondere das Laserschweißen oder das Elektronenstrahlschweißen, als Verbindungsverfahren bewährt. Genauso kann aber auch Löten, insbesondere Hartlöten, hierfür eingesetzt werden.alternative For this purpose, the inner ring and / or the outer ring also formed from two sheet metal parts be, which meet in two places and connected there are. This compound is preferably produced by material adhesion. In particular, the welding, in particular laser welding or the electron beam welding, proven as a connection method. In the same way, brazing, especially brazing, therefor be used.
Das Blechteil des Innenrings ist bevorzugt so ausgeformt, dass es einen axialen Anschlag für die Kegelrollen bildet. Alternativ hierzu kann ein Anlaufbord für den axialen Anlauf der Kegelrollen auch am Blechteil des Außenrings ausgebildet sein.The Sheet metal part of the inner ring is preferably formed so that there is a axial stop for forms the tapered rollers. Alternatively, a starting board for the axial Start of the tapered rollers also be formed on the sheet metal part of the outer ring.
Eine Weiterbildung sieht vor, dass der Hohlraum zumindest einer der Lagerringe mit einer Füllung versehen ist, die ihn weitgehend, vorzugsweise vollständig, ausfüllt. Dabei kann zumindest einer der Lagerringe mindestens eine Einfüllöffnung zum Einbringen der Füllung aufweisen. Diese Einfüllöffnung kann im seitlichen Bereich der Lagerringe angeordnet werden; sie sollte nicht im Bereich der Laufbahnen liegen.A Further development provides that the cavity of at least one of the bearing rings with a filling is provided, which him largely, preferably completely, fills. there can at least one of the bearing rings at least one filling opening for Introducing the filling exhibit. This filling hole can be arranged in the lateral region of the bearing rings; she should not in the field of careers.
Die Füllung des Lagerrings kann dazu dienen, die mindestens zwei Teile eines mehrteilig (zweiteilig) ausgebildeten Lagerrings miteinander zu verbinden, d. h. es können beispielsweise ein Außenblechteil und ein Innenblechteil, die den Lagerring zusammen bilden, durch die Füllung zusammengehalten werden.The filling of the bearing ring can serve to at least two parts of a multi-part (two-piece) trained bearing ring to connect with each other, d. H. it can for example, an outer sheet metal part and an inner sheet metal part forming the bearing ring together the filling held together.
Die Füllung des Lagerringes oder der Lagerringe kann aus Metallpulver bestehen. Dabei sieht eine bevorzugte Ausgestaltung vor, dass das Metallpulver durch einen Härtevorgang der Lagerringe gesintert ist. Danach wird also vor dem Härtevorgang der Hohlraum des Lagerrings mit Metallpulver gefüllt und beim anschließenden Härten dieses gesintert.The filling of the bearing ring or the bearing rings may consist of metal powder. In this case, a preferred embodiment provides that the metal powder ge by a hardening process of the bearing rings is sintering. Thereafter, so before the hardening process, the cavity of the bearing ring is filled with metal powder and sintered during subsequent hardening of this.
Die Füllung kann auch aus Kunststoff bestehen. Weiterhin kommt eine Füllung mit Leichtmetall, insbesondere mit Aluminium oder mit einer Aluminiumlegierung, in Frage.The filling can also be made of plastic. Furthermore, a filling comes with Light metal, in particular with aluminum or with an aluminum alloy, in question.
Die Lagerringe bestehen bevorzugt aus Stahlblech. Sie können durch einen Tiefziehvorgang, durch einen Kaltwalzvorgang, durch einen Drückwalzvorgang, durch einen Rolliervorgang und/oder durch einen Fließpressvorgang hergestellt werden. Ferner können sie einer Wärmebehandlung, insbesondere einem Härtevorgang, möglicherweise unter Schutzgas, unterzogen werden. Bevorzugt weisen die Lagerringe eine Oberflächenhärte von mindestens 50 HRC auf.The Bearing rings are preferably made of sheet steel. You can go through a deep drawing process, by a cold rolling process, by a Flow-forming process, by a rolling process and / or by an extrusion process getting produced. Furthermore, can a heat treatment, in particular a hardening process, possibly under inert gas. Preferably, the bearing rings a surface hardness of at least 50 HRC.
