Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein einbaufertiges Wälzlager, dessen einstückig ausgebildeter Lageraußenring von einem zweiteiligen Lagergehäuse aufgenommen ist, dessen Gehäusehälften durch eine Ebene voneinander getrennt sind.The The invention relates to a ready-to-mount roller bearing whose integrally formed Bearing outer ring from a two-piece bearing housing is taken, the housing halves through a plane are separated from each other.
Hintergrund der ErfindungBackground of the invention
Zweiteilige Gehäuse zur Aufnahme von Lagern werden immer dann verwendet, wenn dies aufgrund der zu lagernden Teile erforderlich ist. Ein Anwendungsfall für ein solch geteiltes Gehäuse ist die Verwendung von gekröpften Wellen, beispielsbeweise die Lagerung von Kurbelwellen bei Brennkraftmaschinen. Die einzelnen Bestandteile sind Wellenzapfen, Hubzapfen und Wangen, wobei die Wellenzapfen in Grundlagern laufen und die Drehachse der Kurbelwelle definieren. Die Hubzapfen, die die Schubstangen (Pleuel) aufnehmen, beschreiben im Betrieb eine Kreisbahn um die Drehachse. Schließlich als letzter Bestandteil die Wangen, die die Hubzapfen mit den Wellenzapfen verbinden. Je nach dem wie oft die Welle gekröpft ist, d. h., je nach dem mit wie vielen Pleuel sie in Wirkverbindung steht, ist diese über mehrere voneinander beabstandete Grundlager gehalten.two-piece casing for storing bearings are always used if this is due the parts to be stored is required. An application for such a split housing is the use of cranked Waves, for example, the storage of crankshafts in internal combustion engines. The individual components are shaft journals, crank pins and cheeks, the shaft journals running in basic bearings and the axis of rotation of the crankshaft define. The crank pins, which receive the push rods (connecting rods), describe a circular path around the axis of rotation during operation. Finally as last part of the cheeks, the crank pin with the shaft journal connect. Depending on how often the shaft is cranked, d. h., depending on the with how many connecting rods she is in operative connection, this is about several held spaced apart basic camp.

Nun hat man zwar versucht zusätzliche axiale Sicherungen in das Gehäuse, beispielsweise Halteelemente, zu integrieren. Diese erhöhen aber einerseits den Fertigungsaufwand beim Lager und in der Lagerumgebung und verursachen andererseits u. U. einen Verlust von Lagerbreite.Now one has tried additional axial fuses in the housing, For example, holding elements to integrate. These increase but on the one hand, the production costs for the warehouse and in the warehouse environment and on the other hand cause u. U. a loss of storage width.
Zusammenfassung der ErfindungSummary of the invention
Ausgehend von den Nachteilen des bekannten Standes der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine sichere axiale Fixierung eines solchen Wälzlagers, das zur Aufnahme in einem zweiteiligen Gehäuse vorgesehen ist, ohne zusätzlichen Aufwand zu realisieren.outgoing from the disadvantages of the known prior art is the invention Therefore, the object of a reliable axial fixation of a such rolling bearing, which is intended for inclusion in a two-part housing, without additional To realize effort.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass der Lageraußenring beidseitig mit radial nach außen gerichteten Vorsprüngen versehen ist, die beide Gehäusehälften überdecken, wobei die Vorsprünge in axialer Richtung so voneinander beabstandet sind, dass zwischen diesen und den Gehäusehälften ein Spiel verbleibt. Das Spiel kann dabei sehr gering ausfallen oder auch über 1 mm liegen. Der Vorteil der letztgenannten Variante liegt darin, dass eine Vorpositionierung der Lagerringe zu den Gehäusehälften entfallen kann.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble in that the bearing outer ring on both sides with radially outward directed projections is provided, which cover both housing halves, the projections are spaced apart in the axial direction, that between this and the housing halves a game remains. The game can be very low or over 1 mm lie. The advantage of the latter variant is that a pre-positioning of the bearing rings can be omitted to the housing halves.
Der entscheidende Vorteil der erfindungsgemäßen Lösung liegt darin, dass eine hundertprozentige axiale Sicherung des Lageraußenringes gewährleistet ist, d. h., dieser ist unter allen Betriebsbedingungen an einem axialen Versatz gehindert. Dies ist insbesondere dann von Vorteil, wenn aufgrund des Einsatzes verschiedener Materialien, und damit auch verschiedener Wärmeausdehnungskoeffizienten, eine absolut sichere axiale Positionierung des Lageraußenringes gegeben sein muss. Durch die vorgeschlagene Lösung sind nach dem bisherigen Stand der Technik erforderliche Sicherheitsmaßnahmen, wie beispielsweise im Gehäuse vorgesehene Aussparungen, in die ein mit dem Lagerring verbundener Vorsprung eingreift, entbehrlich. Dies macht die Fertigung und die Montage des erfindungsgemäßen Lagers wesentlich einfacher.Of the decisive advantage of the solution according to the invention is that a 100% axial securing of the bearing outer ring guaranteed is, d. h., this one is under all operating conditions axial offset prevented. This is particularly advantageous if due to the use of different materials, and thus also different coefficients of thermal expansion, a absolutely safe axial positioning of the bearing outer ring must be given. The proposed solution according to the prior art technology required security measures, such as in the case provided recesses into which a connected to the bearing ring Advantage intervenes, dispensable. This makes the manufacturing and the Assembly of the bearing according to the invention much easier.
Weitere vorteilhafte Ausführungsvarianten der Erfindung sind in den Unteransprüchen beschrieben.Further advantageous embodiments of the Invention are in the subclaims described.
So geht aus den Ansprüchen 2, 3 und 4 die Ausgestaltung der radial nach außen gerichteten Vorsprünge hervor. Diese sollen als ein um 360° umlaufender Bord, als ein um 180° umlaufendes Bordsegment oder als beliebig geformte Laschen ausgebildet sein, die in Umfangsrichtung voneinander beabstandet sind.Thus, from the claims 2, 3 and 4, the embodiment of the radially outwardly directed projections. These are designed as a 360 ° encircling board, as a circulating around 180 ° Bordsegment or as any shaped tabs be formed, which are circumferentially spaced from each other.
Nach einem weiteren Merkmal der Erfindung ist nach Anspruch 5 vorgesehen, dass eine der Gehäusehälften mit einer Anlagefläche für die Vorsprünge versehen ist. Dadurch ist sichergestellt, dass die Anlagefläche für wenigstens einen in radialer Richtung nach außen gerichteten Vorsprung als Haltepunkt bzw. Wegbegrenzer dient, sodass der Lageraußenring zusätzlich gegen ein Verdrehen in Umfangsrichtung gesichert ist. Dies kann in besonders einfacher Weise derart realisiert werden, indem die Gehäusehälften in axialer Richtung eine unterschiedliche Breite aufweisen, sodass in der Trennebene eine Schulter gebildet ist.To a further feature of the invention is provided according to claim 5, that one of the housing halves with a contact surface for the projections is provided. This ensures that the contact surface for at least a radially outwardly directed projection as Breakpoint or Wegbegrenzer serves, so that the bearing outer ring additionally is secured against rotation in the circumferential direction. This can be realized in a particularly simple manner by the housing halves in axial direction have a different width, so that in the dividing plane a shoulder is formed.
Schließlich ist nach einem letzten Merkmal der Erfindung gemäß Anspruch 6 vorgesehen, dass das Wälzlager als ein spanlos geformtes Nadellager ausgebildet ist. Durch den weit fortgeschrittenen Stand der spanlosen Formgebung ist es möglich, derartige Nadellager in vielfältigen unterschiedlichen Formvarianten und Größenverhältnissen kostengünstig herzustellen, sodass jeder passende Anwendungsfall mit einem optimal ausgebildeten Wälzlager versorgt werden kann.Finally is provided according to a last feature of the invention according to claim 6, that the roller bearing is designed as a non-cutting shaped needle bearing. By the far advanced state of non-cutting shaping, it is possible such Needle roller bearings in diverse produce different shape variants and size ratios cost-effective, so that every suitable application with an optimally trained Supplied rolling bearings can be.
