Verwendung der Lagerung nach einem der Ansprüche 1 bis 4 in einem Planetengetriebe, wobei das rotierende Maschinenteil (8) ein Planetenrad und der Lagerzapfen (4) der zugehörige Planetenrad-Bolzen ist.7. Use of the bearing according to any one of claims 1 to 4 in a planetary gear, wherein the rotating machine part (8) is a planet wheel and the bearing journal (4) is the associated planet wheel bolt. Die Erfindung bezieht sich auf die Lagerung eines Maschinenteils, wie sie im Oberbegriff des Patentanspruches 1 beschrieben ist.The invention relates to the mounting of a machine part as described in the preamble of patent claim 1. Bei der Lagerung von Maschinenteilen, die auf einem in der Regel bezüglich seiner Achse feststehenden Bolzen od. dgl. rotieren, wie z.B. Planetenräder, werden oftmals Gleitlager angewendet. Häufig handelt es sich dabei um Mehrflächengleitlager. Da die Lage des Profils dieser Lager zur Richtung der beispielsweise aus der Verzahnung herrührenden Kräfte konstant sein soll, ist es erforderlich, dieses Profil auf den feststehenden Teil, also die Welle od. dgl., aufzubringen. Die übliche Ausführung, bei der der feststehende Teil ganz oder teilweise aus einem Lagermetall, z.B. Bronze, gefertigt ist, hat den Nachteil, dass bei Erwärmung das Lagerspiel infolge des grösseren Ausdehnungskoeffizienten des Lagermetalls gegenüber Stahl verkleinert wird, wodurch weitere Erwärmung entsteht und somit wegen der dadurch bedingten weiteren La-gerspiel-Verkleinerung die Gefahr des Festfressens gegeben ist.Plain bearings are often used to mount machine parts that rotate on a bolt or the like that is generally fixed with respect to its axis, such as planet wheels. These are often multi-surface plain bearings. Since the position of the profile of these bearings should be constant in relation to the direction of the forces originating, for example, from the toothing, it is necessary to apply this profile to the fixed part, ie the shaft or the like. The usual design, in which the fixed part is made entirely or partially of a bearing metal, e.g. bronze, has the disadvantage that when the bearing metal heats up, the bearing clearance is reduced due to the greater coefficient of expansion of the bearing metal compared to steel, which causes further heating and thus because of the further bearing clearance reduction caused by this, there is a risk of seizing. Von daher liegt der Erfindung die Aufgabe zugrunde, eine Lagerung der im Oberbegriff beschriebenen Art zu erstellen,Therefore, the invention is based on the object of creating a bearing of the type described in the preamble, die sowohl die Vorteile der Mehrflächengleitlager aufweist als auch die Gefahr des Festfressens ausscheidet.which has both the advantages of multi-surface plain bearings and eliminates the risk of seizing. Diese Aufgabe wird mit einer Ausführung der Lagerung gelöst, die die Merkmale des Patentanspruchs 1 aufweist. Für die Ausgestaltung der Erfindung bieten sich einige günstige Möglichkeiten an, die in den Ansprüchen 2 bis 6 genannt sind.This problem is solved with an embodiment of the bearing that has the features of patent claim 1 . For the embodiment of the invention, there are a number of favorable options which are specified in claims 2 to 6. Weitere Vorteile und Einzelheiten der Erfindung gehen aus der folgenden Beschreibung hervor.Further advantages and details of the invention emerge from the following description. Anhand eines in den Figuren 1 und 2 dargestellten Ausführungsbeispiels wird die Erfindung nachstehend erläutert.The invention is explained below on the basis of an exemplary embodiment illustrated in FIGS. Es zeigenShow it Fig. 1 zwei Varianten eines Ausführungsbeispiels nach der Erfindung im Längsschnitt, undFig. 1 two variants of an embodiment according to the invention in longitudinal section, and Fig. 2 einen Querschnitt längs der Linie I-I.Figure 2 shows a cross-section along the line I-I. Ein nur z. T. dargestellter Planetenträger 1 nimmt in seinen Stegen 2,3 den Planetenradbolzen 4 auf, der beispielsweise mit einem Gewindestift 5 gegen Verdrehen und/oder axiales Verschieben gesichert ist. In seinem Mittelteil ist der Bolzen 4 mit einer bei Mehrflächengleitlager bekannten Profilierung versehen. In Fig. 2 sind als Ausführungsbeispiel vier Flächen 6 dargestellt. Es können — je nach den vorliegenden Betriebs-bedingungen- auch mehr oder weniger Flächen vorhanden sein, wie überhaupt die Gestaltung der nur vereinfacht dargestellten tragenden Partien 6 und der dazwischen liegenden Nuten 7 auch in anderer Form möglich ist. Auf dem profilierten Mittelteil ist der Bolzen 4 von dem Planetenrad 8,8' umgeben, dessen Bohrungsdurchmesser um das erforderliche Lagerspiel grösser ist als der Aussendurchmesser des Mittelteils des Bolzens 4. Im Bereich der Bohrung weist das Planetenrad 8 zur Verringerung der Gleitreibung eine Schicht 9 aus einem Werkstoff mit guten Gleiteigenschaften auf. Dieser Werkstoff kann entweder durch Ausgiessen oder Aufspritzen od. dgl. in einer verhältnismässig dünnen Schicht direkt auf die Wandung der Bohrung aufgebracht sein, oder in die Bohrung des Planetenrades 8' ist eine Büchse aus geeignetem Werkstoff eingesetzt. Auch das Einsetzen einer Stahlbüchse 10,A just z. T. shown planet carrier 1 takes in its webs 2.3 on the planet wheel 4, which is secured, for example, with a set screw 5 against rotation and / or axial displacement. In its central part, the bolt 4 is provided with a profiling known from multi-surface plain bearings. In Fig. 2 four surfaces 6 are shown as an embodiment. Depending on the operating conditions present, more or fewer surfaces can also be present, and the design of the load-bearing parts 6 (shown only in simplified form) and the grooves 7 lying between them is also possible in a different form. On the profiled middle part, the pin 4 is surrounded by the planet gear 8,8', the bore diameter of which is larger than the outside diameter of the middle part of the pin 4 by the required bearing clearance. In the area of the bore, the planet gear 8 has a layer 9 to reduce sliding friction a material with good sliding properties. This material can either be applied by pouring or spraying or the like in a relatively thin layer directly onto the wall of the bore, or a bush made of a suitable material is inserted into the bore of the planet wheel 8'. Also the insertion of a steel can 10, deren Bohrung mit einem entsprechenden Gleitwerkstoff 9' beschichtet ist, ist möglich. In jedem Fall ist der Gleitwerkstoff 9,9' mit dem gegenüber Stahl grösseren Ausdehnungskoeffizienten in der Bohrung des Planetenrades 8, 8', so dass eine Beeinträchtigung des Lagerspiels durch Wärmeausdehnung des Gleitwerkstoffes vermieden wird. Beiderseits des Planetenrades 8,8' sind an sich bekannte Anlaufscheiben 11,12 angeordnet, die mit ebenfalls bekannten Mitteln, z.B. im Planetenträger sitzenden Stiften 13 gegen Mitdrehen gehalten sind. Beispielsweise über eine Bohrung 14 im Steg 3 des Planetenträgers 1 sowie eine Ringnut 15 und Bohrungen 16,16', 16" im Bolzen 4 kann der Lagerung Schmieröl in Pfeilrichtung zugeführt werden.whose bore is coated with a corresponding sliding material 9' is possible. In any case, the sliding material 9, 9' is in the bore of the planet gear 8, 8' with the greater coefficient of expansion than steel, so that the bearing play is prevented from being impaired by thermal expansion of the sliding material. Known thrust washers 11, 12 are arranged on both sides of the planet wheel 8, 8', which are held against turning by means which are also known, e.g. pins 13 seated in the planet carrier. For example, via a bore 14 in the web 3 of the planetary carrier 1 and an annular groove 15 and bores 16, 16', 16'' in the pin 4, lubricating oil can be supplied to the bearing in the direction of the arrow. Auf das Sonnenrad und den Zahnkranz des Planetentriebes braucht, da sie für die Erfindung ohne Bedeutung sind, nicht eingegangen zu werden. Sie sind auch in Fig. 1 und 2 nicht dargestellt.The sun gear and the toothed ring of the planetary drive do not need to be discussed since they are irrelevant to the invention. They are not shown in FIGS. 1 and 2 either. 22 ss 1010 ISIS 2020 2525 3030 3535 4040 4545 5050 5555 BB 1 Blatt Zeichnungen1 sheet of drawings
