Description

Die Erfindung betrifft eine Anordnung von Anlaufscheiben für ein durch ein käfigloses Nadellager radial gelagertes Rad, insbesondere für Planetenräder von Kraftfahrzeugwechselgetrieben.The invention relates to an arrangement of thrust washers for a needle roller bearing without a cage Radially mounted wheel, especially for planetary gears of motor vehicle change transmissions.

Bei bestimmten Belastungsfällen tritt infolge des radialen Spieles der käfiglosen Lagernadeln ein Verschränken der Nadeln auf. Die Nadeln üben dabei axiale Kräfte aus und bohren sich in die seitlichen Wandflächen ein. Gleichzeitig treten unter dem Einfluß dieser axialen Kräfte an den Laufflächen der Anlaufscheiben Anfressungen auf. Die der Erfindung zugrunde liegende Aufgabe besteht darin, diese nachteiligen Erscheinungen zu beseitigen.In certain load cases, the cage-free bearing needles become entangled due to the radial play of the needles. The needles exert axial forces and drill into the lateral ones Wall surfaces a. At the same time occur under the influence of these axial forces on the running surfaces of the Thrust washers scoring. The object on which the invention is based is to counteract this disadvantage Eliminate phenomena.

Durch das Kegelrollenlager in der USA.-Patentschrift 2 734 787 ist es bekannt, an der größeren Stirnfläche der Kegelrollen zwei Anlaufscheiben aus dem gleichen Werkstoff und mit derselben Härte anzuordnen. Die eingangs erläuterten Probleme eines Nadellagers treten bei diesem bekannten Kegelrollenlager naturgemäß nicht auf. Für den äußeren Laufring dieses bekannten Lagers sind zudem keine Anlaufscheiben vorgesehen.Through the tapered roller bearing in U.S. Patent No. 2,734,787, it is known, on the larger Front face of the tapered rollers to arrange two thrust washers made of the same material and with the same hardness. The problems of a needle roller bearing explained at the beginning occur with this known tapered roller bearing naturally not on. In addition, there are no thrust washers for the outer race of this known bearing intended.

Für den äußeren Laufring in dem bekannten Wälzlager der britischen Patentschrift 258 128 ist je eine seitliche Anlaufscheibe vorgesehen. Die in einem Käfig geführten zylindrischen Wälzkörper können sich nicht verschränken. Dieses bekannte Lager konnte für die Erfindung keine Anregung geben.For the outer race in the known roller bearing of British Patent 258 128 is one lateral thrust washer provided. The cylindrical rolling elements guided in a cage can do not entangle. This known camp could not provide any suggestion for the invention.

Aus der USA.-Patentschrift 2 038 079 ist es bekannt, die Wälznadeln eines Radiallagers sowohl in seitlichen Käfigringen zu führen als auch diese Käfigringe selbst als Anlaufscheiben bzw. besondere Anlaufscheiben für die Wälznadeln vorzusehen. Auch bei diesem bekannten Lager mit einem Käfig für die Wälzkörper treten die der Erfindung zugrunde liegenden Probleme nicht auf.From US Pat. No. 2,038,079 it is known to use the rolling needles of a radial bearing in both To guide lateral cage rings as well as these cage rings themselves as thrust washers or special thrust washers to be provided for the pitch needles. Also in this known camp with a cage for the Rolling bodies do not have the problems on which the invention is based.

Schließlich ist durch die schweizerische Patentschrift 39 085 bei Wellenlagern noch die Verwendung von mehreren konzentrisch ineinander angeordneten Gleitlagerschalen bekannt, die aus demselben Werkstoff oder aus verschiedenen Werkstoffen bestehen können.Finally, through the Swiss patent specification 39 085, shaft bearings are still used known from several concentrically nested plain bearing shells made of the same material or can consist of different materials.

Zur Lösung der oben geschilderten Erfindungsaufgabe wird gemäß der Erfindung bei einer Anordnung von Anlaufscheiben für ein durch ein käfigloses Nadellager radial gelagertes Rad, insbesondere für Planetenräder von Kraftfahrzeugwechselgetrieben, vorgeschlagen, daß jeweils mindestens zwei aneinander gleitende schwimmende Anlaufscheiben unterschiedlicher Härte an beiden Radstirnseiten vorgesehen sind, von denen die härteren, deren Härte der der Nadeln angepaßt ist, dem Rad unmittelbar benachbart sind und auch als Anlaufscheiben für die Nadeln dienen.In order to achieve the object of the invention described above, according to the invention, in an arrangement of thrust washers for a wheel supported radially by a cage-free needle bearing, in particular for planetary gears of motor vehicle change transmissions, it is proposed that at least two of each other sliding floating thrust washers of different hardness provided on both wheel front sides are, of which the harder, whose hardness is adapted to that of the needles, immediately adjacent to the wheel and also serve as thrust washers for the needles.

Durch die Verwendung von gleitgünstigen Anlaufscheiberi, insbesondere aus weichem Lagermetall, ist das Auftreten von Anfressungen vermieden, während die härteren, 'vorteilhafterweise aus Federstafil bestehenden Anlaufscheiben für das Rad gleichzeitig das Eindringen der Nadelköpfe in das weiche Lagermaterial verhindern.Through the use of slidable thrust washers, especially made of soft bearing metal, the occurrence of pitting is avoided while the harder, 'advantageously consisting of spring steel thrust washers for the wheel at the same time prevent the needle heads from penetrating the soft bearing material.

Wie die erfindungsgemäße Anordnung von Anlaufscheiben im einzelnen ausgeführt sein kann, ist im folgenden an Hand des in der Zeichnung dargestellten Ausführungsbeispieles für eine Planetenradlagerung erläutert. In der Zeichnung bedeutetHow the inventive arrangement of thrust washers can be carried out in detail is shown in following with reference to the embodiment shown in the drawing for a planetary gear bearing explained. In the drawing means

F i g. 2 shows section A in FIG. 1 on an enlarged scale.

Ein Planetenrad 1 ist über Wälznadeln 2 und einen Planetenradbolzen 3 am Planetenradträger 4 mit axialem Spiel gelagert. Der Planetenradbolzen 3 ist an seinen Enden in je eine Bohrung 5 bzw. 6 desA planet gear 1 is connected to the planet gear carrier 4 via roller needles 2 and a planet gear pin 3 axial play stored. The planet gear pin 3 is at its ends in a hole 5 and 6 of the

so Planetenradträgers 4 eingesetzt und mittels Aufdornen starr am Planetenradträger 4 befestigt. Zwischen Planetenradträger 4 und Planetenrad 1 sind jeweils weiche Anlaufscheiben 7 schwimmend auf dem Planetenradbolzen 3 angeordnet. Zwischen den weichen Anlaufscheiben 7 und dem Planetenrad 1 sind je eine harte Anlaufscheibe 8 ebenfalls schwimmend auf dem Planetenradbolzen 3 gelagert. Die harten Scheiben 8 dienen als Anlauf sowohl für das Rad 1 als auch für die Wälznadeln 2. Durch diese Anordnung ist in einfacher Weise vermieden, daß an den Laufflächen der Scheiben 7 und 8 Anfressungen auftreten und daß sich die Wälznadeln 2 in die seitlichen Wandflächen bohren.so planetary gear carrier 4 is used and by means of mandrels rigidly attached to the planet carrier 4. Between the planetary gear carrier 4 and the planetary gear 1 are each soft thrust washers 7 are arranged floating on the planet gear pin 3. Between the soft Thrust washers 7 and the planetary gear 1 are each a hard thrust washer 8 also floating on the Planet pin 3 mounted. The hard disks 8 serve as a start for both the wheel 1 and for the roller needles 2. This arrangement avoids in a simple manner that on the running surfaces the disks 7 and 8 erosions occur and that the needles 2 in the lateral Drill wall surfaces.
