Description
Sicherung gegen ein Herausfallen der Nadeln aus einem vollrolligen, käfiglosen Nadellager Die Erfindung bezieht sich auf eine in ein vollrolliges, käfigloses Nadellager eingesetzte Sicherung gegen Herausfallen der Nadeln aus einer die Außenlaufbahn bildenden, durch spanlose Formgebung aus Stahlblech hergestellten gehärteten Topfbüchse vor dem Zusammenbau des Lagers mit einem ,die Innenlaufbahn bildenden Zapfen, insbesondere Kreuzgelenkzapfen, die beim Aufschieben des Lagers auf den Zapfen durch diesen aus dem Bereich der Nadeln gedrückt wird.Protection against the needles falling out of a full complement, Cageless needle roller bearings The invention relates to a full complement, cageless bearing Needle bearing used protection against falling out of the needles from the outer raceway forming hardened cup liner made of sheet steel by non-cutting shaping before assembling the bearing with a pin forming the inner raceway, in particular Universal joint pin, which is made when the bearing is pushed onto the pin through this the area of the needles.
Bekannt ist es, bei einem vollrolligen, käfiglosen Nadellager als Sicherung gegen das Herausfallen der Nadeln aus dem Außenlaufring eine Kugel zu verwenden, die beim Einführen der Welle oder eines Zapfens aus dem Lager entfernt wird, also nicht Bestandteil des Lagers verbleibt. Diese Sicherung ist dann nicht anwendbar, wenn der Außenlaufring als Topfbüchse ausgebildet ist, deren Boden das Ausschieben der Kugel verhindert. Die Anwendung von Lagern mit als Topfbüchse ausgebildetem Außenlaufring ist aber dann besonders vorteilhaft, wenn das Lager nicht nur radiale, sondern auch axiale Kräfte des Zapfens aufzunehmen hab, weil der Topfbüchsenboden die Funktion eines Axiallagers übernehmen kann. Um hierfür günstige Bedingungen zu schaffen, ist es bekannt, zwischen Topfbüchsenboden und Zapfenstirnfläche eine Anlaufscheibe aus Kunststoff vorzusehen.It is known for a full complement, cageless needle roller bearing as Securing a ball against the needles falling out of the outer race use that removed when inserting the shaft or a journal from the bearing will not remain part of the camp. This backup is then not applicable if the outer race is designed as a cup liner, the bottom of which the Prevents the ball from being pushed out. The use of bearings with a cup sleeve The outer race is particularly advantageous when the bearing is not only radial, but also have to absorb axial forces of the pin, because the bottom of the can socket can take over the function of an axial bearing. In order for this to be favorable conditions to create, it is known to have one between the pot socket base and the pin face A plastic washer must be provided.
Die Erfindungsaufgabe besieht nun darin, eine Sicherung der eingangs genannten Art zu schaffen, die nach dem Zusammenbau des Lagers mit einem die Innenlaufbahn bildenden Zapfen selber zu einem Lagerteil wird. Dies wird erfindungsgemäß mit einer Kunststoffscheibe vom Durchmesser des inneren Nadelhüllkreises erreicht, die durch den Zapfen in eine Vertiefung des Topfbüchsenbodens hineingeschoben wird und dort als an sich bekannte Anlaufscheibe zur Aufnahme von Axialschubkräften des Zapfens verbleibt.The task of the invention is now to secure the initially called type to create the inner race after assembling the bearing with a forming pin itself becomes a bearing part. This is according to the invention with a Plastic disc reached by the diameter of the inner needle envelope circle the pin is pushed into a recess in the bottom of the pot liner and there as a thrust washer known per se for absorbing axial thrust forces of the pin remains.
Eine solche Sicherung verhindert nicht nur wirksam das Herausfallen der Nadeln aus dem Lager vor dem Lagereinbau, sondern ist deshalb, weil sie zusätzlich die Funktion einer an sich benötigten Anlaufscheibe erfüllt, besonders vorteilhaft. Sie macht andere bekannte Haltemittel, wie z. B. um die Nadelenden greifende Topfbüchsenteile, überflüssig und gestattet die Anwendung von billig herzustellenden, mit ebenen Stirnflächen versehenen Nadeln.Such a fuse not only effectively prevents falling out of the needles from the bearing before the bearing installation, but is because they are additional fulfills the function of a thrust washer required per se, particularly advantageous. It makes other known holding means, such as. B. to the needle ends gripping pot liner parts, superfluous and allows the use of inexpensive to manufacture, with flat end faces provided needles.
Nach einem weiteren Erfindungsmerkmal wird ein Kippen der Kunststoffscheibe dadurch verhindert, daß diese zentrisch auf einem Bolzen verschiebbar angeordnet ist, der seinerseits zentrisch am Boden der Topfbüchse befestigt ist und beim Einbau des Lagers in einer Axialbohrung des Zapfens aufgenommen wird.A further feature of the invention is tilting the plastic disc prevents this from being arranged centrically on a bolt is, which in turn is attached centrally to the bottom of the pot liner and during installation of the bearing is received in an axial bore of the journal.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel.The drawing illustrates an embodiment.
F i g. 1 zeigt einen Längsschnitt durch ein Nadellager im Lieferzustand; F i g. 2 zeigt ebenfalls im Längsschnitt das in ein Gabelauge eingebaute Nadellager mit eingesetztem Kreuzkopfzapfen.F i g. 1 shows a longitudinal section through a needle roller bearing in the delivery state; F i g. 2 also shows, in longitudinal section, the needle bearing installed in a fork eye with inserted cross head pin.
Das in F i g. 1 im Lieferzustand, d. h. in verkaufsmäßiger Montage dargestellte Nadellager weist eine die Außenlaufbahn bildende, aus Stahlblech gezogene Topfbüchse 1 auf, deren Boden 2 mit einer kreisförmigen Vertiefung 3 versehen ist. Der äußere Rand 4 der Topfbüchse 1 ist nach innen umgelegt und bildet wie der Bodenrand 2' auf der anderen Seite eine axiale Anlauffläche für die ebenen Stirnenden der Nadeln 5.The in Fig. 1 in delivery condition, d. H. in sales assembly The needle roller bearing shown has an outer raceway that is drawn from sheet steel Pot liner 1, the bottom 2 of which is provided with a circular recess 3. The outer edge 4 of the pot liner 1 is folded inward and forms like the bottom edge 2 'on the other hand, an axial contact surface for the flat front ends of the Needles 5.
In der Vertiefung 3 ist im Betriebszustand des Lagers eine Kunststoffscheibe 6 aufgenommen, die als Anlaufscheibe für die Stirnfläche des Kreuzgelenkzapfens Z dient (s. F i g. 2). Die Kunststoffscheibe 6 hat einen solchen Außendurchmesser, daß sie mit festem Sitz in den inneren Hüllkreis der Nadeln 5 eingesetzt werden kann und bei einer Anordnung etwa im Bereich der Nadelmitte;-- wie F i g. 1 zeigt, ein Herausfallen der Nadeln 5 sicher verhindert.In the recess 3 is a plastic disc when the bearing is in operation 6 added as a thrust washer for the end face of the universal joint pin Z serves (see Fig. 2). The plastic disk 6 has such an outer diameter, that they are used with a tight fit in the inner enveloping circle of the needles 5 can and with an arrangement approximately in the area of the middle of the needle; - as in FIG. 1 shows the needles 5 are reliably prevented from falling out.
Um zu verhindern, daß die relativ dünne Kunststoffscheibe 6 um ihren Mittelpunkt kippt, wodurch ein Teil der Nadeln 5 herausfallen könnte, ist die Kunststoffscheibe 6 bei dem gezeigten Ausführungsbeispiel auf einem kurzen Bolzen 7 verschiebbar angeordnet. Der Bolzen 7, der z. B. aus Kunststoff besteht, ist am Boden 2 der Topfbüchse 1 auf einer angeprägten Warze 8 zentrisch befestigt. Beim Einbau des Lagers wird der Bolzen 7 in einer axialen Sacklochbohrung Z' des Kreuzgelenkzapfens Z aufgenommen, wo er ohne Schaden für die Lagerung verbleiben kann.In order to prevent the relatively thin plastic disc 6 around their The center of the tilting point, as a result of which part of the needles 5 could fall out, is the plastic disc 6 arranged displaceably on a short bolt 7 in the embodiment shown. The bolt 7, the z. B. consists of plastic, is on the bottom 2 of the pot liner 1 attached centrally on an embossed wart 8. During installation of Bearing is the bolt 7 in an axial blind hole Z 'of the universal joint pin Z added, where it can remain for storage without damage.
Durch die in dem Boden 2 der Topfbüchse vorgesehene Vertiefung 3 wird gleichzeitig eine Versteifung des Bodens erzielt, so daß die Durchbiegung unter der Einwirkung der Axialvorschubkräfte des Kreuzgelenkzapfens wesentlich verringert wird.Through the recess 3 provided in the bottom 2 of the pot liner at the same time a stiffening of the floor is achieved, so that the deflection under the effect of the axial feed forces of the universal joint pin is significantly reduced will.
Das Nadellager gemäß F i g. 1 wird von außen in die Bohrung des Gabelkopfes G eingepreßt. Dabei schiebt der Kreuzgelenkzapfen Z die Kunststoffscheibe 6 in die Vertiefung 3 hinein, und gleichzeitig tritt der kurze Bolzen 7 in die Bohrung Z' des Zapfens Z ein. Das Lager wird im Gabelkopf G durch einen eingesprengten Ring S gehalten.The needle bearing according to FIG. 1 is inserted into the hole in the clevis from the outside G pressed in. The universal joint pin Z pushes the plastic disk 6 into the Well 3 into it, and at the same time the short bolt 7 enters the hole Z ' of the pin Z a. The bearing is in the fork head G by a blown ring S held.
