Description
Einrichtung zur Verhinderung der axialen Verschiebung von zylindrischen Körpern mit einem konisch verjüngten Ende in ihnen als Lager dienenden Bohrungen. Gegenstand vorliegender Erfindung ist eine Einrichtung zur Verhinderung der axia len Verschiebung von zylindrischen Körpern mit einem konisch verjüngten Ende in ihnen als Lager dienenden Bohrungen, bei welcher ein offener, unrunder Federring vorgesehen ist, der zum Teil in eine am zylindrischen Körper vorgesehene Ringnute ragt und zum Teil in eine dieser Ringnute gegenüber liegende, tiefere Ringnute in der Bohrung.
In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstan- des dargestellt. Es zeigen: Fig. 1 einen geschlossenen, gegabelten Pleuelstangenkopf, in welchem der Kreuz kopfbolzen in Lagerbuchsen gelagert ist, im Grundriss, Fig. 2 einen Aufriss hierzu, Fig. 3 eine Seitenansicht einer Lager buchse, Fig. 4 eine Vorderansicht einer Lager buchse, Fig. 5 eine Ansicht.
eines unrun.den Feder ringes und Fig. 6 eine Ansicht einer Ausführungs variante des unrunden Federringes.
Nach Fig. 1 und 2 ist in einem geschlos senen, gegabelten Pleuelstangenkopf 1 der Steg 2 eines Kreuzkopfes mittels des Kreuz kopfbolzens 3 drehbar. In die Bohrungen der beiden Schenkel des Pleuelstangenkopfes 1 sind Lagerbuchsen 4 eingesetzt, in welchen der Kreuzkopfbolzen 3 gelagert ist. Die Lagerbuchsen 4, welche an ihrem einen Ende eine konische Andrehung 5 besitzen, weisen an ihrer zylindrischen Aussenfläche eine Ring nute 6 auf.
In den Bohrungen der beiden Schenkel. des Pleuelstangenkopfes 1 sind tie fere Ringnuten 7 eingearbeitet, und zwar in solcher Lage, dass sie, wenn die Lagerbuchsen 4 in richtiger Lage sieh befinden, genau den Ringnuten 6 gegenüberliegen. In diese Ring nuten 6 und 7 ist ein offener, ovaler Feder ring 8 eingesetzt, wie in Fig. 5 dargestellt. Es könnte auch ein gewellter Federring, wie in Fig. 6 damgestellt Lund mit 8' bezeichnet, eingesetzt sein. Der Federring 8 ist so ge formt, da.ss er, wenn er vor dem.
Einsetzen der Lagerbuchse 4 in die Ringnute 7 eingelegt wird, stellenweise in die Bohrung im Sehen kel des Pleuelstangenkopfes 1 vorsteht. Wenn nun :die Lagerbuchse 4 mit der konischen An drehung 5 voran in diese Bohrung eingetrie ben wird, so wird der Federring 8 durch die konische Andrehung 5 in die Ringnute 7 zurückgedrückt.
Sobald jedoch die Ringnute 6 der Lagerbuchse 4 der Ringnute 7 in der Bohrung im Schenkel des Pleuelstangenkopfes 1 gegenüberliegt, springen die Teile des Federringes 8, die vorher in die Bohrung ragten, in die Nute 6 ein, so dass,die Lager buchse 4 unverrückbar in der Bohrung des Schenkels des Pleuelstangenkopfes 1 gehalten wird.
In gleicher Weise könnten auch am Kreuz kopfbolzen 3 und in der Bohrung des Steges 2 des Kreuzkopfes korrespondierende Ring nuten vorgesehen und ein unrunder, offener Federring in diese Ringnuten eingelegt sein.
Wenn keine besonderen Massnahmen ge troffen sind, kann die Fixierung der Lager buchse im Pleuelstangenkopf nur durch Zer störung der Lagerbuchse 4 :oder des Feder ringes 8 bzw. 8' gelöst werden. Die Einrich tung kann jedoch .auch so vorgesehen werden, dass die Fixierung lösbar ist, indem minde stens drei in die Ringnute 6 der Lagerbuchse mündende, radial gerichtete Löcher 9 (Fig. 3 und 4) vorgesehen werden, welche es ermög lichen, mit einem Werkzeug den Federring 8 bzw. 8' in die Ringnute in der Bohrung zu rückzudrücken. Diese radial gerichteten Löcher, von .denen die Buchse nach Fig. 3 und 4 drei besitzt., können gleichzeitig als Schmierlöcher dienen.
Diese beschriebenen Einrichtungen zur Verhinderung der axialen Verschiebung von zylindrischen Körpern mit einem konisch ver jüngten Ende in ihnen als Lager dienenden Bohrungen zeichnen sich durch grösste Zuver lässigkeit aus, und sie eignen sich deshalb ins besondere auch für die Sicherung von Lager buchsen, Bolzen und dergleichen, die, wie z. B. bei Fahrzeugen, starken Erschütterun gen, Vibrationen und Schlägen ausgesetzt sind. Die Sicherungswirkung bleibt sogar dann noch bestehen, wenn der unrunde Feder ring einmal brechen sollte.
Device for preventing the axial displacement of cylindrical bodies with a conically tapered end in bores serving as bearings. The present invention is a device for preventing the axia len displacement of cylindrical bodies with a conically tapered end in them serving as a bearing bores, in which an open, non-circular spring ring is provided, which protrudes in part into an annular groove provided on the cylindrical body and for Part in one of these annular grooves opposite, deeper annular groove in the bore.
The drawing shows an example of an embodiment of the subject matter of the invention. 1 shows a closed, forked connecting rod head in which the cross head bolt is mounted in bearing bushes, in plan, FIG. 2 is an elevation of this, FIG. 3 is a side view of a bearing bushing, FIG. 4 is a front view of a bearing bushing, Fig. 5 is a view.
a unrun.den spring ring and Fig. 6 is a view of an embodiment variant of the non-round spring ring.
According to Fig. 1 and 2, the web 2 of a cross head by means of the cross head bolt 3 is rotatable in a closed-end, forked connecting rod head 1. In the bores of the two legs of the connecting rod head 1, bearing bushings 4 are used, in which the cross head bolt 3 is mounted. The bearing bushes 4, which have a conical turning 5 at one end, have an annular groove 6 on their cylindrical outer surface.
In the holes of the two legs. of the connecting rod end 1 deeper annular grooves 7 are incorporated, in such a position that they are exactly opposite the annular grooves 6 when the bearing bushes 4 are in the correct position. In this ring grooves 6 and 7, an open, oval spring ring 8 is used, as shown in FIG. A corrugated spring ring, as shown in FIG. 6, Lund denoted by 8 ', could also be used. The spring ring 8 is shaped so that it da.ss when he is in front of.
Insertion of the bearing bush 4 is inserted into the annular groove 7, in places in the hole in the seeing angle of the connecting rod head 1 protrudes. If now: the bearing bush 4 with the conical rotation 5 ahead in this bore is eingetrie ben, the spring ring 8 is pushed back into the annular groove 7 by the conical turning 5.
However, as soon as the annular groove 6 of the bushing 4 of the annular groove 7 in the bore in the leg of the connecting rod head 1 is opposite, the parts of the spring ring 8 that previously protruded into the bore jump into the groove 6, so that the bearing bush 4 immovable in the bore of the leg of the connecting rod head 1 is held.
In the same way, on the cross head bolt 3 and in the bore of the web 2 of the cross head corresponding ring grooves could be provided and a non-circular, open spring ring could be inserted into these ring grooves.
If no special measures are taken, the fixation of the bearing bushing in the connecting rod head can only be solved by destroying the bearing bushing 4: or the spring ring 8 or 8 '. The device can, however, also be provided so that the fixation can be released by providing at least three radially directed holes 9 opening into the annular groove 6 of the bearing bushing (FIGS. 3 and 4), which make it possible to use one Tool to push the spring ring 8 or 8 'back into the annular groove in the bore. These radially directed holes, of which the bushing according to FIGS. 3 and 4 has three, can also serve as lubrication holes.
These described devices for preventing the axial displacement of cylindrical bodies with a conical ver tapered end in them serving as a bearing bores are characterized by the greatest reliability, and they are therefore particularly suitable for securing bearing bushings, bolts and the like, which, such as B. in vehicles, strong shock conditions, vibrations and shocks are exposed. The locking effect remains even if the non-circular spring ring should break.
