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.
