Description
Die Erfindung betrifft ein einseitig belastetes Lager, bestehend aus Lagerbüchse und Lagergehäuse, insbesondere ein Kolbenbolzenlager einer Zweitakt-Brennkraftmaschine.The invention relates to a unilaterally loaded bearing, consisting of Bearing bush and bearing housing, in particular a piston pin bearing of a two-stroke internal combustion engine.
Um bei Lagern mit eingesetzter Büchse eine plastische Verformung bei Erwärmung zu verhindern, ist bereits vorgeschlagen worden, die Büchse mit einer von einer Stirnseite zur anderen als offener Kanal durchgehenden Trennfuge zu versehen, die in kaltem Zustand der eingesetzten Büchse so weit klafft, daß sich die Büchse bei Erwärmung ungehindert in Umfangsrichtung dehnen kann. Die Ausbildung der Trennfuge als offener Kanal bei diesen bekannten Lagern-hat den Nachteil, daß einmal das während des Betriebes in die Fuge hinein abgestreifte Schmieröl ungehindert zu den Stirnseiten hin abfließen -bzw. von. einer Stirnseite zur anderen übertreten kann und sich außerdem die Schnittkanten der Fuge in Achsrichtung gegeneinander verschieben können. Bei dem erfindungsgemäßen Lager sind diese Mängel dadurch vermieden, daß der Verlauf der Trennfuge einer rechteckigen, in Längsrichtung der Lagerbüchse spielfreien, in Umfangsrichtung dagegen Spiel aufweisenden Verzahnung entspricht. Bei ausreichender Bemessung des Zahnspiels in Umfangsrichtung kann sich die Büchse in Umfangsrichtung genügend ausdehnen, doch ist weder in nennenswertem Ausmaß ein Öldurchtritt durch die Fuge von einer Stirnseite zur anderen zu befürchten, noch ist eine axiale Verschiebung der Schnittkanten in Achsrichtung gegeneinander möglich.In order to cause plastic deformation in bearings with an inserted bushing To prevent heating, it has already been proposed to equip the sleeve with a to provide a continuous separating joint from one face to the other as an open channel, which in the cold state of the inserted rifle gapes so wide that the rifle is can expand unhindered in the circumferential direction when heated. The formation of the parting line as an open channel in these known bearings has the disadvantage that once the during The lubricating oil stripped into the joint during operation is unhindered to the end faces to flow away -or. from. one face to the other can step over and moreover the cutting edges of the joint can move against each other in the axial direction. at the camp according to the invention, these shortcomings are avoided in that the course the parting line of a rectangular, backlash-free in the longitudinal direction of the bearing bush, in the circumferential direction, however, corresponds to toothing having play. With sufficient Dimensioning of the backlash in the circumferential direction can move the bushing in the circumferential direction expand sufficiently, but there is no oil passage through to any appreciable extent the joint from one end face to the other is to be feared, nor is there an axial displacement of the cutting edges against each other in the axial direction possible.
Es empfiehlt sich, die Lagerbüchse gegen Verdrehen im Lagergehäuse zu sichern, beispielsweise mittels einer im Lagergehäuse gehaltenen, mit einem Zapfen in eine Ausnehmung am Umfang der Büchse hineinragenden Schraube oder mittels an einer oder an beiden Stirnseiten des Lagers eingesetzter Kerbnägel, Schrauben oder Keile erfolgen.It is advisable to prevent the bearing bush from rotating in the bearing housing to secure, for example by means of a held in the bearing housing, with a pin protruding into a recess on the circumference of the bushing screw or by means of grooved nails, screws or inserted on one or both end faces of the bearing Wedges are made.
In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Lagers dargestellt.In the drawing is an embodiment of the invention Depicted bearing.
Abb. I stellt ein Kolbenbolzenlager einer Zweitakt-Brennkraftmaschine in der Draufsicht auf eine Stirnseite dar. Abb. 2 zeigt den Verlauf der Trennfuge des Lagers nach Abb.I in der Draufsicht auf die abgewickelte Büchse.Fig. I shows a piston pin bearing of a two-stroke internal combustion engine in a plan view of an end face. Fig. 2 shows the course of the parting line of the bearing according to Fig. I in a plan view of the unwound sleeve.
In Abb. I ist das Lagergehäuse mit 4 und die Lagerbüchse mit I bezeichnet. Die aus Schwermetall hergestellte Lagerbüchse I weist in dem Bereich, in dem sie infolge des Zweitaktbetriebes nicht belastet ist, eine parallel zur Lagerlängsachse verlaufende Trennfuge 2 auf und ist mit einer Schicht 3 aus Leichtmetall ausgekleidet. Die Büchse I wird nach Aufbringen der Lagerauskleidung 3 im Walzplattierungsverfahren in die richtige Form gebogen. Zur Sicherung der Lagerbüchse I gegen Verdrehen im Lagergehäuse 4 ist stirnseitig ein Kerbnagel 5 eingesetzt.In Fig. I, the bearing housing is designated with 4 and the bearing bush with I. The bearing bush I made of heavy metal points in the area in which it is not loaded due to the two-stroke operation, one parallel to the longitudinal axis of the bearing running parting line 2 and is lined with a layer 3 made of light metal. After the bearing lining 3 has been applied, the liner I is roll cladding bent into the right shape. To secure the bearing bush I against twisting in the Bearing housing 4, a grooved nail 5 is inserted on the front side.
Abb. 2 zeigt, wie die Schnittkanten der Trennfuge 2 nach Art einer, rechteckigen Verzahnung so ineinandergreifen, daß zwar eine Ausdehnung der Büchse in Umfangsrichtung noch möglich ist, sich dagegen die Schnittkanten in Achsrichtung nicht gegeneinander verschieben können.Fig. 2 shows how engage the cut edges of the joint 2 in the manner of a rectangular serration so that, while an expansion of the sleeve is still possible in the circumferential direction, the cut edges in the axial direction can not move against each other hand.
