Description

Die Erfindung betrifft eine neue Lagerung für gekröpfte Wellen, insbesondere Kurbelwellen, die gegenüber dem bisherigen Stand der Technik bedeutende Vorteile aufweist. In der Zeichnung ist eine derartige Lagerung beispielsweise dargestellt, wobei Abb. i einen Ausschnitt einer Kuibelwelle schematisch darstellt und Abb. 2 eine Seitenansicht hiervon.The invention relates to a new bearing for cranked shafts, in particular Crankshafts, which have significant advantages over the previous state of the art having. In the drawing, such a storage is shown, for example, where Fig. i shows a section of a Kuibel shaft schematically and Fig. 2 a side view of this.

Ungeteilte, gekröpfte Wellen, nachgenannt Kurbelwellen, werden auf ihren Lagerstellen sehr genau geschliffen, worauf dann die Lagerschalen der Pleuellager aufgepaßt werden. Mit dem laufenden Betrieb der Kurbelwellen nutzt sich der Kurbelzapfen ab, wodurch eine Neulagerung erforderlich wird. Dies erfolgt durch erneutes Schleifen der Lagerflächen und Aufpassen neuer Pleuellager, die jeweils dem nachgeschliffenen Kurbelzapfen angepaßt werden müssen. Standardgrößen selbst nur für Pleuellager sind nicht möglich.Undivided, cranked shafts, referred to as crankshafts, are opened their bearings ground very precisely, whereupon the bearing shells of the connecting rod bearings be taken care of. With the ongoing operation of the crankshafts, the crank pin is used from which a new storage is necessary. This is done by grinding again the storage areas and taking care of new connecting rod bearings, each after the reground Crank pins need to be adjusted. Standard sizes themselves are only for connecting rod bearings not possible.

Die nachstehend beschriebgne Erfindung bezieht sich ausschließlich auf Lagerstellen gekröpfter Wellen, den sogenannten Kurbelwellen. Es ist zwar versucht worden, diese Lagerstellen durch Auffütterung nach Ablauf zu erneuern, doch sind hier neues Drehen und Schleifen erforderlich. Bei Kurbelwellenlagern aus Leichtmetall ist ein einwandfreies Auffüttern bislang nicht einwandfrei gelungen.The invention described below relates exclusively on bearings of cranked shafts, the so-called crankshafts. It is tried have been to renew these bearings by replenishing after expiry, but are new turning and grinding required here. For crankshaft bearings made of light metal flawless feeding has not yet been flawlessly successful.

Die vorliegende Erfindung beseitigt diese Nachteile restlos. Auf dem Kurbelzapfen i, der in seiner Breite ganz oder teilweise genaustens geschliffen ist, werden zwei oder mehr Zapfenschalen 2 (schwarz gezeichnet) aufgebracht, die in 3 geteilt sind. Diese Zapfenschalen werden auf dem Kurbelzapfen i wohl lösbar befestigt, jedoch so, daB sie sich während des Betriebs weder verdrehen noch sonstwie verrücken können. Diese Befestigung kann auf die verschiedenstq Art erfolgen, die hier nicht weiter erörtert werden soll. Auf dem äußeren Umfang dieser Zapfenschalen läuft das normale Pleuellager 4. Haben sich nun ein oder mehrere derartige Kurbelwellenlager ausgelaufen, dann werden auf dem Kurbelwellenzapfen i lediglich neue Zapfenschalen 2 befestigt und die Pleuellager erneuert, die beide normalisiert sind. Hierdurch ergibt sich die Möglichkeit, in kürzester Zeit z. B. einen Verbrennungsmotor neu zu lagern, da nur eine Auswechselarbeit anfällt, die jegliches Schleifen und Einpassen hinfällig macht. Wesentliche Arbeitszeit und Kosten werden erspart. Im Fall von Endzapfen einer Kurbelwelle werden Zapfenbüchsen 5 aufgezogen, die ungeteilt sind. Oben beschriebene Vorteile treffen auch hier in vollem Umfang zu.The present invention completely eliminates these disadvantages. On the Crank pin i, which is ground completely or partially in its width is, two or more peg shells 2 (drawn in black) are applied, the are divided into 3. These pin shells can be released on the crank pin i attached, but in such a way that they do not twist or otherwise during operation can move. This attachment can be done in a variety of ways shall not be discussed further here. On the outer circumference of these tenon cups runs the normal connecting rod bearing 4. You now have one or more such crankshaft bearings expired, then only new journal shells are placed on the crankshaft journal i 2 and renewed the connecting rod bearings, both of which are normalized. Through this there is the possibility of z. B. an internal combustion engine to store, as there is only one replacement work, which is any grinding and fitting makes obsolete. Significant working hours and costs are saved. In the case of End journals of a crankshaft are drawn on journal sleeves 5, which are undivided. The advantages described above also fully apply here.
