Description

Es ist vielfach erforderlich, Wellen oder Kurbelwellen aus besonderen Gründen, sei es zum Zwecke des Einbaues von Wälzlagern oder aus anderen Gründen des Zusammenbaues, aus mehreren Einzelteilen herzustellen.It is often necessary to have special shafts or crankshafts Reasons, be it for the purpose of installing roller bearings or for other reasons of assembly, to be made from several individual parts.

Es sind dafür verschiedene Bauweisen bekannt, die aber entweder einen sehr schwierigen, mit äußerster Präzision verbundenen Herstellungsgang, z. B. Stirnverzahnung, haben oder aber nur einmaligen Zusammenbau und nur einfach gekröpfte Bauweisen gestatten.There are different construction methods known for this, but either one very difficult manufacturing process associated with extreme precision, e.g. B. spur gearing, have or only allow one-time assembly and only single cranked designs.

Bei der Ausführung nach dem Erfindungsgedanken wird ein an seinen Enden mit Einkerbungen oder Zähnen (z. B. durch Randrierung) versehener, gehärteter Wellen- oder Kurbelbolzen in die aus weicherem Baustoff bestehenden Kurbelwangen (Kurbelschenkel) eingeschlagen, wobei die Zähne oder Kerben in der etwas kleiner gehaltenen mittleren Wangenbohrung entsprechende konvexe Kerben herausscheren oder" eindrücken, so daß keine Präzision in der Herstellung der Bolzenzähne oder -kerben erforderlich ist. Mit einer geeigneten Vorrichtung ist es auf diese Weise möglich, eine beliebig lange Kurbelwelle herzustellen, die absolut schlagfrei läuft und die außerdem an jeder gewollten Stelle auseinandergenommen werden kann. Bei einem späteren nochmaligen Zusammensetzen muß jeder Zahn mit der von ihm vorher erzeugten Kerle wieder zusammenfallen, zumal eine 'kleine Versetzung, z. B. von einem Zahn, bei der laufen den Welle schon durch ein erhebliches Schlagen bemerkbar würde. Die Größe der Kerben, bzw. Zähne wird @so gewählt, daß sich ein absolut sicherer und zuverlässiger Sitz des Kurbelbolzens ergibt. Es ist damit auf einfachste Weise und ahne schwierige Bearbeitungsmaßnaihhmen eine Art des Zusammenbaues geschaffen, welche auch den schwierigsten Anforderungen gerecht wird.When executing according to the idea of the invention, an on his Hardened ends provided with notches or teeth (e.g. by edge grooving) Shaft or crank bolts in the crank webs made of softer building material (Crank arm) hammered in, the teeth or notches in the slightly smaller Shear out the corresponding convex notches held in the middle cheek hole or " so that there is no precision in the manufacture of the pin teeth or notches is required. With a suitable device it is possible in this way to produce a crankshaft of any length, which runs absolutely smoothly and which can also be taken apart at any desired point. At a later date Each tooth has to be reassembled with the fellows it had previously created collapse again, especially since a 'small displacement, z. B. from a tooth the running of the wave would already be noticeable by a considerable beating. The size the notches or teeth are chosen so that they are absolutely safe and reliable Seat of the crank bolt results. It is thus in the simplest way and, at first sight, difficult Machining measures created a type of assembly, which is also the most difficult Requirements.

Die Erfindung ist in den Abbildungen beispielsweise dargestellt.The invention is shown in the figures as an example.

Abb. i zeigt eine aus mehreren Einzelteilen zusammengebaute Kurbelwelle, bei welcher die Kurbelwangen als Lagerstellen ausgebildet sind. Es bezeichnen i den Antriebszapfen. 2 den Kurbelbolzen, 2a den gekerbten bzw. gezahnten Ansatz am Kurbelzapfen, 5 die Kurbelwange, 6, 7 und 8 die Unterlagscheibe, Sicherungsscheibe und Schraube zum axialen Festhalten des Kurbelbolzens.Fig. I shows a crankshaft assembled from several individual parts, in which the crank webs are designed as bearings. It denotes i the drive pin. 2 the crank bolt, 2a the notched or toothed approach on Crank pin, 5 the crank web, 6, 7 and 8 the washer, lock washer and screw for holding the crank bolt axially.

Abb.2 stellt ebenfalls eine zusammengesetzte Kurbelwelle dar, bei welcher jedoch die Lagerstellen in üblicher Weise als kurz eingebaute Wellenstücke ausgebildet sind. Die Teile sind wie in Abb. i bezeichnet. Die Ziffern 3 und ,4 kennzeichnen den mittleren bzw. Endlagerungsbolzen der Kurbelwelle.Fig.2 also shows a composite crankshaft, at which, however, the bearings in the usual way as briefly installed shaft pieces are trained. The parts are labeled as in Fig. I. Numbers 3 and 4 identify the central or end bearing pin of the crankshaft.

Abb. 3 zeigt in perspektivischer Darstellung das geza'hnte bzw. gekerbte Ende des Kurbel- bzw. Lagerbolzens.Fig. 3 shows a perspective view of the serrated or notched End of the crank or bearing pin.
