Kurbelwelle für mehrzylindrige Verbrennungskraftmaschinen.Crankshaft for multi-cylinder internal combustion engines.
Patentiert im Deutschen Reiche vom 21. September 1918 ab.Patented in the German Empire on September 21, 1918.
1FUr die Serienfabrikation von Kurbelwellen für mehrzylindrige Verbrennungs- . ■ kraftmaschinen sind aus einem Stück hergestellte Kurbelwellen ' infolge der außerordentlichen Schwierigkeit ihrer Herstellung sowohl in der Schmiede als auch in der Dreherei und Schleiferei ungeeignet, und es ist daher vielfach der Versuch gemacht worden, diese Kurbelwellen aus mehreren Teilen 1 For the series production of crankshafts for multi-cylinder combustion engines. ■ Power machines are crankshafts made from one piece 'due to the extraordinary difficulty of their production in the forge as well as in the turning shop and grinding shop unsuitable, and many attempts have therefore been made to make these crankshafts from several parts
ίο zusammenzusetzen.ίο assemble.
Es sind insbesondere (mehrteilige Kurbelwellen bekannt, bei denen die einzelnen Teile durch konische Paßfläohen zusammengefügt sind. Dieser bekannten Ausfühnungsform gegenüber soll gemäß der .Erfindung die Kurbelwelle mit Flanschen ausgerüstet werden, auf denen die inneren Kugellagerlaufringe sitzen, und zwar mit einem solchen Durchmesser, daß die äußeren Kugellager ringe über die Kurlbälscheilben hinaus ragen, und daß die zusammengebaute Kurbelwelle samt den Kugellagern in das ungeteilte Kurbelgehäuse eingeschoben werden kann.There are in particular (multi-part crankshafts known in which the individual parts are joined together by conical fitting surfaces. Compared to this known embodiment the crankshaft is to be equipped with flanges according to the invention, on which the inner ball bearing races sit, with such a diameter, that the outer ball bearing rings protrude beyond the crank bellows, and that the assembled crankshaft including the ball bearings in the undivided crankcase can be inserted.
Die Herstellung der ebenen Paßflächen ist leichter und billiger als die konischer Paßfiächen und der Zusammenbau genauer. Ferner ergibt sich hierdurch eine geringere Baulänge des Motors und größere Festigkeit gegenüber Verwinidung und Verbiegung. Hieraus folgt wiederum ein ruhiger, erschütterungsfreier Gang der Maschine. Außerdem kann die so hergestellte mehrteilige Kurbelwelle im 'zusammengebauten Zustande samt den Kugellagern in der Achsrichtung in den Kurbelkasten eingefügt werden, wodurch eine Teilung dieses Kurbelkastens und die hierbei nötigen Verschraubungen entfallen können. Ferner können bei dieser Bauart normale, im Handel erhältliche Kugellager eingebaut werden. The production of the flat mating surfaces is easier and cheaper than the conical mating surfaces and the assembly more accurate. This also results in a shorter overall length of the motor and greater resistance to twisting and bending. This in turn results in a calm, vibration-free Gear of the machine. In addition, the multi-part crankshaft produced in this way can also be used in the assembled state the ball bearings are inserted in the axial direction in the crankcase, whereby a Division of this crankcase and the necessary screw connections can be omitted. Furthermore, normal, commercially available ball bearings can be installed in this design.
In Abb. ι und 2 der Zeichnung ist ein Ausführungsbeispiel dargestellt, bei dem jede Kurbel einen Bestandteil für sich bildet, und wobei diese Bestandteile untereinander völlig gleich sind. Es kann also auf diese Weise eine beliebige Anzahl von Kröpfungen durch Aneinanderreihung gleicher Bestandteile erzielt werden. Diese Anordnung bietet zugleich den Vorteil, daß in einfachster Weise, und ohne die Baulänge zu vergrößern, au jeder Kurbel eine Lagerung angeordnet werden kann. Die einzelnen Bestandteile der Kurbelwelle sind durch Schrauben aneinander befestigt, doch kann die Befestigung auch durch andere lösbare oder nicht lösbare Elemente erfolgen.In Fig. Ι and 2 of the drawing, an embodiment is shown in which each Crank forms a component in itself, and these components completely with one another are the same. In this way it can go through any number of cranks Stringing together the same components can be achieved. This arrangement offers at the same time the advantage that in the simplest way, and without increasing the overall length, au each Crank a storage can be arranged. The individual components of the crankshaft are attached to one another by screws, but the attachment can also be through other detachable or non-detachable elements take place.
Die Abb. 3 und 4 zeigen ein. anderes Ausführungsbeispiel, bei dem je zwei Kurbeln aus einem Stück bestehen. Plierbei entfällt nur auf je zwei Kurbelarme eine Lagerung.Figs. 3 and 4 show a. another embodiment, in which two cranks each consist of one piece. Plierbei is not applicable only one bearing on each two crank arms.
Die Anordnung bietet gegenüber der einteiligen Kurbelwelle den Vorteil· einer bedeutenden Verminderung der Torsion und der Torisionsischwi.mgunigen, weil die Baulänge bedeutend vermindert ist, unid weil ferner die elastischen Kurbelarme ersetzt sind durch ganz starre Scheiben, die der Torsion beträchtlichen Widerstand entgegensetzen. Hierdurch wird der Gang der Maschine namentlich in den höheren Tourenzahlen ruhig bleiben. Auch fallen bei zentrisch laufenden Kurbelscheiben ungünstige Massenwirkungen fort.Compared to the one-piece crankshaft, the arrangement offers the advantage of a significant Reduction of torsion and torsion barriers, because the overall length is significant is reduced, unid because, furthermore, the elastic crank arms are replaced by very rigid disks, which the torsion is considerable Oppose resistance. This makes the machine's course by name stay calm in the higher number of revolutions. Also fall with centrically running crank disks unfavorable mass effects continue.
