Description

Bei Sternmotoren, deren Zylinder so angeordnet sind, daß die Zylinder achsen in einer senkrecht zur Kurbelwellenachse stehenden Ebene liegen, ist es bekannt, die Pleuelstangen an einem gegenüber dem Kurbelzapfen drehbaren Lagerstück angreifen zu lassen und dieses Lagerstück an ein "Zwanglaufgetriebe anzuschließen, das ihm bei laufendem Motor gegenüber dem Kurbelzapfen eine Drehbewegung erteilt, die in der Größe .gleich, in der Richtung entgegengesetzt der Drehung der Kurbel gegenüber dem Motorgehäuse ist. Die Erfindung betrifft eine Verbesserung dieser Einrichtung, und zwar bezweckt sie die Vermeldung eines Druckwechsels im Getriebe des Lagerstückes. Erfindungsgemäß ist das Lagerstück so an das Getriebe angeschlossen, daß die Pleuelstangen-Angriffspunkte am Lagerstück in den Totpunktlagen der Kurbel gegenüber dem Kurbelradius um einen gewissen Winkel (von der Mitte des Lagerstückes aus gemessen) versetzt sind, und zwar in Richtung der Kurbeldrehung gegenüber dem Motorgehäuse.In radial engines, the cylinders of which are arranged so that the cylinder axes in one The connecting rods are known to lie perpendicular to the plane standing perpendicular to the crankshaft axis to attack on a bearing piece rotatable with respect to the crank pin and to connect this bearing piece to a "positive-action gearbox" that is available to him when the engine is running relative to the crank pin given a rotary movement that .equals in size, in the Direction opposite to the rotation of the crank with respect to the motor housing. the The invention relates to an improvement of this device, namely it aims to report a pressure change in the gearbox of the bearing piece. This is according to the invention Bearing piece connected to the gearbox that the connecting rod points of application on Bearing piece in the dead center positions of the crank compared to the crank radius by a certain amount Angle (measured from the center of the bearing piece) are offset, namely in the direction of crank rotation with respect to the motor housing.

Die Zeichnung zeigt schematisch ein Ausführungsbeispiel der Erfindung. Zwei Zylindern und 2' sind an einem nicht gezeichneten Gehäuse so befestigt, daß ihre Achsen radial zur Kurbelwelle 3 mit Kurbel 4 und Kurbelzapfen S verlaufen. Auf dem Kurbelzapfen 5 sitzt drehbar das Lager stück 6 mit den Gelenkaugen 7, an welchen die mit dem Kolben 9 verbundenen Pleuelstangen 8 angreifen. Durch ein besonderes, nicht gezeichnetes Getriebe wird das Lager stück 6 bei laufendem Motor gegenüber dem Kurbelzapfen so bewegt, daß jeder Punkt desselben einen Kreis von gleichem Durchmesser wie der Kurbelkreis beschreibt. Das Lagerstück 6 ist nun mittels seines Getriebes so an die im Sinne des Pfeiles α umlaufende Kurbel 4 angeschlossen, daß. bei Totpunktstellung der Kurbel 4 in bezug auf den Zylinder 2 der Anlenkpunkt 7 der Pleuelstange 8 dieses Zylinders um einen bestimmten Winkel β aus der Ebene der Kurbel 4 herausgedreht ist, und zwar in Richtung des Pfeiles a. Die Kolbenkraft P hat demnach das Bestreben, das Lagerstück in Richtung des Pfeiles b zu drehen. Das gleiche gilt bei passender Wahl des Winkels β für alle anderen Kurbelstellungen, so wirkt z.B. bei der gestrichelt gezeichneten Kurbelstellung die im unteren Zylinder 2' wirksame Kolbenkraft P', die über die Pleuelstange 8' zum Gelenk 7' des Lagerstücks übertragen wird, im gleichen Sinne. Die Folge ist, daß die das Lagerstück in ihrer Lage haltenden Getriebeteile stets nur nach einer Seite belastet sind und somit der schädliche und Geräusch erzeugende Druckwechsel im Getriebe des Lagerstücks vermieden ist. In der Zeichnung sind nur zwei einander diametral gegenüberliegende Zylinder gezeichnet und dementsprechend besitzt auch das gegenüber dem Kurbelzapfen drehbare Lagerstück nur zwei Pleuelstangen-Angriffspunkte; es ist aber ohne weiteres klar, daß die Zahl der Zylinder und dementsprechend auch der Pleuelstangen-Angriffspunkte eine beliebig größere sein kann.The drawing shows schematically an embodiment of the invention. Two cylinders 2 and 2 'are attached to a housing (not shown) in such a way that their axes run radially to the crankshaft 3 with crank 4 and crank pin S. On the crank pin 5, the bearing piece 6 sits rotatably with the hinge eyes 7, on which the connecting rods 8 connected to the piston 9 engage. By a special, not shown gear, the bearing piece 6 with the engine running relative to the crank pin is moved so that each point of the same describes a circle of the same diameter as the crank circle. The bearing piece 6 is now connected by means of its gear to the crank 4 rotating in the direction of the arrow α, that. at the dead center position of the crank 4 with respect to the cylinder 2, the articulation point 7 of the connecting rod 8 of this cylinder is rotated out of the plane of the crank 4 by a certain angle β, in the direction of arrow a. The piston force P therefore tends to rotate the bearing piece in the direction of arrow b. The same applies to all other crank positions if the angle β is appropriately selected; for example, in the crank position shown in dashed lines, the piston force P ' effective in the lower cylinder 2', which is transmitted via the connecting rod 8 'to the joint 7' of the bearing piece, has the same effect Senses. The result is that the gear parts holding the bearing piece in their position are always loaded on only one side and thus the harmful and noise-producing pressure change in the gear mechanism of the bearing piece is avoided. In the drawing, only two diametrically opposed cylinders are drawn and accordingly the bearing piece rotatable with respect to the crank pin also has only two connecting rod points of application; but it is immediately clear that the number of cylinders and, accordingly, also of the connecting rod points of application, can be as large as desired.
