Abstract
Description
Direkter Massenausgleich für Kolbenmaschinen Die Erfindung betrifft einen Massenausgleich für Kolbenmaschinen. Direct mass balancing for piston engines The invention relates to a mass balance for piston engines.
Der Zweck des Massenausgleichs ist die verschiedenen,durch oszillierende Teile erzeugten,Kräfte so auszugleichen,daß möglichst keine Vibrationen vom Motor aus auf andere Teile übertragen werden.The purpose of balancing the masses is different, by oscillating Parts generated to balance forces so that as little vibration as possible from the engine from being transferred to other parts.
Das im Folgenden beschriobene Verfahren wird im Gegensatz zum bisherigen Verfahren als direkter Massenausgleich",das bisherige erfahren als "indirekter Massenausgleich" bezeichnet.The procedure described below is in contrast to the previous one Procedure as direct mass balancing ", the previous experience as" indirect mass balancing " designated.
Die bisherige Methode des indirekten Massenausgleichs beruht auf folgendem Verfahren: Parallel zur Kurbelwelle werden weitere Ausgleichsvlellell,die mit gleicher oder doppelter Kreisfrequenz rotieren,eingebaut.The previous method of indirect mass balancing is based on the following Procedure: In parallel to the crankshaft, additional compensation layers are made with the same or double angular frequency, built-in.
An diesen Ausgleichswellen werden Gegengewichte angebracht,die dann Kräfte und Drehmomente erzeugen,die den unerwünschten Kräften und Momenten von Kurbelvelle,Pleuel und Kolben entgegenwirken. (Lit.: konstruktionsbücher des Springer-Verlags, z.B. G.H. Neugebauer, Kräfte in den Triebwerken schnellaufender Kolbenkraftmaschinen) Der konstrv.ktive aufwand dieses Verfahrens ist sehr grof und für den Serienbau kaum geeignet.Vrwirklicht wurde der indirekte Massenausgleich z.B. in Motor der Yamaha TX750- Der Erfindung liegt das Bemühen zugrunde diesen Aufwand zu verringern. Das Problem wird durch direkten Massenausgleich folgenderniaßen gelöst: 1.Der Kolben wird derart gebaut, daß sein Schwerpunkt mit seiner Drehachse um den Kolbenbolzen zusammenfällt.Counterweights are attached to these balance shafts, which then Generate forces and torques that counteract the undesired forces and moments of the crankshaft, connecting rod and pistons counteract. (Lit .: construction books from Springer-Verlag, e.g. G.H. Neugebauer, forces in the engines of high-speed piston engines) The constructive effort of this process is very great and for series production The indirect mass balancing was implemented e.g. in the engine of the Yamaha TX750- The invention is based on this effort to reduce. The problem is solved by direct mass balancing as follows: 1.The piston is built in such a way that its center of gravity is around the Piston pin collapses.
2.Am Pleuel wird ein Ausgleichsgewicht so angebracht,daß der Schwerpunkt des Systems: Kolben,Kolbenringe,Kolbenbolzen, Pleuellager, Pleuel und Ausgleichsgewicht mit der Drehachse um den Kurbelzapfen zusammenfällt.2. A balance weight is attached to the connecting rod in such a way that the center of gravity of the system: pistons, piston rings, piston pins, connecting rod bearings, connecting rods and counterweight coincides with the axis of rotation around the crank pin.
3.An der Kurbelwelle wird ein Ausgleichsgewicht so angebracht, daß der Schwerpunkt der Kurbelwelle und des obigen Systems ( (Kolben...) mit der Drehachse der Kurbelwelle zusammenfällt.3. A balance weight is attached to the crankshaft in such a way that the center of gravity of the crankshaft and the above system ((piston ...) with the axis of rotation the crankshaft collapses.
Dadurch wird erreicht, daß die Lage des Schwerpunkts der oszillierenden Teile unabhängig von der räumlichen stellung der einzelnen Teile ist. er Schwerpunkt ist immer in der Drehachse und dadurch werden keine @ ziehkräfte Ubertragen.This ensures that the position of the center of gravity of the oscillating Parts is independent of the spatial position of the individual parts. he focus is always in the axis of rotation and therefore no pulling forces are transmitted.
Der Vorteil der Erfindung liegt darin, das sich ein Slassenausgleich erzielen läftt,ohne die Anzahl der Bauteile zu erhöhen.The advantage of the invention is that there is a slave compensation can be achieved without increasing the number of components.
Lediglich durch das oszillerende Pleuel wird noch ein Drehmoment erzeugt,das sich beim bau von mehrzylindrigen Motoren vollständig ausleichen lä,.t.Only the oscillating connecting rod still generates a torque that can be completely compensated for when building multi-cylinder engines.
