Description

Bekannt sind einzapfige Kurbeltriebe, bei denen sich ein kubischer Gleitstein in einer Kurbelschleife oder im 'Maschinenkolben selbst auf und ab bewegt. Der kubische Gleitstein verlangt vier vollkommen parallel gearbeitete Gleitflächen mit genauen Abständen und eine vollkommen parallele Lage der Kurbel- bzw. Exzenterwelle zu diesen Gleitflächen, sonst sind Klemmungen und ein Heißlaufen des Kurbeltriebes unvermeidlich. Die Herstellung solcher Gleitflächen und der genaue Zusammenbau mit der Welle sind zeitraubend und teuer.Single-pin crank mechanisms are known, in which a cubic Slide block in a crank loop or in the 'machine piston itself moved up and down. The cubic sliding block requires four completely parallel sliding surfaces with precise distances and a completely parallel position of the crankshaft or eccentric shaft to these sliding surfaces, otherwise there will be jamming and overheating of the crank mechanism inevitable. The manufacture of such sliding surfaces and the exact assembly with the shaft are time consuming and expensive.

Es wurde gefunden, daß man alle diese Kachtc@ile vermeiden kann, wenn man dem Gleitstein eine zylindrische Form gibt. Eine derartige Ausbildung des Gleitst< ines bietet den Vorteil einfacher und billiger Herstellung des Gleitsteines auf der Drehbank. Das gleiche gilt von der zylindrischen Bohrung im Maschinenkolben.It has been found that one can avoid all of these cachets if the sliding block is given a cylindrical shape. Such a design of the sliding bar ines offers the advantage of simpler and cheaper production of the sliding block the lathe. The same applies to the cylindrical bore in the machine piston.

Als besondererVorteil des zylindrischen Gleitsteines ist der einfache Zusammenbau und der leichte Gang des Kurbeltriebes zu erwähnen. Diese Erkenntnis ergibt sich aus folgender Überlegung: Der einzapfige Kurbeltrieb besteht bekanntlich aus drei bewegten Maschinenelementen, nämlich der Kurbelwelle mit der Längsachse x, dem Gleitstein mit der Längsachse y und dem Maschinenkolben mit der Längsachse z. Diese drei Achsen bilden ein räumliches, rechtwinkliges Koordinatensystem, auf dessen Achsen Verschiebungen des Gleitsteines und des Maschinenkolbens stattfinden. Wenn infolge fehlerhafter Ausführung und Montage die rechten Winkel nicht genau stimmen, so laufen beim Erfindungsgegenstande dennoch der Kurbelzapfen im Gleitstein, der Gleitstein im Maschinenkolben und der Maschinenkolben im Maschinenzylinder klemmungsfrei, da sich der zylindrische Gleitstein um die y-Achse und der zylindrische Maschinenkolben um die z-Achse frei drehen und klemmungsfrei zu der .x-Achse einstellen können.A particular advantage of the cylindrical sliding block is that it is simple To mention assembly and the easy gear of the crank mechanism. This realization results from the following consideration: The single-peg crank mechanism is known to exist from three moving machine elements, namely the crankshaft with the longitudinal axis x, the sliding block with the longitudinal axis y and the machine piston with the longitudinal axis z. These three axes form a spatial, right-angled coordinate system whose axes displacements of the sliding block and the machine piston take place. If, as a result of incorrect workmanship and assembly, the right angles are not exactly are correct, the crank pin still runs in the slide block with the subject matter of the invention, the sliding block in the machine piston and the machine piston in the machine cylinder are jam-free, because the cylindrical sliding block is around the y-axis and the cylindrical machine piston Can rotate freely around the z-axis and adjust without jamming to the .x-axis.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Die Kurbelwelle r mit der Stirnkurbel 2 ist im Lagerkörper 3 gelagert und dieser am Zylinder ,l angeschraubt. Die Stirnkurbel 2 ist in dem zylindrischen Gleitstein 5 gelagert, der sich in der zylindrischen Bohrung 6 des Kolbens 7 bewegt. Die Stirnkurbel 2 erteilt dem Kolben 7 die Hubbewegung. Der Kolben 7 ist gegenüber (lern Steg 8 mit einem rechteckigen Ausschnitt für den Durchgang der Stirnkurbel 2 versehen. Die beiden Stirnflächen des Kolbens 7 können unmittelbar als Maschinenkolben wirken oder eine Kolbenstange mit besonderem Kolben oder einen Plunger aufnehmen.The subject of the invention is shown in the drawing, for example. The crankshaft r with the end crank 2 is mounted in the bearing body 3 and this screwed to the cylinder, l. The front crank 2 is in the cylindrical sliding block 5, which moves in the cylindrical bore 6 of the piston 7. The brow crank 2 gives the piston 7 the stroke movement. The piston 7 is opposite (learn web 8 provided with a rectangular cutout for the passage of the front crank 2. The two end faces of the piston 7 can act directly as machine pistons or accommodate a piston rod with a special piston or a plunger.
