Abstract

The invention represents a favourable possibility for the design of a machine with complete balancing of masses. It is an additional application to Patent Application P 3310416. With the aid of two counterweight shafts (20) it is possible completely to balance the first-order inertia forces, the following points having been taken into account: - the axes of the counterweight shafts (20) and of the crankshaft (7) should be parallel; - the distance of the counterweight shafts (20) from the crankshaft (7) should be equal for both counterweight shafts (20); - the centres of gravity of the counterweight shaft (20) and of the piston unit (2) should lie in a common plane perpendicular to the crankshaft axis; - the line connecting the axes of the counterweight shafts at their centre of gravity is perpendicular to the line of motion of the centre of gravity of the piston unit (2); - the two counterweight shafts (20) rotate in opposite directions; - the counterweight shafts (20) and the crankshaft (7) rotate at the same speed. Second- and higher-order effects of mass do not occur due to the use of the so-called Scotch-yoke mechanism. <IMAGE>

Description

BESCHREIBUNG DESCRIPTION

Arbeitsmaschine mit vollständigem Ausgleich der Massenwirkungen Die Erfindung ist eine Zusatzanmeldung zur Patentanmeldung P 33 10 416. Working machine with complete compensation of the mass effects Invention is an additional application to patent application P 33 10 416.

Im folgenden wird die Erfindung beisDielhaft von Zeichnungen näher erläutert. Es zeigen: Fig. 1 bis Fig. 4 die Stellungen der Gegenmassenwellen (20) relativ zur Kurbelwellenstellung, Fig. 5 in Diagrammform die Kraftkomponenten in x-Richtung, Fig. 6 in Diagrammform die KraftkomDonenten in z-Richtung.In the following the invention is illustrated by drawings explained. They show: Fig. 1 to Fig. 4 the positions of the counter-mass shafts (20) relative to the crankshaft position, FIG. 5 in diagram form the force components in x-direction, Fig. 6 in diagram form the force components in the z-direction.

Die Gegenmassenkräfte links Pl und rechts Fr sind gleich groß und entsprechen zusammen der Kolbenmassenkraft Fk. Die Achsen der Gegenmassenwellen (20) und der Kurbelwelle (7) sind parallel. Die Abstände AO und OB sind gleich lang. Die Gegenmassenwellen (20) haben entgegengesetzte Drehrichtungen.The counter-mass forces on the left Pl and on the right Fr are equal and together correspond to the piston mass force Fk. The axes of the counter mass waves (20) and the crankshaft (7) are parallel. The distances AO and OB are the same length. The counter mass shafts (20) have opposite directions of rotation.

Wenn die Kolbeneinheit (2) ihren obersten Punkt erreicht, wirkt eine Kolbenmassenkraft Fk in z-Richtung nach oben, die durch die nach unten gerichteten Kräfte Fl und Fr der linken und rechten Gegenmassenwellen (20) ausgeglichen wird (Fig.When the piston unit (2) reaches its uppermost point, a Piston mass force Fk in the z-direction upwards, which is caused by the downwards-directed Forces Fl and Fr of the left and right counter-mass shafts (20) is balanced (Fig.

1).1).

In der Mittelstellung der Kolbeneinheit (2) ist die Kolbenkraft Fk null, die Kräfte Fl und Fr der Geqenmassenwellen (20) heben sich gegenseitig auf (Fig. 2 und 4).In the middle position of the piston unit (2), the piston force Fk zero, the forces Fl and Fr of the geqenmassewellen (20) cancel each other out (Figures 2 and 4).

Geht die Kolbeneinheit (2) ganz nach unten, wirkt die Kolbenkraft Fk in z-Richtung wieder am stärksten, wie ebenfalls die beiden nach oben gerichteten Kräfte Fl und Fr der Gegenmassenwellen (20) (Fig. 3).When the piston unit (2) goes all the way down, the piston force acts Fk strongest again in the z-direction, as are the two upward-facing ones Forces Fl and Fr of the counter mass waves (20) (Fig. 3).

In x-Richtung treten nur die Kraftkomponenten der Gegenmassenwellen (20) in Sinus-Form in Abhängigkeit vom Kurbelwinkel auf. Diese Kraftkomponenten heben sich gegenseitia auf (Fig.Only the force components of the counter-mass waves occur in the x-direction (20) in sinus form as a function of the crank angle. These force components cancel each other out (Fig.

5).5).

In z-Richtung addieren sich die Kraftkomponenten der Gegenmassenwellen (20) und gleichen die in z-Richtung wirkende Kolbenkraft Fk aus (Fig. 6). Die Größe dieser Kräfte hängt vom Kurbelwinkel ab und ist sinusförmig.The force components of the counter-mass waves add up in the z-direction (20) and compensate for the piston force Fk acting in the z-direction (Fig. 6). The size of these forces depends on the crank angle and is sinusoidal.
