Description

Massenausgieichapparat. Massenausgleichapparate für Maschinen mit hin und her gehenden Massen, insbesondere für Kolbenkraftmaschinen, die auf der Wirkung schwingender Massen beruhen, sind bekannt. Doch haben diese Apparate den Übelstand, daß bei Hin- und Rückgang die gleichen Massenkräfte frei werden, während durch die endliche Schubstangenlänge bei Kurbeltrieben diese Massenkräfte für Hin-und Rückgang verschieden sind, und zwar nennt man diese zusätzlichen Kräfte »Massenkräfte zweiter Ordnung«.Mass balancer. Mass balancing apparatus for machines with reciprocating masses, especially for reciprocating engines on the Effect of vibrating masses are known. But these devices have that The problem is that the same inertial forces are released when going back and forth while due to the finite length of the push rod in the case of crank drives, these inertia forces for reciprocating These additional forces are called »mass forces second order «.

Der Gegenstand der vorliegenden Erfindung besteht aus einer mit dem Maschinenfundament fest verbundenen Gleitbahn a und einem Kreuzkopf b, der entweder durch Exzenter c oder Kurbel von der Hauptwelle d angetrieben wird. Dieser Kreuzkopf wirkt mittels zweier Hebel e, die in Lenkern f gelagert sind, auf die Gewichte g, die auf diese Weise eine an sieh bekannte, .gegenläufige Bogenbewegung ausführen, wobei die horizontalen Fliehkräfte der beiden Gewichte sich aufheben und die vertikalen sich addieren. Das Neue besteht darin, daß man die Mittelstellung dieser Hebel e nicht horizontal, sondern gegen die Horizontale um einen Winkei geneigt wählt, desssen Größe von dem Verhältnis Schubstangewänge zu Hub abhängt, wodurch ein Ausgleich auch der Massenkräfte zweiter Ordnung erreicht wird.The object of the present invention consists of one with the Machine foundation firmly connected slideway a and a cross head b, which is either is driven by eccentric c or crank from the main shaft d. That crosshead acts by means of two levers e, which are mounted in links f, on the weights g, which in this way perform a well-known, opposing arching movement, whereby the horizontal centrifugal forces of the two weights cancel each other out and the vertical ones add up. The new thing is that you can adjust the middle position of these levers e not horizontally, but inclined at an angle to the horizontal Size depends on the ratio of pushrod to stroke, creating a balance second order inertia forces are also reached.

PATENT-ANSpRUcn: Massenausgleichapparat für Maschinen mit hin und her gehenden Massen., insbesondere Kolbenkraftmaschinen, bei welchem die umlaufende Bewegung der Hauptwelle durch Kurbel- oder Exzentertrieb auf einen Kreuzkopf übertragen wird, der mittels Schwinghebel zwei gegenläufige Gewichte in Bewegung setzt, dadurch gekennzeichnet, daß die Schwinghebel (e, e) in ihrer Mittellage gegen die Horizontale um einen solchen Winkel geneigt sind, daB die Massenkräfte zweiter Ordnung ausgeglichen sind. PATENT APPLICATION: Mass balancing apparatus for machines with reciprocating masses., In particular piston engines, in which the rotating movement of the main shaft is transmitted by crank or eccentric drive to a cross head which sets two counter-rotating weights in motion by means of a rocker arm, characterized in that the rocking levers (e, e) are inclined in their central position relative to the horizontal by such an angle that the inertial forces of the second order are balanced.
