Abstract

Bei einem Mehrfachkurbeltrieb für Arbeitsmaschinen, insbesondere für Membranpumpen, mit einer in einem Gehäuse (2) angeordneten Kurbelwelle (1), die wenigstens zwei Lagerstellen (22, 23) aufweist, über einen Antrieb (24), insbesondere ein Getriebe, antreibbar ist, und ihrerseits jeweils über einen Kurbeltrieb (3, 4, 5) eine von mehreren Kolbenstangen (18, 19, 20) der Arbeitsmaschinen antreibt, ist die Anordnung derart getroffen, daß die Kurbelwelle (1) fliegend im Gehäuse (2) gelagert ist.

Figure 00000001
In a multiple crank drive for work machines, in particular for diaphragm pumps, with a crankshaft (1) arranged in a housing (2) and having at least two bearing points (22, 23), can be driven via a drive (24), in particular a gear, and in turn each one of a plurality of piston rods (18, 19, 20) of the working machines drives via a crank mechanism (3, 4, 5), the arrangement is such that the crankshaft (1) is overhung in the housing (2).
