Abstract

The present invention relates in general to slurry wall cutters for cutting slurry walls in specialist foundation engineering. The invention relates in particular to the cutting wheel assembly for such a slurry wall cutter (1), comprising a rotationally drivable cutter hub (8) and a cutting wheel (3) which can be detachably fastened to the cutter hub for conjoint rotation. According to the invention, the cutting wheel and the cutter hub are clamped against one another at the end faces thereof and are interlockingly secured to one another in order to transmit the high operating forces non-frictionally or at least not only frictionally. According to the invention, the end faces of the cutting wheel and the cutter hub that can be placed against one another are provided with lateral teeth (16, 17) which mesh with one another for conjoint rotation. The meshing pair of lateral teeth allows the cutter hub and the cutting wheel to be interlockingly held relative to one another for conjoint rotation. At the same time, the end faces lying against one another can also transmit axial forces such that the cutting wheel is untiltably held in place.
