Roller cutter arrangement and cutting wheel equipped with said roller cutter arrangement

摘要

The invention relates to a roller cutter arrangement (7) for a cutting wheel of a tunneling machine, which comprises an interchangable pot (11), a bearing block (24) which is mounted in the interchangebale pot (11) such that it can move along a movement axis (20), and a roller cutter unit (23) which comprises at least one roller cutter (8) which is rotationally mounted in the bearing block (24) and which acts along a working axis (29). Said working axis (29) is inclined with respect to the movement axis (20) such that the roller cutter (8) of the roller cutter units (23) can be arranged closely adjacent to each other, in particular, in the central area of the cutting wheel.
