摘要

Disclosed is a device for monitoring the state of rotation of a disk cutter (5) of a shield tunnel boring machine (1). The device includes a housing (29, 30) which has at least one retaining space (48, 49, 50) for accommodating modules (33, 53, 54, 55, 56) and is configured for mounting on a clamping unit (15) designed for fastening a disk cutter axis (27) of the disk cutter (5). The retaining space (48, 49, 50) is closed on all sides, and the housing has a housing block (29) having the or each retaining space (48, 49, 50). The housing block (29) being provided with an elongated bushing base (44) as part of the fastening unit, which has a shaft channel (45) extending in the longitudinal direction of the bushing base (44) for accommodating a clamping screw shaft (38) of the clamping unit (15). The bushing base (44) is situated in the central area in the transverse direction of the housing block (29), and at least one retaining space (48, 49, 50) is provided on both sides of the bushing base (44).
