CUTTING ROLLER BEARING PART, CUTTING ROLLER HOLDER WITH CUTTING ROLLER BEARING PART, CUTTING WHEEL WITH CUTTING ROLLER HOLDER AND TUNNEL BORING MACHINE WITH CUTTING WHEEL

摘要

In a cutting roller bearing part (306) as a component of a cutting roller holder for a cutting wheel of a tunnel boring machine, a load measuring unit (612, 615) is arranged in a receiving space assembly (603, 606, 618, 621), which is hermetically sealed against the external atmosphere by external closures (509, 512, 515, 518, 521) and a sealing element (636) surrounding through-lines. In this way, a proportionally high level of accuracy and long-term stability is provided for load measurements.
