Abstract:
A housing mount assembly for a TBM disc cutter assembly having a shaft and cutter wheel assembly includes a housing half with a body and opposite edge portions extending away from the body. A removable seat block is fixed to the housing half in a space between the edge portions, and is configured to transmit forces received from the cutter shaft to the housing half in shear. A first face of the seat block is pressed against a face of one of the edge portions, and second face is pressed against the housing half body. The seat block may be preloaded against the housing half with first and second pluralities of bolts arranged perpendicularly. The seat block is configured to be removable in the field without removing the housing half from the TBM. The seat block may be hardened to a Rockwell C hardness in the range of Rc 58 to 60.

Claim (Index 13):
A housing mount assembly for mounting a disc cutter assembly to a tunnel boring machine, wherein the disc cutter assembly includes a shaft having first and second end portions, each end portion having a first seat surface, a second seat surface, and a third seat surface, the housing mount assemblies comprising:\n a housing half comprising a body portion, a first edge portion extending away from the body portion, and a second edge portion extending away from the body portion, wherein the body portion, the first edge portion, and the second edge portion cooperatively define a mounting space between the first and second edge portions; a removable seat block disposed in the mounting space and removably attached to the housing half such that a first face of the removable seat block is pressed against the first edge portion of the housing half, a second face of the removable seat block is pressed against the body portion of the housing half, and a seating face of the removable seat block is configured to engage the second seat surface of the associated end portion of the shaft; and a wedge lock assembly comprising a clamp block, a wedge member having a first face configured to slidably engage the housing half second edge portion and an opposite face configured to slidably engage the second seat surface of the associated end portion of the shaft, and an elongate connector adjustably connecting the clamp block to the wedge member and configured to controllably adjust a distance between the clamp block and the wedge member, whereby the wedge lock assembly is configured to clamp the associated end portion of the shaft between the wedge member and the first edge portion of the housing half.
