摘要
A tunnel boring machine (100) includes a cutterhead assembly (102) rotatably mounted to a forward shield assembly (116) through a cutterhead support assembly (110). The cutterhead support assembly is configured to receive a variable number of drive assemblies (105), such that the number of drive assemblies may be selected after fabricating the cutterhead support structure (120). The cutterhead support structure includes a housing portion (121) that houses the main bearing assembly (101) and a drive gear (104). A plurality of drive mount stations (111) provide access to the drive gear, and are provided with a pinion housing (130) for stations that receive a drive assembly, or with a cradle cover (140) for stations that do not receive a drive assembly.
