摘要： A cutting assembly for a mining machine includes a mount configured to move about a first axis relative to a chassis of the mining machine and a ranging arm coupled to the mount. The ranging arm is moveable relative to the mount. The cutting assembly includes a cutting head having a housing coupled to the ranging arm. The housing is moveable relative to the ranging arm. The cutting head includes a drum supported for rotation relative to the housing about a rotational axis, a plurality of cutting bits coupled to the drum, and at least one motor supported by the housing to drive the drum about the rotational axis.

摘要： A cutting assembly is configured to be coupled to a chassis of a mining machine. The cutting assembly includes a ranging arm configured to pivot about a pivot axis relative to the chassis, a motor supported by the ranging arm for the motor to move with the ranging arm about the pivot axis, and a drum including a plurality of cutting picks. The drum is supported by the ranging arm to be driven about a rotational axis by the motor. The cutting assembly includes a pitch adjustment actuator coupled to the ranging arm. The pitch adjustment actuator is operable to move the drum about a pitch axis. The pitch axis extends in a direction between the pivot axis and the rotational axis.

摘要： A cutting device support for a mining machine includes a ranging arm, a bracket positioned adjacent an end of the ranging arm, and a thermally-expandable coupling member positioned between the bracket and the ranging arm. The coupling member exerts a force on the bracket and the ranging arm to secure the bracket to the ranging arm.
