摘要： A rackbar for a mining machine has a body including a first end and second end, an inner rack wall, an outer rack wall spaced from the inner rack wall, a plurality of gear teeth extending between the inner rack wall and the outer rack wall, an extension disposed adjacent the first end, a pin aperture positioned on the extension, and a rib extending along a surface of the extension. The inner and outer rack walls extend between the first end and the second end parallel to a rack axis. The extension extends in a direction perpendicular to the rack axis. The pin aperture is configured to receive a pin.

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.

摘要： A guide shoe for a mining machine includes a shoe body, a through hole, and a support. The shoe body is configured to engage a rack. The through hole extends between a first wall of the shoe body and a second wall of the shoe body, and the through hole extends along a central axis. The support is coupled to the first wall, and the support is configured to engage a shaft coupled to a drive sprocket engaging the rack. At least one of the shaft and the support is movable between a first configuration and a second configuration. The rotation axis is spaced apart from the rack by a first sprocket distance in the first configuration, and the rotation axis is spaced apart from the rack by a second sprocket distance in the second configuration.
