Rack drive for a drum cutter mining machine
Patent
·
OSTI ID:6467715
A hollow gearwheel has internal teeth that mesh directly or through an intermediate gear with the teeth of a drive gear of a machine drive on a drum cutter mining machine. External teeth on the hollow gearwheel mesh with the teeth of a rack extending over the distance traversed by the mining machine along the face of a longwall mine. A plate pivots about the rotational axis of the drive gear while the plate forms a closure to the side of the hollow gearwheel facing the mining machine. The plate carries a bearing support for the arbor shaft of the hollow gearwheel and forms a seal along the outer peripheral edge of the hollow gearwheel. A carrier includes a bearing to support the outer end of the arbor shaft. The carrier is moved along a recess in a housing for the hollow gearwheel to adjust, by pivotal positioning, the hollow gearwheel.
