Abstract

A drum cutter mining machine includes a machine frame with a winch having a drive wheel to engage a rack or chain which extends along the path of travel by the mining machine to propel the machine along a mine face. The mining machine is made up of discrete units which include a machine body and machine housings joined to opposite sides of the machine body. The winch is either coupled through a drive train with a feed drive motor or coupled to the drive motor for cutter drums. The machine housings each support a pivot shaft coupled by an arm to a drum cutter. One of these housings includes a removable end cover and a recess adapted to receive a support housing for a spur gear system used to transmit torque from a feed drive motor to a reduction gear system which is, in turn, coupled to the drive wheel of the winch. In one embodiment, a removable end cover on the machine housing provides access to the feed drive motor. The feed drive motor is arranged so that the rotational axis of its drive output shaft extends transversely to the stow side of the machine frame. In another embodiment, the reduction gear system is arranged at one side of the pivot shaft for the cutter drum while the drive motor therefor is arranged at the other side of the pivot shaft and coupled thereto through the spur gear system. In a further embodiment, the reduction gear system is disposed between the feed motor and the pivot shaft. [USPTO]

Claims

We claim as our invention:

1. A drum cutter mining machine adapted for movement along a mine face including the combination of:

a machine frame including a machine body and machine housings joined to the opposite ends of the machine body,

a cutter drum including a support arm carried by each of said machine housings,

drive motor means supported by said machine frame,

means extending along the course of travel by the mining machine for propelling movement thereof along the mine face,

a drive wheel carried by at least one of said machine housings to engage said means extending along the course of travel,

a drive gear means carried by each of said machine housings to transmit torque from said drive motor means to the cutter drum supported thereby, and

a drive train carried by the same machine housing which carries said drive wheel to transmit torque thereto from said drive motor means for propelling movement of said machine frame along the mine face.

2. The drum cutter mining machine according to claim 1 wherein said drive motor means includes a feed drive motor mounted within the machine housing carrying said drive wheel, said feed drive motor having the torque output shaft at the stow side arranged such that the rotational axis thereof extends transversely to the course of travel by the mining machine, and wherein said drive train includes a spur gear system coupled with reduction gearing between said feed drive motor and said drive wheel.

3. The drum cutter mining machine according to claim 2 wherein said drive motor means further includes a cutter drive motor for rotating the cutter drums carried by said machine housing.

4. The drum cutter mining machine according to claim 2 further including a pivot shaft coupled to said support arm of a cutter drum for support by one of said machine housings, said feed drum motor being supported in one of said machine housings between said pivot shaft and a cutter drum while supported by the pivot shaft, said reduction gearing including a planetary gear system arranged with said drive wheel at one side of said pivot shaft for support by one of said machine housings.

5. The drum cutter mining machine according to claim 4 wherein said planetary gear system and said drive wheel are supported in the machine housing between said pivot shaft and said feed drive motor.

6. The drum cutter mining machine according to claim 4 wherein said planetary gear system and said drive wheel are supported in the machine housing at the side of said pivot shaft facing away from said feed drive motor.

7. The drum cutter mining machine according to claim 1 wherein said drive motor means includes a feed drive motor supported by one of said machine housings for providing torque to only move said machine along the course of travel, said drum cutter mining machine further including a pivot shaft coupled to said support arm of a cutter drum for support by one of said machine housings, said feed drive motor being arranged at the side of said pivot shaft facing away from the cutter drum coupled thereto through a support arm, said drive train including a spur gear system coupled through a reduction gear system to said drive wheel, said drive gear means including a shaft member extending in a vertically-spaced transverse relation across said feed drive motor, said drive motor means further including a cutter drum drive motor coupled by said drive gear means including said shaft member to rotate the cutter drum supported by the pivot shaft on the machine housing.

8. The drum cutter mining machine according to claim 1 wherein said machine frame further includes at least one detachable gear housing, at least one of said machine housings including an opening at the stow side thereof for supporting said gear housing, said drive train including a reduction gear system and spur gear system located within said detachable gear housing.

9. The drum cutter mining machine according to claim 8 further including horizontal support fasteners carried by the said at least one of said machine housings having an opening at the stow side, said detachable gear housing having a mounting opening to receive said horizontal support fasteners.

10. The drum cutter mining machine according to claim 2 or 3 wherein said machine housing mounting said feed drive motor includes a detachable end wall, and wherein said drive train includes a support housing with a spur gear system for central mounting of said feed drive motor to said support housing adjacent said detachable end wall.

11. The drum cutter mining machine according to claim 2 or 3 wherein said machine housing mounting said feed drive motor includes a detachable end wall having a recess dimensioned to receive said feed drive motor.

12. The drum cutter mining machine according to claim 2 or 3 wherein said housing mounting said feed drive motor includes a detachable end wall and wherein said drive train includes a support housing with a spur gear system for central mounting of said feed drive motor to said support housing adjacent said detachable end wall, said support housing includes a feed drive motor centering member, said drive train further including a reduction gear system with said spur gear system, the length of said centering member being less than the width of said coupling teeth.
