At least one of the first surface and the second surface including a profile oriented at an oblique angle relative to a plane of the rack.
Claims21
A drive mechanism for a mining machine, the drive mechanism configured to engage and move the mining machine along a rack, the drive mechanism comprising:
- a gear configured to engage the rack, rotation of the gear causing movement of the mining machine along the rack;
- and
- a guide shoe for maintaining engagement between the gear and the rack, the guide shoe including a first wall, a second wall extending orthogonally from a first end of the first wall, a third wall extending orthogonally from a distal end of the second wall, and a fourth wall extending orthogonally from a second end of the first wall, the fourth wall having a planar surface oriented at an oblique angle relative to the second wall, wherein the planar surface is configured to engage a surface of the rack.
A drive mechanism for a mining machine, the drive mechanism configured to engage and move the mining machine along a rack, the drive mechanism comprising:
- a gear configured to engage the rack such that rotation of the gear moves the mining machine along the rack;
- and
- a guide shoe for maintaining engagement between the gear and the rack, the guide shoe including a wall providing a hook,
- wherein the rack includes a rail adjacent to the guide shoe and having a planar surface configured to engage the hook, the rail including a first edge and a second edge, the planar surface positioned on the first edge, the planar surface being oriented at an oblique angle relative to the second edge, a distance between a first end of the first edge and the second edge being less than a distance between a second end of the first edge and the second edge.
An interface between a guide shoe of a mining machine and a rack, the interface comprising:
- a first surface positioned on the guide shoe, the guide shoe including a first wall, a second wall extending orthogonally from a first end of the first wall, a third wall extending orthogonally from a distal end of the second wall, and a fourth wall extending orthogonally from a second end of the first wall, the fourth wall including the first surface;
- and
- a second surface positioned on the rack, the rack including a rail and a plurality of teeth, the second surface positioned on the rail,
- wherein the first surface has a concave profile and the second surface has a convex profile that is complementary to the concave profile.
