Abstract

In a driving arrangement for the cutting heads or rolls of an advancing or mining machine having the cutting heads or rolls rotatably supported on a cantilever arm at both sides thereof and having the driving shaft rotatably supported within the interior of the cantilever arm (1), the output shafts (2) are supported in mutually coaxial relation at the free end of the cantilever arm (1) and carry at their respective mutually facing inner ends a gear wheel (3) being in meshing engagement within the interior of the cantilever arm with a common paraxial intermediate gear wheel (4). In this case, the mutually facing inner ends of the output shafts (2) are supported on a common bearing carrier (13) being stationary relative to the cantilever arm (1), and the output shafts (2) comprise a central cavity (19) extending in axial direction. The output shafts (2) are non-rotatably connected with the heads or rolls. Preferably, the bearing carrier (13) extends through the axes of the output shafts (2) and carries axial tubular protrusions (20) extending through the cavity (19) of the output shafts, noting that conduits (21) for the supply of pressurized cooling liquid are connected to the bearing carrier (13).
