Definitions

  • an outer tube (2) is rotatably mounted on a drilling shaft (1).
  • the free end of the drilling shaft carries the usual receptacle (3) for a drilling tool, which is not shown in FIG. 1.
  • the outer tube (2) is supported with a front axial-radial bearing (4) on the drilling shaft, which in turn is hollow-cylindrical, which results in a central channel (5) which supplies the descending flow of the drilling fluid to the drilling tool and the ascending current of the drilling fluid supplied, which discharges the cuttings detached from the drilling tool from the borehole.
  • the outer tube (2) is also supported on the drilling shaft (1) by a further axial / radial bearing (6) at its end opposite the receptacle (3).
