Definitions

  • FIG. 3 is a schematic diagram of a perspective along the direction X in FIG. 2 .
  • the spacing parts 3 arranged on the axis 2 carry the cogs 6 formed by a first half disk 7 and a second half disk 8.
  • the cog 6, i.e., the half disks 7 and 8, is provided with the teeth 9 on the outer periphery thereof.
  • each of the half disks 7 and 8 comprises three teeth 9.
  • the half disks 7 and 8 are fixed on the spacing parts 3 by the bolts 10.
  • the bolts 10 are arranged on the center circle 11, wherein the bolts 10 are arranged with the longitudinal axis thereof in parallel to the shaft axis 2.
  • the half disks 7 and 8 are arranged, in the order thereof in the direction of the shaft axis 2, to have radial rotation by the angle ⁇ .
  • the angle ⁇ is also obtained from the misalignment of the teeth 9 of consecutive cogs 6 in the rotation by the angle ⁇ .
  • the angle of inclination ⁇ and the rotation angle ⁇ With a combination of the angle of inclination ⁇ and the rotation angle ⁇ , visible varying inclination of the cog 6 relative to the axis 2 is achieved (see FIG. 1 ). The reason thereof is because the plane where the inclined cogs 6 are located similarly rotates about the axis 2 due to the rotation of two consecutive cogs 6. Since the cogs 6 are inclined by ⁇ , the cogs 6 sweep over an operating area along the longitudinal direction of the axis 2 on the periphery of the extraction roller.
