Definitions

  • the collar can be an integral part of the rotor shaft.
  • the collar is preferably not designed as an integrated component of the rotor shaft, but is releasably attached to this rotor shaft.
  • the federal government can be designed differently.
  • FIG. 2 shows another advantageous embodiment of a collar 3.
  • the collar 3 is formed by a second clamping disk 31, which is arranged on the centering section 2 of the rotor shaft 20.
  • the tensioning disks 4 and 31 are placed on the centering section 2 in such a way that their curved middle section with the inner edge 41 and 32 is at a distance from the rotor base 10, while its outer edge 12 and 33 is already in contact with the rotor base 10.
  • the tensioning disk 31 is thus arranged outside the spinning rotor 1 in the opposite arrangement to the tensioning disk 4 arranged in the interior of the rotor on the centering section 2.
  • the spinning rotor 1 is fastened here in the same manner as was explained with reference to FIG. 2.
  • the base 51 of this rotor 5 is only arranged between the tension disk 4 in the rotor interior 10 and the tension disk 31 forming the collar 3.
  • the collar 3 - which in principle can also be configured differently from FIG. 3 - and the tensioning disk 4 thus serve not only to fasten and clamp the spinning rotor 1, but also to fasten the rotor 5 to the journal 21. The fastening takes place in the previously described manner.
  • the design of the rotor shaft 20 is not tied to the designs shown. Rather, each element is understood independently of its shape and length, which serves to support the spinning rotor 1.
  • the term “rotor shaft” also includes tubular and sleeve-like designs.
