Definitions

  • the invention relates to a spinning rotor assembly for a rotor spinning machine as well as a rotor spinning machine.
  • Rotor spinning machines are widely used for processing fiber material or roving into workable yarn or thread by a spinning rotor of a spinning rotor assembly.
  • Such spinning rotor assemblies comprising the spinning rotor connected to a rotor shaft as well as at least one bearing unit are typically used in spinning machines, in particular in open-end rotor spinning machines.
  • Such open-end rotor spinning machines are operated at speeds of 100,000 rpm and above.
  • the spinning rotor is typically arranged in a housing to protect an operator from being injured and to avoid any contact of the rotating spinning rotor with other parts of the rotor spinning machine or with materials in the surrounding environment. Accordingly, it is particularly important to quickly stop the rotation of the spinning rotor when the housing is opened.
  • opening the housing including a movement of the fast-rotating spinning rotor would lead to huge forces acting upon the spinning rotor assembly and in particular on the at least one bearing unit rotatably mounting the spinning rotor shaft to the housing, which might result in a wear or even a damaging of the spinning rotor assembly.
  • a further objective of the invention may also be to propose a rotor spinning machine which automatically stops the fast-rotating spinning rotor quickly when the spinning rotor in operation becomes accessible and in particular when a housing is opened or pivoted.
  • the spinning rotor assembly for a rotor spinning machine comprises a spinning rotor fixed to a spinning rotor shaft, the spinning rotor shaft being rotatably mounted to a housing of the spinning rotor assembly by at least one bearing unit, wherein the spinning rotor assembly is movable, in particular pivotal, between a first and a second position.
  • the spinning rotor assembly further comprises a rotor brake for braking the spinning rotor, which is pivotally mounted to the housing, so that the rotor brake is automatically engaged when the spinning rotor assembly is moved, in particular pivoted from the first to the second position.
  • the invention further relates to a rotor spinning machine with a spinning rotor assembly according to the invention, wherein the spinning rotor assembly is preferably a part of a spinbox of the rotor spinning machine and wherein most preferably the rotor spinning machine comprises several, in particular identical spinboxes.

  • the rotor brake can be used to stop the spinning rotor at a defined time and/or in a defined position, in particular in a defined rotational position of the rotor assembly.
  • the rotor brake favorably protects the bearing units from being damaged due to high forces resulting from movement, in particular tilting or pivoting the fast-rotating spinning rotor by an operator.
  • the rotor brake might also be used to adjust the forces acting upon the bearing units according to specifications of the bearings.
  • the rotor brake might advantageously be used to abruptly stop the spinning rotor to clean the spinning rotor from dust of the fiber material or roving supplied to the spinning rotor and/or of the yarn or thread produced in the spinning rotor.
  • the rotor spinning machine might be any machine for processing fiber material or roving into workable yarn or thread by a spinning rotor.
  • the rotor spinning machine might comprise only one single rotor, in particular arranged in a spinbox.
