SPINNING ROTOR ASSEMBLY FOR ROTOR SPINNING MACHINE

The invention relates to a spinning rotor assembly for a rotor spinning machine as well as the rotor spinning machine. In order to propose a rotor assembly of a rotor spinning machine which can be securely operated, in particular to avoid an injury of a user operating the rotor spinning machine and to prevent materials in the environment of the rotor spinning machine from being entangled in the fast-rotating spinning rotor, the spinning rotor assembly comprises a spinning rotor fixed to a spinning rotor shaft, the spinning rotor shaft is 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 pivotally between a first position and a second position, and a rotor brake for braking the spinning rotor 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. 本发明涉及用于转杯纺纱机的纺纱转杯组件。还涉及转杯纺纱机。
