Abstract:
A rotor bearing arrangement for a spinning rotor of a spinning device in an open-end spinning machine, wherein said spinning machine includes at least two adjacently disposed said spinning devices with said respective rotors having rotor shafts disposed in a common plane and driven by a common tangential belt, said bearing arrangement comprising:at least two bearing disks configured to support and be driven by said rotor shaft, said bearing disks having a respective axis of rotation and defining a nip in which said rotor shaft rests; one of said bearing disks being disposed in a leading position relative to a direction of travel of said tangential belt and rotatable in a circumferential direction into said nip; said other bearing disk disposed in a trailing position relative to a direction of travel of said tangential belt and rotatable in a circumferential direction out of said nip; and wherein a vertical distance between said axis of said leading position bearing disk and said common plane of said rotor shafts is less than a vertical distance between said axis of said trailing position bearing disk and said common plane of said rotor shafts.
