Shaft arrangement for supporting and driving an open-end spinning rotor










Image Number 2 for United States Patent #5979155.

In open-end rotor spinning devices, an axial engagement element, typically a ceramic pin, is inserted as a wear protector in a receptacle at the free end of the rotor shaft which is supported on a ball of an axial bearing. In order to receive the air displaced during the insertion of the axial engagement element, the free end of the shaft is formed with at least one radial bore connecting the receptacle with the ambient environment through which the air displaced during the insertion can escape.
