Abstract:
A process for reworking an open-end rotor spinning apparatus, said process comprising of the steps;dismounting a bearing block from the open-end spinning apparatus, the bearing block maintaining support disks that form a V-notch in which a rotor shaft of a spin rotor resides and possessing a ball axial bearing abutting an end of the rotor shaft distal to the rotor; separating the ball axial bearing from the bearing block forming a separating surface on the bearing block where separation occurs; matching a complementary surface on an axial bearing carrier for a pneumatic axial bearing to the separating surface of the bearing block; aligning the axial bearing carrier with the bearing block to insure proper placement of the axial bearing carrier relative to the rotor shaft of the spin rotor; fastening the axial bearing carrier to the bearing block in a manner that maintains alignment of the axial bearing carrier relative to the rotor shaft of the spin rotor, adjusting the alignment as need; and reinstalling the bearing block back into the open-end spinning apparatus.
