Abstract:
A bearing arrangement for rotatably supporting a rotor shaft of an open end spin rotor, comprising pairs of support disks arranged so as to define a notch in which said rotor shaft is rotatably supported, each of said support disks further comprising a basic body and a rim fitted thereon, said rim defining an outer circumferential contact surface against which said rotor shaft rests; and at least one cleaning groove defined in said contact surface of at least one said disk of each said pair of disks, said cleaning groove comprising a continuous endless groove defined between continuous circumferential edge sections of said contact surface and having a shape and angular configuration so as not to coincide with a middle axis of said contact surface to cause a cleaning of said rotor shaft as said rotor shaft rotates in said notch against said contact surfaces.
