ABSTRACT:
An opening roller unit for open-end spinning installations as a shaft supported in a bearing box and an opening roller arranged on an end of the shaft which projects from the bearing box. The opening roller extends over the bearing box in a manner forming a cavity that is sealed toward the outside with an annular sealing gap and comprises the base member and the ring detachably secured thereto which has a fitting provided on the outer periphery thereof. The detachable ring is mounted upon the base member in a manner blocking the external axis to the cavity. In accordance with one preferred embodiment, the ring of the opening roller extends over the bearing box and the cavity is defined by the ring and bearing box, while the scaling gap is provided between the ring and the bearing box in conjunction with an annular insert attached to the bearing box. In an alternative embodiment, the base member extends over the bearing box and defines the cavity in conjunction therewith, while the detachable ring blocks axis to the cavity by covering radial openings formed in the base. In accordance with an advantageous feature, the frictional connection between the base member and the ring secured thereto is provided by an annular spring band received within an annular groove provided on an outer surface of the base member.
