Embodiment Construction

[0021] 1 and 2 show a known spinning pot 1 . The carrier plate 3 and the pivot tube 4 are fastened to the beam 2 of the rotor spinning machine as part of the frame. The cover 5 comprises structural elements for fiber supply, fiber opening and fiber feeding into the spinning rotor 6, which are not shown in detail in the figures. The spinning rotor 6 is mounted by means of a bearing arrangement 7 in the rotor housing, which bearing arrangement comprises an elastic damping sleeve 8 and ball rows 9 , 10 . The elastic damping sleeve 8 has support flanges 20 , 21 on each side, the diameters of these flanges being slightly smaller than the diameter of the holes of the rotor housing 11 . The bearing flanges 20, 21 serve to limit the deflection of the bearing arrangement 7 under load. This prevents this deflection from producing an inclination of the position of the rotor shaft 12 (in which the spinning rotor 6 contacts, for example, feed and take-out nozzles, which are not shown for...

Abstract

The invention relates to a rotor brake for a spinning rotor. The rotor shaft of the spinning rotor of a rotor spinning frame is directly mounted in a rotor housing and can be braked down to standstill by means of a rotor brake that is configured as a shoe brake acting upon the rotor shaft. The spinning chamber surrounding the rotor cup of the spinning rotor is closed during spinning by means of a lid element articulated to the rotor housing. A detent latch (23) is mounted on the rotor housing so as to be swiveled and is articulated to a brake lever (26) carrying the brake lining (27) of the rotor brake (22). During spinning, the brake lining (27) is not in contact with the rotor shaft. When the spinning chamber is opened, the lid element and the rotor housing are swiveled simultaneously due to their articulated connection. The movement of the rotor housing is limited by a stop against a frame part of the rotor spinning frame. In the stop position, the brake line (27) of the brake lever (26) is pressed against the rotor shaft by means of a spring element. The inventive rotor brake (22) allows to avoid a sudden overload of the bearing of the spinning rotor.

Description

technical field [0001] The invention relates to a rotor brake for a spinning rotor of a rotor spinning machine according to the preamble of claim 1 . Background technique [0002] In known designs of rotor spinning machines, the shaft of the spinning rotor is mounted in double row roller bearings. The driving of such structures is usually carried out by means of tangential belts which engage directly on the shaft of the spinning rotor. The bearing arrangement of the rotor shaft is clamped in a resilient damping sleeve held in the rotor housing. The rotor housing is pivotally mounted on a housing portion that includes means for supplying, opening and feeding fibrous material. The housing part itself is pivotally held on the stationary frame part of the rotor spinning machine and is fixed by locking in the spinning position required for the spinning process. To open the spinning pot, the lock should be released and the rotor housing and housing part should be manually pivot...
