Brake for an open-end spinning rotor

Abstract

A rotor brake ( 8 ) for an open-end spinning rotor rotating at a high speed in a rotor housing. The open-end spinning rotor is rotatably supported by its rotor shaft ( 2 ) in the bearing nip ( 3 ) of a support-disk bearing ( 4 ). The rotor brake ( 8 ), which is preferably designed in a tong-like manner, comprises brake levers ( 9, 10 ) that can be placed on the rotor shaft ( 2 ) and comprise a replaceable brake lining ( 16 ) on their end. The brake lining ( 6 ) is manufactured from sintered bronze.

What is claimed is:  
     
         1 . A brake for an open-end spinning rotor rotatably supported for high speed rotation in a rotor housing by a rotor shaft disposed in a bearing nip of a support-disk bearing, the brake comprising at least one brake lever having a brake lining comprised of sintered bronze, the brake lever being disposed for selective braking movement into and out of engagement with the rotor shaft.  
     
     
         2 . The brake according to  claim 1 , wherein the brake lining is fixed to the brake lever via a detachable fastener assembly for selective replacement.  
     
     
         3 . The brake according to  claim 2 , wherein the brake lining comprises a fastening slot open at the bottom into which extends a centering extension of the fastener assembly in an assembled state.
