Open-end spinning rotor for use in textile industry, has spring element that is stretched during insertion of stub into borehole such that element transfers torque from shaft to cup, where element is detachably connected with cup and shaft

摘要

The rotor (1) has a rotor shaft (3) and a rotor cup (2) detachably connected with one another. A shaft stub (5) is firmly connected with the cup and inserted into a borehole (4) in the shaft. The stub and the borehole have a circumferential groove (6) in which a spring element (8) is arranged such that the element projects over the groove. The element is stretched during insertion of stub into the borehole such that the element transfers torque from the shaft to the cup. The element is detachably connected with the cup and the shaft. The element is made of spring steel.
