Abstract
Spinning rotor (1) for an open end rotor spinning machine comprising a rotor shaft (2), a rotor cup (3), which has an opening (4), an inner chamber (5), a rotor groove (6), a conically widening slide wall (7) extending from the opening (4) to the rotor groove (6) and a rotor base (9) arranged opposing the opening (4) and designed with a bore (8), through which the rotor shaft (2) extends at least partially. The rotor shaft (2) is connected by means of a connection element (10) to the rotor cup (3) and the rotor shaft (2) and rotor cup (3) comprise a common rotational axis (13). The rotor shaft (2) and the rotor cup (3) have connection means (11, 12), which are at least partially surrounded by the connection element (10) configured as a cast part, so a positive connection of the rotor shaft (2) to the rotor cup (3) can be achieved.
