Bearing and drive structure for spinning turbine

A bearing and drive structure for a funnel-shaped spinning element of an open-end spinning turbine, comprising:

• a stator having a bearing supporting part;
• a stationary component of a journal bearing including a bearing bush having an opening for receiving a rotary component, and means elastically mounting said bush to said stator bearing supporting part;
• a pin element connected to the spinning element and having an end portion constituting the rotary component received in said opening of said bush;
• a rotor having a cup-shaped part enclosing said stator part and having a front end to which said spinning element is connected to rotate with said rotor;
• electrical windings on said stator cooperating with said rotor to form an electrical drive for rotating said rotor;
• said rotor part having an axially compact configuration for causing its largest central principal moment of inertia to be about its axis of rotation;
• said journal bearing stationary component being located within the region enclosed by said cup-shaped rotor part;
• and
• said rotor part being formed to locate the center of gravity of said rotor in a plane normal to the axis of rotation of said stator and at least approximately located between the axial ends of said journal bearing stationary component.
