Abstract

A spinning ring for a ring-spinning or ring-twisting machine includes a web and a ring crown, the ring crown having a contact surface along which a ring traveler slides in operation of the ring-spinning or ring-twisting machine. At least the contact surface of the ring crown formed of a tungsten sintered material having at least 90% tungsten. A ring/traveler system using the spinning ring includes a ring traveler made of a wire made of high-speed steel (HSS) having a minimum hardness of 60 HRC.

Abstract

A driven ring assembly for a ring-spinning or ring-twisting machine includes a ring and an electric drive having a stator and a rotor with a magnet. A ring crown is on the ring and a ring traveler is on the ring crown. A connecting portion is between the ring and the rotor. The electric drive includes coil winding strands in the stator that generate a torque and radial forces. An axial degree of freedom and tilting degrees of freedom of the rotor are passively stabilized by reluctance forces and radial degrees of freedom of the rotor are actively stabilized by a control loop controlling current through the coil winding strands.

Abstract

The invention relates to a driven ring for a ring-spinning or ring-twisting machine, having an electrical drive (11) having a stator (12) and a rotor (13) with a magnet (17), wherein the ring comprises a ring crown (15), for attachment of a traveller (10), and a connecting section (16), and the ring is connected for conjoint rotation to the rotor (13) of the drive (11) via the connecting section (16). The drive (11) has a coil system for generating a torque and radial forces, wherein an axial degree of freedom (26) and both tilting degrees of freedom (27, 28) of the rotor (13) are stabilised passively by reluctance forces, and both radial degrees of freedom (29, 30) are stabilised actively by a control circuit.
