Spinning rotor with a running coating, thrust ring to the mounting of a spinning rotor as well as open nend spinning device with a spinning rotor, and a support with supporting disks

摘要

A spinning rotor (1) for an open nend spinning device with a rotor shaft (2), via which the spinning rotor (1) in a wedge-shaped gap (4) of supporting disks (5) of a bearing device (6) of the open radially nend spinning device is supported rotatably, has at least one bearing region (7), which is connected with a tread layer (8), in particular a tread layer (8) of a plastic material, is provided. A supporting disk (5) has a base body (10) and provides at its outer circumference a running surface (11) for the radial support of the spinning rotor (1) ready. The running surface (11) of the supporting disc (5) is formed by the outer circumference of the base body (10) of the supporting disc (5) is formed.
