Abstract

The invention relates to an open-end spinning device with a spinning rotor (1), the shaft (3) of which passes through an aerostatic radial bearing (9) with a gap (9) between the support device and the shaft (3). 5) are radially supported, and an aerostatic radial bearing for this purpose. According to the present invention, the start-up spinning device also constitutes: the bearing surface of the spinning rotor (1) and / or the bearing surface of the radial bearing (5) is made of a polyimide or Kevlar (keular) of. Even in the unlikely event that contact of the bearing surfaces occurs, the service life of the radial bearing is thereby significantly increased.

Description

technical field

[0001] The invention relates to an open-end spinning device with a spinning rotor whose shaft passes through an aerostatic radial bearing with a gap provided between the bearing device and the shaft and the used aerostatic radial bearing. Bearings support it in the longitudinal direction. Background technique

[0002] In a known open-end spinning device (JP57-27212), the shaft of the spinning rotor is always supported in a radial bearing on its front and rear ends. The compressed air coming from the rear, which has passed through the bearing surface of the radial bearing, is guided through holes into the interspace between the bearing surface of the radial bearing and the bearing surface of the spinning rotor. During normal operation, the aerostatic bearing enables a wear-free and friction-resistant construction of the spinning rotor.

[0003] However, in the course of the rotation of the spinning device at the start, there are occasions when uneven operati...
