Embodiment Construction

[0022] figure 1 and 2 The open textile machine 1 shown in contains a textile machine rotor 2 and a tangential drive belt 3 . The textile machine rotor 2 consists of a rotor disk 4 and a rotor shaft 5 . A tangential drive belt 3 runs through the machine in the direction of travel A and a rotor shaft 5 drives a plurality of textile machine rotors 2 arranged next to each other. During operation, the rotor disk 4 rotates in the vacuum chamber 6 of the rotor housing 7 . The negative pressure chamber 6 is connected to a negative pressure source in a manner not shown. The front opening 8 of the rotor housing 7 is closed with a cover element 10 which can be pivoted away about a pivot axis 9 for maintenance purposes. The ring seal 11 here provides a seal between the cover element 10 and the rotor housing 7 .

[0023] A substantially rotationally symmetrical exchangeable adapter 12 is arranged on the cover element 10 , which during operation partially protrudes into the interior of...

Abstract

The invention relates to an open-end spinning device containing at least one spinning rotor. The spinning rotor is rotatably mounted in two radial bearings by means of a rotor shaft. The open-end spinning device further contains a tangential belt for driving the rotor shaft. The radial bearings are arranged in an easily exchangeable bearing unit, wherein the open-end spinning device has at least one contact surface for positioning the bearing unit. Two bearing units that can be alternately used in the open-end spinning device are provided, of which a first bearing unit has direct radial bearings and a second bearing unit has indirect radial bearings. For both bearing units, the position of the rotor shaft relative to the contact surface of the bearing unit is the same.

Description

technical field [0001] The invention relates to an open textile machine having at least one textile machine rotor, which is mounted rotatably via a rotor shaft in two radial bearings and has a tangential drive belt for driving the rotor shaft. Background technique [0002] In open textile machines currently available on the market there are only two solutions of how to support the rotor shaft directly driven by a tangential drive belt. [0003] A first type of bearing is called "indirect bearing" and is disclosed, for example, in DE 10 2006 001 449 A1. The rotor shaft is supported on two pairs of washers, additionally a thrust bearing is provided which ensures the radial positioning of the rotor of the textile machine. The drive belt sliding surface is arranged roughly in the middle of the rotor shaft. A tangential drive belt runs between the two washer pairs. [0004] A second type of bearing is called "direct bearing" and is disclosed, for example, in DE 10 2008 010 366...
