Problems solved by technology

A further disadvantage of the known godet is that the magnetic bearing with its bearing pole winding can only be used if the godet housing has a correspondingly large outer diameter, especially if the godet load is dictated by the yarn guidance. Bearing pole windings are required to have the smallest possible pole dimensions

Embodiment Construction

[0029] 1 and 2 show a first embodiment of a godet roller according to the invention. Figure 1 shows the main godet roller part of the present invention by means of a section parallel to and passing through the axis of rotation, figure 2 a to 2g are described by means of a cross section perpendicular to the axis of rotation corresponding to the supporting plane.

[0030] Therefore, if there is no explicit reference to a certain drawing, the following description applies to both drawings. The embodiment of the godet roller according to the invention has a godet roller housing 1 which is connected non-rotatably to a shaft 3 extending in the godet roller housing 1 via an end wall 2 and a hub 16. The shaft 3 is connected to the motor shaft 8 of the motor 9 through a coupling 7 at the other end thereof. The motor 9 formed as a motor is not shown in detail in FIG. 1.

[0031]The godet roller housing 1 is supported on a cantilever bracket 4 via a radially acting magnetic bearing 13. The ...

Abstract

A godet roll for guiding at least one yarn on the circumference of a hollow-cylindrical godet roll casing. The godet roll casing is rotatably seated on a projecting support by a bearing arrangement which includes a radially acting magnetic bearing having a plurality of bearing pole windings distributed in the circumferential direction on the support. The bearing pole windings are arranged on the support at spacings from one another circumferentially about the support and also at spacings along the support in a plurality of adjacent bearing planes in order to make possible a low-vibration guidance of the godet roll casing.

Description

Technical field [0001] The invention relates to a godet roller for guiding at least one filament. It has: an empty cylindrical godet roller shell, the filament is guided on its circumference; a cantilever bracket, the godet roller shell passes through a plurality of The bearing is rotatably supported on the bracket, wherein at least one bearing is a radially acting magnetic bearing, which has a plurality of bearing pole windings distributed in the circumferential direction on the bracket. Background technique [0002] A godet roller of this type is known from EP0770719B1. [0003] The known godet roller has a godet roller housing connected to a motor, which is supported on a bracket. In order to support the godet roller shell, two magnetic bearings are arranged at a certain distance from each other, and each magnetic bearing has a plurality of bearing pole windings. Here, the bearing pole winding of the magnetic bearing is mounted on a bracket in the supporting plane, that is to ...
